A pipe whose diameter measures 1 1/4 inches should have less threads per inch than a pipe with a diameter of 11/2 inch. So, the correct answer is (D).
To determine the correct answer, we need to compare the diameters of the two pipes and understand the relationship between pipe diameter and threads per inch.
The number of threads per inch generally decreases as the pipe diameter increases. This means that a larger pipe diameter will have fewer threads per inch compared to a smaller pipe diameter.
Given that the first pipe has a diameter of 1 1/4 inches, we need to find the pipe diameter from the options that is larger than 1 1/4 inches.
The option that meets this requirement is D. 11/2. This represents a pipe diameter of 1 1/2 inches. Therefore, a pipe with a diameter of 1 1/2 inches should have fewer threads per inch than a pipe with a diameter of 1 1/4 inches. Therefore, the correct answer is D. 11/2.

Mr. John recently bought 2 cords of wood from a local contractor
(delivered in a dump truck). After the pile was dropped off, he stacked
the wood and wondered if he really received the 2 standard cords of
wood (see diagram) or if the company sold him less wood than he
ordered.
Note: a cord of wood if defined as 4ft X 4ft’ X 8ft stack
Mr. John ended up stacking to piles of wood this past week.
Mr. John ended up with two piles of wood with the following sizes
PILE #1: 72” X 167” X 16”
PILE #2: 65” X 266” X 16”
QUESTIONS:
1. Did Mr. John get more or less than 2 cords of wood (as defined in
the diagram above)?
2. If a standard piece of wood is 5” X 5” X 12”. How pieces of actual
wood did he receive based on his stacked piles?
3. If the cost for both cords of wood was actually $250/cord,
What was the cost per a standard piece of wood?
1. Mr. John received more than 2 cords of wood based on the sizes of the stacked piles.
2. Based on the stacked piles, Mr. John received approximately 11,974 pieces of actual wood.
3. The cost per standard piece of wood is approximately $0.0417.
1. To determine if Mr. John received more or less than 2 cords of wood, we need to calculate the volume of each pile and compare it to the volume of a standard cord of wood.
Calculating the volume of each pile:
PILE #1:
Volume = 72 inches * 167 inches * 16 inches = 1,523,584 cubic inches
PILE #2:
Volume = 65 inches * 266 inches * 16 inches = 2,068,480 cubic inches
Calculating the volume of a standard cord of wood:
Volume of a standard cord = 4 feet * 4 feet * 8 feet = 128 cubic feet
Since 1 foot = 12 inches, the volume in cubic inches is 128 * 12 * 12 * 12 = 221,184 cubic inches.
Comparing the volumes:
Pile #1: 1,523,584 cubic inches
Pile #2: 2,068,480 cubic inches
Standard cord: 221,184 cubic inches
It is evident that both piles have significantly more volume than a standard cord of wood. Therefore, Mr. John received more than 2 cords of wood.
2. To determine the number of standard pieces of wood received, we need to calculate the number of pieces that can be obtained from the total volume of the piles.
Total volume of the piles = Volume of Pile #1 + Volume of Pile #2
Total volume = 1,523,584 cubic inches + 2,068,480 cubic inches = 3,592,064 cubic inches
Volume of a standard piece of wood = 5 inches * 5 inches * 12 inches = 300 cubic inches
Number of standard pieces of wood received = Total volume of the piles / Volume of a standard piece of wood
Number of pieces = 3,592,064 cubic inches / 300 cubic inches = 11,973.55 pieces (rounded to the nearest whole number)
Therefore, Mr. John received approximately 11,974 pieces of actual wood based on his stacked piles.
3. To calculate the cost per standard piece of wood, we need to divide the total cost of the two cords by the number of standard pieces received.
Total cost for both cords of wood = 2 cords * $250/cord = $500
Cost per standard piece of wood = Total cost / Number of standard pieces
Cost per piece = $500 / 11,974 = $0.0417 (rounded to four decimal places)
Therefore, the cost per standard piece of wood is approximately $0.0417.

The size of angle marked n is ≈26.67 degrees.
Sparx 4:
Item A, bookwork code C20 requires us to determine the size of angle marked n in degrees.
We can solve the given question by using the angles sum rule that states that the sum of the angles of a triangle equals to 180 degrees.
The given figure represents an isosceles triangle since the two base angles are equal in length.
Also, the top line is parallel to the bottom line.
Using the angles sum rule for a triangle, we get:angle ABC + angle BCA + angle CAB = 180 degreesx + 2n + 50 = 180 degreesx = 180 - 2n - 50x = 130 - 2nWe know that angles that are opposite to equal sides of an isosceles triangle are equal.
Therefore, angle ABC = angle CAB = n
Thus, the above equation becomes:130 - 2n = n + 50.
Simplifying the equation, we get:3n = 80n = 80 / 3n ≈ 26.67 degrees.

use the basic concepts of probability to identify the following . show solution .
1: 1/5 rolling a die
The probability of rolling the specific outcome 1: 1/5 on a fair six-sided die is 1/6
To identify the probability of rolling a specific outcome on a fair six-sided die, we can use the concept of probability. The probability of an event is defined as the ratio of the number of favorable outcomes to the total number of possible outcomes.
In this case, we want to find the probability of rolling a specific outcome, which is 1 out of 5. Since there is only one specific outcome we are interested in, and the die has a total of 6 possible outcomes (numbers 1 to 6), the probability can be calculated as:
Probability = Number of favorable outcomes / Total number of possible outcomes
Probability = 1 / 6
Therefore, the probability of rolling the specific outcome you mentioned (1 out of 5) on a fair six-sided die is 1/6.
In conclusion, when rolling a fair die, each of the six possible outcomes has an equal chance of occurring, resulting in a probability of 1/6 for any specific outcome.

13 ft.
10 ft.
What is the height of the tent in feet?
Write the answer in the box.
feet
We may apply the Pythagorean theorem to calculate the height of the tent, which states that in a right triangle, the square of the hypotenuse (the longest side) is equal to the total of the squares on the other two sides. So, the height of the tent is 8.3077 feet.
In this case, the two sticks form the slanted sides of the tent, and the opening at the bottom forms the base of the triangle. We can consider the height of the tent as the missing side, which is perpendicular to the base.
Let's denote the height of the tent as 'h.' Using the Pythagorean theorem, we have:
(10 ft.)² + (h)² = (13 ft.)²
Simplifying the equation:
100 + h² = 169
Now, subtracting 100 from both sides:
h² = 169 - 100
h² = 69
Taking the square root of both sides:
h = sqrt(69)
Therefore, the height of the tent is approximately 8.3077 feet (rounded to four decimal places).

its total fixed selling expense on advertising and the remainder of the total fixed selling expense comprised the fixed portion of the
company's sales representatives' compensation.
a. When the company sells 15,500 units, what is the total direct selling expense that can be readily traced to individual sales
representatives?
b. When the company sells 15,500 units, what is the total indirect selling expense that cannot be readily traced to individual sales

1. a. The Total direct manufacturing cost is $212,350. b. The Total indirect manufacturing cost is -$128,650. 2. a. the total manufacturing cost directly traceable to the Manufacturing Department is $212,350. b. the total manufacturing cost that is an indirect cost is $83,700. 3. a. the total direct selling expense that can be readily traced to individual sales representatives is $21,700. b. the total indirect selling expense that cannot be readily traced to individual sales representatives is $38,750.
1. Assume the cost object is units of production:
a. The total direct manufacturing cost incurred to make 15,500 units can be calculated by multiplying the average cost per unit for each cost component by the number of units produced:
Total direct manufacturing cost = (Direct materials cost + Direct labor cost + Variable manufacturing overhead cost) × Number of units produced
Direct materials cost = $7.40/unit × 15,500 units = $114,700
Direct labor cost = $4.40/unit × 15,500 units = $68,200
Variable manufacturing overhead cost = $1.90/unit × 15,500 units = $29,450
Total direct manufacturing cost = ($114,700 + $68,200 + $29,450) = $212,350
b. The total indirect manufacturing cost incurred to make 15,500 units can be calculated by subtracting the total direct manufacturing cost from the average cost per unit for fixed manufacturing overhead:
Total indirect manufacturing cost = Fixed manufacturing overhead cost × Number of units produced
Fixed manufacturing overhead cost = $5.40/unit × 15,500 units = $83,700
Total indirect manufacturing cost = $83,700 - $212,350 = -$128,650
Note: The negative value indicates that the fixed manufacturing overhead cost is not fully utilized within the relevant range of production. It suggests that there may be unused capacity or fixed costs that are not being allocated to the production of 15,500 units.
2. Assume the cost object is the Manufacturing Department and that its total output is 15,500 units:
a. The total manufacturing cost directly traceable to the Manufacturing Department is the sum of the direct manufacturing costs:
Total manufacturing cost directly traceable to the Manufacturing Department = Total direct manufacturing cost
Using the values calculated in part 1a, the total manufacturing cost directly traceable to the Manufacturing Department is $212,350.
b. The total manufacturing cost that is an indirect cost and cannot be easily traced to the Manufacturing Department is the fixed manufacturing overhead cost:
Total manufacturing cost that is an indirect cost = Fixed manufacturing overhead cost
Using the value calculated in part 1b, the total manufacturing cost that is an indirect cost is $83,700.
3. Assume the cost object is the company's various sales representatives. Furthermore, assume that the company spent $44,950 of its total fixed selling expense on advertising, and the remainder of the total fixed selling expense comprised the fixed portion of the company's sales representatives' compensation:
a. When the company sells 15,500 units, the total direct selling expense that can be readily traced to individual sales representatives is the sales commissions:
Total direct selling expense = Sales commissions × Number of units sold
Sales commissions = $1.40/unit × 15,500 units = $21,700
Therefore, the total direct selling expense that can be readily traced to individual sales representatives is $21,700.
b. When the company sells 15,500 units, the total indirect selling expense that cannot be readily traced to individual sales representatives is the fixed portion of the company's sales representatives' compensation:
Total indirect selling expense = Total fixed selling expense - Total direct selling expense
Total fixed selling expense = $3.90/unit × 15,500 units = $60,450
Total indirect selling expense = $60,450 - $21,700 = $38,750
Therefore, the total indirect selling expense that cannot be readily traced to individual sales representatives is $38,750.

Is the following infinite sum defined?
0.69+1.38+2.76+5.52+…
Select the correct answer below:
The given infinite sum 0.16 + 0.4 + 0.1 + 0.25 + ... is defined as it converges to a finite value. Option A is the correct answer.
To determine whether the given infinite sum is defined, let's examine its pattern.
If we observe the terms in the sum, we can see that each term is obtained by dividing the previous term by 4. Specifically, each term is one-fourth the value of the previous term.
Let's verify this pattern:
Term 1: 0.16
Term 2: Term 1 / 4 = 0.16 / 4 = 0.04
Term 3: Term 2 / 4 = 0.04 / 4 = 0.01
Term 4: Term 3 / 4 = 0.01 / 4 = 0.0025
It appears that each term is one-fourth the value of the previous term. If this pattern continues, we can write the nth term as:
Term n = (1/4)^(n-1) * 0.16
To determine whether the sum is defined, we need to check whether the terms approach a finite value or converge to a specific value.
As n approaches infinity, the term (1/4)^(n-1) * 0.16 will approach zero since (1/4)^(n-1) approaches zero exponentially. Therefore, the sum of the infinite terms in this sequence will converge to a finite value. Hence, Option A is the correct answer.

Two cars start moving from the same point. One travels south at 50 mi/h and the other travels west at 20 mi/h. At what rate is the distance between the cars increasing 2 hours later? Round the result to the nearest hundredth.
The rate at which the distance between the cars is increasing 2 hours later is 0 mi/h, by using the Pythagorean theorem.
To find the rate at which the distance between the cars is increasing, we can use the Pythagorean theorem, which states that the square of the hypotenuse of a right triangle is equal to the sum of the squares of the other two sides.
Let's assume that after 2 hours, the distance traveled by the southbound car is d_south and the distance traveled by the westbound car is d_west.
Since the southbound car travels at a speed of 50 mi/h for 2 hours, we have d_south = 50 mi/h [tex]\times[/tex] 2 h = 100 mi.
Similarly, the westbound car travels at a speed of 20 mi/h for 2 hours, so d_west = 20 mi/h [tex]\times[/tex] 2 h = 40 mi.
Now, we can use the Pythagorean theorem to find the distance between the two cars:
[tex]distance^2 = d_south^2 + d_west^2distance^2 = 100^2 + 40^2distance^2 = 10000 + 1600distance^2 = 11600[/tex]
distance ≈ sqrt(11600) ≈ 107.68 mi
To find the rate at which the distance between the cars is increasing, we differentiate the equation with respect to time:
2 [tex]\times[/tex] distance [tex]\times[/tex] [tex]\(\frac{{d(\text{{distance}})}}{{dt}}\)[/tex] = 2 [tex]\times[/tex] d_south [tex]\times[/tex] [tex]\(\frac{{d(d_{\text{{south}}})}}{{dt}}\)[/tex] + 2 [tex]\times[/tex] d_west [tex]\times[/tex] (d(d_west)/dt)
Since d_south and d_west are constant (no mention of their rates of change), we can simplify the equation to:
2 [tex]\times[/tex] distance [tex]\times[/tex] [tex]\(\frac{{d(\text{{distance}})}}{{dt}}\)[/tex] = 0
Therefore, the rate at which the distance between the cars is increasing 2 hours later is 0 mi/h.

The probability that a die will land on 5 is 0.1.
The statement "If a probability is unlikely, then the probability is less than 1/2" is true in this context.
To determine the probabilities, we need to calculate the relative frequency of each outcome by dividing the frequency of that outcome by the total number of rolls (20 in this case).
The frequency table provided is as follows:
Value of Die | Frequency
1 | 5
2 | 3
3 | 4
4 | 5
5 | 2
6 | 1
To find the probability that a die will land on 5, we divide the frequency of 5 by the total number of rolls:
Probability of landing on 5 = Frequency of 5 / Total number of rolls
= 2 / 20
= 0.1
Therefore, the probability that a die will land on 5 is 0.1.
Similarly, to find the probability of landing on 1:
Probability of landing on 1 = Frequency of 1 / Total number of rolls
= 5 / 20
= 0.25
Thus, the probability that a die will land on 1 is 0.25.
Now, if a probability is unlikely, it means the probability is less than 1/2. In this case, we need to compare the probabilities to 0.5.
Since the probability of landing on 1 is 0.25, which is less than 0.5, we can conclude that the probability of landing on 1 is unlikely.
Therefore, the statement "If a probability is unlikely, then the probability is less than 1/2" is true in this context.

How to find the length in a secant?If two secant segments are drawn to a circle from an exterior point, then the product of the measures of one secant segment and its external secant segment is equal to the product of the measures of the other secant segment and its external secant segment.
Therefore, let's find the value of x using the secant intersection theorem as follows;
4(4+x + 2) = 5(5 + x - 1)
4(6 + x) = 5(4 + x)
24 + 4x = 20 + 5x
24 - 20 = 5x - 4x
x = 4
Therefore,
x = 4

Which two of the following are not characteristics of surveys?
A. The study involves one or more treatment groups and a control
group.
B. The study compares two or more treatments.
C. Statistical analysis is applied to the results of the study.
D. Data are gathered during the course of the study.
Answer: A and B are not characteristics of surveys.
Step-by-step explanation: A survey is a type of research method that involves collecting data from a sample of individuals or groups, usually by asking them questions or observing their behavior. Surveys can be used to describe, compare, or explain various aspects of a population or phenomenon of interest.
Some of the common characteristics of surveys are:
They use a predefined set of questions or items that are standardized and consistent for all respondents or participants.They use a sampling technique to select a representative subset of the population or target group that is relevant to the research question or objective.They use a mode of data collection that is suitable for the type and format of the questions or items, such as face-to-face interviews, telephone interviews, mail questionnaires, online surveys, etc.They use statistical analysis to summarize, describe, compare, or infer the results of the data collected from the sample to the population or target group.Some of the types of research methods that involve one or more treatment groups and a control group, and that compare two or more treatments, are:
Experiments: Experiments are research methods that involve manipulating one or more independent variables (the treatments) and measuring their effects on one or more dependent variables (the outcomes). Experiments aim to establish causal relationships between variables by controlling for other factors that may influence the results. Experiments usually involve random assignment of participants to different treatment groups and a control group that receives no treatment or a placebo.Quasi-experiments: Quasi-experiments are research methods that resemble experiments but lack some of the features of true experiments, such as random assignment or manipulation of variables. Quasi-experiments aim to estimate causal relationships between variables by using natural or existing variations in the independent variables (the treatments) and comparing their effects on the dependent variables (the outcomes). Quasi-experiments usually involve non-equivalent groups that differ in their exposure to the treatments or in other characteristics that may affect the results.Observational Studies: Observational studies are research methods that involve observing and measuring existing phenomena without manipulating any variables. Observational studies aim to describe, compare, or correlate variables by using natural or existing data sources. Observational studies usually involve different groups that are selected based on their exposure to the variables of interest or based on other criteria that may affect the results.Hope this helps, and have a great day! =)

Answer:
∠ G = 73° , ∠ H = 98°
Step-by-step explanation:
EFGH is a cyclic quadrilateral, its 4 vertices lie on the circle.
the opposite angles sum to 180°
A
∠ E + ∠ G = 180° , that is
11x + 8 + 8x + 1 = 180
19x + 9 = 180 ( subtract 9 from both sides )
19x = 171 ( divide both sides by 19 )
x = 9
Then
∠ G = 8x + 1 = 8(9) + 1 = 72 + 1 = 73°
B
∠ H + ∠ F = 180° , that is
6y - 4 + 5y - 3 = 180
11y - 7 = 180 ( add 7 to both sides )
11y = 187 ( divide both sides by 11 )
y = 17
Then
∠ H = 6y - 4 = 6(17) - 4 = 102 - 4 = 98°
Answer:
A) m∠G = 73°
B) m∠H = 98°
Step-by-step explanation:
The diagram shows a cyclic quadrilateral.
A cyclic quadrilateral is a four-sided shape drawn inside a circle, where every vertex touches the circle's circumference.
As the opposite angles in a cyclic quadrilateral add up to 180°, then:
m∠E + m∠G = 180°m∠H + m∠F = 180°We can use these equations to find the values of x and y.
m∠E + m∠G = 180°
(11x + 8)° + (8x + 1)° = 180°
11x + 8 + 8x + 1 = 180
19x + 9 = 180
19x + 9 - 9 = 180 - 9
19x = 171
19x ÷ 19 = 171 ÷ 19
x = 9
m∠H + m∠F = 180°
(6y - 4)° + (5y - 3)° = 180°
6y - 4 + 5y - 3 = 180
11y - 7 = 180
11y - 7 + 7 = 180 + 7
11y = 187
11y ÷ 11 = 187 ÷ 11
y = 17
Now we have found the values of x and y, substitute them back into the angle expressions to find m∠G and m∠H.
m∠G = (8x + 1)°
m∠G = (8(9) + 1)°
m∠G = (72 + 1)°
m∠G = 73°
m∠H = (6y - 4)°
m∠H = (6(17) - 4)°
m∠H = (102 - 4)°
m∠H = 98°
