Answer:
x = 26
Step-by-step explanation:
Since s║t and r is a transversal, consecutive interior angles add to 180
⇒ 2(x + 15) + (3x + 20) = 180
⇒ 2x + 30 + 3x + 20 = 180
⇒ 5x + 50 = 180
⇒ 5x = 180 - 50
⇒ 5x = 130
⇒ x = 130/5
⇒ x = 26
Answer:
x=26
Step-by-step explanation:
Given:
s || t
2(x+15) + (3x+20) = 180°
Since the sum of co interior angle is 180°
Opening bracket
2x + 30 + 3x + 20 =180
Solving like terms
5x+50= 180
subtracting both side by 50
5x=180-50
5x = 130
dividing both side by 5.
[tex]\tt x=\frac{130}{5}[/tex]
x = 26
Therefore value of x is 26.

which one of the following general term of sequence is arithmetic?
The options that represent arithmetic sequences are A) 2n - 1, C) 3n + 4, and D) 5n - 2.
To determine which of the given general terms represents an arithmetic sequence, we need to check if the difference between consecutive terms is constant. Let's evaluate each option:
A) 2n - 1
To find the difference between consecutive terms, we subtract the general term for the (n+1)th position from the general term for the nth position:
[(2(n+1)) - 1] - (2n - 1) = 2n + 2 - 1 - 2n + 1 = 2
Since the difference between consecutive terms is 2, option A) 2n - 1 represents an arithmetic sequence with a common difference of 2.
B) n^2 + 3
Let's calculate the difference between consecutive terms:
[(n+1)^2 + 3] - (n^2 + 3) = n^2 + 2n + 1 + 3 - n^2 - 3 = 2n + 1
The difference between consecutive terms is 2n + 1, which is not a constant value. Therefore, option B) n^2 + 3 does not represent an arithmetic sequence.
C) 3n + 4
Calculating the difference between consecutive terms:
[(3(n+1)) + 4] - (3n + 4) = 3n + 3 + 4 - 3n - 4 = 3
The difference between consecutive terms is 3, which is a constant value. Therefore, option C) 3n + 4 represents an arithmetic sequence with a common difference of 3.
D) 5n - 2
Finding the difference between consecutive terms:
[(5(n+1)) - 2] - (5n - 2) = 5n + 5 - 2 - 5n + 2 = 3
The difference between consecutive terms is 3, which is a constant value. Therefore, option D) 5n - 2 represents an arithmetic sequence with a common difference of 3.

58, 61, 71, 77, 91, 100, 105, 102, 95, 82, 66, 57
If a value of 120.5° is added to the data, how does the mean change and by how much?
The mean stays at 83.5°.
The mean increases by 3.1°.
The mean increases by 3.5°.
The means stays at 80.4°.
Answer:
The mean increases by 3.5°.
Step-by-step explanation:
To determine how the mean changes when a value of 120.5° is added to the data, we need to recalculate the mean before and after the addition.
Given the average high temperatures:
58, 61, 71, 77, 91, 100, 105, 102, 95, 82, 66, 57
To find the original mean, we sum up all the temperatures and divide by the number of data points:
(58 + 61 + 71 + 77 + 91 + 100 + 105 + 102 + 95 + 82 + 66 + 57) / 12 = 904 / 12 = 75.33°
Now, let's add the value of 120.5° to the data:
58, 61, 71, 77, 91, 100, 105, 102, 95, 82, 66, 57, 120.5
To find the new mean, we sum up all the temperatures (including the added value) and divide by the number of data points:
(58 + 61 + 71 + 77 + 91 + 100 + 105 + 102 + 95 + 82 + 66 + 57 + 120.5) / 13 = 1025.5 / 13 ≈ 78.88°
The mean has increased from 75.33° to 78.88°.
Therefore, the mean increases by approximately 3.55° (rounded to the nearest tenth).
The correct answer is: The mean increases by 3.5°.
Answer:
The mean increases by 3.5°.

F5
The simplified boolean expression for F5 is F5 = P OR (NOT R). In this expression, P represents one boolean variable, and (NOT R) represents the negation of another boolean variable R. The OR operator combines the two variables, resulting in the final boolean expression F5.
To simplify the boolean expression F5 = (P AND Q) OR (R AND NOT P), we can apply Boolean algebra rules to reduce it to its simplest form.
Step 1: Apply De Morgan's laws
NOT (R AND NOT P) can be simplified as (NOT R) OR P.
Step 2: Distributive property
F5 = (P AND Q) OR ((NOT R) OR P)
Step 3: Apply associative property
F5 = (P AND Q) OR (P OR (NOT R))
Step 4: Apply absorption law
F5 = P OR (P OR (NOT R))
Step 5: Apply idempotent law
F5 = P OR (NOT R)
By simplifying the expression, we have reduced it to its simplest form while preserving its logical meaning. The simplified expression can be used to analyze and evaluate logical circuits or systems where the variables P and R are used.
Remember, boolean algebra allows us to manipulate and simplify complex logical expressions by applying various rules and properties. These simplifications help in understanding and analyzing logical operations in digital systems and circuits.

Drake is correct, and Selena is incorrect in this scenario.Option D.
Selena's Work:
Selena substituted the values for the variables r = -1 and s = -2 directly into the expression before simplifying. She then simplified the expression and evaluated it.
However, this approach is incorrect because the order of operations requires simplification before substitution. Selena should have simplified the expression first and then substituted the values of r and s.
Drake's Work:
Drake followed the correct order of operations. He simplified the expression first and then substituted the values of r = -1 and s = -2. By simplifying the expression, Drake obtained (-1/-2), which simplifies to 1/2. After substituting the values, Drake evaluated the expression correctly and arrived at the final result of 1/2.
Since Drake followed the correct order of operations and obtained the correct result, he is the one who is correct. Selena's mistake was in not simplifying the expression before substituting the values for r and s.
In mathematical operations, it is important to follow the order of operations (PEMDAS/BODMAS) to ensure accurate results. The correct order is to simplify the expression first, and then substitute the given values for the variables. So Option D is correct.

What is a piecewise function?A piecewise function comprises of two or more functions, which are defined based on specified intervals of the input variable.
The possible piecewise function that is represented by h(x), obtained from a similar question on the site can be presented as follows;
[tex]h(x) \begin{cases} \frac{1}{4}\cdot x-4, & \text{ } x\leq0 \\\frac{1}{3}\cdot x - 3, & \text{ } 0 < x \leq 3 \\\frac{1}{2}\cdot x-2, & \text{ } x\geq4\end{cases}[/tex]
Therefore, at x ≤ 0, the y-intercept is -4, for h(x) = (1/4)·x - 4, which corresponds to the second graph.
The range for h(x) at 0 < x ≤ 3 is; h(0) = (1/3)×0 - 3 < h(x) ≤ (1/3)×3 - 3, which can be expressed as; (-3, -2], also corresponding to the second graph
The value of x-intercept of h(x) in the interval x ≥ 4 can be found from the equation; h(x) = (1/2)·x - 2 = 0
(1/2)·x = 2
x = 2 × 2 = 4

There are 50 animals in a shelter. Sixty percent of the animals are dogs. Which equation can be used to find the number of dogs in the shelter?
StartFraction 60 divided by 2 Over 100 divided by 2 EndFraction = StartFraction 30 Over 50 EndFraction
StartFraction 100 times 2 Over 50 times 2 EndFraction = StartFraction 200 Over 100 EndFraction
StartFraction 50 divided by 1 Over 60 divided by 1 EndFraction = StartFraction 50 Over 60 EndFraction
StartFraction 60 times 2 Over 50 times 2 EndFraction = StartFraction 120 Over 100 EndFraction
The correct Option is A. Equation that can be used to find the number of dogs in the shelter is StartFraction 60 divided by 2 Over 100 divided by 2 EndFraction = StartFraction 30 Over 50 EndFraction.
In order to do that, we first need to determine the number of dogs in the shelter.
We can do that by multiplying the total number of animals by 60% (0.60):60% of 50 = (60/100) × 50 = 30
Therefore, there are 30 dogs in the shelter.
Now, we can look at the answer choices to see which equation can be used to find the number of dogs in the shelter.
A. (60/2 ÷ 100/2) = 30/50This equation simplifies to (30 ÷ 50) = 0.6, which is the decimal equivalent of 60%. T
his equation is correct.
B. (100 × 2 ÷ 50 × 2) = 200/100
This equation simplifies to 1, which is not the correct answer.
C. (50 ÷ 1 ÷ 60 ÷ 1) = 50/60
This equation simplifies to 5/6, which is not the correct answer.
D. (60 × 2 ÷ 50 × 2) = 120/100
This equation simplifies to 6/5, which is not the correct answer.
Therefore, the equation that can be used to find the number of dogs in the shelter is A. (60/2 ÷ 100/2) = 30/50.

The polygons that can be regarded as similar polygons are A and D.
What are similar polygons?Similar polygons are those whose sizes may vary but whose shapes are the same. To put it another way, they have proportional sides and corresponding angles that are equivalent. The geometric likeness or resemblance between them is referred to as being "similar".
Similar polygons have corresponding angles with the same measurements. For instance, if a right angle exists in one polygon, another polygon with a comparable angle will likewise have a right angle. Similar to this, if an angle in one polygon is 60 degrees, the comparable angle in a related polygon will also be 60 degrees.
