The Venice flagpole is 27 feet tall.
Myrna Loy's outstretched fingertip is 18 feet above the ground.
If a 24 foot long wire is stretched between the top of the flagpole and Myrna's fingertip, how far is Myrna's fingertip from the top of the flagpole?
Draw a diagram, then solve for the missing side. Round your answer to the nearest tenth.
Answer:
Step-by-step explanation:
I probalby am not reading the question correctly, but it seems be be asking the distance between Myrna's fingertip (18 feet above the ground!) and the top of the 27' foot flagploe. We are not told where Myrna is standing, nor how she got her fingertip 18 feet high. Since we are asked for a diagram, I did the best I could, not knowing much about Myrna other than she must be tall. On her behalf, I assumed Myrna was directly under the flagpoe. As shown in the attached diagram, her fingertip is 9 feet below the top of the flagpole.
If the 24 foot wire is stretched all the way (i.e., it takes 24 feet to reach Myrna's fingertip), then she is not standing directly below the flagpole. But this isn't clear in the problem. In any event, if the question is how far she is from the very top of the flagpole from where she is standing, it would be the 24 foot lenght of the wire connecting her to the top of the flagpole. If the question just wants the vertical distance, then it is 9 feet.
If she is standing away from the flagpole, then a diagram would appear roughly as follows:
x
x s
x 27' s 24'
x s
x ----------z-------------- y
x y
x y 18'
x ----------z-------------- y
flagpole Myrna
The distance z is calculated using the Pythagorean Theorem in the top triangle. The left side is (27'-18') or 9'. The hypotenuse is 24'.
z^2 + 9^2 = 24^2
z = 22.2 feet.

The cube root of 1 is 1. So, t = 1.
The total mass of a box and some oranges was 25kg. The total mass of the same box and some apples was 11kg. The mass of the oranges was 3 times the mass of apples
From The total mass of orange and box, the mass of oranges are 2kg and the mass of empty box is 23kg.
Let's use "o" to represent the mass of one orange and "a" to represent the mass of one apple.
We can set up two equations based on the information given:
Box + Oranges = 25 kg (equation 1)
Box + Apples = 11 kg (equation 2)
Oranges = 3 x Apples (equation 3)
We can substitute equation 3 into equation 1 to eliminate "oranges":
Box + 3a = 25 kg
We can substitute equation 3 into equation 2 to eliminate "oranges" again:
Box + a = 11/3 kg
Now we have two equations with two unknowns. We can solve for "Box" and "a" using either substitution or elimination. For example, we can multiply the second equation by 3 and subtract it from the first equation:
Box + 3a = 25
3(Box + a = 11)
-2Box + 2a = 2
Simplifying, we get:
Box - a = -1
We can add this equation to the second equation to get:
2Box = 11 - 1 = 10
So, Box = 5 kg.
Now we can substitute this value back into equation 2 to find "a":
5 + a = 11/3
a = 2/3 kg
Finally, we can use equation 3 to find the mass of the oranges:
Oranges = 3 x Apples = 3 x (2/3) = 2 kg.
Therefore, the mass of the oranges is 2 kg.
The mass of the empty box is the difference between the total mass of the box and the fruit and the mass of the fruit:
Mass of box = Total mass - Mass of fruit
From equation 1, we know that the total mass of the box and the oranges is 25 kg. From part a, we know that the mass of the oranges is 2 kg. Therefore:
Mass of box = 25 kg - 2 kg = 23 kg.
So, the mass of the empty box is 23 kg.

How much is in that can?
A machine that fills beverage cans is supposed to put 12 ounces of beverage in each can. Following are the amounts measured in a simple random sample of eight cans. 11. 96 12. 10 12. 04 12. 13 11. 98 12. 05 11. 91 12. 03
B: If appropriate, perform a hypothesis test to determine whether the mean volume differs from 12 ounces. Use the a = 0. 05 level of significance. What do you conclude?
The calculated test statistic (t = -0.527) is not less than -1.894 or greater than 1.894.
A hypothesis test can be performed to determine whether the mean volume of beverage in the cans differs from 12 ounces using the following steps:
(1)State the null hypothesis and the alternative hypothesis.
The null hypothesis is that the mean volume of beverage in the cans is equal to 12 ounces (μ = 12). The alternative hypothesis is that the mean volume of beverage in the cans is not equal to 12 ounces (μ ≠ 12).
(2)Select a level of significance (α).
In this case, the level of significance is α = 0.05.
(3)Calculate the sample mean and standard deviation.
The sample mean can be calculated as:
mean = (11.96 + 12.10 + 12.04 + 12.13 + 11.98 + 12.05 + 11.91 + 12.03) / 8 = 12.04375
The sample standard deviation can be calculated as:
[tex]s=\sqrt((11.96 - 12.04375)^2 + (12.10 - 12.04375)^2 + (12.04 - 12.04375)^2 + (12.13 - 12.04375)^2 + (11.98 - 12.04375)^2 + (12.05 - 12.04375)^2 + (11.91 - 12.04375)^2 + (12.03 - 12.04375)^2) / (8 - 1))[/tex] [tex]s=0.277764079[/tex]
(4)Calculate the test statistic.
The test statistic can be calculated as:
t = (mean - 12) / (s / sqrt(8))
(5)Determine the critical value(s) from the t-distribution table with 7 degrees of freedom (8 - 1).
At a significance level of 0.05 and 7 degrees of freedom, the critical value from the t-distribution table is approximately ±1.894.
(6)Compare the test statistic to the critical value(s).
If the test statistic is less than -1.894 or greater than 1.894, then the null hypothesis can be rejected. Otherwise, the null hypothesis cannot be rejected.
(7)Conclude the hypothesis test.
In this case, the calculated test statistic (t = -0.527) is not less than -1.894 or greater than 1.894. Therefore, we cannot reject the null hypothesis. This means that there is not enough evidence to conclude that the mean volume of beverage in the cans is different from 12 ounces.

A piece of wood is cut into 3 pieces A, B and C, in the ratio 2 : 3:5. If C
is longer than B by 8 cm, find the length of the stick.
Answer:
18 cm
Step-by-step explanation:
Let's assume that the length of the stick is x cm.
Then, the lengths of pieces A, B and C would be 2x/10 cm, 3x/10 cm, and 5x/10 cm respectively.
Since C is longer than B by 8 cm, the length of C is 3x/10 + 8 cm, and the length of B is 3x/10 cm.
Therefore, the total length of the stick would be:
x = 2x/10 + 3x/10 + (3x/10 + 8)
x = 10x/10 + 8
x = 10 + 8
x = 18 cm
So, the length of the stick is 18 cm.
Answer: 20 cm
Step-by-step explanation:
create an equation.
2x : 3x : 5x
We are also told C is longer than B by 8 cm. So,
A : x : x+8
If 5x = x+8, solve for this: 4x = 8 so x =2.
Now, we can plug back in the original values.
2(2) + 3(2) + 5(2) = 20.
the stick is 20 centimeters long.

Two years ago, Rita was 3 times as old as Cheryl. In 3 years, Rita will be twice as old as Cheryl. How old are the girls now?
The current age of Rita is 17 years and Cheryl is 7 years respectively, according to mentioned data.
Let us assume Rita's present age be x and Cheryl's age be y.
Rita's age two years ago = 3 × Cheryl's age two years ago
x - 2 = 3 (y - 2) - equation 1
Rita's age after three years = 3 × Cheryl's age after three years
x + 3 = 2 (y + 3) - equation 2
Solving equation 1
x - 2 = 3y - 6
x = 3y - 6 + 2
x = 3y - 4
Solving equation 2
x + 3 = 2y + 6
x = 2y + 6 - 3
x = 2y + 3
Keep the value of x from equation 2 in equation 1
2y + 3 = 3y - 4
Rearranging the equation
3y - 2y = 3 + 4
y = 7
Keep the value of y in equation x = 2y + 3
x = 2×7 + 3
x = 14 + 3
x = 17

So, you need to have a list of primes handy:
2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47, 53, 59, 61, 67, 71, 73, 79, 83, 89, 97, ...
Now, take your number and try to divide it by the first prime, 2.
54 = 27 * 2
That worked. Note down the 2 and repeat with the result. You find 27 cannot be divided by 2 again, but it can be divided by 3 (the next prime in the list):
27 = 9 * 3
Note down the 3 and repeat:
9 = 3 * 3
Note down a 3 again.
So you have
54 = 2*3*3*3 = 2 * 3³
You can continue this until the result is a prime number itself. Then you are done.
point a has coordinates (-4,2) point a is translated to the point with coordinates (-1,-3) find as a column vector the vector that describes this translation
Answer:
To solve it, you need to use vectors. Let me show you how.
To find the vector that describes the translation, we need to subtract the coordinates of point A from the coordinates of the translated point. Let the vector be v. Then we have:
v = (-1, -3) - (-4, 2)
v = (-1 + 4, -3 - 2)
v = (3, -5)
To write this vector as a column vector, we write it vertically with square brackets. So we have:
v = [3
-5]
Therefore, the vector that describes the translation is [3
-5].

Yes, measures of variability are used to describe the extent to which scores in a distribution differ from one another.
Measures of variability include the range, variance, and standard deviation, and they give us a sense of how spread out the scores in a distribution are. These measures help us understand the variability or dispersion of the data and how far the individual scores in a distribution deviate from the mean or other measures of central tendency.
Measures of central tendency, such as the mean, median, and mode, describe the central or typical value of a set of scores. They provide a summary of the data and a single value that represents the center of the distribution.
The decisions regarding graph size, shape, and style are usually based on the type of data being presented and the message being conveyed. A histogram, for example, may be used to visually display the distribution of a set of scores, and the size, shape, and style of the graph can be adjusted to highlight important features of the data.

The properties of midpoints and rectangles to show that a quadrilateral with vertices at the midpoints of the sides of a rectangle is a rhombus.
In this problem, we will prove that a quadrilateral with vertices at the midpoints of the sides of a rectangle is a rhombus. This is an important result in geometry and is often used in solving more complex problems.
Let us consider a rectangle ABCD with sides AB, BC, CD, and DA. Let P, Q, R, and S be the midpoints of the sides AB, BC, CD, and DA, respectively.
We need to prove that PQRS is a rhombus, which means we need to show that all sides of PQRS are equal.
First, we can observe that PQ and SR are parallel to AD, and QR and PS are parallel to AB. This is because P and S are midpoints of AB and AD, and Q and R are midpoints of BC and CD, respectively. Therefore, PQ and SR are both half the length of AD, and QR and PS are both half the length of AB.
Next, we can use the fact that the opposite sides of a rectangle are equal. This means that AD = BC and AB = CD. Therefore, PQ and SR have the same length, as they are both half of AD. Similarly, QR and PS have the same length, as they are both half of AB.
Thus, we have shown that all sides of PQRS are equal, which means that PQRS is a rhombus.

If the difference between the water temperature and the room temperature is halved every 5 minutes, then the water temperature in degrees fahrenheit, after 15 minutes 86 f
If a cup is boiling water (212 f) is placed to cool in a room whose temperature remains constant at 68 f. suppose the difference between the water temperature and the room temperature is halved every 5 minutes .
Temperature can be measured in degree celsius, degree fahrenheit and kelvin. so here the temperature measured in degree fahrenheit
Initially the difference between water and room temperature is,
212 - 68 = 144f
For every 5 minutes the difference of water and room temperature is halved,
After 5 minutes the difference is, 144/2 = 72 f
After 10 minutes the difference is, 72/2 = 36 f
After 15 minutes the difference is, 36/2 = 18 f
So the water temperature in degrees fahrenheit, after 15 minutes will be the sum of room temperature and difference between the temperatures of water and room after 15 minutes and it is given as, 18 f + 68 f = 86 f
Therefore, the water temperature in degrees fahrenheit, after 15 minutes is 86 f.

Answer:
Step-by-step explanation:
To solve the system of equations:
9x - 2y = 4 ...(1)
3x + 8y = 12 ...(2)
We can use elimination method by adding or subtracting the equations in a way that one variable is eliminated.
Here are the possible ways to solve the system:
A) Multiply the first equation by 4, then add the equations.
Multiplying the first equation by 4 gives:
36x - 8y = 16
Adding the resulting equation to the second equation gives:
36x - 8y + 3x + 8y = 16 + 12
Simplifying the equation:
39x = 28
x = 28/39
Substituting x in equation (1) gives:
9(28/39) - 2y = 4
Solving for y gives:
y = -155/78
Therefore, the solution is (x,y) = (28/39, -155/78).
B) Multiply the second equation by 3, then add the equations.
Multiplying the second equation by 3 gives:
9x + 24y = 36
Adding the resulting equation to the first equation gives:
9x - 2y + 9x + 24y = 4 + 36
Simplifying the equation:
18x + 22y = 40
Dividing the equation by 2 gives:
9x + 11y = 20
Substituting 9x from equation (2) gives:
3x + 8y = 12
Solving for x gives:
x = (12 - 8y)/3
Substituting x in equation (3) gives:
9[(12-8y)/3] + 11y = 20
Solving for y gives:
y = 16/39
Substituting y in equation (2) gives:
3x + 8(16/39) = 12
Solving for x gives:
x = 28/39
Therefore, the solution is (x,y) = (28/39, 16/39).
C) Multiply the first equation by 3, then add the equations.
Multiplying the first equation by 3 gives:
27x - 6y = 12
Adding the resulting equation to the second equation gives:
27x - 6y + 3x + 8y = 12 + 12
Simplifying the equation:
30x = 24
x = 4/5
Substituting x in equation (1) gives:
9(4/5) - 2y = 4
Solving for y gives:
y = -23/10
Therefore, the solution is (x,y) = (4/5, -23/10).
D) Multiply the second equation by 3, then subtract the equations.
Multiplying the second equation by 3 gives:
9x + 24y = 36
Subtracting the second equation from the first equation gives:
6x - 26y = -8
Solving for x gives:
x = (26y - 8)/6
Substituting x in equation (2) gives:
3[(26y-8)/6] + 8y = 12
Solving for y gives:
y = 16/39
Substituting y in equation (1) gives:
9x - 2(16/39) = 4
Solving for x gives:
x = 28/39
Therefore, the solution is (x,y) = (28/39, 16/39).

What is an inequality symbol?A mathematical sign for comparing two values or expressions is an inequality symbol. Inequality symbols include: (less than), > (greater than), (less than or equal to), and (greater than or equal to). Inequalities can be used to represent connections between two or more variables, for as 5 10 indicating that 5 is less than 10. Inequalities can also be used to define mathematical equations or to describe connections between variables. The equation x + 2 7 can, for example, be used to represent the relationship between x and 7, or to communicate that the value of x must be less than 5 for the equation to be true.
In the given question,
2/3x + 2y < -1/3x + 1
⇒ 2/3x + 2y - (-1/3x + 1) < 0
