Answer: Calculate the volume of each individual figure and add them.

Step-by-step explanation:

1. A composite figure is formed by two or more figures.

2. Then, to calculate the volume of the composite figure you must calculate the volume of each individual figure and then you must add all the volumes obtained.

3. For example, if a composite figure has a cylinder and a cone, the volume of the composite figure will be the sum of the volume of cylinder and the volume of the cone:

$V=V{(cylinder)}+V{(cone)}$

Sample Response: First, each three-dimensional shape that makes the composite figure needs to be identified. Apply the formulas for each shape to determine its volume. Finally, find the sum of the shape’s volumes.

will brought 3 college textbooks one cost 32 on 45 and one cost 39 what is the average price of his books ? choose the statement

777dan777 [17]

To find the average, add the cost of each book to get a total cost, then divide the total cost by the number of books purchased.

Total cost: 32 + 45 + 39 = 116

Average cost: 116 / 3 = 38.67

Ms. Hernandez gave her students a math test

emmainna [20.7K]

Answer:

85-86%

Step-by-step explanation:

Make it an equation

You want to find the percent out of a hundred, so 42 is 100 since it is all of the questions and 36 is the unknown percent X

36/42 = X/100

36 X

42 100

Cross multiply

Do math and solve for X

36 x 100 = 42 x X

3600=42X

X=85.71

the point slope form of the equation of a line that passes through (8,4) and (0,2) is y-4=1/4(×-8) what is the slope intercept f

marissa [1.9K]

Answer:

$\large\boxed{y=\dfrac{1}{4}x+2}$

Step-by-step explanation:

The slope-intercept form of the equation of a line:

$y=mx+b$

m - slope

b - y-intercept → (0, b)

The point-slope form of the equation of a line:

$y-y_1=m(x-x_1)$

m - slope

(x₁, y₁) - point

We have the equation of a line:

$y-4=\dfrac{1}{4}(x-8)\to m=\dfrac{1}{4}$

and the point (0, 2) → b = 2.

Substitute:

$y=\dfrac{1}{4}x+2$

Three potential employees took an aptitude test. Each person took a different version of the test. The scores are reported below

gavmur [86]

Answer:

Tobias did best on the aptitude test.

Step-by-step explanation:

The formula for calculating a z-score is is z = (x-μ)/σ, where x is the raw score, μ is the population mean, and σ is the population standard deviation.

For Emilio

Emilio got a score of 76; this version has a mean of 70.6 and a standard deviation of 9.

z = (x-μ)/σ

z = 76 - 70.6/9

z = 0.6

For Alissa

Alissa got a score of 298.8; this version has a mean of 282 and a standard deviation of 24.

z = (x-μ)/σ

z = 298.8 - 282/24

z = 0.7

For Tobias

Tobias got a score of 8.04; this version has a mean of 7.2 and a standard deviation of 0.4.

z = (x-μ)/σ

z = 8.04 - 7.2/0.4

z = 2.1

Looking at the calculated z score above, we can see that Tobias did better on his aptitude test because he had a higher z score compared to Emilio and Alissa.
