Answer:

<u>The correct answer is B. 40 mph</u>

Step-by-step explanation:

1. Let's review the information provided to us to answer the question correctly:

Distance (d) the car traveled = 120 miles

Time (t) of the travel = 3 hours

2. What is the average rate of speed?

Rate of speed (r) = Distance (d) the car traveled/Time (t) of the travel

Replacing with the real values, we have:

Rate of speed (r) = 120/3 miles per hour

Rate of speed (r) = 40 miles per hour

<u>The correct answer is B. 40 mph</u>

A container is shaped like a cylinder with half spheres on each end. The cylinder has a length of 30 centimeters and a radius is
Crank

The cubic centimeter one container can hold is 2,878.33 cm³.

<h3>What is the  cubic centimeter one container can hold ?</h3>

In order to determine the  cubic centimeter one container can hold, the volume of the container has to be determined.

Volume of the container = volume of the cylinder + (2 x volume of the hemisphere)

Volume of the cylinder = πr²h

Where:

  • π = 3.14
  • r = radius
  • h = height

3.14 x 5² x 30 = 2355 cm³

Volume of a hemisphere = (2/3) x π x r³

2 x (2/3 x 3.14 x 5³) = 523.33 cm³

Volume of the container =  523.33 cm³ + 2355 cm³ = 2,878.33 cm³

Which graph represents the linear function y = x 3/4– 4?
ahrayia [7]

Answer:

The graph in the attached figure

Step-by-step explanation:

we have

y=\frac{3}{4}x-4

This is a linear equation (the graph is a line)

To identify the graph find out the intercepts

<u><em>Find out the y-intercept</em></u>

The y-intercept is the value of y when the value of x is equal to zero

For x=0

y=\frac{3}{4}(0)-4=-4

The y-intercept is the point (0,-4)

<u><em>Find out the x-intercept</em></u>

The x-intercept is the value of x when the value of y is equal to zero

For y=0

0=\frac{3}{4}x-4

\frac{3}{4}x=4

x=16/3=5.33

The x-intercept is the point (5.33,0)

therefore

The graph in the attached figure
