Answer:

Hours of television because it is the explanatory variable.

Step-by-step explanation:

For me, I am assuming the more time spent watching television would cause lower reading scores. I imagine this would be a bar graph, the vertical y-axis would be labeled the reading scores and the horizontal x-axis would be the amount of hours spent watching television. This is because when you graph, you move right then up to get to the unit, meaning the hours of television affect the reading scores. hope this helpss

Write the equation of a line that includes the point (22, 12) and
STatiana [176]

Let's start with y = 4x + b (since 4 is the slope);

We need to find what number should be put instead of b;

Then, let's see what needs to be done;

Plug in the y and x values from the coordinate (22,12) into y=4x+b;

12 = 4(22) + b

Solve;

12 = 88 + b

12 - 88 = b

b = -76

Remember the equation y = 4x + b? Put the -76 instead of b:

y = 4x + -76

or: y = 4x - 76

That is the equation.

To make it standard form, put x and y both in the left side, with x first then y:

-4x + y = -76

A rectangular prism has a length of 212 centimeters, a width of 212 centimeters, and a height of 5 centimeters. Justin has a sto
BlackZzzverrR [31]

Answer:

3.75\ cm^{3}  or  3\frac{3}{4}\ cm^{3}

Step-by-step explanation:

step 1

Find the volume of the rectangular prism

we know that

The volume of a rectangular prism is

V=LWH

In this problem we have

L=2\frac{1}{2}\ cm=\frac{2*2+1}{2}=\frac{5}{2}\ cm

W=2\frac{1}{2}\ cm=\frac{2*2+1}{2}=\frac{5}{2}\ cm

H=5\ cm

substitute in the formula

V=(\frac{5}{2})(\frac{5}{2})(5)=\frac{125}{4}=31.25\ cm^{3}

step 2

Find the difference between the volume of the prism and the volume of the storage container

35\ cm^{3}-31.25\ cm^{3}=3.75\ cm^{3}

3.75=3\frac{3}{4}\ cm^{3}
