The percentage change of a ratio of two variables is approximately the percentage change in the numerator _____ the percentage c
olchik [2.2K]

Answer:

"The percentage change of a ratio of two variables is approximately the percentage change in the numerator <u>minus</u> the percentage change in the denominator."

Step-by-step explanation:

The percent change in a number is determined by dividing the difference between the new number and original number by the original number and multiplying the result by 100.

Suppose the original ratio of two numbers is: \frac{25}{100}.

And the new ratio is: \frac{75}{100}

The percent change is:

Change\%=\frac{75-25}{100}\times100=\frac{50}{100}\times100=50\%

Thus, the complete statement is:

"The percentage change of a ratio of two variables is approximately the percentage change in the numerator <u>minus</u> the percentage change in the denominator."

____ [38]

The formula for finding the volume of a rectangular prism (the cargo area of the truck is the shape of a rectangle in 3D; a rectangular prism) is V = (l)(w)(h); where <em>l</em> = length, <em>w</em> = width, and <em>h</em> = height.

First, substitute the known values into the equation:

l = 8.5

w = 6

h = 10.5

V = (8.5)(6)(10.5)

<em>(Note: .5 = 1/2)</em>

Now, all we need to do is simplify:

V = 535.5 ft³ OR 535 1/2 ft³

<em>(Note: ft</em><em>³</em><em> is the condensed form of cubic feet)</em>

You can pick whichever form your test directs you to use. They are both the same value though.

Hope this helps!
