Answer:

Hi there!

The correct answer to this question is: The <u>side length</u> of the square base is 18 inches and the <u>height</u> of the pyramid is 9 inches.

Step-by-step explanation:

The equation to find the volume of a square pyramid is V= (b^2)(h/3)

we are given the volume to be 972 inches cubed, additionally we know that the base of the square is x inches, the height is x/2

then we plug in and we get 972= (x^2)(x/2/3)

then you simplify to 972 = x^3 / 6 then you multiply six on both sides and  you get x^3 = 5832

cube root on both sides and you get x = 18 that means the base is 18 inches and the height is x/2 then you plug 18 in and you get the height to be 9 inches.

A factory makes 450 pies every day.
Gemiola [76]
Step by step:

Each day it takes a sample of 15 pies - on Monday he needed 4:

4/15 = x/450 (450 being the total for each day)

4 x 450 = 1800
1800 divided by 15 = 120

120 is the amount of pies that were made on Monday

Suppose you charge $4.50/h for baby-sitting. How much will you earn baby-sitting for 3 1/2 hours?
Sergeu [11.5K]

Answer:

You will earn $15.75, $13.50, or $18 depending on how you are getting paid

Step-by-step explanation:

If you are getting paid a flat rate not by the hour, then simply multiply $3.50 by 3.5 to get $15.75

If you are getting paid by the hour, and only by full hours, the you get $3.50 for the first, second, and third hour, but not for the fourth hour because it has only been a half hour, so only $13.50.

If you are getting paid for each hour that you start, then you get $3.50 for four hours, or $18.00 total

If f(x)=b^x and g(x)=\log_bx,

Then fog=b^{\log_bx}=x and gof=\log_bbx=x
