Answer:
Step-by-step explanation:
First you must find the number of cubic feet in the pool. (That's volume)
Formula
V = l*w*h
Givens
Solution
<em><u>Volume</u></em>
V = 38 * 22 * 8
V = 6688 cubic feet.
<em><u>Gallons</u></em>
1 cubic foot = 7.5 gallons
6688 ft^3 = x
<em><u>Proportion</u></em>
1/6688 = 7.5 / x Cross Multiply
x * 1 = 7.5 * 6688
x = 50160 gallons
Answer:
10,995.6 ft^3.
2300.3 gallons.
(both to the nearest tenth).
Step-by-step explanation:
Area of the surface of the river = area of the outer circle - area of the inner circle.
Radius of the outer circle = 30 *3 = 90 feet.
So the surface area of the river = π(90)^2 - π(85)^2
= 875π ft^2
Also the volume of the river = surface area * depth = 875π*4 = 3500π ft^3
= 10,995.6 ft^3.
Number of gallons of water it will hold = 10,995.6 / 4.78
= 2300.3 gallons.
Answer:
B:942$
Step-by-step explanation:
(pi*20^2)/2 is approximately 628.32
628.32*1.5=942.48
Answer:
Step-by-step explanation:
The amplitude (A) and the mean (M) temperature are given by:
The mean temperature, 45 degrees. occurs at midnight (t=0) and the frequency is f=24h. Therefore, the temperature D, in degrees, as a function of t, in hours, is:
Answer:
144
Step-by-step explanation:
Jane has 2 times as many books as Jill, so there are 3 parts. Two parts Jane and one part Jill. So, divide 216 by 3 and it's 72, which equals one part. Jane has two parts, so 72 x 2. Jane has 144 books.
