Answer: 21
Step-by-step explanation:
Using functions, the input is x, the output is y.
<u>Break down the problem:</u>
The output (y) is (equals) one-fourth (1/4) of the input (x)
y equals 1/4 of x
In mathematical expression, the equation then becomes 7 - 2n = 5
The next procedure is to find the unknown.
1. 7 - 2n = 5
2. -2n = 5 - 7
3. -2n = -2
4. n = -2/-2
5. n = 1
Check:
Substitute n = 1
7 - 2 (1) = 5
7-2 = 5
5=5

Answer:
The volume of the inflated beach ball is 13734in³
Step-by-step explanation:
We know that the formula to calculate the volume of a sphere is
v = 3/4 * π * r³
π = 3.14
r = 18in
we replace the values and calculate the volume of a sphere
v = 3/4 * 3.14 * (18in)³
v = 3/4 * 3.14 * (5832in³)
v = 13734.36 in³
the nearest whole number
13734in³
