Answer:
60
Step-by-step explanation:
x = (1/2)(172 - 52)
x = (1/2)(120)
x = 60
I'm going to refer to the length of the pool as L.
2x + 2L = perimeter.
The width of pool multiplied by two added to the length of the pool multiplied by two equals to the perimeter.
<u>Given</u>:
The given equations are
and 
We need to determine the pair of numbers that is a member to the system of equations.
<u>Pair of numbers:</u>
The pair of numbers can be determined by solving the system of equations.
Let us use the substitution method to solve the equations.
Substituting
in the equation
, we have;




Thus, the value of x is 1.
Substituting x = 1 in the equation
, we get;



Thus, the value of y is 7.
Hence, the pair of numbers that is a member of both the equations are (1,7)
Since all the volume of the liquid will be contained by all 30 spheres then,
30 V = 3392.92
where V is the volume of each sphere
Solving for V
V = 113.0973
The formula for the volume of the sphere is:
V = (4/3) π r³
Since diameter, D = 2r
V = (4/3) π (D/2)³
V = (4/3) π (1/8) D³
V = (1/6) π D³
Since V = 113.0937
113.0937 = (1/6) π D³
D = 6
<span>Therefore, the diameter is 6 inches </span>
