The unit rate is 1:50. I did the math but I’m just guessing because you didn’t put any choices
SOLUTION:
Step 1:
In this question, we are given the following:
What is the midpoint of a line segment with the endpoints (-4,-3) and (7,-5)?
A. (-3.5, 1)
B. (1.5,-4)
C. (-4,1.5)
D. (1.-3.5)
Step 2:
The midpoint of a line segment with the endpoints (-4,-3) and (7,-5) is:

A:
Width of the deck =
units
Length of the deck =
units
So area of rectangular deck = Length * width
= 
Area = 
Area=
units square
As mentioned in part B, the area of the pool is
so the combined area of the deck and pool is
Area = area of rectangular deck + area of pool
=
unit square
B:
The area of only the deck is
unit square
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
Therefore, the diameter is 6 inches (THE THIRD OPTION)
