Answer:
Depth = 14 ft Length = 20 ft width = 12 ft
Step-by-step explanation:
Given that an architect is designing a swimming pool
Let length = x
width = x-8
Height = x-6
Then volume of swimming pool = base area x height
base area = area of triangle = 
Volume = 
Solving we find that x=20
Verify:
Length = 20: Width = 12: and height = 14
Volume = 1/2 (20)(12)(14) = 1680 ft ^3
Answer:
circumference = pi x diameter
30x 3.14 = 94.2

Step-by-step explanation:
Answer:
The length of the rope = 8.94 meters
Step-by-step explanation:
∵ The flagpole is 8 meters high
∵ The hook is 4 meters from its base and the hook is in the ground
∵ The flagpole and the ground ⊥ to each other
By using Pythagoras theorem:
∴ The length of the rope = √(8² + 4²) = 5√5 = 8.94 meters
You would have to make the numbers have the same denominator. So you would have -15/20 + 4/20
Then you would have to put the sign of the higher number on it, So you would have -15/20 + 4/20 = -11/20
