Answer:
100 or 150 units of the product.
Step-by-step explanation:
R = x(1000-4x)
What is the value of x if R = 60,000?
x(1000-4x) = 60000
-4x^2 + 1000x = 60000
x^2 - 250x = -15000
x^2 - 250x + 15000 = 0
Factorize:
(x-100)(x-150) = 0
x-100 = 0 V x-150 = 0
x = 100 V x = 150

Answer:
Step-by-step explanation:
The Westside recreation center built a new swimming pool that measures 20 ft by 15 ft. The pool is rectangular. The formula for determining the perimeter of a rectangle is expressed as
Perimeter = 2(length + width)
Therefore, perimeter of the pool would be
2(20 + 15) = 70 ft
The formula for determining the area of a rectangle is expressed as
Area = length × width
Therefore, area of the pool would be
20 × 15 = 300 ft^2
The formula for determining the volume of a rectangle is expressed as
Volume = length × width × height
Given depth = 6 feet
Therefore, volume of the pool would be
20 × 15 × 6 = 1800 ft^3
