Answer: 9 games of golf.
Step-by-step explanation:
Because its $4 for clubs and $24 per game (without the membership) it would be $28 per time. If you keep multiplying 28 times a number until its greater than 224, you would get 9.
Answer:
around 40%
Step-by-step explanation:
This is a proportion question.
882 x
____ = ____
1,460 100
First, do 882 x 100 and get 88,200.
Then divide 88,200 by 1,460 to get around 60%.
Then 100-60= 40%.
Might be wrong but I'm pretty sure this is the answering method.
1. 3y to the power of 25-50y
2. (5x-3y) to the power of 10
3. x to the power of 6x-25
4. x to the power of x - 28
There maybe another step here but I think you just simplify them to lowest terms.
Answer:
dc/dx = 0 when x = 20. hence fence is 20×40
Step-by-step explanation:
Given data:
Rectangular Area = 800 ft^2
three side material cost = $5 per ft
fourth side material cost is $15 per ft
let expensive side is x and other dimension assume to be y
Then cost is c
c = 5(x+ 2y) + 15 x
xy = 800, so y = 800/x
c =5(x+ 1600/x^2) + 15x
for minimum when dc/dx = 0
(2x-40)(2x+40) = 0
x = 20
dc/dx = 0 when x = 20. hence fence is 20×40
