Answer:
π
Step-by-step explanation:
the formula is V = πr2h
pie times radius to the second power times hight
The length of a rectangle is 12 inches more than its width. What is the width of the rectangle if the perimeter is 42 inches?
x best represents .
x + 12 best represents
profit=f(x)
so solve for f(x)=1000
1000=70n-400
add 400 to both sides
1400=70n
divide both sides by 70
20=n
20 students need to be enrolled to make a profit of 1000.00
Answer: 45%
Step-by-step explanation:
Converting the word problem into words, we have:
18= x/100*40
Solving for it, we get that x=45.
Step 1: Find common denominators
LCM of 2 and 4 = 4
2 3/4 - 1 2/4
Step 2: Subtract
2 - 1 = 1
3/4 - 2/4 = 1/4
Answer: 1 1/4
Hope this helps!! :)
