Answer: 7.5 is the height
Step-by-step explanation: use the formula for volume it is given that the base are is 12 pi which means your radius is solved for you. V = 90 so just divide 90 pi with 12 pi = 7.5 ,
Answer:
$289,169.84 (to the nearest cent)
Step-by-step explanation:
Compound interest is based on the principal amount and the interest that accumulates on it in every period.
Compound Interest = P (1 + r)^n
where P = principal amount, r = annual interest rate (as a decimal), n = term, in years
So for this problem:
P = 185000
r = 1.4 ÷ 100 = 0.015
n = 30
Therefore,
Compound Interest = P (1 + r)^n
= 185000 x (1 + 0.015)^30
= 185000 x (1.015)^30
= 289169.8408...
= $289,169.84 (to the nearest cent)
Answer: $4.95
Step-by-step explanation:
divide 4.40 by 8 to get unit price:
4.40/8 = 0.55
Add 0.55 to 4.40 to get the cost of 9 oranges
0.55 + 4.40 = $4.95
The area of the triangle could be determined by multiplying the length and the width. Since, we are given the area and the length, to find the width, you divide the area by the length:
w = A ÷ l
w = (x2 - 2x - 15) ÷ (x+3)
What do you have to multiply to (x+3) to yield x2 - 2x - 15? That would be x - 5. Since the sum of -5 and 3 = -2 (middle term) and the their product is -15 (last term).
Hence, the width is (x-5).
