The correct answer is: D) $31,752.78
Explanation:
The formula for compound interest is:
where A is the total amount, p is the principal invested, r is the interest rate as a decimal number, n is the number of times per year the interest is compounded, and t is the number of years.
The principal in this problem is 25,000; the interest rate is 3% = 3/100 = 0.03; the number of times the interest is compounded is 4; and the number of years is 8:
R = 12 inches, the radius of the wheel.
The circumference of the wheel is
2πr = 2π(12) = 24π inches.
WHen the wheel makes 15 revolutions, the car will travel 15 times the circumference, which is
15*(24π) = 360π inches = 1131 inches.
Answer: 1131 inches
Answer:
7 x 10^3
Step-by-step explanation:
7 x 10 x 10 x 10
This is a proportion problem. Let the monument me x feet tall.
40/x=5/6
Cross multiply:
240=5x
x=48 ft.
So the monument is 48 ft tall,
The variable x is equal to 3
