Find the rate if a principal of $1100 earned 1089 interest in 12 years

5.9%

Step-by-step explanation:

I'm going to assume that interest is convertable every year and it is  compound interest

So we know that

Interest Earned=PV(1+i)^n-PV

plug in what we know to get

1089=1100(1+i)^12-1100

Solve for x and get

x=.059=5.9%

b. 24 mm

step-by-step explanation:

use the pythagorean theorem.

a^2 + b^2 = c^2

a^2 + 7^2 = 25^2

a^2 + 49 = 625

a^2 = 576

a = 24

answer: b. 24 mm
