You lend $240 to your friend. He pays you back $30 in interest in one year. What interest
rate did you charge your friend?

12.50%

Step-by-step explanation: Lets use an equation find the the interest rate.

30 = p x 240

30/240 = p x 240/240

0.125 = p

Multiply 0.125 by 100 to get the interest rate. 0.125 x 100 = 12.5

12.5% = p

step-by-step explanation:

there is a formula i can give you:

it is r^2*n*sin(360/n) divided by 2 where r represents the "radius" and n is the number of sides.

plug them in:

(10sqrt(3))^2*6*sin(360/6) divided by 2

100*3*6*sin(60) divided by 2

900*sin(60)

900*sqrt(3)/2

450*sqrt(3)

approx is 779.4 cm^2

24/56=hx^7
