Your friend borrows $100 from you and promises to pay you back $109 in 8 months. What annual percentage rate (A.P.R.) are you ch

NNADVOKAT [17]

Answer:

$12.0\%=0.12$

Step-by-step explanation:

We have been given that your friend borrows $100 from you and promises to pay you back $109 in 8 months.

We will use simple interest formula to solve our given problem.

$A=P(1+rt)$ , where,

A = Amount after t years,

P = Principal amount,

r = Annual interest rate in decimal form,

t = Time in years.

Convert 8 months to year:

$\frac{8}{12}\text{ year}=\frac{2}{3}\text{ year}$

$108=100(1+r*\frac{2}{3})$

$108=100+r*\frac{2}{3}\times 100$

$108-100+r*\frac{200}{3}$

$108-100=100-100+r*\frac{200}{3}$

$8=r*\frac{200}{3}$

$8\times \frac{3}{200}=r*\frac{200}{3}\times \frac{3}{200}$

$\frac{24}{200}=r$

$r=\frac{24}{200}$

$r=0.12$

Convert to percent:

$0.12\times 100\%=12\%$

Therefore, you are charging 12% APR to you friend.

What is the area of one trapezoidal face of the figure?

Arturiano [62]

The area of a trapezoid, A, is the average of the lengths of the bases (B and b) multiplied by the height, h.

$A = \dfrac{(B + b)h}{2}$

$A = \dfrac{(3~in. + 1~in.) \times 1~in.}{2}$

$A = \dfrac{4~in. \times 1~in.}{2}$

$A = \dfrac{4~in.^2}{2}$

$A = 2~in.^2$
