Answer:

57°

Step-by-step explanation:

Exterior Angle Theorem: An exterior angle of a triangle is equal to the sum of the opposite interior angles.

(9x+16) + (6x+15) = 136

15x + 31 = 136

15x = 105

x = 7

plug into (6x + 15)

6(7) + 15 = 42 + 15 = 57

$35,125 loan, a feat which took ten years of quarterly payments. The loan had an interest rate of 7.44%, compounded quarterly. I

Darya [45]

First find the amount of each payment:
$35,125 = P(\frac{(1+i)^{40} -1}{i (1+i)^{40}}) , i = \frac{.0744}{4} \\ \\ P = 1252.70$

The total cost will be 40 payments plus service charges.
$40*1252.70 + 5180.70 = 55,288.90$

The percentage is the service charge divided by total cost:
$X = \frac{5180.70}{ 55,288.90} = .0937 = 9.37\%$

In 1980, the average cost of a pack of cigarettes was $0.88. In 2000, the average cost was $5.31 per pack.

yan [13]

Answer:

The average rate of change of the cost of a pack is 22 cents per year.

Another name for the average rate of change is slope.

Step-by-step explanation:

The average rate of change of the cost of a pack ( $r$ ), in monetary units per year, is equal to the change in the average cost of a pack ( $\Delta c$ ), in monetary units, divided by the change in time ( $\Delta t$ ), in years. Then, the average rate of change is:

$r = \frac{\$\,5.31-\$\,0.88}{2000-1980}$

$r = \$\,0.22\,\frac{1}{yr}$

The average rate of change of the cost of a pack is 22 cents per year.

Another name for the average rate of change is slope.
