1a) Some of the interior angles of a 15-gon must be 13 x 180=2340 degrees. Since it’s regular, the total is shared equally among the interior angles. 2340/15=156 degrees

Answer:

1a) 2340

1b) 120°

Step-by-step explanation:

1a) formula to find the sum of the interior angles is: (n-2) * 180

n = the number of sides

(15-2) * 180

(13) * 180 = 2340

2a) the formula to find the measure of one interior angle is:   \frac{(n-2) * 180}{n}

n = the number of sides

a hexagon has 6 sides

(6-2)*180

4 * 180 = 720

720 ÷ 6 = 120

Jess deposited $5,000 into an account that earns simple interest. After 9 years, Jess had earned $3,150 in interest. What was th
musickatia [10]

Answer:

The interest rate of Jess's account was 7%

Step-by-step explanation:

A = P * (1 + rt)

A = final amount

P = initial principal balance

r = annual interest rate

t = time (in years)

Replacing with the values we know:

A =  P * (1 + rt)

8,150 = 5,000 * (1 + r * 9)

8,150/5,000 = 1 + 9r

1.63 = 1 + 9r

1.63 - 1 = 9r

0.63 = 9r

r = 063/9

r = 0.07 = 7%

The interest rate of Jess's account was 7%

The half-life of aspirin is about 3 hours. If someone takes 700mg, how long will it take until less than 50mg is left in that pe
uranmaximum [27]
In 3 hours half of 700 would be 700/2=350

in 3 more hours, so 6 total, the half life would be 350/2 = 175

in 3 more hours, 9 total, the half life would be 175/2 = 87.5

in 3 more hours, 12 total, the live life would be 87.5 / 2 = 43.75

 so it would be 12 hours to have less than 50 mg
