Answer: D 1800 degrees

Step-by-step explanation:

The sum of the interior angles can calculated by using the formula 180(n-2) where n is the number of sides of the shape. Plug 12 in for n and you'll get 1800 degrees which is the sum of all the interior angles in the polygon. Hope this helps :D

maw [93]

Answer:

Step-by-step explanation:

I'm goig to assume that the formula we need here is the following:

$A(t)=P(1+\frac{r}{n})^{(n)(t)$

where A(t) is the amount in the account after the compounding is done, n is the number of times per year the compounding occurs, r is the rate in decimal form, and t is the time in years. Filling in accordingly,

$A(t)=90000(1+\frac{.06}{2})^{(2)(5)}$ and simplifying a bit,
