It would be C. Because PEMDAS. Division goes first in this equation. So it’d be 15 divided by 3 plus 6

Remember the laws of exponents:

$\frac{a^n}{a^m}=a^{n-m}$

Then:

$\begin{gathered} \frac{3^{100}}{3^{99}}=3^{100-99} \\ =3^1 \\ =3 \end{gathered}$

Therefore:

$\frac{3^{100}}{3^{99}}=3$

Which problem could be solved with the expression 4*(4+2)

Rina8888 [55]

The answer is A.

He ran for six (6) miles every day. 4 in the morning and 2 at night = 6 per day.

He did this for four (4) days. The way to figure this would be to go 6 * 4. This equals 24 miles.

Go back a few steps (punny!).

So days multiplied by how many miles he ran a day which is calculated by miles in morning added to miles at night.

days*(miles per morning + miles per night)

days=4
miles per morning=4
miles per night = 2

4 * (4+2)

Calculating this out....

4 * (4+2)

(4+2 = 6)

4 * 6 = 24.

So A is the answer.

Answer:

10.5 cm^2

Step-by-step explanation:

Since we have two sides and the angle between those sides, we can use the alternative area formula:

$A=\frac{1}{2}ab\sin(C)$
