I have been stuck on number 10 (this problem) for a while now. Can anyone help me with it and walk me through every step in orde

When you multiply a same number but with different powers, you can simply add the powers together. So, in your question, add the powers -1 and -7 together.
7^(-1) x 7^(-7) = 7^(-8)

When you divide a same number but with different powers, you subtract the power at the top with the power from the denominator. So, -8 - (-7) = -1.
7^(-8) / 7^(-7) = 7^(-1)

So your answer would be 7^(-1).
Hopefully my explanation was clear?

Mariulka [41]

Answer:

156.06 ft²

Step-by-step explanation:

The applicable formula for the area of the triangle is ...

Area = (1/2)bc·sin(A)

Filling in the given numbers, you have ...

Area = (1/2)(30 ft)(14 ft)·sin(48°) ≈ 156.06041335 ft²

The area of the triangle is about 156.06 square feet.
