Answer:

<h2><em><u>B. (-1/2)^-3</u></em></h2>

Step-by-step explanation:

B is the answer. This is because you have to calculate (-1/2)^-3 on a calculator. When I did that calculation, I got -8.

(-1/2)^-3      =    (-2)^3 = -2*-2*-2 = 4 * -2 =<em><u> -8</u></em>

Hope this helped,

Help for number 4 part a and part b
djyliett [7]
Part A:  7/10 because .7 represents 70/100 of a whole, or 7/10.

Part B: I think 1 and 89/100 because 89/100 represents that fraction

These are my answers, so I may be wrong.

Hope I helped, and good luck!
