What is an equivalent expression for s^-10 divided by s^3

s^-13

Step-by-step explanation:

you subtract when it is division

s^-10 / s^3

-10 - 3 = -13

s^-13

145.8 pounds

Step-by-step explanation:

So, if there is 9720 pounds total, and 98.5% of it must be pure paper, than 1 - .985 is how much can be impurities.

1-.985 = .015 or 1.5%

Now lets multiply .015 times 9720

.015(9720) = 145.8

The maximum weight of impurities is 145.8 pounds
