I need help with this question plz
pashok25 [27]

First you need to distribute the exponent into the terms for the first parenthesis.

(-3x²y³)³ = (-3)³ * (x²)³ * (y³)³

= -27 *x⁶ *y⁹

= -27x⁶y⁹

Then you multiply -27x⁶y⁹ by x²y.

You just need to add the exponents of x and y:

-27x⁶⁺²y⁹⁺¹

= -27x⁸y¹⁰

Mary sews at a rate of 60 inches per hour. How many feet does she sew in a minute?
makvit [3.9K]

Answer:

B. 0.083 rounded to the nearest thousandth.

Step-by-step explanation:

It is known that 12 inches = 1 foot and

60 minutes = 1 hour

Since we want to covert from inches per hour to feet per minute, then we would change 60 inches to feet in 1 hour 2 minutes in divide.

If 12 inches = 1 foot, then

60 inches = 60/12 = 5 feet

Therefore, the number of feet that she sews in a minute is

5/60 = 0.083 feet per minute

She sews 0.083 feet per minute.

This is the full explanation for this question.
