The zeros of a function are when y = 0, so set the right side of the equation equal to 0. Then factor; the right side becomes (3x-2)(3x+4). Set both of those parentheses equal to zero to find the zeros, or roots, of the equation. 
x = 2/3, x = -4/3

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.
