John and Mary are using rolls of fabric to make a rectangular stage curtain for their class play. The rectangular piece of fabric on each roll measures 2.5 feet by 15 feet. If the area of the curtain is 200 square feet, what is the least number of rolls they need?

NEED THIS ASAP WITH WORK

The least number of rolls needed

= 5 rolls

Step-by-step explanation:

Area = length x width

A = l x w

A = 15 x 2.5

A = 37.5 ft²

If 37.5 ft² = 1 roll

What about 200 ft² = ?

= (200 x 1) ÷ 37.5

= 200 ÷ 37.5

= 5.33°

Least number of rolls. = 5 rolls

c. y = 1/4 x + 5

step-by-step explanation:

first, put the equation of the line on the graph into slope-intercept form

(y = mx + b):   y = -4x + 8

second, a perpendicular line has to have "an opposite/reciprocal slope" to the original slope. so, find the "m" value in your original equation (it's -4, right? )

original slope: m = -4   perpendicular slope: change the sign to its opposite and find the reciprocal ("flip" the number)

new slope is now positive (b/c the original slope was negative 4), and it's 1/4 (not the original slope of 4 or 4/1)

step-by-step explanation:

i'm pretty sure it would take 20 hours because it's half the men so you multiply the number of hours it takes by 2
