Perfect pipes charges $120 plus $40 an
hour to make plumbing repairs. no leaks
here charges $50 plus $60 an hour. for
how many hours is perfect pipes less
expensive than no leaks here?

Hey!

Prefect Pipes: 120 + 40 = $160 (y-intercept)

No Leaks Here: 50 + 60 = $110 (y-intercept)

Hour #1:

Prefect Pipes: 160 + 40 = $200

No Leaks Here: 110 + 60 = $170

Hour #2:

Prefect Pipes: 200 + 40 = $240

No Leaks Here: 170 + 60 = $230

Hour #3:

Prefect Pipes: 240 + 40 = $280

No Leaks Here: 230 + 60 = $290

$280 < $290

After 3 hours Perfect Pipes is less expensive than No Leaks Here!

Hope This Helped! Good Luck!

d 25 pi/6

step-by-step explanation:

the diameter is 10 inches

the radius is 1/2 of the diameter or 5 inches

the area of the circle is

a = pi r^2

  = pi 5^2

  = 25 pi

the slice is 60 degrees of the entire circle.

60 degrees out of 360   60/360 = 1/6

the area of the slice is 1/6 of the circle

a slice = 1/6 a circle

a slice = 1/6 * 25 pi

wait nvm i know the correct answer now its 100%   81 square feet
