One roofer can put a new roof on a house three times faster than another. Working together they can roof a house in 5 days. How many days would it take the faster roofer to put a new roof on a house working alone? Round the answer to the nearest tenth.

  6.7 days

Step-by-step explanation:

If t is the time the faster roofer takes, then the slower one takes 3t. Their combined rates in roofs per day are ...

  1/t + 1/(3t) = 1/5

  4/(3t) = 1/5 . . . . . . combine terms

  t = 5(4/3) = 20/3 ≈ 6.7 . . . . multiply by 5t

The faster roofer working alone can roof a house in about 6.7 days.

typically if you want , you would actually put questions here for us to you. but hey, that's just me. maybe someone will magically answer the questions for you without knowing what they are.

the answer for this question is : 360°

step-by-step explanation:

we have been given a triangle   we need to tell which one of these is a triangle below to map onto itself.

360° rotation is the complete rotation which eventually leads to the same figure which is given.

the correct will be, that is 360° that will cause the triangle below to map onto itself.
