1 answer:

3 0

He is attributed with defining that galaxies revolve, and was capable to determine the velocities at which they rotate. Slipher had discover that most galaxies presented a redshift in their spectrum, representing that they were all moving away from us in interstellar, or retreating (Slipher, 1915). By computing the magnitude of the redshift, he was capable to control the recessional velocity or the speediness at which matters were "flying." Slipher had made a clarification from his observations that put a new standpoint on the universe, and in reply, he established a standing ovation for his demonstration.

A homeowner estimates that it will take him 9 days to roof his house. A professional roofer estimates that he could roof the hou

Ulleksa [173]

Answer:

The time it will take to roof the house if the homeowner helps the roofer is 2.25 days.

Explanation:

The time it takes the homeowner to roof his house is, X = 9 days.

The time it takes the professional roofer to roof the house is, Y = 3 days.

Then if the the homeowner helps the roofer, the time it will take to roof the house is, X + Y.

The work done by the homeowner in 1 day is, $\frac{1}{X}=\frac{1}{9}$ .

The work done by the professional roofer in 1 day is, $\frac{1}{Y}=\frac{1}{3}$

The work done in 1 day if both the homeowner and the professional roofer work together is,

⇒ $Work\ done\ in\ day=(\frac{1}{X}+\frac{1}{Y})=(\frac{1}{9}+\frac{1}{3})=\frac{1+3}{9}=\frac{4}{9}$

Then the number of days it takes to roof the house if both the homeowner and the professional roofer work together, i.e. X + Y is,

⇒ $(X+Y)=\frac{1}{Work\ done\ in\ 1\ day}=\frac{1}{(\frac{4}{9}) } =\frac{9}{4} =2.25\ days$

Thus, the time it will take to roof the house if the homeowner helps the roofer is 2.25 days.
