A dilation with a scale factor of 2 is applied to the three line segments shown. The resulting images are P′Q′¯¯¯¯¯¯¯ , A′B′¯¯¯¯
Alex
Since the scale factor of the dilation is 2, you would multiply each of the pre-image line segments' lengths by 2.

therefore,
P'Q'=4cm
A'B'=3cm
M'N'=6cm

Hope this helps you out!

It takes Ms. Campbell 5 times as long as it takes Ms. Dorsey to paint a room. If Ms. Dorsey
Aliun [14]

Answer:

Dorsey = 4.8 hours

Campbell = 24 hours

Step-by-step explanation:

It takes "x" hours for Dorsey

So, it will take 5 times more for Campbell, so

It takes "5x" hours for Campbell

Rate is inverse of time, so rates are:

Dorsey: 1/x

Campbell: 1/5x

We know Rate * Time = Work

When together, it takes 4 hours to finish a work, so we can write:

(\frac{1}{x}+\frac{1}{5x})4=1

Solving for x, we get the time of Dorsey:

(\frac{1}{x}+\frac{1}{5x})4=1\\(\frac{1}{x}+\frac{1}{5x})=\frac{1}{4}\\\frac{5+1}{5x}=\frac{1}{4}\\\frac{6}{5x}=\frac{1}{4}\\5x=24\\x=4.8

Dorsey takes 4.8 hours alone

Campbell takes 4.8 * 5 = 24 hours alone
