It takes 40 minutes for 8 people to paint 4 walls.
How many minutes does it take 10 people to paint 7 walls?
minutes

56 minutes

Explanation: it will take 1/4 of the time to paint one wall. So it will take 10 minutes for 8 people to paint one wall. So the number of minutes it will take for one person to paint 7 walls is 80 x 7 =560 and because there is ten people 560/10=56.

the length of o'p' is .

step-by-step explanation:

it is given that the quadrilateral m'n'o'p' is the image of quadrilateral mnop after dilation.

the center of dilation is origin and the scale factor is 1.5.

in dilation the image and preimge are similar figures. it means the sides of image and preimage are proportional.

the scale factor is defined as

the scale factor is 1.5.

multiply both sides by op.

note: if the value of op is given, then multiply the value of op with 1.5 to get the length of side o'p'.

therefore length of o'p' is .
