Jill drew a picture that was 9 inches by 12 inches. She needs to scale the picture so that it is 39 ft by 52 ft for a mural on the school cafeteria wall. What is the scale factor for the dilation? Draw
a picture and show your work.

4

Step-by-step explanation:

Divide 39 by 9 to get 4

39÷9=4

check the picture below.

well, the angle at the vertex d is clearly not a right-angle, let's check for the one at the vertex f which does look like,   however if it's indeed, that means ef is perpendicular to df, in which case their slopes will be negative reciprocal of each other.

so the negative reciprocal of the slope of ef is 1, however the slope of df is not 1, is 1/2, so nope, they're not perpendicular lines.

4+n=5

step-by-step explanation:

this is because the four is four hours and the n represents the 1 extra hour over the weekend.

b= i'm srry i don't know that one.

4+n=5 n=1 because if vernon plays 5 hours a week then 4+1=5 hours.

hope this : )
