3. the triangle will be dilated by a scale factor of 2.5.
(a) what is the length of each of the sides after the dilation?
(b) draw the new image and label it .

Part a) The length of each of the sides after the dilation is

Part b) The graph in the attached figure

Step-by-step explanation:

Part a) What is the length of each of the sides after the dilation?

In this problem we have that the scale factor is 2.5

The scale factor is greater than 1

so

The dilation is an enlargement

To find the length of each of the sides after the dilation, multiply the original length by the scale factor

so

Part b) Draw the new image and label it

using a graphing tool

see the attached figure

$53.50

step-by-step explanation:

you have to subtract the amount of money chuck earned ($72.50) by the cost of the gas for the mower ($11.25) and the new string for the trimmer he bought ($7.75).

72.50-11.25=61.25

and then subtract $61.25 by the second thing he bought (the new string for the trimmer)

61.25-7.75=53.5

so in total it's $53.50 (53 dollars and 50 cents)
