The rectangles shown are similar. the dimensions are given in inches. what is the width of the smaller rectangle?

12.5 inches

Step-by-step explanation:

We can use proportions to solve this.  The first triangle side over the same side of the 2nd triangle.

50 inches      25 inches

=

25 inches         x inches

Using cross products

50x = 25*25

Divide each side by 50

50x/50 = 25*25/50

x =12.5

$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)
