Answer:
To find the constant of proportionality from the coordinates of
one point on the graph are as follows :-
1.) Find two easy points.
2.) Start with the leftmost point and count how many squares you need to up to get to your second point.
3.) Count how many squares you need to go to the right.
4.) Simplify, and you've found your constant of proportionality.
We will have to use proportions:

Cross multiplying we get

Now divide:

Solve to tenths place we get

The woman casts a 36.6 ft long shadow.
The formula for triangle area is b•h/ 1/2. so you would do 12•5=60. then divide that by 2 to get 30
<span>$8,000 x 0.13 = $1040
</span>$8,000 + $1040 = <span>$9,040
answer: </span>$9,040
34/4=8.5
8.5x5=42.5
The answer is $42.50
