Question 239209: Please help me. I'm having trouble with this problem.
At a given time of day, the ratio of the height of an oject to the length of its shadow is the same for all oject. If a 5ft post casta a shadow of 1.2ft, find the length of the shadow for a 17ft post.

You can put this solution on YOUR website!
5%2F1.2+=+17%2Fx
Multiply both sides by 1.2x
5x+=+1.2%2A17
5x+=+20.4
x+=+4.08
The length of the shadow is 4.08 ft
