A grain casts a shadow of 40 feet while a nearby fence post casts a shadow of 2 feet. The fence ost is 5 feet high. How tall is the grain silo?

The grain silo is 16 feet tall

Step-by-step explanation:

You can rewrite the question with 5/2=40/x and the height of the silo is x. we need to get 5 to 40 and to do that we times by 8 b/c 5*8=40 and what we do with the top number we do with the bottom number, 2*8=16.
