a) 2.7 ft
b)8.8 ft
c)13.2 ft
d)132 ft
A 6-ft fence casts a shadow of 10 ft. At the same time a tree casts a shadow of 22 ft. How tall is the tree?
6/10 = x/22
6 = x
---- ----
10 22
132 = 10x
x = 13.2
c) 13.2ft
Reply:D. 13.2
Reply:Proportions: the shadow is a little more that twice as long so the tree must be a little more that twice as tall.
Reply:its C; 22 divided by 10 is 2.2 and 2.2 times 6 is 13.2
Reply:duh the answer is c
Reply:13.2 feet. The 6 foot fence is 3/5 of its shadow, so logically the tree's height would be 3/5 of its shadow.
