Answer:
-1
Step-by-step explanation:
Answer:
ft
Step-by-step explanation:
We know that the height of the object and the height of the shadow it casts are proportional. Therefore, if we let the length of the tree be
, we can set up the following proportion to solve for it:
![\frac{5}{8}=\frac{x}{32}](https://tex.z-dn.net/?f=%5Cfrac%7B5%7D%7B8%7D%3D%5Cfrac%7Bx%7D%7B32%7D)
Solving for
, we get:
![\frac{5}{8}=\frac{x}{32}](https://tex.z-dn.net/?f=%5Cfrac%7B5%7D%7B8%7D%3D%5Cfrac%7Bx%7D%7B32%7D)
(Cross-Products Property)
(Simplify)
(Divide both sides of the equation by 8 to get rid of
's coefficient)
(Simplify)
Therefore, the tree is
ft tall. Hope this helps!
N divided by 3 equals 7
n/3 = 7
n=21
A. and D. are the only ones that has the value of x=3
