Answer:
A. x = 7
B. x = -3
Step-by-step explanation:
A. 5/x = 30/42
5/x = 5/7
5 = 5/7 x
5= 5x/7
5 x 7 = 5x
35 = 5x
35/5 = x
7 = x
x = 7
B. x/8 = -12/32
x/8 = -3/8
x = - 3/8 x 8
x = - 24/8
x = -3

Answer: 7 feets
Step-by-step explanation:
A 7 feet stop sign creates a shadow that is 2 feet long. At the same time a utility pole creates a shadow that is 2 feet long. How tall is the utility pole.
Length of shadow created by 7 feet stop sign = 2 feets
Length of shadow created by utility pole = 2 feets
Length of utility pole =?
Since the length of shadow created by a body is dependent on the height of the body and the position of the sun.
Since the length of shadow are similar = 2 feets
The height of the utility pole and the sign post would be the same.
Hence, height of utility pole will be 7 feets
