Answer:
x = 5
Step-by-step explanation:
150+25x= 55x
-25x -25x

The diameter of circle B is 50 cm.
Step-by-step explanation:
Given,
The circumference of circle A = 314.159 ft
Diameter of Circle B is half of the diameter of circle A.
Let, the radius of circle A is r
To find the diameter of circle B
Formula
Circumference of a circle of radius r = 2πr
According to the problem,
2πr = 314.159
or, r = 
= 50 (approx)
So,
The diameter of circle A = 2×50 cm = 100 cm
The diameter of circle B = 50 cm.
Answer:84
Step-by-step explanation:Using proportions, it is found that the height of the lighthouse is of 84 ft.
This question is solved by proportions, using a rule of three.
For a height of 5.25 feet, the shadow is of 8 feet. What is the height when the shadow is of 128 feet?
The rule of three is:
5.25 feet - 8 feet
x feet - 128 feet
Applying cross multiplication:
The height of the lighthouse is of 84 ft.
