An architect built a scale model of a shopping mall. On the model, a circular fountain is 20 20 inches tall and 22.5 22.5 inches in diameter. The actual fountain is to be 8 8 feet tall. What will be the diameter of the fountain? (A) 7.1 7.1 feet (B) 9 9 feet (C) 7 7 feet (D) 10.5 10.5 feet Explanation
Verified Step 1 1 of 2 Given a circular fountain is 20 i n c h e s inches tall and 22.5 inches in diameter. Writing above scale as fraction Height Diameter = 20 22.5
Diameter Height = 22.5 20
Now given the fact that actual fountain is 8 f e e t feet i.e 96 i n c h e s inches tall and let its diameter be x x i n c h e s inches, therefore 20 22.5 = 96 x
You can determine this by multiplying 52 by 50, because you get 50 dollars for 52 weeks, then add 500 to it, because you get 500 dollars at first. 52 times 50 is equal to 2600, and 2600 + 500 is equal to 3100. You will receive $3100 over the course of 52 weeks.
