Nan rode the roller coaster 8 times which was twice as many times as she rode the ferris wheel

Answers

I'm assuming that you're looking for the number of times Nan rode the Ferris Wheel. The question says that 8 times is twice as many times as the Ferris Wheel, so you would divide 8 by 2 to get 4. Nan rode the Ferris Wheel 4 times.

What is Proportion?

In general, the term "proportion" refers to a part, share, or amount that is compared to a total.

According to the concept of proportion, tworatios are in proportion when they are equal.

A mathematical comparison of two numbers is called a proportion. According to proportion, two sets of provided numbers are said to be directly proportional to one another if they increase or decrease in the same ratio. "::" or "=" are symbols used to indicate proportions.

Given:

length of Shadow Height

8 20

12 x

18 y

z 6.5

Using proportion

8/12 = 12 / x

8x = 144

x= 144/8

x= 18

and, 8/ 20 = 18/ y

8y = 360

y = 360/ 8

y = 45

and, 8/20 = z/6.5

130 = 8z

z= 16.25

Hence, the length of fence shadow is 16.25 feet.
