Answer:
h = 9 feet.
Step-by-step explanation:
The height at the top of a roller coaster hill is 10 times the height h feet of the starting point. The height decreases 100 feet from the top to the bottom of the hill. The height at the bottom of the hill is -10 feet.
Therefore, there is a zero elevation point between the starting point at h height and the bottom of the hill which is at - 10 feet from the zero elevation point.
Now, the elevation of the top of the hill from the zero elevation point is (100 - 10) = 90 feet.
Therefore, 10h = 90
⇒ h = 9 feet. (Answer)

Answer:
is the total time taken to clean the house.
Step-by-step explanation:
Given that:
Betsy cleans 
of the house.
Time taken = 1 hour
To find:
Time taken to clean the whole house = ?
Solution:
We can use unitary method here to solve this problem.
We are given that of the house is cleaned in 1 hour.
We have to find that a total of 1 house will be cleaned in how much time.
(1 house because Betsy's house can be considered as a single unit).
To find this we will divide 1 hour with .
Now, Let us solve this mathematically:
of the house is cleaned in = 1 hour
1 of the house will be cleaned in = 1 hour divided by
So, the <em>answer </em>is:
is the total time taken to clean the house.
The solution is in the attached below
Circumference=31.4yd
