Answer:
( 6(x)² + 12(x) - 90 ) ft³
Explanation:
- <u>deep end water</u>: 2(x)² + 12(x) + 10
- <u>shallow end water</u>: 4(x)² - 100
addition problem: 2(x)² + 12(x) + 10 + 4(x)² - 100
total volume of water:
- 2(x)² + 12(x) + 10 + 4(x)² - 100
- 2(x)² + 4(x)² + 12(x) + 10 - 100
Because 16/5 and 48/15 are equivalent fractions
Let x = number of adult tickets
Let 2x = number of student tickets.
So, x + 2x = 336
3x = 336
x = 112
They sold 112 adult tickets.
Edit to reflect comments:
3^-1=1/3
4^-1=1/4
Flip the fraction over basically i.e. 4/1---->1/4
62 words per minute. You would divide 8 from 496 since you need to find out how many words he can type in a minute. Your answer is 62 words per minute.
