Answer:
Denominator = 80
Step-by-step explanation:
Given:
The denominator is 16 greater than the numerator.
If the fraction is equivalent to 80 percent,
Question asked:
What is the denominator of the fraction ?
Solution:
Let numerator be ![x](https://tex.z-dn.net/?f=x)
Then the denominator =
(given)
As the fraction is equivalent to 80%,
![= 80\%](https://tex.z-dn.net/?f=%3D%2080%5C%25)
![\frac{x}{x+16} = \frac{80}{100} \\](https://tex.z-dn.net/?f=%5Cfrac%7Bx%7D%7Bx%2B16%7D%20%3D%20%5Cfrac%7B80%7D%7B100%7D%20%5C%5C)
By cross multiplication,
![100\times x = 80(x+16)\\100x = 80x + 1280\\](https://tex.z-dn.net/?f=100%5Ctimes%20x%20%3D%2080%28x%2B16%29%5C%5C100x%20%3D%2080x%20%2B%201280%5C%5C)
By subtracting both side by ![80x](https://tex.z-dn.net/?f=80x)
![100x - 80 x = 1280\\20x = 1280](https://tex.z-dn.net/?f=100x%20-%2080%20x%20%3D%201280%5C%5C20x%20%3D%201280)
By dividing both side by 20
![x = 64](https://tex.z-dn.net/?f=x%20%3D%2064)
Thus, numerator =
= 64
Then the denominator =
= 64 + 16 =80
Let x represent the answer.
7 + x = (43+x) / 3
3(7+x) = 43+x
21+3x = 43+x
2x = 22
x = 11
The answer is 11

Answer:
A=πr(r+(√h^2+r^2))
Square root line continues at the top of h^2 through r^2. r is radius and h is height for this problem.
Now substitute numbers for the variables.
A=π8(8+(√7^2+8^2))
Now solve.
The rest I will leave up to you.
