Answer: 120 ft
<u>Step-by-step explanation:</u>
The Ellipse equation is:
where
- (h, k) is the center
- "a" is the horizontal radius
- "b" is the vertical radius
- c is the distance from the center to the foci: |a² - b²| = c²
Given: horizontal diameter = 122 → horizontal radius = 61 = a
vertical diameter = 22 → vertical radius = 11 = b
Foci (c): 61² - 11² = c²
3721 - 121 = c²
3600 = c²
±60 = c
Let (h, k) = (0, 0)
Then the foci are located at -60 and +60.
The distance between them is 60 + 60 = 120
The subtrahend is 9 and the difference is 8 and the minuend is 17
Replace X with 3 and simplify. The answer you would get is 11.

Answer:
$88
Step-by-step explanation:
To find the increase of $80 by 10%, find 10% of $80 then add it by the original amount
10% of 80=80*0.1=$8
The original amount=$80
Total amount=$80+$8=$88
