Answer:
The number of child tickets = 39
Step-by-step explanation:
It is given that,child admission is $5.20 and adult admission is $8.60
Total sales = $868.00
<u>To find the number of child tickets</u>
Le 'x' be the number of children then number of adults = 2x
(x * 5.20) + (2x * 8.60) = 868
5.2x + 17.2x = 868
22.4x = 868
x = 868/22.4
= 38.75 ≈ 39
Therefore the number of child tickets = 39
Equation of a circle: (x - h)² + (y - k)² = r²
(h, k) = center
r = radius
We have the following values:
(-5, 7) = center (h, k)
3 = radius (r)
~Substitute with the given values
(x - (-5))² + (y - (7))² = (3)²
~Simplify
(x + 5)² + (y - 7)² = 9
Answer: (x + 5)² + (y - 7)² = 9
Best of Luck!
