Answer:
That day 51 child tikets were sold
Step-by-step explanation:
To do this problem we have to make 2 equations, one that represents the number of entries and the other that represents the money
x = child tickets
y = adult tickets
x + y = 132
x * $5.20 + y * $9.00 = $994.20
First we have to solve for the x in the first equation
x + y = 132
x = 132 - y
Now we replace the x with (132 - y) in the second equation
x * $5.20 + y * $9.00 = $994.20
(132 - y) * 5.20 + y * 9.00 = 994.20
686.4 - 5.2y + 9y = 994.2
-5.2y + 9y = 994.2 - 686.4
3.8y = 307.8
y = 307.8/3.8
y = 81
We replace y with its value in the first equation
x = 132 - y
x = 132 - 81
x = 51

Answer: 31.5ft²
Step-by-step explanation:
For any given triangle with two adjacent sides and an opposing angle, the area is determined by the formula:
1/2 * length A * length B * sin of angle of opposing side.
That is, if lenght A=x, length B= y and opposing angle is given as Z, then the area of such triangle becomes:
Area = 1/2 *x*y*sin Z
For the given triangle, x = 11feet, y = 10feet, Z=35°
Area= 1/2 * 11 * 10 * sin 35
Area = 31.5469ft²
Rounding up to the nearest tenth,
Area = 31.5ft²
