Answer:
a = 195 ; c = 615
Step-by-step explanation:
So, you want to start by forming your equations...
I will use 'c' for children and 'a' for adults for my variables
3a + 30 = c
(this is because of the info that 30 more tickets than 3 times the amount of children's were sold than adult)
then for equation 2:
3c + 5a = 2820
(this is because of the prices of the tickets and the total money raised)
Then, plug in the equation for c
Your equation should look like:
3(3a + 30) + 5a = 2820
You get:
(9a +90) + 5a = 2820
Then:
14a = 2730
So:
a = 195 adult tickets sold
Plug in a, to find c:
3 (195) + 30 = c
585 + 30 = c
c = 615 children tickets sold
The product of (x1)^2 is 20
2x20
1x40
4x10
5x8
All integers these multiply to 40
Given both the distance from the tree and the height of the tree, the angle of elevation can be obtained using the tangent formula, tangent theta = opposite side / adjacent side. In this case, opposite side = the tree's height and the adjacent side is the distance of Cisco to the tree. Therefore, the angle of elevation equals 40.03 degrees.
