Answer:
8 child tickets and 4 adult tickets.
Step-by-step explanation:
8c + 11a = 108
8x + 11y = 108
Lets graph it.
When we graph, we find that there it crosses at 2 whole numbers: (8, 4).
So there were 8 child tickets and 4 adult tickets.
We can check our work by doing 8(8) + 4(11) = 108
We find that this is true, so our answer is correct.
Answer:
$625
Step-by-step explanation:
K(t)=10t+425
k(20)=10(20)+425
k(20)=200+425
k(20)=625
$625

Answer:
16 square feet
Step-by-step explanation:
First, let's find how long each side of the cube is.
The volume of a cube is found by this formula, where s is a side of the cube:
We can take the cube root of both sides:
Just flipping it:
We know our volume is 64 cubic feet. Let's put that into our equation as V:
The cubic root of 64 is 4, since 4 * 4 * 4 = 64
Thus, each side of our cube is 4 feet.
Now, the area of a side of our cube is found using this formula:
Since we know s, we can easily find the area A by squaring it:
Answer: 16 square feet
