I would use algebra to solve this:
let the amount of child ticket sold be x and the amount of adults ticket sold be 2x
so 2x•9.60+ x•6.30 = 969.00
19.2x+6.30x = 969.00
25.5 x =969.00
x=38
hence ans is 38
an alternative solution would be:
9.60×2 + 6.30 = 25.5
969.00÷25.5= 38
the methods are actually almost the same.
This is tricky, as your sentence can be interpreted in multiple ways. The sentence translates into one of the following expressions:

Answer:
C is correct. 3 cycles will complete in 0 to 2π
Step-by-step explanation:
We are given function y=sin 3x with interval
As we know the period of y=sin x is 2π
It means in 0 to 2π sin x complete one cycle.
But here we have y=sin(3x) So, period of this function should be different.
Here coefficient of x is 3.
So, In interval 0 to 2π. Total number of cycles would be 3.
Thus, 3 cycles will complete in 0 to 2π
Answer=5,12,13
Just plug all of these values into the pythagorean theorem. If they work, then they could represent a right triangle.
For example:
5²+12²=13²
25+144=169
169=169
