Explanation:
Let’s take kids as x and adults as y
According to the question,
5x + 2y = 25 (1)
3x + 1y = 14 (2)
Let’s multiply (2) with 2 so take we can solve the equations
5x + 2y = 25
6x + 2y = 28
(-) (-) (-)
___________
-1x = = -3
x = 3
Substituting to get y
3x + 1y = 14
3(3) + y = 14
y = 14-9
y = 5
Answer:
Therefore, each child’s skate rental (x) costs $3 and each adults’s skate rental (y) costs $5

Answer:
72π
Step-by-step explanation:
The computation of the volume of the cone is shown below:
Here The radius of the base is one of the legs, therefore it is 6.
And, The height of the cone represent the other leg, therefore it is also 6.
Now as we know that
The volume of the cone is
= 1 ÷ 3 πr^2h
= 1 ÷ 3π 6^2 6
= π × 36 × 2
= 72π
