Answer:
<u>Aaron played 4 games and went on 2 rides at the carnival.</u>
Step-by-step explanation:
1. Let's review the information provided to us to answer the question correctly:
Cost of each game = US$ 2.75
Cost of each ride = US$ 4.75
Total spent by Aaron at the carnival = US$ 20.50
Number of rides = x
Number of games = 2x (the number of games he played is twice the number of rides he went on)
2. Determine the number of games Aaron played and the number of rides Aaron went on.
For determine the number of games and the number of rides, we will use the following equation:
2.75 (2x) + 4.75x = 20.50
5.5x + 4.75x = 20.50
10.25x = 20.50
x = 20.50/10.25
x = 2 ⇒ 2x = 4
<u>Aaron played 4 games and went on 2 rides at the carnival.</u>

Answer:
The distance travelled by ball is 98 units before it again reaches the same height from which it was thrown.
Step-by-step explanation:
The given parabolic equation is

Where, h is height of ball after covering x distance horizontally.
Put x=0, to find initial height of the ball.



Put y=5.5 in the given equation and find the values of x at which the height of ball is 5.5.




Take square root both sides.



The height of ball is 5.5 at x=0 and x=98.
Therefore distance travelled by ball is 98 units before it again reaches the same height from which it was thrown.
