Carnival M charges an entrance fee of $5.00 and $0.50 per ticket for rides. Carnival P charges and entrance fee of $7.00 and $0.
Sergio039 [100]

The number of tickets that should be purchased for the cost of both carnival to be equal is 10 tickets.

Assume the number of tickets to be purchased is x.

The expression for the total cost at Carnival M is:

= Entrance fee + (price of tickets x number of tickets)

= 5 + 0.50x

The expression for the total cost at Carnival P is:

= 7 + 0.30x

To find the number of tickers, equate both expressions:

5 + 0.50x = 7 + 0.30x

0.50x - 0.30x = 7 - 5

0.20x = 2

x = 2 / 0.20

= 10 tickets

10 tickets will need to be bought to both Carnivals for the cost to be the same.

Answer:

  (b)  10.5 in

Step-by-step explanation:

The formula for the volume of a cone is ...

  V = 1/3πr²h . . . . . . for radius r and height h

Then the height is ...

  h = 3V/(πr²)

Your cone has a volume V = 199 in³ and radius r = 4.25 in, so the height is ...

  h = 3(199 in³)/(π(4.25 in)²) ≈ 10.52 in

The height of the cone is about 10.5 inches.
