Answer:

x = 5

Step-by-step explanation:

The equation of a line is given by :

y=2x+2.5

Where

y is cost and x is number of tickets

Put y = $12.5 in the above equation

So,

12.5=2x+2.5

10 = 2x

x = 5

So, he can purchase 5 tickets.

Answer:

$298

Step-by-step explanation:

Profit = Income - Cost

2 tires for 35 each, so total cost is 2*35=70.  Sold for 65 each, so income is 2*65=130. Profit is 130 - 70 = $60.

3 rims for 75 each, so total cost is 3*75=225. Sold 136 each, so income is 3*136=408. Profit is 408 - 225 = $183.

5 headlight covers for 4 each, so total cost is 5*4=20. Sold for 15 each, so income is 5*15=75. Profit is 75 - 20 = $55.

Total profit = 60 + 183 + 55 = $298

Find the altitude of a cylinder with with a radius of 9 and a surface area of approximately 791.68 units2.
Vika [28.1K]

In this question , it is given that we have a cylinder with with a radius of 9 and a surface area of approximately 791.68 units square.

The formula of surface area of cylinder is

A= 2 \pi r^2 + 2 \pi r h

Substituting the values of A and r, we will get

791.68 = 2* \pi * 9^2  + 2 * \pi * 9*h
\\
791.68 = 162 \pi + 18 \pi h
\\
791.68 -162 \pi = 18 \pi h
\\
h = \frac{791.68 -162 \pi}{18 \pi}
\\
h =5 units

So the height of the cylinder is 5 units .
