Stacey is selling tickets to the school play. the tickets are $6 for adults and $4 for children. she sells twice as many adult tickets as children's tickets and brings in a total of $352. how many of each kind of ticket did she sell?

Stacey sold 22 children's tickets and 44 adult tickets.

Step-by-step explanation:

Let a and c represent the numbers of tickets sold.

Then a = 2c   (twice as many adult tickets as children's tickets)

Then the equation relating the dollar amounts is

($6/ticket)(2 c) + ($4/ticket)(c) = $352

Then $12c + $4c = $352, so $16c = $352.

Solving this for c, we get 22.  Then a = 2c = 2(22) = 44

Stacey sold 22 children's tickets and 44 adult tickets.

Volume of cylinder(V) is given by:

           ....[1]

where, r is the radius of the cylinder and h is the height of the cylinder

From the diagram:

Diameter of a pipe (d) = 10 cm

height of the pipe(h) = 2m    

Use conversion:

1 m = 100 cm

then

2m  = 200 cm

⇒h = 200 cm

Since, a pipe is in the form of cylinder.

We have to find the volume of a pipe.

We know that:

⇒

Divide both sides by 2 we get;

5 = r

or

r = 5 cm

Substitute the given values and use  π = 3.14. in [1] we have;

Simplify:

Therefore, the volume of a pipe in cm³ is, 15700
