I need help with this ASAP and can you explain so i can understand?!

Elanso [62]

Answer:

Adult tickets sold = 225

Student Tickets sold = 375

Step-by-step explanation:

Let:

Adult tickets sold = x

Student Tickets sold = y

Total tickets sold = 600

So, we can write: x+y = 600

Total money collected = 3037.50

Cost of 1 Adult ticket = $6.00

Cost of one Student ticket = $4.50

So, we can write: 6x+4.5y=3037.50

Now, we get a system of equations, that if solved we can find values of x and y

Let:

$x+y = 600--eq(1)\\6x+4.5y=3037.50--eq(2)$

We can solve using substitution method.

Finding value of x from eq(1) and putting it in eq(2)

$We\:have\\x+y=600\\x=600-y$

Put in eq(2)

$6x+4.5y=3037.50\\6(600-y)+4.5y=3037.50\\3600-6y+4.5y=3037.50\\-1.5y=3037.50-3600\\-1.5y=-562.5\\y=\frac{-562.5}{-1.5}\\y=375$

So, we get value of y = 375

Now put value of y in eq(1) to find value of x

$x+y=600\\Put\:y=375\\x+375=600\\x=600-375\\x=225$

So, we get value of x = 225

The Tickets sold will be:

Adult tickets sold = x = 225

Student Tickets sold = y = 375

adelina 88 [10]

Answer:

The volume of the cylinder B is 251.2 cubic inches.

Step-by-step explanation:

Given : The volume of a cylinder varies jointly with the square of its radius and with its height: Cylinder A has a volume of 254.34 cubic inches and has a radius of 3 inches and a height of 9 inches.

To find : What is the volume of cylinder B, which has a radius of 4 inches and a height of 5 inches?

Solution :

The volume of a cylinder varies jointly with the square of its radius and with its height i.e. the volume is

$V=k r^2h$

Where, k varies jointly

Now, Cylinder A has a volume of 254.34 cubic inches and has a radius of 3 inches and a height of 9 inches

i.e. V=254.34 cubic inches , r=3 inches and h=9 inches

Substitute values in the formula,

$254.34=k\times3^2\times 9$

$254.34=k\times81$

$k=\frac{254.34}{81}$

$k=3.14$

Now, The volume of cylinder B, which has a radius of 4 inches and a height of 5 inches is given by,

$V=3.14r^2h$

$V=3.14\times 4^2\times 5$

$V=3.14\times 16\times 5$

$V=251.2in^3$

Therefore, The volume of the cylinder B is 251.2 cubic inches.
