Answer:

V ≈ 94.25

Step-by-step explanation:

Using the formula $V = \pi r^{2} \frac{height}{3}$ you can plug in your information. It will turn out to be $V = \pi 3^{2} \frac{10}{3}$ . Then you solve

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

Jeans are reduced from 28.00 to 18.20 during a sale at a department store. What percentage was the original price reduced?

Natali [406]

Answer:

The original price was reduced 35%

Step-by-step explanation:

we know that

Jeans are reduced from $28.00 to $18.20

In this problem

The original price of 28.00 represent 100%

using proportion

Find out what percentage represent the difference between the original price and the new price

$\frac{28}{100}=\frac{28-18.20}{x}\\\\x=100(9.8)/28\\\\x=35\%$

therefore

The original price was reduced 35%

What is the measure of the central angle of a circle with radius 15 ft that intercepts a 10 ft arc?

olga2289 [7]

L=10ft
R=15ft
We have to find theta

$\Large{\underline{\sf Solution:-}}$

$\\ \sf\dashrightarrow L=\dfrac{\Theta}{180}\times \pi r$

$\\ \sf\dashrightarrow 10=\dfrac{\Theta}{180}\times 3.14\times 15$

$\\ \sf\dashrightarrow 10=\dfrac{\Theta}{180}\times 47.1$

$\\ \sf\dashrightarrow \Theta=\dfrac{10(180)}{47.1}$

$\\ \sf\dashrightarrow \Theta=\dfrac{1800}{47.1}$

$\\ \sf\dashrightarrow \Theta=38.2°$
