A truck driver travels at 59 miles per hour. The truck tires have a diameter of 30 inches. What is the angular velocity of the w
Misha Larkins [42]

Answer:

661.4\ rpm

Step-by-step explanation:

we know that

1 mile=63,360 inches

step 1

Find the circumference of the wheels

C=2\pi r

we have

r=30/2=15\ in -----> the radius is half the diameter

substitute

C=2\pi(15)

C=30\pi\ in

assume

\pi =3.14

C=30(3.14)=94.2\ in

Remember that    

The circumference of the wheels represent one revolution

Convert 59 miles per hour to inches per minute

59\ mi/h=59*63,360/60=62,304\ in/min

using proportion find the number of revolutions  

\frac{1}{94.2}\frac{rev}{in}=\frac{x}{62,304}\frac{rev}{in}\\ \\x=62,304/94.2\\ \\x=661.4\ rev

therefore

substitute

62,304\ in/min=661.4\ rev/min=661.4\ rpm

The monthly rent for a pizza parlor is $1,200. The average production cost per pizza is $6. 75. The monthly expenses for the piz
lukranit [14]

By using the concept of profit, it can be calculated that

Profit function = 5.75 x - 1200

What is profit?

If the selling price of an article is more than the cost price of the article, the difference between the selling price and cost price gives the profit

Monthly expense for a pizza parlor C(x) = 1,200 + 6. 75x

Revenue function = 12.5x

Profit function = R(x) - C(x)

                       =  12.5x - (1200 + 6.75x)

                       = 12.5 x - 1200 - 6.75x

                       = 5.75 x - 1200
