Answer:r=7/7744

move all terms to the left:

(7/22)(44)-(2r)=0

add all the numbers together, and all the variables

-2r+(+7/22)44=0

multiply parentheses

-2r+7/22*44=0

multiply all the terms by the denominator

-2r*22*44+7=0

multiply elements

-1936r*4+7=0

multiply elements

-7744r+7=0

move all terms containing r to the left, all other terms to the right

-7744r=-7

r=-7/-7744

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

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