1$ = 100 cents,    1 hour = 60 minutes

$7.80/hour =  (7.8*100) cents / (1*60)minutes
 
                   =  780 cents/60 minutes
 
                   = 13 cents/minute

Answer:

correct option is:

b. 13

Step-by-step explanation:

We know that:

1$ = 100 cents

and 1 hour = 60 minutes

So,

$7.80/hour = (7.8×100) cents / (1×60)minutes

                    = 780 cents/60 minutes

                    = 13 cents/minute

Hence, The correct option is:

b. 13

A computer hard drive contains a circular disk with diameter 2.5 inches and spins at a rate of 7200 RPM (revolutions per minute)
PIT_PIT [208]

Now to solve this problem, all we have to remember is the formula for calculating the linear speed given the radial speed, that is:

v = r w

where,

v = is the linear velocity or linear speed

r = is the radius of the circular disk = (1 / 2) diameter = (1/ 2) (2.5 inches) = 1.25 inches

w = is the radial velocity (must be in rad per time) = 7200 rev per minute

 

Calculating for v:

v = 1.25 inches (7200 rev per minute) (2 π rad / 1 rev)

v = 56,548.67 inches / minute

 

Converting to miles per hour:

v = 56,548.67 inches / minute (1 mile / 63360 inches) (60 min / hour)

<span>v = 53.55 mile / hour</span>
