Aconvertible is traveling at 45 miles per hour, and its wheels have a diameter of 48 inches. how many complete revolutions do the wheels make in one minute?

The wheel make 315 complete revolutions in one minute

Step-by-step explanation: Given speed of convertible =45 miles/hr

Firstly we will convert miles to inches

We know that 1 mile= 63360 inches

So 45 miles=

i.e. speed=2851200 inches/hr

Now since the revolutions are asked in one minute

So speed=

=47520 inches/min

Now In one revolution distance travelled by wheel=2πr or πd

=

=150.72 inches

No of revolutions =Total distance travelled/Distance travelled in one revolution

=

=315.28 revolutions

answer: the value should be used for i in the formula of calculation the monthly payment , the interest rate per period is 0.85.

step-by-step explanation:

the given rate of interest i= 85%

in calculating the monthly payment for a loan with an interest rate compounded monthly, the value of the interest rate per period we use in the formula must be in decimal form.

to convert it in decimal, we divide it by 100, we get

hence, the value should be used for i in the formula of calculation the monthly payment , the interest rate per period is 0.85.
