MakcuM [25]3 years ago
5 0

Answer:

A) 64x + 285 = 605

B) 5 hours

Step-by-step explanation:

64x + 285 = 605

64x + 285-285 = 605 - 285

64x = 320

64x/64 = 320/64

x = 5

Double check

($605 Total - $285 parts) / $64 Hourly rate = Labor per hour

$320 Labor / $64 Hour = 5 hours

or 64x

A rhino can run at speeds of about 28 miles per hour. What is that speed in
swat32

<u>Given</u>:

A rhino runs at a speed of about 28 miles per hour.

We need to determine the speed in feet per second.

<u>Converting miles to feet:</u>

The miles can be converted to feet by multiplying 5280 with 28 miles per hour.

Thus, we have;

28\times 5280=147840

Thus, the speed of the rhino in feet per hour is 147840

<u>Converting hours to seconds:</u>

The hours can be converted into seconds by dividing 147840 by 3600 (Because an hour has 60 seconds in a minute and 60 minutes in an hour)

Thus, we get;

Speed=\frac{147840}{3600}

Speed = 41.066667

Rounding off to the nearest whole number, we get;

Speed =41

Therefore, the speed of the rhino is 41 feet per second.

Hence, Option B is the correct answer.

Marcus earns 15% commission on his total sales at work.
IrinaVladis [17]

Answer:

Option C

Step-by-step explanation:

Given the following question:

Total cost is $725
15% Marcus makes in commission.

In order to find the answer, we have to find 15% of $725 and that number will be the total in commissions he earned that week.

\frac{15\times725}{100} =15\times725=10875\div100=108.75

Marcus makes "$108.75" or option C in commissions last week.

Hope this helps.
