KatRina [158]

Answer:

40 mph

Step-by-step explanation:

One hour includes 60 minutes

8/60=0.13(3 repeating)

You only need 15 minutes of time

Two mechanics worked on a car. The first mechanic charged $65 per hour, and the second mechanic charged $60 per hour. The mechan
Bess [88]

Answer:

First mechanic: 12.8 hours & Second mechanic:12.8 hours

First mechanic made 832$ & Second mechanic made 768$

Hope this is right. If not I apologize and please let me know:)

Step-by-step explanation:

First you would do 65+60=125. You do this to find how much they charge together. Then you would take the amount of money they make and divide that from 125: 1600/125=12.8. Now that you have 12.8 you would plug that in for each mechanic: 65 times 12.8=832 and 60 times 12.8=768. Now you have the amount of money each mechanic made and the amount of hours they worked.

Analyze the following budget, with an income of $750, to determine how much can be spent on food for the month. Month________ Bu
NARA [144]

The phrase "no more than" implies upper limit. The correct choice for food budget is: Option D. No more than $60 can be spent on food.

<h3>How to find the remaining amount after deduction?</h3>

Suppose that you had initial amount as A.

Let you deduce B, C, and D from it.

The remaining amount is obtained by subtraction.

Thus,

Remaining amount  = A - (B + C + D) = A - B - C - D

For the given case, the budget left for food is the remaining amount after all the expenses are reduced from the income.

Income = $750

Expenses except food: $20 + $75 + $85 + $260 + $250 = $690

Thus, budget left is $750 - $690 = $60

This remaining budget is left. The person can spent either full of it on food or less than it, but cannot spend more than it as that person doesn't have more than $60 left.

Thus:

Food budget is no more than $60.

or

Food budget ≤ $60

Thus,

The correct choice for food budget is: Option D. No more than $60 can be spent on food.
