Answer:

The muscular work completed by four men will be 2400 ft. lbs.

Step-by-step explanation:

See the diagram of the ramp.

Four men carry 20 boxes each up a ramp as shown.

So, 4 men carry total (4 × 20) = 80 boxes up the ramp and each box weighs 5 pounds.

Then, the 4 men carry total (80 × 5) = 400 lb weight up the ramp.

Now, the vertical height of the ramp from the ground level is 6 ft.

Hence, the muscular work completed by four men will be (400 × 6) = 2400 ft. lbs. (Answer)

6. As part of their employee benefits, all workers at Light and Power Electric Company
Semenov [28]

Answer:

  $1769.06

Step-by-step explanation:

The sum of Mia's three highest salaries is ...

  $92,000 +94,800 +96,250 = $283,050

so the average is ...

  $283,050/3 = $94,350

Her pension is then ...

  0.01875 × $94,350 = $1769.06

_____

<em>Additional comment</em>

This is equivalent to the total of those salaries, divided by 160.

  T/3 × 0.01875 = T × (0.01875/3) = T × 0.00625 = T/160

Sometimes, there are simpler ways to calculate things like this.
