Required area = lb + 2 × h ( l + b)
= 4 × 3 + 2 × 7 (4 + 3)
= 12 + 14 × 7 = 12 + 98 = 110 m²

Cost of white-washing at the rate of $6/m²
= $ 110 × 6 = $ 660

Kevin caught some fish. Of them 4/9 were herring, and 2/9 salmon. What was the total amount of fish, amount of herring and amoun
julia-pushkina [17]

There were 3 different fish caught, Salmon, Herring and Flounder.

4/9 were Herring, 2/9 were Salmon, 4/9 +2/9 = 6/9

This means 3/9 were Flounders ( 3/9 + 6/9 = 9/9 = 1)

3/9 can be reduced to 1/3.

1/3 of the fish were Flounders.

Divide the amount of flounders by the portion caught:

12 / 1/3 = 12 * 3/1 = 36 total fish.

Now you have total number of fish, multiply the total by each portion for each type of fish.

Total fish = 36

Herring = 4/9 x 36 = 16

Salmon = 2/9 x 36 = 8

Peter owns a candy store. His starting balance last month was $15,300.
ValentinkaMS [17]

The Time interval is one month, hence the burn rate is the difference between the starting and the ending balance is $2,800

<h3>Monthly Burn Rate Computation</h3>

Given Data

  • Starting Balance =  $15,300
  • Ending Balance =  $12,500
  • Time Interval = 1 months

Difference between Starting and Ending Balance

= 15,300- 12,500

= 2,800

We have found the difference between the Starting Balance and the ending Balance as $2,800
