The total capacity of the pool = 18000 gallon
The total volume of the pool when calculated to 2/5 = (2/5) * 18000
                                                                                   = 35000/5 gallons
                                                                                   = 7200 gallons.
Now it is given in the problem that that
Rate at which the pool is filled with water = 20 gallons per minutes
Then
20 gallons of water is filled in = 1 minute
So
7200 gallons of water will be filled in = 7200/20 minute
                                                           = 720/2 minute
                                                           = 360 minute
So 360 minute is required to fill the pool with 2/5 of the total volume of water.

Find the surface area plz
vladimir1956 [14]
Hi again! ;)

If we want to find the surface area of a cube, we need to find the area of one surface first, and then multiply that by 9, since there are 9 sides/surfaces on a cube.

Since each side of a square is the same, we first find the area of one surface:

9 × 9 = 81

Then, to find the surface area, we multiply 81 by 6:

81 × 6 = 486

The surface area is
486 \:  {in}^{2}

3 Shamaya went shopping for school supplies. She bought 2 packages of
allsm [11]

Answer:

a.  $17.83

b.  $82.17

Step-by-step explanation:

a.

We need to find total cost of all the items.

2 package of pencil for 1.98 each: Total = 1.98 * 2 = 3.96

1 binder for 7.69:  Total = 7.69

1 divider for 2.69:  Total = 2.69

1 pencil box for 3.49:  Total = 3.49

We sum all of these to get:

3.96 + 7.69 + 2.69 + 3.49 = $17.83

b.

She only spent 17.83 and she had 100 dollars. So we subtract amount spent (17.83) from total (100) to get remaining balance.

100 - 17.83 = $82.17

If the length and width of a rectangular solid are increased by 10% and the height is increased by 20%, by what percent is the v
9966 [12]
LWH=V

increasse by 10% means times 1.10
increase by 20% is times 1.20



L turns to 1.1L
W turns to 1.1W
H turns to 1.2H

(1.1L)(1.1W)(1.2H)=1.452LWH
so it is increased by 45.2%
