Do 9 and 10 and yea.thanks

Number 9 is C. 1,000 ft^3

Number 10 is B. 144 in^3

Step-by-step explanation:

For both number 9 and 10, we are trying to find volume. Volume is the space within a three dimensional shape. To find the volume you do length × width × height. Knowing this we can start solving.

For number 9, the length is 20 ft, the width is 10 ft and the height/depth is 5 ft. Now we multiply these numbers.

20*10*5 = 1,000

This gives of 1,000. Since this is in feet, we add feet/ft at the end. Also since it is volume, you add ^3

1,000 ft^3

Now lets do the same for number 10

The length is 6, the width is 2 and the height is 12. Now multiply

6*2*12 = 144

This one is in inches so we add inches/in at the end. It is also volume so we add ^3 as well

144 in^3

9+10=21 EZ Geng shet. Give me brainliest :).

Also, the dude that did all that extra shii at the bottom is wrong lol

step-by-step explanation:

12: 00 p.m. to 7: 00 p.m. is a total of 7 hours.

4: 00 p.m. to 7: 00 p.m. is a total of 3 hours.

this means that from 4: 00 p.m to 7: 00 p.m. this represents 3/7 of what was lost from 12: 00 p.m. to 7: 00 p.m.

after knowing this, after doing 11,600 - 6,800 = 4,800

4,800 represents 3/7 of what was lost for 7 hours.

we then divide 4,800 by 3 which gets 1,600.

because we know that 1,600 represents 1/7 of how much water was lost, we just have to multiply by 7, which gets 11,200.   after adding 11,200 to how much water was left at 7: 00 p.m. which was 6,800. 11,200 + 6,800 = 18,000

this means that the pool originally had 18,000 gallons in the pool.

you can also check your work by doing 18,000 - 4(1600), which becomes           1800 - 6400 which gets you 11,600.
