Will give brainliest! I just need the answer to part B.

do 20times 5 divided by 20times5divided by ur anwser or in other words ahahaha

Step-by-step explanation:

You’re using Pythagorean theorem (a^2 x b^2 = c^2) for this problem. “a” is the base of the triangle, “b” is the height and “c” is the hypotenuse.

(20)^2 x (25)^2 = c^2

(400) x (625) = c^2

1025 = c^2

*square root “c” and do the same to 1025*

c = 32.01562

*round*

32 m

step-by-step explanation:

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.
