Jim has 20-inch wheels on his bicycle (their diameter is 20 inches). the tires are worn out, and he would like to cut them into pieces to use as a bumper on something he's making. estimate the length of rubber jim would get from his two bicycle tires. ≈ 60 in. ≈ 40 in. ≈ 120 in. ≈ 136 in.

120 in.

Step-by-step explanation:

Given : Jim has 20-inch wheels on his bicycle (their diameter is 20 inches).

Then, the radius of the tire =

Now, the length of rubber we got from each tire is given by Circumference.

Circumference of a circle is given by :-

i.e. the length of rubber we got from each tire is 62.8 inches.

Now , the length of rubber Jim would get from his two bicycle tires :-

Hence, the estimated length of rubber Jim would get from his two bicycle tires. = 120 in.

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.
