Step-by-step explanation:
Circumference=PI*diameter
Circumference=3.14*19.5
Circumference=61.23 rounds to 61.2 so the answer is C
Since 1/8000 is 0.000125, we can move the decimal 4 terms to the right.
So that will be 1.25 • 10^-4

Answer:
B. 7.5 hours
Step-by-step explanation:
Assuming that both hoses fill at the same rate, then by simple proportion,
To raise the pool by 1 foot of water:
1 hose ---> takes 3 hours
2 hoses ----> fills twice as fast ---> will take half the time ---> 3/2 = 1.5 hrs
Hence with 2 hoses, it will take 1.5 hours to fill 1 foot of water.
to fill 5 feet of water, we will need 1.5 hours x 5 feet = 7.5 hours
Okay so an in and out box is a box is basically a tale. Do you have a rule ? so if you have a rule..(which i do not know) lets say the rule is +2. lets also say that the IN says 4. Then what would be the out ? The out would be whatever 4+2 is. So basically the "out" is the outcome.
