Apump started filling an empty pool with water and continued at a constant rate until the pool was full. at noon the pool was 1/3 full, and 114114 hours later it was 3/4 full. what was the total number of hours that it took the pump to fill the pool?
a. 213213
b. 223223
c. 3
d. 312312
e. 323

3 hours

Step-by-step explanation:

The pool was filled at noon =

After hours the fool was filled =

So,water filled in pool in hours =

So,water filled in pool in hours =

of pool is filled in hours =  

Whole pool is filled in hours =  

Whole pool is filled in hours =  

Hence it took 3 hours the pump to fill the pool .

step-by-step explanation:

hello and welcome!

so, when we see the words "proportional" along with a table, we need to know that we're looking numbers that divide by the same thing.

looking at this table, we simply have to do a trial and error, and divide to see which numbers have the same quotient. if you look at choice a & c, they both have equal quotients for three of the numbers, with one exception, so those can't be the answer. looking at b, there is no similarity, so that can't be it. then, we see d; if you divide all the numbers in the table, you'll see that they all divide by two, which is a proportional relationship, and our answer!

also, always remember that the x will always be the number that goes into y, and somewhere behind this table, is a formula. for this specific table, the formula would be:

since our x-value is being divided by two to get the y-value. and if they were to ask for more numbers in the series, this is the formula you would use to find them.
