The right answer to 1b is 1 5/8 and the right answer to number 1e is 1 3/7. The way I solved this was by starting out adding two fractions at a time...

1b).     5/8 + 5/8 + 3/8
           5/8 + 5/8 = 10/8 or 1 1/4
           10/8 + 3/8 = 13/8 or 1 5/8.


1e).     5/7 + 1/7 + 4/7
           5/7 + 1/7 = 6/7
          6/7 + 4/7 = 10/7 or 1 3/7

In Death Valley, California, the highest ground temperature recorded was 94°C on July 15, 1972. In the formula C= 5/9 (F - 32) ,
gulaghasi [49]

Answer:

F=201.2\°

Step-by-step explanation:

we know that

\°C=\frac{5}{9}[\°F-32]

For C=94\°

substitute in the formula and solve for F

94=\frac{5}{9}[F-32]

(\frac{9}{5})*94=[F-32]

F=(\frac{9}{5})*94+32

F=201.2\°

Two pools are leaking, after 15 minutes pool A has leaked 2/3 gallon, after 20 minutes pool B has leaked 2/3 gallon. Which pool
shepuryov [24]

Answer:

Pool A.

Step-by-step explanation:

This can be solved through ratios. You would write it as \frac{gallons}{minutes} So, \frac{2/3}{15} for the first one, and \frac{2/3}{20} for the second. You might want to use a calculator for that part, but you could also change the gallons to cups, which gives you a much better number of 10.515. So, \frac{10.515}{15} = 0.701, and \frac{10.515}{20} = 0.52575 So, pool A is at a faster rate. If you want it in gallons per minute, it's by 0.01 (with the 1 repeating) gallons per minute. By cups, it's 0.17525 cups per minute.

(The reason I did not do this by cross multiplying and dividing ratios is because it gives you the exact same answer if you are finding it per one, as I am here with per one minute. You can do it this way, it just wastes a bit of time.)
