In order to fill his fish tank to capacity Jamal needs to put 25 gallons of water into the tank. If Jamal has 12.5% of the tank filled with water, how much more water does he need to put into the tank

21.875 gallons

To Know:

Keep in mind a percent divided by 100 becomes a decimal.

There are two ways to solve this problem.

The first is to find how much water is in the fish tank already:

     We can set up a proportion to solve. This proportion has units of percentage on the top and gallons on the bottom.

     It will help us to find how much water is in the fish tank:

1x = 3.125

x = 3.125

     Now we can solve for how much water is needed to fill the tank:

25 - 3.125 = 21.875 gallons

The second is to find how much is needed using the percentages:

100% - 12.5% = 87.5%

Now to find how much is needed:

25 * 0.875 = 21.875 gallons

Have a nice day!

the equation cos(35) =a/25 can be used to find the length of bc what is the length of bc? round to the nearest tenth

step-by-step explanation:

3-4

step-by-step explanation:

the answer is 3-4 because both 45 and 60 has a multiple of 15.

45/3=15

60/4=15

therefore the odds against selecting a red is 4-3
