Zamira and Courtney share a 16 oz box of cereal. By the end of the week, Zamira has eaten 38 of the box, and Courtney has eaten
12345 [234]

Answer:

12/25 ths of the box is left.

Step-by-step explanation:

I'm assuming you mean 14% and 38%

If so then the first thing you'd do is put 38 and fourteen over 100 such as:

38/100 and 14/100.  You do that because since its a percentage, its the same as the number of that percentage over 100.

Since you now have like terms, you can add them together, in which you add the two numerators (top row), but leaving the denominator (bottom row) the same, and it would give you:

52/100

What you want to do after that is simplify it. Once you simplify it, the simplified version of this is technically still the same as the non-simplified version, just easier to use.

Once you simplify it once, you will get:

26/50 and then if you simplify it again, you'll get 13/25

KEEP IN MIND that this is the amount that HAS BEEN EATEN ALREADY.

After that, you wan to subtract your part from your whole meaning you'd subtract: 25/25 - 13/25

Going back to earlier, you subtract the numerator and leave the denominator the same ONLY because they have like terms(The DENOMINATORS match)

After subtracting, you will get an answer of 12/25ths, which cannot be further simplified either.

Hope this helped!

Find how many piranhas you can put in a cylindrical tank
mr Goodwill [35]

Answer: The correct answer is 10 piranhas.

Step-by-step explanation:

To calculate the total Volume of a cylinder we have to use the following formula:

Volume = Area * Height

Area = π * r²  , where r= radius

The diameter is always the twice the radius so the diameter is 4 feet in this case and the radius is 2 feet  so the area is

Area= 3.1416 * (2*2)

Area = 3.1416 * 4

Area = 12.5664 square feet

Volume = 12.5664 (area) * 1.25 (height).

Volume = 15.708 cubic feet

Each piranha needs 1.5 cubic feet so we have to divide the total Volume by the volume that each piranha needs

15.708/ 1.5 = 10.472 or ten pirahnas because we can't put a fraction of a piranha in the tank.

The table shows the results of rolling a number cube, with sides labeled 1 through 6, several times.
Natalka [10]
It looks like you are missing one value in your table. You have 6 sides of the die, however only 5 outcomes. Without this, we can't get a final answer. However, I can tell you how to solve the problem.

For the experimental probability, you need to add up all the 2's and 4's. Then, divide that number by the total amount of numbers. <span />
