<h3>Answer:</h3>
  • A: 7 inches
  • B: 6 inches
<h3>Step-by-step explanation:</h3>

We can let the variables A and B stand for the length in inches of fish A and fish B, respectively.

If we assume each person bought fish having a total length of 1 inch per gallon of aquarium, then we can write equations ...

... 3A +2B = 33 . . . . . total length of Marta's fish

... 3A +4B = 45 . . . . . total length of Hank's fish

Subtracting the first equation from the second, we get ...

... 2B = 12

... B = 6 . . . . . divide by 2

Using this value in the first equation, we have ...

... 3A + 2·6 = 33

... 3A = 21 . . . . . . . . subtract 12

... A = 7 . . . . . . . . . . divide by 3

Fish A is 7 inches long; fish B is 6 inches long.

Yesterday, 64% of the 6th grade students chose to drink chocolate milk with their lunch. What fraction of 6th grade students Did
Talja [164]

Answer:

\frac{9}{25}

Step-by-step explanation:

100-64=36

Percentages put into fractions will be Percentage over 100.

So, the fraction will be \frac{36}{100}. Now simplify.

\frac{36}{100}=\frac{18}{50} =\frac{9}{25}

Of the 725 students at Franklin Middle School, 12/25 play a sport. How many students play a sport at Franklin Middle School?
Paladinen [302]

Answer:

348 out of 725

Step-by-step explanation:

This is a ratio question, giving us a sample that we can use to extend the number to all students.

12/25 students play a sport so we want the value of x in x/725

So:

12/25 = x/725

Cross-Multiply:

25x = 8700

Divide by 25 to get x:

348

You can also check by dividing these ratios to see if you get the same number. In this case, you do (.48).

Serenity has 2\frac{1}{2} 2 1 ​ cups of dough to make dumplings. If she uses \frac{3}{4} 4 3 ​ cup of dough for each dumpling, h
BARSIC [14]

3 dumplings can be made by Serenity

<em><u>Solution:</u></em>

Given that,

Serenity has 2\frac{1}{2} cups of dough to make dumplings

She uses \frac{3}{4} cup of dough for each dumpling

To find: Number of whole dumplings made

From given information,

\text{Total cups of dough } = 2\frac{1}{2} = \frac{2 \times 2+1}{2} =\frac{5}{2}

\text{Cups of dough for 1 dumpling } = \frac{3}{4}

To find the number of whole dumplings made, we can divide the total cups of dough by cups of dough for 1 dumpling

\text{Number of whole dumplings made } = \frac{\text{total cups of dough}}{\text{cups of dough for 1 dumpling}}\\\\\text{Number of whole dumplings made } = \frac{\frac{5}{2}}{\frac{3}{4}} = \frac{5}{2} \times \frac{4}{3}\\\\\text{Number of whole dumplings made } = \frac{10}{3} = 3.33 \approx 3

Thus 3 dumplings can be made
