The perimeter of a square is 52 cm.<br> Calculate the area of the square

Nonamiya [84]

Answer:

$169cm^2$

Step-by-step explanation:

The perimeter is the sum of the side lengths of the shape. Since a square has equal side lengths, each side must be the same. Divide 52/4=13cm. 13cm is the length of 1 side. Area is length times width, and since each side is 13, multiply 13cm*13cm to get the area, which is $169cm^2$ ,

Deniz had a full gallon of milk. She poured out 4 cups of milk. There are 16 cups in 1 gallon. About what percent of the origina

Molodets [167]

Answer:

75% of the original volume is left.

Step-by-step explanation:

Deniz had a full gallon of milk, or 16 cups of milk, and then she poured out 4 cups of milk. That is:

$\\ A_{full-gallon} = \frac{16}{16}$ cups of milk, since $\\ \frac{16}{16} = 1$ or $\\ 1 * 100\% = 100\%$ of the original volume.
Deniz poured out 4 cups of milk from the 16 available (or $\\ \frac{4}{16}$ ).

Then,

The total left is:

$\\ Total_{left} = \frac{16}{16} - \frac{4}{16} = \frac{12}{16} = \frac{3}{4}$ , since we are dealing here with fractions with the same denominator.

In other words, $\\ \frac{3}{4} = 0.75$ is the amount of milk left in the container.

In terms of percentage, $\\ \frac{3}{4} = 0.75$ is equivalent to $\\ 0.75*100\% = 75\%$ of the original volume, because Deniz poured out $\\ \frac{4}{16} = \frac{1}{4} = 0.25$ or $\\ 0.25*100\% = 25\%$ from the original volume.
