Answer:

<h2>30% of 8 cups is 2.4 cups</h2>

Step-by-step explanation:

\bold{METHOD\ 1:}\\\\p\%=\dfrac{p}{100}\\\\30\%=\dfrac{30}{100}=0.3\\\\30\%\ of\ 8\ cups\to0.3\cdot8\ cups=2.4\ cups

\bold{METHOD\ 2:}\\\\\begin{array}{ccc}100\%&-&8\ cups\\\\30\%&-&x\end{array}\qquad\text{cross multilpy}\\\\100x=(30)(8)\\\\100x=240\qquad\text{divide both sides by 100}\\\\\dfrac{100x}{100}=\dfrac{240}{100}\\\\x=2.4

A regular assignment has 15 sides.Calculate the size of each interior angle
MariettaO [177]

Answer:

The measure of an interior angle of a regular 15-gon is 120°.

Step-by-step explanation:

We need to determine the measure of the size of an interior angle of a regular 15-gon having 15 sides.

Thus,

The number of sides n = 15

Hence,

Using the formula to determine the measure of an interior angle of a regular 15-gon is given by

(n - 2) × 180° = n × interior angle

substitute n = 15

(15 - 2) × 180 = 15 × interior angle

13 × 180 = 15 × interior angle

Interior angle = (10 × 180) / 15

                      = 1800 / 15

                      = 120°

Therefore, the measure of an interior angle of a regular 15-gon is 120°.
