Answer:

Answer C

Step-by-step explanation:

If the polygon has n sides, then the number of diagonals the polygon has is

(n - 3)*n/2

So for a seven sided figure the number of diagonals would be

(7 - 3)(7)/2 = 4*7/2 = 28/2 = 14

3.25 liters.

<h3>Further explanation</h3>

<u>Given:</u>

Mrs.Henderson makes punch by mixing 10.9 liters of apple juice, 0.6 liters of orange juice, and 8 liters of ginger ale.
She poured equally into 6 bowls.

<u>Question:</u>

How much punch is in each bowl?

Express your answer in liters.

<u>The Process:</u>

The two steps for obtaining the amount of punch in each bowl are as follows:

<u>Step-1: </u>the total amount of punch after mixing is the sum of apple juice, orange juice, and ginger ale in liters.

$\boxed{ \ 10.9 \ liters + 0.6 \ liters + 8 \ liters = 19.5 \ liters \ }$

<u>Step-2: </u>the total amount of punch divided by the number of the bowl is the amount of punch in each bowl.

$\boxed{ \ 19.5 \ liters \div 6 \ bowls = \boxed{ \ 3.25 \ liters/bowl \ } \ }$

Let's also consider the following quick steps.

<u>Quick steps:</u>

$\boxed{ \ \frac{(10.9 + 0.6 + 8) \ liters}{6 \ bowls} = \frac{19.5 \ liters}{6 \ bowls} = \boxed{ \ 3.25 \ liters/bowl \ } \ }$

Therefore, the amount of punch in each bowl is 3.25 liters.
