Answer:
The ratio of the number of female teachers to the number of male teachers is 18:5.
Step-by-step explanation:
First: Review how to write a ratio:
To write a ratio, take the two quantities, and put them on both sides of a colon (:). So, our two quantities our 18 and 5. But, they need to be in a specific order:
There are 18 female teachers and 5 male teachers at Ashley's school. What is the ratio of the number of female teachers to the number of male teachers?
Since, they mentioned the number of female teachers first, we put the quantity of female teachers first. So we will write 18 first and 5 after. So, the ratio is 18:5.

Answer:
<u>The regular polygon has 13 sides</u>
Correct statement and question:
If the sum of the measures of the interior angles of a polygon is 1980°, how many sides does it have?
Source:
1,920° is not a valid value for a regular polygon. It should be either 1,980° or 1,800° (it has to be a multiple of 180). We pick 1,980° to answer the question.
Step-by-step explanation:
Let's recall that the formula of the sum of the interior angles of any polygon is:
Sum of Interior Angles = (n-2) * 180°, where n is the number of sides of the polygon.
Therefore, replacing with the value we know:
1,980 = (n-2) * 180
n - 2 = 1,980/180
n - 2 = 11
<u>n = 13</u>
