Since the sum of the exterior angles of a polygon is 360° and an angle of the regular polygon is 20°, then 360° / 20° is the number of sides. We find the answer = 18, an octadecagon

PROBLEM SOLVING A ski shop sells skis with lengths ranging from 150 centimeters to 220 centimeters. The shop says the length of

grin007 [14]

Answer:

$h > 189.66\ cm$ or $h< 129.31\ cm$

Step-by-step explanation:

Let

h ----> a skier's height in centimeters

we know that

A ski shop sells skis with lengths ranging from 150 centimeters to 220 centimeters

The interval of the skis is -----> [150,220]

The compound inequality that represents the heights (in centimeters) of skiers the shop does not provide skis is

$1.16h > 220\ cm$ ----> inequality A

$1.16h< 150\ cm$ ----> inequality B

<em>Solve inequality A</em>

$1.16h > 220\ cm$

Divide by 1.16 both sides

$h > 189.66\ cm$

<em>Solve inequality B</em>

$1.16h< 150\ cm$

Divide by 1.16 both sides

$h< 129.31\ cm$

therefore

$h > 189.66\ cm$ or $h< 129.31\ cm$
