How many sides does a regular polygon have if each exterior angle measures 20°?

2 answers:

6 0

Sum of exterior angles of any polygon is 360 degrees.
<span>Each exterior angle of a regular polygon = 360/n where n is the number of sides. </span>
<span>So, n = 360/20 = 18. Your answer is D

Hope this helps.</span>

The sum of the extrior angles always adds to 360
each exterior angle has to have a side to go with it

so
360/20=18 sides

answer is D

Absolute value inequalities. 10-4|9y-10|<-94

Ivahew [28]

Answer: $\begin{bmatrix}\mathrm{Solution:}\:&\:y4\:\\ \:\mathrm{Decimal:}&\:y4\\ \:\mathrm{Interval\:Notation:}&\:\left(-\infty \:,\:-\frac{16}{9}\right)\cup \left(4,\:\infty \:\right)\end{bmatrix}$

Step-by-step explanation:

$10-4\left|9y-10\right|$

$10-4\left|9y-10\right|-10$

$-4\left|9y-10\right|$

$\left(-4\left|9y-10\right|\right)\left(-1\right)>\left(-104\right)\left(-1\right)$

$4\left|9y-10\right|>104$

$\frac{4\left|9y-10\right|}{4}>\frac{104}{4}$

$\left|9y-10\right|>26$

$9y-1026$

$y4$

A manufacturer made 7,234 boxes of coffee stirrers.Each box contians 1000 stirrers.How many stirrers did they make?

mash [69]

To answer this, you multiple 1000 by 7,234 because each box comes with 1000, so if there are 7234 boxes, then you multiple the stirrers by the # of boxes

The perimeter of the hallway is 10 4/10 meters. What is the width, in meters, of the hallway?

Romashka [77]

So you have two of those--when you add those together, you get "seven and eight-tenths," or 7.8 The 2 shorter sides are what's left to still measure. If the total perimeter is 10.4, you get the shorter sides by: 10.4 - 7.8 = 2.6, but REMEMBER, the 2.6 is BOTH shorter sides added together, so each ONE of them is 1.3 SO... your hallway/rectangle is 3.9 meters on each long side, and 1.3 meters on each short side. i hope this helps you
