Answer:
The interior angles of a regular hexagon are congruent
Step-by-step explanation:
we know that
A <u><em>regular polygon</em></u> is a polygon that all interior angles are equal in measure, and all sides have the same length.
The sum of the measure of the interior angles in a regular polygon is equal to
![S=(n-2)180^o](https://tex.z-dn.net/?f=S%3D%28n-2%29180%5Eo)
where
n is the number of sides
For n=6 (hexagon)
![S=(6-2)180^o\\S=720^o](https://tex.z-dn.net/?f=S%3D%286-2%29180%5Eo%5C%5CS%3D720%5Eo)
Divide by the number of sides
![\frac{720^o}{6}=120^o](https://tex.z-dn.net/?f=%5Cfrac%7B720%5Eo%7D%7B6%7D%3D120%5Eo)
In this problem we have
![(4x+40)^o=6x^o](https://tex.z-dn.net/?f=%284x%2B40%29%5Eo%3D6x%5Eo)
solve for x
![6x-4x=40\\2x=40\\x=20^o](https://tex.z-dn.net/?f=6x-4x%3D40%5C%5C2x%3D40%5C%5Cx%3D20%5Eo)
Verify the measure of the interior angle in a regular hexagon with the value of x
---> is ok
---> is ok
therefore
The interior angles of a regular hexagon are congruent
You would have to multiply $24 by 8% and then subtract from the total.
So, 24 x .8 = 19.2
24-19.2 = 4.8
$4.80 sales tax.
Answer:
<em>a Inferential statistics</em>
Step-by-step explanation:
Inferential statistics are among the two central statistics categories.
<em>To define and draw conclusions about the population, inferential statistics use a random sample of data gathered from a population.</em>
Inferential statistics are useful when it is not feasible or practical to analyze every member of a whole population.
Answer:
8/9 x 5
5 x 1/9 x 8
5 x 8 divided by 9
Step-by-step explanation:
5/9 = 0.5555*8 =4.444
8/9 = 0.8888*5 =4.444
5*1/9 = 0.5555*8 =4.444
5*8 = 40/9 =4.444
