Answer:
The polygon has 9 sides
Step-by-step explanation:
we know that
A regular polygon has equal length sides and equal interior angles
step 1
Find the measure of the interior angle
Remember that
The interior angle plus the exterior angle must be equal to 180 degrees (form a linear pair)
Let
x ----> the measure of each interior angle in the regular polygon
so

solve for x

step 2
Find the number of sides of the regular polygon
we know that
The measure of each interior angle in a regular polygon is given by the formula

where
n is the number of sides of the polygon
substitute the given values

solve for n

therefore
The polygon has 9 sides

Step-by-step explanation:
Commission on sales up to $ 3000 = 1% * 3000 = 0.01 * 3000 =$30
Commission over sales $3000 = 2% * ( 9650 - 3000)
= 0.02 * 6650 = $ 133
Total earning for a week = 120 + 30 +133 = $ 283
Answer:
67 inches
Step-by-step explanation:
Let's call the height of Louise 'L', the height of Miriam 'M' and the height of Jeffery 'J'.
Then, we can write the following equations and inequations:




Substituting J in the second and four inequations, we have:


If we assume the maximum value for M, in the first inequation we have that:

So the height of Uncle Louise is greater than or equal 66, and lesser than or equal 68, so his height could be 67 inches for example.
