Answer:
No inequality given but in my view answer is:
x ≥ 16
Step-by-step explanation:
Given that:
Total time = 6 hours
Remaining Time = 6 - 2 hours = 4 hours (40*6 =240 mins)
Time required for 1 centerpiece = 15 mins
We have to find inequality for x:
Number of centerpieces she makes = x
In 240 mins : 240/15 centerpieces can be made
= 16 centerpieces
If she works with the same speed or more efficiently the suitable inequality would be:
x ≥ 16
I hope it will help you!
Think of it backwards. To get the total measure of the interior angles of a polygon, you divide the polygon into triangles, where a base of each triangle makes up a side of the polygon, and every triangle shares a vertex towards the center of the polygon. We know that the sum of the interior angles in triangles is 180 degrees. Two of the 3 interior angles of each triangle make up the interior angles of the entire polygon. If you add up the third angle of each triangle, you will get 360 degrees. So, the sum of the interior angles of a polygon is equal to the number of sides the polygon has times 180 degrees minus 360 degrees. Written as an expression, you get:
180n-360, where n is the number of sides a polygon has.
Set this equal to 5400 to get the answer:
5400=180n-360
180n=5760
n=32
So the polygon has 32 sides.
