Answer:
The polygon has 9 sides
Step-by-step explanation:
We need to equate the given expression to the given value and solve for n.
The sum of the interior angles, s, in an n-sided polygon is given by the expression:
We want to use this formula, to calculate how many sides has a polygon if the sum of the interior angles is 1,260°.
We solve the following equation for n.
Divide through by 180 to get:
Add 2 to both sides to get:
Hence the polygon has 9 sides
The cities are 9.6 inches apart on map.
Step-by-step explanation:
Given,
80 miles in actual = 0.75 inch
1 mile =
Distance between two cities = 1025 miles
1025 miles on map =
The cities are 9.6 inches apart on map.

Answer:
the average of this new list of numbers is 94
Step-by-step explanation:
Hello!
To answer this question we will assign a letter to each number for the first list and the second list of numbers, remembering that the last number of the first list is 80 and the last number of the second list is 96
for the first list
for the new list
To solve this problem consider the following
1.X is the average value of the second list
2. We will assign a Y value to the sum of the numbers a, b, c.
a + b + c = Y to create two new equations
for the first list
solving for Y
Y=(90)(4)-80=280
Y=280=a+b+c
for the second list
the average of this new list of numbers is 94
Answer:
The simplified form is
Step-by-step explanation:
To simplify the expression given to use, we need to reduce the given expression in its simplest form. There should not be any possibility for the further cancelling out of the division terms, if any.
Now the expression that is given to us is:
Here we will simplify it, as follows:
So this is the required simplified form.
