In a regular polygon each interior angle is 140° greater than each exterior angle. Calculate the number of sides of the polygon​

Mathematics
1 answer:
pochemuha2 years ago
6 0

Answer:

18 sides.

Step-by-step explanation:

The interior and exterior angles sum to 180 so:

       I + E = 180

also  I - E = 140       (given)

So, adding to eliminate E:

      2I = 320

I = 160 degrees and the external angle E = 1809 - 160 = 20 degrees.

Since the sum of all exterior angles in a polygon = 360 degrees

- the number of sides = 360 / 20 = 18.

Question 3,4&5 Cindy bought a car for $21,330. A few years later she sold the car for $19,700.find the percent of change in
san4es73 [151]

The change in value was 8% which amounts to $1630

Further explanation:

The change in value is calculated by using the initial price and selling price of the car.

Given

Purchase Price = P = $21330

Selling Price = S = $19700

As the selling price is less than the purchase price, Cindy had loss.

Loss=L= Cost\ price-selling\ price\\=21330-19700\\=\$1630

Percentage of loss will be calculated as:

Percent\ loss=\frac{1630}{21330}*100\\=8\%

The change in value was 8% which amounts to $1630

Answer:

Systematic sampling

Step-by-step explanation:

An EPA contractor needing to test the concentration of a substance in ten samples out seventy samples provided form a single source at regular time intervals.

For the contractor to effectively carry out the testing he has to employ a Non-probability system of sampling which is called Systematic sampling, because in systematic sampling we can assume the population size (x ) which in this case is 70 and the sample size( n ) to be 10

He will have to select ;  ( x / n )^th of the sampling frame for best results
