For a polygon with 10 sides, which equation below represents the sum of the interior angles in the polygon?

sum = (360)(8) = 2880°
sum = (360)(10) = 3600°
sum = (180)(8) = 1440°
sum = (180)(10) = 1800°

Answers

Correct answer is:

1800°

the correct answer is 1440.

The equation to find the sum of interior angles in a polygon is s = 180(n-2), n being the amount of sides and s being the sum. To solve you would do s = 180(10-2), s = 180(8), and s = 1440. hopefully that makes sense haha. use the equation s=180(n-2) :))

A rancher’s herd of 250 sheep grazes over a 40-acre pasture. He would like to find out how many sheep are grazing on each acre of the pasture at any given time, so he has some images of the pasture taken by the state department of agriculture’s aerial photography division. Here are three samples of the images. Sample 1 4 Sample 2 1 Sample 3 9 What can the rancher conclude from these samples about how many sheep graze on each acre of the 40-acre pasture?

Answers

Answer:

Step-by-step explanation:

Based on the samples provided, the rancher can make some assumptions about the number of sheep grazing on each acre of the pasture.

Sample 1 shows 4 sheep grazing in an area of the pasture, which suggests that there may be approximately 10 sheep per acre (since 250 sheep divided by 40 acres equals 6.25 sheep per acre, and 4 is close to 6.25 divided by 0.6).

Sample 2 shows only 1 sheep grazing in an area of the pasture, which may indicate that some areas of the pasture are less densely populated with sheep than others.

Sample 3 shows 9 sheep grazing in an area of the pasture, which could suggest that some areas of the pasture are more densely populated with sheep than others.

Overall, based on these samples, the rancher could conclude that the number of sheep per acre varies across the 40-acre pasture, and that there may be some areas with higher or lower densities of sheep. However, it's important to note that these conclusions are based on a very small sample size and may not be representative of the entire pasture. Further analysis, such as additional aerial photos or on-the-ground observations, may be needed to get a more accurate picture of sheep density across the entire pasture.

Answers

Answer:

Table:

0,200

4, 262

8,344

12, 450

Population after 12 years is 450 deer

Initial population is 200 deer.

Step-by-step explanation:

You take the x in the table and plug it in as an exponent so you will need a calculator or multiple the 1.07 by that many times so 1.07 12 times multipled by itself. and the initial is 0 years so anything to the exponent of 0 is 1 so that show i got 200 for the x=0

13: what is the measure of angle y?

14: what is the measure of angle x?

15: what is the measure of angle z?

Answers

angle y and the angle measuring 76 degrees are opposite so they should be equal. this means angle y = 76 degrees.

angle x + angle measuring 76 degrees should = 180 (they are supplementary angles)

x + 76 = 180

180 - 76 = x

x = 104 degrees

angle z is opposite angle x so they are equal. angle z = 104 degrees

y is 76 because it’s vertical to the degree given and then z and x is 180-76 which equals 104. z and x are the same because they are vertical to each other
