Answer:
I'm sorry I have no clue what this is. What grade are you in? I'm in seventh and I have never learned anything like this lol.
Step-by-step explanation:
3)first you count the sides
There are 8 sides
The equation of of finding the sum of all the interior angles is (n-2)*180
(8-2)*180
=6*180=1080
To find the measure of one interior angles divide the answer by the number of sides
900/8=112.5
4)first you count the sides
There are 7 sides
The equation of of finding the sum of all the interior angles is (n-2)*180
(7-2)*180
=5*180=900
To find the measure of one interior angles divide the answer by the number of sides
900/7= 128.57

The graph shows Marcia's walk.
Which statement best describes what Marcia could be doing on the interval from B to C?
A. Marcia is running home.
B. Marcia is walking home.
C. Marcia is turning a corner.
D. Marcia is stopping to rest.
Answers
Answer:
D. Marcia is stopping to rest
Step-by-step explanation:
At intervals B to C, we can see that Marcia's distance from home has not risen nor dropped. We can safely assume that she is not moving. Of course, time has not stopped, because the line continues to move from left to right. So, Marcia is likely stopping to rest for a moment.

please dont use me for points
Answers
Answer:
3 square centimeters.
Step-by-step explanation:
The measurements are 4 cm by 1.5 cm, so you can use the formula for area of a triangle (area = 1/2 * base * height) to figure it out.
Plug in base = 4, height = 1.5:
area = 1/2* 4 * 1.5 = 2 * 1.5 = 3.
The area is 3 sq. cm.

Jean made the qualitative statement, "The average weight of the raccoon population is 26 pounds." Is her statement reasonable? Complete the explanation.
Jean's statement (select) reasonable because the median value of the data is pounds.
Answers
Answer:
The average is 24 so her answer is reasonable cause it is not too far off.
Step-by-step explanation:
Average = sum/count
(16 + 18 + 18 + 24 + 25 + 27 + 28 + 31 + 31 + 32)/10
240/10

24 is close to 26

Shaded area is 55 units²
Step-by-step explanation:
Ignoring the white cutout, we have a rectangle of length 10 and width 7 (count the squares in each direction). The area of this larger rectangle is
(10 units)(7 units) = 70 units². The white area that we previously ignored has dimensions 3 by 5 units, and thus an area of 15 units²
Subtract the latter from the former, obtaining the net area
70 units² - 15 units² = 55 units²

Answers
Answer:
A, B, C, E, and F
To solve this problem, you should make sure to find the equation first. Start by doing rise/run with your two given points on the graph. From the point (-1,1) you rise 4 and then run 16 over to the point (3,2). That gives us a slope of 4/16 which can then be simplified to 1/4. That means that letter F tells us the equation of the line is y= 1/4x + 5/4.
From there you want to check your points, (3,2) and (-1,1). The first number is always x and the second number is always y. So you plug the point numbers into the equation we just found to see if they work. In the photos I inserted are how to do this step.
Once you have checked your points and you know for sure they're solutions, that gave you letters A and B. Since the point (1, 3/2) is also given in one of the answers we should check that point as well. (Also done in one of the photos) Since the point came out correctly that gives us letter C and also tells us there is more than 2 solutions. This means that letter E is also correct.
Hope this helped!
