Which list could represent the four angle measures of a quadrilateral if one angle measures 125°?

A. 10°, 10°, 125°, 125°
B. 15°, 15°, 25°, 125°
C. 15°, 15°, 115, 125°
D. 55°, 55°, 125°, 125°

Answers

Answer 1

Answer: D

Step-by-step explanation:

The sum of the interior angles of a quadrilateral is 360°.

55+55+125+125=360

Answer 2

Answer:

D. 55, 55, 125, 125

Step-by-step explanation:

To solve this problem we first need to know what the total degrees of a 4 angle quadrilateral is. The answer to this is 360°. Knowing this, we need to figure out which combination of numbers adds up to 360. To do this, I go through the list and check all of the options.

A.) 10+10+125+125=270

B.) 15+15+25+125=180

C.) 15+15+115+125=270

D.) 55+55+125+125=360

Karla take 3min to edit 1/5. So she would take 15min to edit 1page. Then she would take 45min to edit 3pages.

45 minutes because if it takes 1/5 of a page in 3 mins.

1/5 = 3 mins
2/5 = 6 mins
3/5 = 9 mins
4/5 = 12 mins
5/5 = 15 mins

So 3 pages would be 15 x 3 which is 45

Answers

Well basically you just have to chose a number of sides for the side length of the square to be and move those many places to get another vertex of the square. For example if we have (-2,3) and we choose the side lengths to be 4 units than you could move 4 places up, down, left, or right to get the other vertices for the square

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.

What is (f+g)(x)?

g(x)=5x
Write your answer as a polynomial or a rational function in simplest form.

Answers

Answer:

-2x²-4x or -2x(x+2)

Step-by-step explanation:

(f+g)(x) means we are adding the values of f(x) and g(x):

f(x) = -2x²-9x

g(x) = 5x

(f+g)(x) = -2x²-9x+5x = -2x²-4x = -2x(x+2)
