The big polygon is double the size of the original, So the side question mark is 5 and the degrees is 1, 26.5 and 2, 41 degrees

Step-by-step explanation:

Answer:

So we know that these to shapes are scaled copies, so find two angles on them and see what they divid too. Example: A has 2.5 B has 5, if we divide 5 by 2.5 we get 2. And if we times 2.5 by 2 we get 5 as are total. We now know that 2 is going to be the number that helps us crack all of these angles.

B ANSWERS:

Because we know that 2.5 times 2 gets us 5 thats going to be the same answer for the angle on the right. In other words 5 is the answer for B's missing right angle.

If we follow the same formula we get 3 for B's missing left angle.

A ANSWERS:

This time instead of mutilplying we are dividing. 53/2 gives us 26.5, so 26.5 is the answer for the top right angle.

Same dividing, 41 is the answer for the bottom left missing angle.

Angles in a triangle always add up to 180 degrees

Here, we add up all the angles given to equal it to 180 degrees:

X + X + 10 + X + 5 = 180

Collect like terms -> 3X + 10 + 5 = 180

Add the whole numbers -> 3X + 15 = 180

Take 15 from to the other side (then make it negative) to isolate the X:
3X = 180 - 15

The subtract -> 3X = 165

Take 3 over to the other side (and it it should divide 165) and isolate the X -> X = 165/3

Finally, X = 55

Now wherever you see X in the triangle, replace it with 55.

With that, the top angle = 55 + 10 = 65 degrees
The bottom left angle = 55 + 5 = 60 degrees
The bottom right angle = 55 degrees

The price of Stock A at 9 A.M. was $12.57. Since then, the price has been increasing at the rate of $ 0.11 each hour. At noon the price of Stock B was $. It begins to decrease at the rate of $ 13.32 each hour. If the two rates continue, in how many hours will the prices of the two stocks be the same?

Answers

Answer:

Let the hours when they equalize=h, then we have:

12.25 + .13h=13 - .09h

.13h + .09h=13 - 12.25

.22h=.75 divide both sides by .22

h=.75/.22

h=3 9/22,  hours, when they will equalize.

Step-by-step explanation:

google lol i dont know whats going on here but.....

Part 1 You will need to measure five different people. Record your measurements on a piece of paper. Using a tape measure or ruler, measure the length (in inches) of a person’s left foot and then measure the length (in inches) of that same person’s forearm (between their wrist and elbow). Refer to the diagrams below. You will have two measurements for each person. (An easy way to measure the length of a foot is to have your subject stand on a piece of paper. Then, trace their foot and measure the outline once they move off the paper.) To measure the forearm, measure inside the arm, between the wrist and the elbow. Part 2 Organize your data and find the rate of change. Create a table of the measurements for your data. Label the forearm measurements as your input and the foot measurements as your output. Select two sets of points and find the rate of change for your data. Describe your results. If you had to express this relation as a verbal statement, how would you describe it? Part 3 Compare rates of change. The equation below can be used to find the length of a foot or forearm when you know one or the other. (length of the foot) = 0.860 • (length of the forearm) + 3.302 If you let y = length of the foot and x = length of the forearm, this equation can be simplified to y = 0.860x + 3.302. Using this equation, how long would the foot of a person be if his forearm was 17 inches long? What is the rate of change of the equation from Part A? Compare the equation from Part A to your data. Are they the same? Which has a greater rate of change? Why do you think the values are different? Is the relation in your data a function? Why or why not? Could the equation in Part A represent a function? Why or why not? Explain your answer.

A. Forearm (in)        Foot (in)

Sam   11.               10

Emma  8                  7

Dad  11                 10  

B. M=9-7 over 8-10 the answer is 2 over 2.

 

C.  For every forearm the foot is one inch smaller.

Part 3:

A. 0.860(17)+3.302

B. Y=17.922. They are slightly different.  Keren’s has a greater rate.  I think the values are different because they have different origins.

C. Yes, because it is an important part for rate of change. Yes it is a function because there can’t be any exponents greater than 1, and its not a straight line if you plug it in.

Step-by-step explanation:

This is just an example dont you the names

The table below shows the measurement of five different peoples and if I had to express this relation as a verbal statement, I would describe it as "The foot is one inch smaller for every short arm" and this can be determined by using the given data.

Part 1  and 2 --

Given :

You will need to measure five different people. Record your measurements on a piece of paper.Using a tape measure or ruler, measure the length (in inches) of a person’s left foot and then measure the length (in inches) of that same person’s forearm (between their wrist and elbow).

The table below shows the measurement of five different peoples.

Name          Forearm (inches)           Foot (inches)

Shruti                      10                                  9

Ali                            11                                  10

Alvi                           8                                    7

Tanisha                    10                                   9

Swati                         11                                   10                                    

The two sets of points in order to find the rate of change for your data are:

M = 9 - 7 over 8 - 10 so, by simplifying this the solution is 2 over 2.

If I had to express this relation as a verbal statement, I would describe it as "The foot is one inch smaller for every short arm".

Part 3  --

Given :

y = 0.860 x + 3.302

The foot of a person if his forearm was 17 inches long is given by:

y = 0.860(17) + 3.302

y = 14.62 + 3.302

y = 17.922

So, the foot of a person if his forearm was 17 inches long is 17.922.

By comparing the equation from part A to the data it can be concluded that they are slightly different.  

The greater rate of change is of Keren’s and I think the values are different because they have different origins.

Yes, the equation in part A represents a function because there are no exponents greater than 1.
