Answer:

4. 94 degrees

5. 60 degrees

Step-by-step explanation:

4. This is a pentagon. By definition, all the angles should add up to 540 degrees. So, we can just add up all those expressions and solve for x:

(4x + 2) + 132 + (4x - 10) + (5x - 11) + 128 = 540

Combine like terms:

13x + 241 = 540

Solve for x:

13x = 299

x = 23

Now put this into the expression for angle P:

P = 4x + 2 = 4 * 23 + 2 = 92 + 2 = 94

Thus, P is 94 degrees.

5. Since angles 1, 2, and 3 are equal, then their supplementary angles are also equal. Say that each supplementary angle is x.

We also see that angle 4 = angle 3 + 10. We already set the supplementary of angle 3 as x, so that means that angle 3 = 180 - x (by definition of supplementary angles). This means that angle 4 = 180 - x + 10 = 190 - x. Angle 4's supplementary angle is the one inside the hexagon, and it will be: 180 - (190 - x) = x - 10.

Since angles 4 and 5 are equal, then their supplementary angles are equal, as well. So, the supplementary angle of angle 5 is x - 10.

Finally, we see that the last angle left to figure out in the hexagon is the one with the square. That is 90 degrees (by definition).

The sum of the angles in a hexagon, by definition, is 720. So, let's write all these expressions and set them equal to 720:

x + x + x + (x - 10) + (x - 10) + 90 = 720

Combine like terms:

5x + 70 = 720

Solve for x:

5x = 650

x = 130

The supplementary angle of angle 5 is x - 10 = 130 - 10 = 120. So, the measure of angle 5 is 180 - 120 = 60.

Hope this helps!

Recent studies indicate that the average surface temperature of a planet has been rising steadily. Some scientists have modeled

jarptica [38.1K]

Answer:

a) The average global surface temperature in 2100 is 10.7°C

b) b) The slope of the function, 0.01, represents the rate of yearly increase of average surface temperature on the planet and the intercept represents the average surface temperature on the planet in 1900 (the reference year that the average surface temperature for subsequent years are calculated with respect to).

Step-by-step explanation:

T = 0.01t + 8.7

To predict the temperature of the planet in the year 2100.

We will calculate the number of years that 2100 is, since 1900

t = 2100 - 1900 = 200 years

T = (0.01 × 200) + 8.7 = 10.7°C

The average global surface temperature in 2100 is 10.7°C

b) The slope of the function, 0.01, represents the rate of yearly increase of average surface temperature on the planet and the intercept represents the average surface temperature on the planet in 1900 (the reference year that the average surface temperature for subsequent years are calculated with respect to).

Select the correct answer.

Answer:

a negative linear association (C)

Re-Written Problem [Formatted]

Teams with varying numbers of players are playing a group card game. the time taken by each team to complete one game is given in the table. What is the relationship between the two variables?

Numbers of players on team are going to be 1, 2 , 3, 4, 5.

time taken to complete game (in minutes) 32, 26, 20, 14, 8

(Select the correct answer)

A. Positive linear association

B. Exponential relationship

C. Negative linear association

D. No relationship

----------------------------------------------------------------------------------

Step-by-step explanation:

Lower x values (numbers of players on team) are correlated with higher y values (time taken to complete game)

<em />

<em>[note: I know which values are x and y because of a cause-and-effect relationship. x causes y. number of players causes a change in minutes {it wouldn't make sense for the number of time it took to cause the number of players} ]</em>

<em />

So, if we were to graph this relationship, we would see a downward-slope / negative slope of a line, because greater x-values are associated with lower y-values.

So, you would see a negative line, showing a negative linear association.
