Step-by-step explanation:
the sum of the angels of this picture is equal to (n-1)×180
our n=7, the sum of the angles is equal to (7-1)×180=1080
1080=122+125+148+107+126+131+x
x=1080-759
x=190

Find the multiplier for 21.6% decay
Answers
Answer:
5pts
Step-by-step explanation:
The required multiplier for 21.6% decay is 78.4%.
Given that,
To find the multiplier for 21.6% decay
The percentage is the ratio of the composition of matter to the overall composition of matter multiplied by 100.
What is simplification?
The process in mathematics to operate and interpret the function to make the function simple or more understandable called simplifying and the process is called simplification.
In the question, the multiplier for the rate of 21.6% decay is to be determined.
A multiplier of decay implies decay = 1 - r
Since let the Decay multiplier be x
x = 1 - r
x = 1 - 0.216
x = 0.784
x = 78.4%
Thus, the required multiplier for 21.6% decay is 78.4%.

Find slope intercept form.
(M=1/2) (6,3)
Answers
Answer:
y = (1/2)x
Step-by-step explanation:
Start with that form: y = mx + b. Substitute 1/2 for m, 6 for x and 3 for y, for the purpose of finding the value of the y-intercept, b:
3 = (1/2)(6) + b. Thus, b = 0 and the desired equation is y = (1/2)x.

This line segment will be dilated with the point of dilation at (4, 1) and a scale factor of 2. What is the x-coordinate of one of the endpoints of the dilated segment
Answers
The x-coordinate of one of the endpoints of the dilated segment should be 8.
Calculation of x-coordinate:In the case when a coordinate point (x, y) should be dilated by a factor k, so the coordinate should be (kx, ky).Since the coordinate (4,1), so if this coordinate is dilated by a factor of 2 so the new coordinate points should be at (2(4), 2(1))Now
New point = (8, 2)

Answers
Answer:
A
Step-by-step explanation:
You need to find the slope in A. y = x + (4x - 1) = 5x -1. The slope is 5.
In B, as x increases 1 unit, y increases 1 unit. Therefore, the rate of change is 1/1 = 1
Conclusion: In A the rate of change is 5 and in B the rate of change is 1.
Therefore, A has a greater rate of change
