If you flip the 30-60-90 triangles so they look similar, and find the difference between the length of 60, and the length of 40.
40÷60 =.6666 etc
You can prove this by plugging in
60 •.66666 = 39.9999 or about 40.
The triangle I started with had a length of 60, so just used the tangent of 60° to find the adjacent.
Since we know the relationship of the triangles,
Multiply your answer, 103.923 •.666666
Which equals 69.2819
69.2819 is the length of the 40 triangle.
Add them together, and you get 173.2049.
Or 173.20 m
By adding or subtracting from the exponent in an exponential, it can cause the graph to be translated left or right on the grid.
By adding or subtracting from an exponential function, it can cause the graph to be translated up or down on a grid.
Maybe go about it this way:
40 divided by 5 equals 8
0.5 divided by 5 equals 0.1
Therefore, you add the two together to get the answer of 8.1

Answer:
Option D) B and C
Step-by-step explanation:
we know that
To find out the percentage of high school teachers that have a second job, divide the number of teachers that have a second job by the total number of teachers
<em>Survey A</em>
Convert to percentage
<em>Survey B</em>
Convert to percentage
<em>Survey C</em>
Convert to percentage
<em>Survey D</em>
Convert to percentage
Compare the percentages
Surveys B and C have the same percentage
therefore
Surveys B and C show proportional results, because the ratio of the number of teachers that have a second job by the total number of teachers is equal (this number is the constant of proportionality k in a proportional relationship between two variables)
