Answer:
degree measure = 360° × percent of data
Step-by-step explanation:
The ratio of the degree measure of a sector of a circle graph to 360° is the same as the ratio of the represented data to the whole amount of data.
The idea of a circle graph is that the area of the sector is proportional to the data being represented. That is, if the data represented is 10% of the whole, then the sector area is 10% of the whole. Sector area is proportional to the degree measure of its central angle, so the example sector would have a central angle of 10% of 360°, or 36°.
The ratio of the central angle of the sector to 360° is the same as the percentage of data that sector represents.
Answer: 5 (8-9x)
Step-by-step explanation:
25 x 2 - 45 x -10
50 - 45 x -10
40 - 45x
3 is the slope, (0,-5) is the y-intercept of the graph.
In this question, you're solving for d.
Solve for d:
5(-6 - 3d) = 3(8+7d)
Use the distributive property:
-30 - 15d = 3(8+7d)
-30 - 15d = 24 + 21d
Add 30 to both sides:
-15d = 54 + 21d
Subtract 21d from both sides
-36d = 54
Divide both sides by -36
d = -3/2
Answer:
d = -3/2 or -1.5
Answer:
Brooke has 9 problems for social studies.
Step-by-step explanation:
I used addition. I did 15 + 5 = 20. and after that I just knew that you have to add 9 to 20 to get 29, so I figured out that she has 9 social studies problems.
