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:
-72
Step-by-step explanation:
step1: c/-9=8
step2: c= -72
Answer: AD = 9cm
Step-by-step explanation: This is a 30-60-90 triangle, so the hypotenuse is equal to twice the length of the short side of the right angle.
BC is the short side of the large triangle, so AB, the hypotenuse of the large triangle is 2×6, 12 cm
BC is also the hypotenuse of the small triangle, ΔBCD, so it is twice the length of BD, to that makes BD = 6/2= 3
Subtract BD from AB.
That's 12 - 3 = 9 the length of AD
Answer:
Step-by-step explanation:
<u>Assumed it is:</u>
<u>Converting into vertex form:</u>
- f(x) =
- - x² + 16x - 13 =
- - (x² - 16x + 64 - 64) - 13 =
- - (x - 8)² + 64 - 13 =
- - (x - 8)² + 51
M= -8/6 = -4/3 which can go to -1.3 but u can keep it as a fraction if it needs to be
