Answer:
The central angle is 330 degrees
Step-by-step explanation:
The arc length is equal to the circumference time the fractional part of the circle
arc length = circumference * x/360
11 = 12 * x/360
Divide each side by 12
11/12 = 12/12 *x/360
11/12 = x/360
Multiply by 360
11*360/12 = x /360 *360
330 = x
The central angle is 330 degrees
Combine like terms.
5c = 45
Divide 5 on both sides.
c = 9
Hope this helps!
Answer:
84 is the highest possible course average
Step-by-step explanation:
Total number of examinations = 5
Average = sum of scores in each examination/total number of examinations
Let the score for the last examination be x.
Average = (66+78+94+83+x)/5 = y
5y = 321+x
x = 5y -321
If y = 6, x = 5×6 -321 =-291.the student cannot score -291
If y = 80, x = 5×80 -321 =79.he can still score higher
If If y = 84, x = 5×84 -321 =99.This would be the highest possible course average after the last examination.
If y= 100
The average cannot be 100 as student cannot score 179(maximum score is 100)
