Let c be total cost, while m is the minutes above the base minutes;
C=34.99+0.23*m
C=34.99+0.23m
Note, m= total minutes - 100
For part a,y < x y > -2xPoint B: (3,1) plugin x=3, y=1 y < x 1 < 3which is true, so point B satisfies the first inequality.
Not sure... about part C though sorry...
If the spinner is evenly divided then they all have a 25% chance
Answer: 46 degrees
Explanation:
Angle PRS = 98 degrees
The two smaller pieces add up to this larger angle, so,
(anglePRQ) + (angleQRS) = angle PRS
(3x-8) + (2x+6) = 98
5x-2 = 98
5x = 98+2
5x = 100
x = 100/5
x = 20
Then we can find each angle
- angle PRQ = 3x-8 = 3*20-8 = 52 degrees
- angle QRS = 2x+6 = 2*20+6 = 46 degrees
Notice how 52+46 = 98 to confirm the answers.
