Answer:
30°
Step-by-step explanation:
BF is a straight line, so therefore it is equal to 180°
Because of this we know that COF is 150°, so therefor, to find BOC, we must subtract:
180° - 150° = 30°
d = b - 3 / 10
Step-by-step explanation:
b = 10d + 3
- Place +3 in the other side of the equal sign
- + 3 becomes - 3
- b - 3 = 10
- Divide both sides by 10 to make d the subject
- b - 3 / 10 = 10d / 10
- d = b - 3 / 10
The formula for simple interest is I=pXrXt (interest=principal Times annual interest rate Times time (In years)) so the answer would be $111.

4.68/12 = 0.39 per ticket
4.50/10 = 0.45 per ticket.
So, we are better off taking 12 tickets for $4.68
Hope this helps!
