Answer:
The answer to your question is Ф = 210°; sin 120 = -1/2
Step-by-step explanation:
Data
Ф = 7π/6
∠ = ?
sin Ф = ?
Process
1.- Convert radians to degrees using proportions and cross multiplication
π rad ------------------ 180°
7π/6 rad ---------------- x
x = (7π/6 x 180) / π rad
x = (7 x 180) / 6
x = 1260/6
x = 210°
2.- Find the sin of 210°
sin 210 = -1/2
Answer:
A
Step-by-step explanation:
Answer: 1/5 or 20%
Step-by-step explanation: Since there are 5 questions and only one is correct, 1/5 of the options are correct. If a random selection being made, there therefore is a 1/5 chance that a correct answer is selected.
Actually it would be 4 hours $60 because the question says he earned the same amount of money at both jobs. The only place on the graph where both jobs earned the same amount for the same amount of time is where they intersect at 4 hours and 60$
