Answer:
Joe worked 3 hours overtime.
Step-by-step explanation:
Let t = number of hours overworked
425 + 20 × t = 485
425 + 20t = 485
20t = 485 - 425
= 60

t = 3
Joe worked 3 hours over time.
Hope this helps :)
Answer:
y = 126.43
Step-by-step explanation:
Essentially what you have is the Cosine(50)
Cos(50) = adjacent / hypotenuse
adjacent = 122
hypotenuse = ?? = y
Solve
Cos(50) = 122/y Multiply both sides by y
y*cos(50) = 122 Divide by cos(50)
y = 122 / cos(50) Find the value of cos(50)
y = 122 / 0.96497 Divide
y = 126.43
Answer:
The minute hand covered 120 degrees
Step-by-step explanation:
Minute hand completes 1 round in 60 minutes
1 round =
So, The minute hand covered degrees in 60 minutes = 
The minute hand covered degrees in 1 minute 
Phillip watched a beach volleyball game from 1 P.M. to 1:20P.M.
So, He watched it for 20 minutes
So,The minute hand covered degrees in 20 minutes =
Hence The minute hand covered 120 degrees
