Abarber gives 16 haircuts in 5 hours. in minutes, at what rate is the barber giving one haircut? how many haircuts can he give in 8 hours? a) 12 minutes; 40 haircuts b) 15 minutes; 32 haircuts c) 18.75 minutes; 25 haircuts d) 21 minutes; 22 haircuts

C)18.75 minutes; 25 haircuts

Step-by-step explanation:

5 hours = 5 * 60 minutes = 300 minutes

5 hours for 16 haircuts =

= 300 minutes: 16 haircuts

= 300/16 minutes : 16/16 haircuts

= 18.75 minutes : 1 haircut

8 hours = 8 * 60 minutes = 480 minutes

480/18.75 = 25.6

18.75 * 25.6 minutes : 1 * 25.6 haircuts

480 minutes : 25.6 haircuts

Since 0.6 haircut is not a full haircut, he can give 25 haircuts in 480 minutes.

9.55 degrees.

step-by-step explanation:

the given angle is

1 cycle is equal to 2π radians. so 4π will be equal to two cycles.

5.166667π-4π = 1.166667π

hence, this angle goes a little more than negative x axis.

1.166667π-π= 0.166667π

hence, the reference angle is 0.166667π radians.

1 radian = 57.2958 degrees

now, in degrees, this should be equals to 9.55 degrees.

ok then what happened.
