1/6 of half a rotation = 1/12 of a rotation = 1/12 of 360 degrees = 360/12 = 30 degrees.
It will have moved through: (50/60)*360 = 300 degrees
Every minute is six degrees. At 7:30, the hour hand has moved halfway between the 7 and 8. Call it 15 degrees.
Angle of 360 degrees = 1 hour = 60 minutes of time so 6 degrees = 1 minute of time so 72 degrees = 12 minutes of time. I have used "minutes of time" as the unit of time to avoid confusion with minute as a unit in which angles are measured (1/60 degree).
0 degrees. No -- this is a trick question. At 6:00 the hands are at 180 degrees, but by the time the minute hand has moved to 30 minutes the hour hand has moved on to half way between '6' and '7', so the angle between the hands is 360/24 degrees = 15 degrees.
0 degreesEach hour mark is worth 30 degrees. The hour hand will have moved 1/4 of 30 (7.5 degrees) from the 3 o'clock mark. The minute hand is on the 3 o'clock mark. That puts the hour hand 7.5 degrees ahead of the minute hand.

The terminology is CFM, Cubic Feet per Minute.

1 hour = 60 minutes therefore: It would have moved (1/60) x 60 minutes = 1 degree
When there rotates something, you can declare the speed of rotation as degrees per time. A period is defined as the time needed when the rotating thing has reached the same position, having 360° moved around the own axis.
The minute hand, which is pointing at 3 is at right angles to 12. But the hour hand is no longer pointing at 12. The hour hand does not stay at 12 from 12:00 to 12:59 and then jump through 30 degrees at 1 o'clock. By 12:15, the hour hand has moved 7.5 degrees (clockwise) so at 12.15 the angle is 90-7.5 = 82.5 degrees.
The angle between the hour hand and the minute hand on a standard clock at 6:30 is 15 degrees. Let's review the movement of the hands of the clock specific to this problem. The hour hand moves through the 12 hours of half a day in 12 hours (naturally), and that translates into the hour hand moving 360 degrees in 12 hours. That means the hour hand moves 360/12, or 30 degrees per hour. That translates into 15 degrees in half an hour. If the hour hand is pointing straight down at 6:00 (which it is), it will move 15 degrees from where it was in half and hour. And the time will be 6:30 with the minute hand pointing straight down. The minute hand will be pointing to where the hour hand was half an hour ago. And, as stated, the hour hand will have moved from dead on the six and gone 15 degrees further around.
The hour hand moves 360/12=30 degrees every hour (so in 12 hours it moves 360 degrees -- back to where it started). One minute is 1/60 of an hour, so in 1 minute the hour hand moves 30/60=1/2 degree. In the meantime the minute hand has moved 1/60th of the distance around the clock, or 1/60 x 360 = 6 degrees. So at 12:01 the angle between the hands is 6 - 1/2 = 5 1/2 degrees
