There are <em>six</em> (6) members of the family.

The first person in the row can be any 1 of the 6.  For each choice . . .
The 2nd person in the row can be any 1 of the other 5.  For each choice . . .
The 3rd person in the row can be any 1 of the other 4.  For each choice . . .
The 4th person in the row can be any 1 of the other 3.  For each choice . . .
The 5th person in the row can be any 1 of the other 2.  For each choice . . .
The 6th person in the row is the 1 who is left.

Total number of ways to line up = (6 x 5 x 4 x 3 x 2 x 1) = 720 ways .

This number is called " six factorial ", and it's written ' 6! ' .

What is the number of degrees in the smaller angle formed by the hour and minute hands of a clock at 5:44?
Arisa [49]

The hour hand of the clock moves 360 degrees in 12 hours.

The quantity of degrees the hour hand moves per hour is in this way 360/12 = 30 degrees.

The hour hand of the clock moves 360 degrees in 12 *60 = 720 minutes.

The quantity of degrees the hour hand moves every minute is accordingly 360/720 = 1/2 degrees.

So the hour hand moves 1/2 degree for each minute.

The minute hand moves 360 degrees in a one hour.

The quantity of degrees the minute hand moves every minute is accordingly 360/60 = 6 degrees.

At 5:44, the quantity of minutes the hour hand has moved is 5 * 60 + 44 = 344 minutes.

At a half degree for each minute, the hour hand has moved .5 * 344 = 172 degrees.

At 5:44, the quantity of minutes the minute hand has moved is 44 minutes.

At 6 degrees for each minute, the minute hand has moved 6 * 44 = 264 degrees.

The angle between the minute hand and the hour hand is along these lines 264 degrees minus 172 degrees = 92 degrees.

<span>Since that angle is under the 180 degrees, it must be the littler edge between the hour hand the minute</span>

VikaD [51]

Answer:

(5,11)

(0,1)

(-2,-3)

Step-by-step explanation:

y=2(5)+1

y=10+1

y=11

so... (5,11)

y=2(0)+1

y=0+1

y=1

so... (0,1)

y=2(-2)+1

y=-4+1

y=-3

so... (-2,-3)
