Question

You can answer only this question, it's ok:

1)What would be the measurement of the smaller angle between the minute hand and the hour hand of a clock when the time is 4:40??
A: 100
B: 120
C: 140
D: 160
E: 180
Optional question:
2)Which equation will produce a line that will pass through the point (0, 0)?
A: x=2y+5
B: x=y-3
C: x=4y
D: x= 7y-2
E: x=y+x/3+20

Answer 1

1)100 or A
Angle = |30*H - (11/2)*M|, where H is the hours hand and M is the minutes hand

in this case: H = 4, M= 40
30*4 - (11/2)*40 = 120 - 220 = -100 = |-100| = 100
2)x=4y or C
If you plug in 0,0 you will get 0=4×0 or 0,0
