Answer:
Step-by-step explanation:
60 sec= 1 min
60min=1hour
24hours=1day
7days=1week
52 weeks =1 year
24x7= 168hours in a week
168hours x 52 =8736 hours in a year
8736x60=524160mins
524160mins= 1 year
the heart beats 103680 in a year
the heart will beat 524160/103680=5.05555555556 in a minute
Answer:
<u>Range = 1 1/4</u>
Step-by-step explanation:
Range = Maximum - Minimum
Arranging the data in ascending order :
- <u>1/2, 5/8, 3/4, 1 1/4, 1 1/2, 1 3/4</u>
<u />
Solving for range :
- Range = 1 3/4 - 1/2
- Range = 1 3/4 - 2/4
- Range = 7/4 - 2/4
- Range = 5/4
- <u>Range = 1 1/4</u>
1. x=−y+8−z
2.x=−7−4y−5z (everything over 4)
3.x=2−z
1.y=-x+8-z
1.z=-x+4-y
2.y=7+4x-5x (everything over 4)
2.z=7+4x-4y (everything over 5)
3.z=2-x
