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:
400%
Step-by-step explanation:
We can write a percent proportion:
600/x = 150/100
a:b = c:d
a and d are linked and b and c are linked. So if a is missing, you would do (b*c)/d to get a, if b was missing, you would do (a*d)/c to get b, etc.
So over here we do
(600*100)/150 = 60,000/150 = 400, so x = 400, so that means it's 400% of 150
We can also use benchmark fractions which I find much easier:
100% of 150 is 150.
So 200% of 150 is 300
So 300% of 150 is 450
And 400% of 140 is 600
Every time it increases by 100%, it also increases by 150 on the other side, which makes sense
