If the average heart rate is 60 beats per minute approximately how many times will a heart beat in a year

The average heart beats approximately 31557600 times a year.

Step-by-step explanation:

60 x 60 = 3600 beats per hour

3600 x 24 = 86400 beats per day

86400 x 365.25 = 31557600 beats per year

answer: 12

step-by-step explanation:

d. bc = 12 and ef = 16

step-by-step explanation:

we are given that δabc : δdef such that .

also, it is given that

so, from the options, we need that .

a.

b.

c.  

d.

as, we can see that only option d gives the same ratio as i.e. .

hence, the possible lengths are bc = 12 and ef = 16.
