A healthy human heart beats about 1,533,000 times a year. A sparrow's heart beats about 241,776,000 times in a year. About how m

Galina-37 [17]

Answer:

About 158 times

Step-by-step explanation:

Represent the rate of human heart with H and sparrow's heart with S

$H = 1,533,000\ times$

$S = 241,776,000\ times$

Required

Determine how many times faster is S than H

To do this, we simply divide S by H i.e.

$Number = \frac{S}{H}$

$Number = \frac{241,776,000}{1,533,000}$

$Number = 157.714285714$

$Number = 158$ --- approximated

Hence, the sparrow's heart beats about 158 times faster than the human hearts

Pachacha [2.7K]

3n=27+3
you can do anything as long as you do it to both sides
3n=27+3
add like terms
27+3=30
3n=30
divide both sides by 3
n=10
