Is means equal

of means multiplication

so

20 = 40% x a

40% = 40/100 = 4/10 = 2/5

So

20 = 2/5 x a

Multiply both sides by 5/2

20 x 5/2 = a

10 x 5 = a

a =50

So your final answer is \boxed{\bf{50}}

A person's resting heart rate is typically between 60 and 100 beats per minute. Noah looks at his watch, and counts 8 heartbeats
sweet-ann [11.9K]

Answer:

h=48

Step-by-step explanation:

You should create an even proportion. So you could do seconds over heartbeats or the other way around. I decided to do the other way around. Since yu want to see h in m minutes and in a minute there are 60 seconds, I did 8/10 = h/60. Instead of cross multiplying, I saw that 10 times 6 is 60 so 8 x 6=h. 8 x 6 = 48 so h=48.
