If the heart of a human beats 72 times in 1 minute. Find, in what time will the heart beat 204 times?
Lelechka [254]

Hello!

your answer is: 2 minutes, 49 seconds, and 800 milliseconds

to get this, divide 204 by 72. that gives you the amount of minutes the heart was beating, which is 2.83 minutes

then, multiply 2.83 by 60 to get the seconds

you have 169.8 seconds.

2 minutes is equal to 120 seconds, so subtract that from 169.8

that leaves 49.8 seconds

.8 seconds is equal to 800 milliseconds

so put it all together and you have: 2 minutes, 49 seconds, and 800 milliseconds

I hope this helps, and have a nice day!

Please help me out ‼️
Westkost [7]

Answer:

7

Step-by-step explanation:

In similar triangles, corresponding elements are proportional. Then we get,

(2x + 1)/(x-1) = 10/4

4(2x +1)       = 10(x-1)

8x + 4         = 10x - 10

8x               = 10x - 14

2x               = 14

x                 = 7

Hope it helps and if it does, please mark me brainliest...
