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!

A half-filled cylindrical water tank has a water level of 20 feet high. The tank can hold 6000 cubic feet of water. Find the dia

Anettt [7]

Answer:

d = 13.8 feet

Step-by-step explanation:

Because we are talking about cubic feet of water, we need the formula for the VOLUME of a cylinder. That formula is

$V=\pi r^2h$

We will use 3.141592654 for pi; if the tank HALF filled with water is at 20 feet, then the height of the tank is 40 feet, so h = 40; and the volume it can hold in total is 6000 cubic feet. Filling in then gives us:

$6000=(3.141592654)(r^2)(40)$

Simplify on the right to get

$6000=125.6637061r^2$

Divide both sides by 125.6637061 to get that

$r^2=47.74648294$

Taking the square root of both sides gives you

r = 6.90988299

But the diameter is twice the radius, so multiply that r value by 2 to get that the diameter to the nearest tenth of a foot is 13.8
