Explanation:
Scientific notation is used to shorten the amount of zeros you have to write out for a number.
To take a number out of scientific notation, move the decimal a number of times equal to the exponent: in my example it would be 3. If the exponent is positive, move the decimal to the right; if it is negative, move the decimal to the left.

Explanation:
20%= 1/5 if u don’t know the percentage then u can simply by doing..
20/100 then u divide it. U can do this by any other numbers such as 2, 4,5,10 and 20. U can do which ever way u like but i would recommend doing it either by 10 or 20.
So if we divide it by 20 we do...
20/100 divided by 20= 1/5
Or
20/100 divided by 10= 2/10
2/10 divided by 2 = 1/5
You can see the bigger the number that fits in is faster, although u can do it any way u feel like doing.
So we have got 1/5 from 20%. Now we do...
1/5 divided by 20. So when we do this, we use the bottom number to divide it and the top number to times it.
So..
1/5 u could use as 20 divided by 5..
Then 1 times the number that u get from ur before sum.
The answer is 4.
Because 1/5= 20 divided by 5 = 4
Since we have a 1 left we do..
4 times 1 which is... 4.
( u don’t need to show these parts in doing ur working, but i am doing these so they can help u understand)
So the answer is 4 and is the original weight.
I hope this is clear and helps u! :D
Answer:
Heart failure is frequently the cause. Pressures in the heart rise when a sick or overworked left ventricle can't pump out enough of the blood it receives from the lungs. Fluid is pushed past the blood vessel walls and into the air sacs by the increasing pressure.
