Answer:
2,38kg
Explanation:
Mass in function of time can be found by the formula: 
, where 
is the initial mass, t is the time and k is a constant.
Given that a sample decay 1% per day, that means that after first day you have 99% of mass.
, but 
, so we have 
, then 
Now using k found we must to find 
.
The answer will be pressure.
Pressure is force per unit area.
Add 35 to 215. then divide by 25. you should get x=10
Answer:
4,800?
First I subtracted 8 from 24 because there are 24 hours in a day ad she spends 8 of those hours sleeping. I then took the answer which was 16, and multiplied that by 60 to find out how many minutes were in 16 hours and I got 960. I then multiplied 960 by 5 because she winks 5 times each minute. This left me with the answer 4,800.
