Answer:
It will take 13.58 minutes until there are 80 grams of the element remaining
Step-by-step explanation:
An element with a mass of 990 grams decays by 16.9% per minute.
We are supposed to find how long will it be until there are 80 grams of the element remaining
Formula :
N(t)=Amount after t minutes
=Initial amount
r = rate of decrease = 0.169
t = time in minutes
Substitute the values in the formula :
t=13.58
Hence It will take 13.58 minutes until there are 80 grams of the element remaining

dr drazzle because his simplified form is most reasonable
Circumference has the answer in square units.
All you need to do is multiply 84 by 4.
The number of gallons by the number of quarts <em>in a gallon. </em>
80*4= 320
4*4=16
320+16= 336
There are 336 quarts of water supplied an hour.
