Answer: 7,864,320
Step-by-step explanation:
Because the doubling time is 20 minutes, the bacteria would have gone through binary fission(cell division in bacteria) 18 times after 6hours(6*60/20)
Nt=N0 * 2^n
N0=starting population
n=number of times bacteria divide
So
30*2^18=7,864,320
Answer:
Percentage decrease ( from $4.09 to $3.59) is 0.1% ( Rounded to nearest tenth)
Percentage increase (from $3.59 to 4.09) is 0.1% ( Rounded to nearest tenth)
Percentages are not same for the both price changes. As we can see from the calculations percentage change from $3.59 to $4.09 is higher.
Step-by-step explanation:
$4.59 has been changed to $4.09.
Percent change = [(Value after - Value before) / Value before]*100
=
%
=
%
=
%
=
% ( Rounded to nearest tenth)
Percentage decrease is 0.1% ( Rounded to nearest tenth)
Now lets calculate the percentage change from $3.59 to $4.09.
Percent change = [(Value after - Value before) / Value before]*100
=
%
=
%
=

=
% ( Rounded to nearest tenth)
Percentage increase is 0.1% ( Rounded to nearest tenth)
Percentages are not same for the both price changes. As we can see from the calculations percentage change from $3.59 to $4.09 is higher.
