Answer:
59 bacteria would there be after 4 hours.
Step-by-step explanation:
Given:
Bacteria in the petri dish = 40
Time taken for the bacteria to be doubled =17 hours
To Find:
To Find the number bacteria left after 4 hours = ?
Solution:
By using the proportionality,
After 17 hours the number of bacteria will be 80.
Let the number of bacteria after 4 hours be x
then
Now by cross multiplication
x= 18. 82
So the number of bacteria after 4 hours will be
= 40 + 18.82
= 58.82
=59
Let d equal the final amount it depreciates.
Let m equal the number of months.
Since d is the final amount, we put this at the very end of the equation.
Since it depreciates $25 every month, this number is going to be subtracted from the total price of the tablet ($650).
The final equation comes out too: d = 650 - 25m
Best of Luck!
