To start, find your equation, n=3000(.5)^t, n being your number of bacteria and t being your time. Now plug in 375 for n and solve for t, 375=3000(.5)^t, .125=.5^t,
![t=log_{.5} .125=3](https://tex.z-dn.net/?f=t%3Dlog_%7B.5%7D%20.125%3D3)
. This means your answer is 3 minutes. To check it, plug it into your equation. n=3000(.5)^t=3000(.125)=375
Answer:
249mm
Step-by-step explanation:
You find volume of the overall figure- 11 x 3 x 13= 429
Then find volumes of missing parts of overall complete figure and subtract from the overall volume....
5 x 4 x 3= 60
429-60=369
-------------------------------------
8 x 5 x 3= 120
369-120= 249
