Answer
It will take (t) = 24 hours to reach 300 .
Step by step explanation
It doubles every 15 hours. initial bacteria = 100
We need to find how long it take for the bacteria cells to increase to 300.
300 = 100(2)^t/15
300/100 = 2^t/15
3 = 2^t/5
Taking "ln" both sides, we get
ln(3) = t/15 ln(2)
t/15 = ln(3)/ln(2)
t/15 = 1.585
t = 1.585 * 15
t = 23.78 hours
t = 24 hours to nearest whole hours.
Thank you.

Step-by-step explanation:
well, it is a combination of 2 shapes.
I, personally, would have split it into the small 2x2 square (in the top right corner) and then into the 6x(7-2) rectangle.
that would be
2x2 + 6x5 = 4 + 30 = 34 cm²
but you started a valid approach too.
you "sliced" off a narrow rectangle along the whole right side. 7x2.
and that leaves now a 4x(7-2) rectangle.
so,
7x2 + 4x5 = 14 + 20 = 34 cm²
yes, this was my answer.
how did this suddenly appear as your answer ?
