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.
Given = b = 20cm, A = 500cm2 l=?
A = l×b,
500= l×20
l= 25
<em>THE LENGTH IS 25 CM</em>
Multiplying by 1/5 is the same as dividing by 5, so we can show a diagram of division. This can be done by constructing a horizontal line of length 30 cm and dividing it into 5 equal parts; each part will measure 6cm.
