Each cell divides to form two new cells every 30 minutes. If a culture starts out with exactly 100 bacterial cells how many bact
adelina 88 [10]
So, after 30 mins we have:

100*2

After 1 hour: 100*2*2, etc


the number of 2s will be the number of time they will divide: 3 hrs divided by 0.5 hour: this is six times.

So the final number of cells will be:

100* 2^{6} =100 *2*2*2*2*2*2= 100 *8*8=100 *64=6400


So after 3 hrs there will be 6400 cells there!

In triangle JKL, m of angle J = 90, m of angle K = 30, and m of angle L = 60. Which of the following statements about triangle J
Lynna [10]

Answer:

option C. KL=2*JL

option D. JK=\frac{\sqrt{3}}{2}*KL

option F. JK=\sqrt{3}*JL

Step-by-step explanation:

step 1

we know that

In the right triangle JKL

sin(30\°)=\frac{JL}{KL}

sin(30\°)=\frac{1}{2}

so

\frac{1}{2}=\frac{JL}{KL}

KL=2*JL

step 2

cos(30\°)=\frac{JK}{KL}

cos(30\°)=\frac{\sqrt{3}}{2}

so

\frac{\sqrt{3}}{2}=\frac{JK}{KL}

JK=\frac{\sqrt{3}}{2}*KL

step 3

tan(30\°)=\frac{JL}{JK}

tan(30\°)=\frac{1}{\sqrt{3}}

\frac{1}{\sqrt{3}}=\frac{JL}{JK}

JK=\sqrt{3}*JL
