Answer:
4/10 = 14/35
Step-by-step explanation:
We need to compare 4/10 with 14/35
4/10=2/5
14/35=2×7/(5×7)=2/5
Since we have 2/5 on both sides, these fractions are equal.
Two dimensional six sided figure.
It has 6 sides and 6interior angles that add up to 720 degrees.
It has six vertices.

Answer:
There will be 50 bacteria remaining after 28 minutes.
Step-by-step explanation:
The exponential decay equation is
N= Number of bacteria after t minutes.
= Initial number of bacteria when t=0.
r= Rate of decay per minute
t= time is in minute.
The sample begins with 500 bacteria and after 11 minutes there are 200 bacteria.
N=200
= 500
t=11 minutes
r=?
Taking ln both sides
To find the time when there will be 50 bacteria remaining, we plug N=50, = 500 and in exponential decay equation.
Taking ln both sides
minutes
There will be 50 bacteria remaining after 28 minutes.
