Answer:
10,219 bacteria
Step-by-step explanation:
In this question, we are asked to calculate the population of bacteria in a culture given the formula for the population increase.
From the question, we know the formula to use is
Pt=Po*2^t/d
From the parameters in the question, we identify that Pt is ?, Po is 8300 bacteria , t is 3 hours and d is 10 hours which is the doubling time. Inserting these figures we have;
Pt = 8300 * 2^(3/10)
Pt = 8300 * 2^0.3
Pt = 10,218.5
Pt = 10,219 bacteria to the nearest whole number
I think its c. because m-7 is difference and + 15 is increasing
<h3>I'll teach you how to solve (1/5x-4+2y)+(2/5x+5-4y)</h3>
-----------------------------------------------------------------
(1/5x-4+2y)+(2/5x+5-4y)
Remove parentheses:
1/5x-4+2y + 2/5x+5-4y
Group like terms:
1/5x+2/5x+2y-4y-4+5
Add similar elements:
3/5x+2y-4y-4+5
Add similar elements:
3/5x-2y-4+5
Multiply:
3x/5-2y-4+5
Add subtract the numbers:
3x/5+1-2y
Your Answer Is 3x/5+1-2y
