19539 bacteria will be present after 18 hours
<u>Solution:</u>
Initial value of bacteria N = 6000
Value after 4 hours 
= 7800
<em><u>The standard exponential equation is given as:</u></em>
where
N is amount after time t
No is the initial amount
k is the constant rate of growth
t is time
Plugging in the values in formula we get,
Solving for "k" we get,
Taking "ln" on both sides, we get
On solving for ln, we get k = -0.0656
The equation becomes, 
Now put "t" = 18,
Hence the bacteria present after 18 hours is 19539
Answer:
75 words in one minute
Step-by-step explanation:
If Lolo typed at the same rate each minute, we can find w from ...
15w = 1125 . . . . . the number of words typed in 15 minutes
w = 1125/15 = 75
Lolo typed 75 words in 1 minute.
Answer:
125 minutes
Step-by-step explanation:
one paper takes 25 minutes to complete. Now if we multiply that by 5 papers you get 125 minutes
Answer:
1/9
Step-by-step explanation:
Becuase there are 9 people invited, so they all have a 1/9 chance
Doubling in size,
if the whole dish is filled in an hour (all of it)
how long does it take to fill 1/2 dish?
notice that
1/2 doubled=1/2 times 2=2/2=1 whole dish
therefor it only doubled one more time from the 1/2 point
1hour=all
1hour-6mins=1/2 dish
1hour-6mins=60-6=54 minutes
answer is 54 minutes
