Answer:
i think 11
Step-by-step explanation:
Basically, how this question looks like in numerical form is:
39.1 - (33 1/3% × 42.12)
33 1/3% can be changed to 1/3. {For e.g., 1% can be changed to 0.01 or 1/100}
Thus,
39.1 - (1/3 × 42.12)
= 39.1 - (42.12 ÷ 3)
= 39.1 - (14.04)
{Break the number up if you are doing mental sums}
= 39.1 - 10.00 - 4.00 - 0.04
= 29.1 - 4.00 - 0.04
= 25.1 - 0.04
= 25.06

Answer:
y=Ae^(1.25t)
Step-by-step explanation:
From the expression y=Ae^kt
After two days of the experiment, y = 49 million, t=2
After four days of the experiment, y= 600.25 million, t=4
A is the amount of bacteria present at time zero and t is the time after the experiment (in days)
At t=2 and y =49
49=Ae^2k…………….. (1)
At t=4 and y = 600.25
600.25=Ae^4k………… (2)
Divide equation (2) by equation (1)
600.25/49=(Ae^4k)/(Ae^2k )
12.25=e^2k
Take natural log of both sides
ln(12.25) =2k
2.505 =2k
k=1.25
The exponential equation that models this situation is y=Ae^(1.25t)
Hello!
You have to find the average of the numbers
To find the average you add all the numbers up and divide that by the amount of numbers you added
39 + 54 + 43 + 52 + 60 + 55= 303
Then you divide by the amount of numbers added
303/6 = 50.5
We can round this up
The answer is 51
Hope this helps!
