So we want to know what percentage of bees would survive a virus after 19 days of decay if the bee population has a half life of 5 days. So every 5 days 50% of bees die. Lets say that N is the number of bees before the virus. So after 5 days is 50% less bees, so 50% of N remains. After another 5 days again, 50% bees die, and 50% out of 50% is 25%. So after 10 days, 25% of bees remain or 25%N or 0.25*N. After another 5 days its 12.5 % of bees remain or 0.125*N. And after 4 days 40% more bees die. And that is 0.4*0.125*N = 0.05N. 0.05*100% is 5%. So after 19 days, 5% of bees remain and 95% of bees is dead.

Answer:
Explained below.
Step-by-step explanation:
Assuming that the question is related to exponents.
Consider the expression:
Here,
<em>a</em> = base
<em>b</em> = exponent
Consider that the value of base is a negative term.
Then an even exponent will give a positive result.
And an odd exponent will give a negative result.
Consider the following values of <em>b</em> and suppose that <em>a</em> = -<em>x</em>.
For <em>b</em> = 4,
For <em>b</em> = 3,
Answer:
30 grams
Step-by-step explanation:
So, first I had to figure out what 1 tin weight. Which was 350 grams because I divide 5 into 1750. Then I did 350+4 which gave me 1,400. I knew that there was three packets so 30 grams per packet should be the answer because 30×3 is 90 grams.
