Answer:
a.) 4 half lives have passed
b) 9.388 minutes
Step-by-step explanation:
Formula for exponential growth / decay is given as:
Where 
is the final population
is the initial population
is the growth factor
is the time taken for the growth 'b'
is the amount of time
Here, we are given that:
= 6. 9 grams
= 110.4 grams
min
To find:
a.) Number of half lives taken for the decay.
b.) Total time in the decay.
Solution:
a.) Number of half lives taken for the decay is nothing but equal to 
.
Putting the values in the formula, we get:
Therefore, the answer is:
<em>4 half lives </em>have passed.
b.) Total time of decay. We have to find the value of here.
From answer of part a.):
Answer:
Step-by-step explanation:
In order to Convert 3/11 into a decimal you have to divide 3/11 out. If you were to put the three on top and the 11 on the bottom (here's a little tip to make it easier " top dog stays out and snoopy stays in. Top dog would be 3 because it is on the top of the fraction. Snoopy would be the 11 which is on the bottom of the fraction.) so with that being said..... So if you do 3 divided by 11 The answer would be 0.27272727.....hope it helped...:)
Answer:
-10.7
Step-by-step explanation:
tThe answer is -10.7. What you do is 3/5+7/10 then, you subtract 12 which gives your the answer
Negative. If a negative number is "larger" (further away from zero) than a positive number, the result will be negative. You're basically subtracting a value that is greater than your starting value.
For example:
8 positive counters plus 18 negative counters:
This can be expressed as 8-18, which equals -10. The sign of the sum is therefore negative.
