Answer:
18.51 grams.
Step-by-step explanation:
We have been given the decay rate
We have general equation for decay which is:
;
Here, we are given with initial sample which is a=300
b=1-13%
And t is 20 years.
We will subatitute the values in the formula we get:
After simplification we get y=18.51 grams.
The sample remain will be 18.51 grams.
Answer:
This means that the answer is the second option.
Step-by-step explanation:
First, lets convert everything to its decimal form.
Now we have the numbers:
As all of these numbers are negative we could look at each of these numbers as if they were positive and put them in descending order
This means that the order would be
The last thing we need to do is change those two decimals back to their mixed number forms
9514 1404 393
