Answer:
The answer to your question is : 33.3 (Rounded).
Step-by-step explanation:
I got this answer by dividing 19.6 by 20, which gave me 0.98.
Then, I multiplied 0.98 by 34, which gave me 33.32.
After rounding, 33.3 is your answer.
Hope this helped!!

When we say "a is at most b" we mean that "a is less than or equal to b" or "a is not greater than b". So let's solve this problem as follows:
Step 1. Twice the difference of a number and 2
Let's call that unknown number as n. Then, twice the difference of a number and 2 is:

Step 2. Twice the difference of a number and 2 is at most -27

Answer:
It would take 24 minutes for the element to decay to 50 grams
Step-by-step explanation:
The equation for the amount of the element present, after t minutes, is:

In which Q(X) decays radioactively with a half life of 12 minutes.(0) is the initial amount and r is the rate it decreases.
Half life of 12 minutes
This means that 
So








If there are 200 grams of Element X, how long, to the nearest tenth of a minute, would it take the element to decay to 50 grams?
This is t when Q(t) = 50. Q(0) = 200.








It would take 24 minutes for the element to decay to 50 grams
