X is equal to X 1 because you would multiply x by 1 which would be x
The decay constant is i 0.1155, and there would be 16 mg left after 24 hours.
The relationship between the half-life, T₀.₅, and the decay constant, λ, is given by
T₀.₅ = 0.693/λ.
Solving for λ, we will multiply both sides by λ first:
(T₀.₅)(λ) = 0.693
Since we know the half life is 6 hours, this gives us:
6λ = 0.693
Dividing by 6, we have
λ = 0.693/6 = 0.1155.
The decay constant will be k in our decay formula, and N₀, the original amount of substance, is 250:
N(24) = 250e^(-0.1155*24) = 15.6 ≈ 16
Answer:
The answer is 54.5
Step-by-step explanation:
The median of a set of observations is the value in the middle in case there is an uneven number of observations or the average between the two values in the middle.
First we arrange the times from less time to longer times.
50 - 52 - 57 - 230 .
The values in the middle are 52 - 57
And the average between this two values is 54.5. Thus that is the median legth of time.
Answer:
1q = 2p
Step-by-step explanation:
One quart of liquid is the equivalent of 2 pints... one of the rare easy measures in the American measure system.
So, the equation needs to have 1 quart on one side, and 2 pints on the other side. It's an equation because both values are equal, just expressed in different units.
1 quart = 2 pints, then rewritten to match the variables given in the question:
1q = 2p
