Answer:
3(9a+8)
Step-by-step explanation:
have a nice day and week
Answer:
a. 20%
b. 40%
Step-by-step explanation:
a. 3km =3000m
600/3000×100=20%
b. 3200/8000×100=40%
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:
3/5x = 15
multiply both sides by 5
This cancels out denominator of fraction =
3x = 75
x = 25
