Answer:
5.0 days
Step-by-step explanation:
From the question given above, the following data were obtained:
Initial mass (N₀) = 46 g
Constant (K) = 0.1374 /day
Half life (t₁/₂) =?
The half life (t₁/₂) is related to the decay constant according to the following equation:
t₁/₂ = 0.693 / K
With the above equation, we can obtain the half-life of the substance as follow:
Constant (K) = 0.1374 /day
Half life (t₁/₂) =?
t₁/₂ = 0.693 / K
t₁/₂ = 0.693 / 0.1374
t₁/₂ = 5.04 ≈ 5.0 days
Thus, the half-life of the substance is 5.0 days
Malachy- $9
Gavin- $3
Gavyn- $6
Solution;
Add up all the numbers in the ratios. So 3+1+2 is 6. Now do the money ($18) divided by the tattled up ratio (6). 18 divided by 6 is $3 which is now equal to 1. Now for malachy you do his ratio (3) times our number equal to one of those ratios (3). 3 times by 3 is $9. Same for others. 1 times 3 is 3. 2 times 3 is 6.
