Since the ratio is 5:4, they had to multiply 5x11 to get the 55. Now multiply the 4x11 to get 44. When you add the 55 and 44 that's 99 which only leaves 1 for the independent.

Please help with this question
alekssr [168]

Step-by-step explanation:

so, that means we want to find the time t (days) after which N = No/2

because "half-life" means the amount of time until half of the substance has disappeared (or transformed into something else).

so, we have

No/2 = No × e^(-0.1481×t)

No = 2× No × e^(-0.1481×t)

1 = 2×e^(‐0.1481×t)

1/2 = 0.5 = e^(-0.1481×t)

ln(0.5) = -0.1481×t

t = ln(0.5)/-0.1481 = 4.680264555... ≈ 4.7 days
