Answer: 1 It's the hundreds place
Step-by-step explanation:
164.13
1 is hundreds 6 is tens 4 is one .(point) 1 is uniths and 3 is tenths
Anything after the decimal ends in (ths) (ones(uniths), tenths, hundreths) but since we only have to write
The underlined digit which is 1 it's only HUNDREDS or the hundreds place value
The answer is 9a+5. All you have to do is combine like terms:)
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
