N=(3/4)*h*d
--------------------
n=Number of hours she reads
h=Hour(s)
d=Days
--------------------
You see, with this formula - when d=2,
n=(3/4)*h*2=(6/4)*h=(3/2)*h=1.5 hours
So, in the space of 2 days, she had spent 1.5 hours reading.
Answer:
mean life = 8264.5 s
Step-by-step explanation:
k = - 0.000121
The relation is given by

Now, the mean life is the life time for which the sample retains.
The mean life is the reciprocal of the decay constant.
The relation between the mean life and the decay constant is

% means out of 100 so If its 6% that = .06 then just multiply
16.06 divided by 22 = 0.73 so the answer would be 73 cents? Sorry im from the UK and don't know about dollars/cents
