Morgarella [4.7K]3 years ago
6 0

Answer:

25%

Step-by-step explanation:

There are 6+8+10 = 24 cookies

P ( chocolate chip) = number of chocolate chip/ total

                               = 6/24 = 1/4

Changing to percent

1/4 = 25/100 = 25%

A storage tank contains a liquid radioactive element with a half-life of 96 years. It will be relatively safe for the contents t
PolarNik [594]

Answer:

The tank must remain intact for 1183 years.

Step-by-step explanation:

Exponential equation for decay:

The amount of a substance after t years is given by:

A(t) = A(0)e^{rt}

In which A(0) is the initial amount and r is the decay rate.

A storage tank contains a liquid radioactive element with a half-life of 96 years.

This means that A(96) = 0.5A(0), and we use this to find r.

A(t) = A(0)e^{rt}

0.5A(0) = A(0)e^{96r}

e^{96r} = 0.5

\ln{e^{96r}} = \ln{0.5}

96r = \ln{0.5}

r = \frac{\ln{0.5}}{96}

r = -0.0072

So

A(t) = A(0)e^{-0.0072t}

It will be relatively safe for the contents to leak from the tank when 0.02% of the radioactive element remains. How long must the tank remain intact for this storage procedure to be safe?

This is t for which A(t) = 0.0002A(0). So

A(t) = A(0)e^{-0.0072t}

0.0002A(0) = A(0)e^{-0.0072t}

e^{-0.0072t} = 0.0002

\ln{e^{-0.0072t}} = \ln{0.0002}

-0.0072t = \ln{0.0002}

t = -\frac{\ln{0.0002}}{0.0072}

t = 1183

The tank must remain intact for 1183 years.
