The relation of 10 squares to 100 squares can be expressed in many ways. Which of the following is not a way to express the rela
irakobra [83]

Answer:

As there are no options given in the question, but the options in the complete question are;

a) 2/10b) 20%c) 0.02d) 0.2

So, from the given options "c" is not a way to express this.

we can write 20/100 as 2/10 so option a is a way to express given relationship. and if we look at option b, it is also a way to express 20 from 100 is 20%. And if we divide, we get 20/100 = 2/10 = 0.2, so d is also a way to express given relationship. Thus, c is the answer.

Step-by-step explanation:As there are no options given in the question, but the options in the complete question are;

a) 2/10b) 20%c) 0.02d) 0.2

So, from the given options "c" is not a way to express this.

Problem PageQuestion The mass of a radioactive substance follows a continuous exponential decay model, with a decay rate paramet
asambeis [7]

Answer:

<em>t = 1.51</em>

Step-by-step explanation:

<u>Exponential Model</u>

The exponential model is often used to simulate the behavior of a magnitude that either grow or decay in proportion to the existing amount of that magnitude.

The model can be expressed as

M=M_oe^{kt}

In this case, Mo is the initial mass of the radioactive substance and k is a constant which value is positive if the mass is growing or negative if the mass is decaying.

The value of k is not precisely given in the question, we are assuming k=-0.2

The model is now

M=M_oe^{-0.2t}

We are required to compute the time it takes the mass to reach one-half of its initial value:

\displaystyle \frac{M_o}{2}=M_oe^{-0.2t}

Simplifying

\displaystyle \frac{1}{2}=e^{-0.2t}

Taking logarithms

\displaystyle ln\frac{1}{2}=ln(e^{-0.2t})=-0.2t

Solving for t

\displaystyle t=-\frac{ln\frac{1}{2}}{0.2}=1.51
