What is the volume of the prison below?

ioda

Answer:

3 1/2

Step-by-step explanation:

To find the volume of a rectangular prism, you multiply l*w*h.

We just have to multiply 1 3/4 by 2!

*This is because the 1 doesn't give you anything.*

That equals 3 1/2!

The radioactive isotope of lead, Pb-209, decays at a rate proportional to the amount present at time t and has a half-life of 3.

blagie [28]

Answer:

$N(t) =N_o (\frac{1}{2})^{\frac{t}{t_{1/2}}}$

Where $t_{1/2}= 3.3 hr$ represent the half life and the intial amount would be $N_o = 1$

And we want to find the time in order to have a 95% of decay so we can set up the following equation:

$0.05 = 1 (0.5)^{t/3.3}$

If we apply natural log on both sides we got:

$ln(0.05) = \frac{t}{3.3} ln (0.5)$

And solving for t we got:

$t= 3.3 *\frac{ln(0.05)}{ln(0.5)}= 14.26$

So then would takes about 14.26 hours in order to have 95% of the lead to decay

Step-by-step explanation:

For this case we can define the variable of interest amount of Pb209 and for the half life would be given:

$N(t) =N_o (\frac{1}{2})^{\frac{t}{t_{1/2}}}$

Where $t_{1/2}= 3.3 hr$ represent the half life and the intial amount would be $N_o = 1$

And we want to find the time in order to have a 95% of decay so we can set up the following equation:

$0.05 = 1 (0.5)^{t/3.3}$

If we apply natural log on both sides we got:

$ln(0.05) = \frac{t}{3.3} ln (0.5)$

And solving for t we got:

$t= 3.3 *\frac{ln(0.05)}{ln(0.5)}= 14.26$

So then would takes about 14.26 hours in order to have 95% of the lead to decay

How many positive integers between 100 and 999 inclusive are divisible by three or four?

Gnoma [55]

999 - 100 + 1 = 900
There are 900 numbers between 100 and 999 (inclusive)

We group the numbers into groups of 3s. So we find one number divisible by 3 in every group.
Number of numbers that can be divided by 3 = 900 ÷ 3 = 300
Number of numbers that can be divided by 3 = 300

We group the numbers into groups of 4s. So we find one number divisible by 4 in every group.
Number of numbers that can divided by 4 = 900 ÷ 4 = 225
Number of numbers that can divided by 4 = 225
Among the group of 4s, there is 1/3 that are already inclusive in divisible by 3.
225 ÷ 3 = 75
Number of numbers that can divided by 4 = 225 - 75 = 150

Total numbers of positive integers divisible by three and fours = 300 + 150 = 450

Which of the following retirement plans places a maximum amount that an individual can contribute to the fund in a given year at

Andreyy89

$\boxed{{\text{IRA}}\left( {{\text{Individual Retirement Account}}} \right)}$ places a maximum amount that an individual can contribute to the fund in a given year at $\$5000$ . Option (d) is correct.

Further Explanation:

Given:

The options are as follows,

(a). 401(k)

(b). Tax Deferred Annuity

(c). Pension

(d). IRA

Explanation:

${\text{401}}\left( {\text{k}} \right)$ is a retirement plan that permits employees of a firm to invest in their retirement. This type of retirement is tax deferred.

Tax-deferred annuity is a type of investment used by employees in planning their retirement. In this type of retirement the annuity matures tax-free till the age of retirement.

Pension is a series of payments made after retirement.

${\text{IRA}}\left( {{\text{Individual Retirement Account}}} \right)$ is a tax deferred individual retirement plan.

$\boxed{{\text{IRA}}\left( {{\text{Individual Retirement Account}}} \right)}$ places a maximum amount that an individual can contribute to the fund in a given year at $\$5000$ . Option (d) is correct.

Option (a) is not correct.

Option (b) is not correct.

Option (c) is not correct.
