3/8
1/4 becomes 2/8 to be equal so he used up 2/8
3/8 + 2/8 = 5/8 + 1/8 = 6/8 + (insert birdhouse here) 8/8 / 1 
3/8 - 2/8 = 1/8 - 1/8 = 0/8 + (insert birdhouse here) 2/8

Mr. Rivas used  \frac{2}{8} of the paint for the birdhouse.

<h3></h3><h3>Further Explanation</h3>

<u>Given:</u>

Paint used for bookshelf = \frac{3}{8}

Paint used for a wagon = \frac{1}{4}

Paint used for a birdhouse = x

amount of paint left = \frac{1}{8}

<u>Question:</u>

How much paint did he use for the birdhouse?

Total paint Mr Rivas bought is 1 can of paint, so we can write the equation as below:

\boxed {\frac{3}{8} + \frac{1}{4} + \frac{1}{8} + x = 1 }\\

Because those fractions has different denominator, so we need to find the common denominator for 4 and 8, and that would be 8. So, the equation will be:

\boxed {\frac{3}{8} + \frac{2}{8}  + \frac{1}{8} + x = 1 }\\\boxed {\frac{6}{8} + x = 1 }\\\boxed {x = 1 - \frac{6}{8} = \frac{8}{8}- \frac{6}{8}  = \frac{2}{8}  }

So, Mr. Rivas used  \frac{2}{8} of the paint for the birdhouse.

Karen wants to invest $750 per quarter for a period of 25 years in order to accumulate a value of $120,000. What minimum annual
Anika [276]

Answer:

Step-by-step explanation:

For Compound Interest with continuous deposit,

We have that:

\frac{dS}{dt}=rS+k

\frac{dS}{dt}-rS=k

Using Integrating factor: e^{\int\ {-r} \, dt }=e^{-rt}

\frac{dS}{dt}e^{-rt}=ke^{-rt}

Taking Integrals from 0 to t

Se^{-rt}=\frac{k}{-r}e^{-rt}+C\\S=\frac{k}{-r}+Ce^{rt}\\When t=0\\C=S_{0}+\frac{k}{r}

Now substituting back C

We have:

Se^{-rt}=\frac{k}{-r}e^{-rt}+S_{0}+\frac{k}{r}\\S(t)=S_{0}e^{rt}+\frac{k}{r}-\frac{k}{r}e^{rt}\\S(t)=S_{0}e^{rt}+\frac{k}{r}(1-e^{rt})

Se^{-rt}=\frac{k}{-r}e^{-rt}+S_{0}+\frac{k}{r}\\S(t)=S_{0}e^{rt}+\frac{k}{r}-\frac{k}{r}e^{rt}\\S(t)=S_{0}e^{rt}+\frac{k}{r}(1-e^{rt})

If initial deposit =$750, Continuous Deposit = 750, t= 4X 25 years=100

S(t)=S_{0}e^{rt}+\frac{k}{r}(1-e^{rt})\\120000=750e^{100r}+\frac{750}{r}(1-e^{100r})\\160=e^{100r}+\frac{750}{r}-\frac{750}{r}e^{100r}\\
