Assuming the ratio doesn't change, you can divide any of the numbers with the previous one to find the ratio.

For example: {nl} \(150/100=1.5\) {nl} {nl} We can test this by applying this value to the other numbers in the sequence:

\(150*1.5=225\) {nl} \(225*1.5=337.5\) {nl} \(337.5*1.5=506.25\)

We have confirmed that the ratio from one number to the next is 1.5 {nl} To find the percentage we multiply a ratio with 100:

\(1.5*100=150\)

The answer is 150 %. 

WOW!   juriemagic you have won my heart.

It means the world when people show their appreciation like you just have.  

I am sure Heureka will be ever so pleased too. 

We have a fabulous team of answerers here.  

Some have extremely high skill levels, all have a great willingness to help others.

I am very proud to work along side them all. :))

This site was overhauled a couple of months ago and the new version has just never worked very well.

It is a great pity but it is still 'our' site and we are very grateful that it has been provided for us to 'play' in :))

Thanks Admin :))

CPhill has given a top answer here.  Thanks Chris   

This is Chris's graph, I have changed it just a bit and if you bounce across to Desmos using my link you will see that I have added a slider for total cost.  You can see that the cheapest orders that meet all requirements is $72,000

Melody,

I have signed up as juriemagic. Yes this site takes forever to load, and also the robot verification does not always pop up, then I have to exit, go back in, try again,, exit..and so on, until suddenly I can actually publish. Anyways, I asked you to kindly show me how you got the (x-1)(x-4) so quickly from the main sum. You did reply with a link. Thank you for that. I will check that out at some point.

Thank you for being out there and helping others, it's absolutely awesome!. Stay well.

Physics is SOOOO confusing!!!

(I've also been trying to learn some Physics today. )

Here's how to do it:

Thanks for both those great answers.

I am going to interprete it a little differently and let the alphabet go through to z

500 divided by 26 = 19 remainder 6

Only  the remainder is of any interest to us.  6 is g

My answer is not better than Heureka's, we have just that we have interpreted the question differently :))

I think this is your question.

I just copied and pasted the address.

Hi,    

Well I am glad that you joined up and I am sorry that you are having problems.

This site has a number of bugs that are still to be ironed out.  

I am, of course, very happy to help you and this was a good way to attract my attention but I don't know what you want help with.    

Keep trying to sign in but in the mean time you will have to post as  a guest but announce yourself with your potential username in the first line so that I/we know it is you.  

There are just so many questions, these days I have to ignore most of the guest questions, I don't even have time to check guest answers.  I am just concentrating (mainly) on member question and answers.

Anyway, welcome to the forum and what can I do for you?

Oh, the other mathematician that help you was  Heureka   

If 0 was in column a 1 in column b 2 in column c 3 in column d 4 in column e 5 in column f 6 in column g 7 in column a etc. in which column would 500 appear in

\(\begin{array}{|c|r|r|} \hline & n& n \pmod 7 \\ \hline a & 0 & 0\\ b & 1 & 1\\ c & 2 & 2\\ \color{red}d & 3 & \color{red}3\\ e & 4 & 4\\ f & 5 & 5\\ g & 6 & 6\\ \hline a & 7 & 0\\ b & 8 & 1\\ c & 9 & 2\\ d & 10 & 3\\ e & 11 & 4\\ f & 12 & 5\\ g & 13 & 6\\ \hline \dots &\dots & \dots \\ \color{red}d & 500 & \color{red}3 \\ \hline \end{array}\)

500 appear in d

mmm

I don't think so guest!

My response is to the previous guest answerer of the lottery ticket question.

Your question is ambiguous. If you want the formula for determining your odds of winning the first prize, then that is easy. If you selected 6 numbers out of 50, then your chances of winning the first prize are: nCr=50!/(50-6)! 6!=15,890,700. Your chances of winning the first prize are 1 in 15,890,700.

If you buy 6 tickets and there are only 50 tickets altogether then your chances of winning first prize is  6/50.

This is what you have found.

There are 50 tickets and 6 prizes, 1st, 2nd etc.

You buy 6 tickets,

What is the probability that you win all 6 prizes.

Obviously that is VERY unlikely to happen and you found the likely hood to be     1 / 15890700

Take the day number of your birthday (eg. If your birthday is 28 April, take 28). Multiply your number by 4. Add 14. Multiply the result by 25. Subtract 230. Add the month number of your birthday (ie. May = 5, November = 11) Subtract 120. Following the steps above works out your birthday. For example, if your birthday is 19 August the result of the formula is 1908. Using algebra, show how this trick works. (Hint: Let the day number = d and the month number = m)

\(\begin{array}{rcll} ( d \cdot 4 + 14 ) \cdot 25 - 230 + m - 120 \\ &=& ( d \cdot 4 + 14 ) \cdot 25 - 350 + m \\ &=& d \cdot 4\cdot 25 + 14 \cdot 25 - 350 + m \\ &=& d \cdot 100 + 350 - 350 + m \\ &=& d \cdot 100 + m \\ \end{array}\)

7:9 is proportional to 42:54 The factor of proportionality is 6.

how to find winning lottery numbers thanks. what is formula!

Your question is ambiguous. If you want the formula for determining your odds of winning the first prize, then that is easy.

(A); s= d/t (t)

and

(B): A=\pi r2 (r)

(A):

\(\begin{array}{rcll} s &=& \dfrac{d}{t} \qquad &| \qquad \cdot t \\ s\cdot t &=& d \qquad &| \qquad :s \\ t &=& \dfrac{d}{s} \\ \end{array}\)

(B):

\(\begin{array}{rcll} A &= &\pi r^2 \\ \pi r^2 &= & A \qquad &| \qquad :\pi \\ r^2 &= & \dfrac{A}{\pi} \qquad &| \qquad \sqrt{} \\ r &= & \sqrt{\dfrac{A}{\pi}} \\ \end{array}\)

Solve for x:
(4 x)/3-1/3 = x+7

(4 x)/3-1/3 = (4 x-1)/3:
(4 x-1)/3 = x+7

Multiply both sides by 3:
(3 (4 x-1))/3 = 3 (x+7)

(3 (4 x-1))/3 = 3/3×(4 x-1) = 4 x-1:
Answer: | 
| 4 x-1 = 3 (x+7)            x=22

A farmer has 212 acers of land for sale. He divides the land into 18 equal sections. About how many acers are in each section?

212/18=11 7/9 Acres in each lot.

y = -34

what is 0.00012207 as a fraction=12,207/100,000,000

{-521., -457., -11.4, -0.001403, 0.00344, 0.0344, 736., 4.65×10^7}

No Way!!!!!!!!!!!!!!!!!!!!!

y varies inversely with x. y=40 x=16

find x when y=-5

\(y\;\alpha\; \frac{1}{x}\\ y\;= \frac{k}{x}\qquad \mbox{Where k is a constant}\\ \mbox{Sub in y=40 and x=16 to find k}\\ 40=\frac{k}{16}\\ k=40*16=640\\ so\\ y=\frac{640}{x}\\ \mbox{sub in y=-5}\\ -5=\frac{640}{x}\\ -5x=640\\ x=640/-5\\ x=-128\)

y=-5 when x=-128
