Thanks Rom,   

RainbowPanda, maybe it will help you understand what Rom has  said if I tell you this:

A monomial is an eqpression with only one term.    Like   5x   or   -3y^2   

Product means multiply.

So you are just looking for 2 things that multiply together to make  \( -84a^6b^{10} \)     there are lots and lots of correct answers.

Rom has introduced all those c's and m's.  They are just numbers.  You have to use numbers that work. Rom is not suggesting that you leave them as c's and m's     

Good work RainbowPanda   

Mmm  sounds like either the question or the answer is wrong.

Certainly 3/8 of a second of arc does equal 0.00010416667 degrees.

   But is that really what was meant?

The red ones are above and the blue ones are below and you can finish it.

Thanks Mellie,

I hope we see a lot of you and I know that I am not the only one who hopes so.   :)

There is not enough information but I can tell you the maximum number on the shelf that could be sodium free.

This would be correct if ALL the cans on the shelf are vegetarian.

720-170-40 = 500

Rom has given you a hint, he has not answered your question as you should be able to take his hint and answer the question yourself.

I'll give you some more hints.

What is the gradient of     5x+8y=-9     ?

You may need to rearrange it and put it in the form     y=mx+b   where m is the gradient and b is the y intercept.

There are other ways to do it but this is the one most taught.

Then follow Roms hint.     i.e   The gradient of the other line is the negative recoprocal of the one you have.

If you cannot at least find the gradient of the line then you are not ready to answer this question.

And we are here to help you learn not to supply you with a cheat answer.

There are only 5    5 digit palindromes in base 2. They are

10001 base 2 which equals   17 base 10

10101  base 2 which equals   21 base 10

11011  base 2 which equals    27  base 10

11111  base 2 which equals     31  base 10

Which of these can be expressed as a palindrome in any base?   Let the base be x

which is of the form   ax^2+bx+a   (base 10)

                 where    a b and x are all  integers 

                 and a and b are both smaller than x

x=2 is too small

x=3, a=2       9a+b+a  =   10a+b  = 20+1  works        212 (base3) = 10101 (base2) = 21 (base 10)

So the question becomes... can I make 17 with a 3 digit palindrome.

101 base 4     That is obvious I should have seen it in the first place

\(10001_2=17_{10}=101_4\)

So the answer is  10001

Yea that might be a better plan but if they are rescued soon then maybe Gilligan will be enough. 

Actually i'd chose one of the others. Maybe Thursten Howell III  or his wife?

Then again there are plenty of coconuts in those cocnut palms and also plenty of fish in the sea so maybe it is better that they don't eat anyone.   

For those who don't know what we are talking about. I know it is before most people's time :)

Thanks Alan :)
