Huh??     What do you want to do with them?   You collect them, and give them out to others.

They are kind of like marbles.

Here is a marble for you.  It is really one of CPhill's, but he won't mind I don't think, he has lots.

And if he wants it back maybe he could trade you for something really valuable, like points LOL

He's really very generous, I do not think he will mind at all.    

But Dakota, if the original sale price was $656.25  (as you said)

then the discount would be   $${\mathtt{0.25}}{\mathtt{\,\times\,}}{\mathtt{656.25}} = {\frac{{\mathtt{2\,625}}}{{\mathtt{16}}}} = {\mathtt{164.062\: \!5}}$$           $164.06    (to the nearest cent)

and the reduced price would be

$${\mathtt{656.25}}{\mathtt{\,-\,}}{\mathtt{164.06}} = {\mathtt{492.19}}$$

BUT the reduced price in the question was     $525   

So something seems to be incorrect  

Can you work out your error.       

Yes i know that you are new Dakota,  welcome to the forum, I hope you like it here.

Please don't mind me giving you so much direction :/

But if I don't tell you what we want you will never know.   

Wait we HAVE to include the work? I didn't know that... Im new to this website.

That is also an approximation.

$${\sqrt{{\mathtt{7}}}}$$      is  another irrational number - just like pi is.   If you try to right it as a number, the digits will go on for ever, they will not terminate or recur.  :)

Dakota, please include working because otherwise the asker cannot learn anything :)

If you write another post below this one I will give you the points :)

Dakota, the asker doesn't want to put a square number in.    

On the web2 calc you just enter   4^8

on other calcs you may enter     4  $${{\mathtt{x}}}^{{\mathtt{y}}}$$    8        

OR on newer calcs sometimes the y is just a black box.

$${{\mathtt{4}}}^{{\mathtt{8}}} = {\mathtt{65\,536}}$$

$$\frac{94+82+78+80+x}{5}>85$$

You must find the smallest x that satisfies this :)

$$\\((5^5)(8^{-5}))^{10} \\\\
=(5^5*8^{-5})^{10} \\\\
=5^{5*10}*8^{-5*10} \\\\
=5^{50}*8^{-50} \\\\$$

The Short answer is 2.64 or 3. The long answer is 2.6457513110645906.

CAN'T FIGURE OUT RIGHT ANSWER! JUST IGNORE!

Maybe this will help

Simple it's 843,624 golf b***s a day. All you need to do is take 93,736 and multiply by 9.

There should be a button that looks like

x²

y²

Then it'll immidately put in the power of 2 to the number.

He's right. You have to find the mean.

Answer: $32.67

Hi MathsGod

I do not mind you asking questions but i do not understand what your question is. 

A * sign means multiply.    :)

But yes Pi does go on forever. The digits after the decimal just keep going.

Well sort of Dakota,   

Pi is not infinite, it is a very specific number that just cannot be expressed finitely in our standard digits.

So it has an infinite number of digits,  they do not terminate of recur that is true. 

I can write pi exactly.  See here it is    $$\pi$$

Perhaps I am just being pedentic.  But mathematics is very pedentic, that is why it is so much easier then languages - at least there IS a correct answer. LOL

Technically the alphabet isn't in math. We use parts of the alphabet for variables.

Example: Solve for X,     2x-16=4

Example: Solve for A,     4a+6=4-5a

Example: Solve for H,     5h*8=65

add them all up and divide by how many numbers that there are  :)

No infinite is real and it's NOT a number, BUT it can be pi! The short-term for pi is 3.14 because pi goes on forever. We may not be able to define forever because our brains can't handle it, but there is infinite and forever. Our galaxy goes on infinitely, but my brain only thinks of our galaxy (The MilkyWay). So yes infinite is NOT a number, but many numbers, and infinite is real!

Thanks Dakota but don't forget the units.

Could you fix your answer up please ?    :))

it should be feet^2      or better still       feet²

You can superscript the 2 using the Formatting button in the ribbon above.  It is in the drop down list :)

   the angle of incidence beyond which rays of light passing through a denser medium to the surface of a less dense medium are no longer refracted but totally reflected.

   
   

   
   

   
   
   
   

It's 27ft² because to find area you need to length x height.

Formula: A=LxH

Since you have told me that you are 12 you will not understand this but I will show you.

The number of ways that 4 books can be selected from 15 is  

    $$15C4 = \frac{15!}{4!11!}$$           on the calc this is          $${\left({\frac{{\mathtt{15}}{!}}{{\mathtt{4}}{!}{\mathtt{\,\times\,}}({\mathtt{15}}{\mathtt{\,-\,}}{\mathtt{4}}){!}}}\right)} = {\mathtt{1\,365}}$$

The number of ways that  2 Lewis Carroll books can be chosen from the 5 is     5C2 =    $${\left({\frac{{\mathtt{5}}{!}}{{\mathtt{2}}{!}{\mathtt{\,\times\,}}({\mathtt{5}}{\mathtt{\,-\,}}{\mathtt{2}}){!}}}\right)} = {\mathtt{10}}$$

The number of ways the other 2 can be chosen from the other 10 books is   10C2 =    $${\left({\frac{{\mathtt{10}}{!}}{{\mathtt{2}}{!}{\mathtt{\,\times\,}}({\mathtt{10}}{\mathtt{\,-\,}}{\mathtt{2}}){!}}}\right)} = {\mathtt{45}}$$

so the number of ways that the 2 Lewis Carroll books can be chosen is  45*10 = 450

The probability of choosing exactly 2 Lewis Carroll books is     $${\frac{{\mathtt{450}}}{{\mathtt{1\,365}}}} = {\frac{{\mathtt{30}}}{{\mathtt{91}}}} = {\mathtt{0.329\: \!670\: \!329\: \!670\: \!329\: \!7}}$$

so the answer is     $${\frac{{\mathtt{30}}}{{\mathtt{91}}}}$$
