Now im confused chris...

The awnser is 5, 5 & -5 cancel * 2    5+5+5=15    15-10=5

2 the answer you want can be figured out by your fingers

You may recall your teacher talking about tenths, hundreths etc. in decimals like this: T H Th

                                                                                                                            0.123

This was because who can now easily convert these decimals into fractions. For instance, if the number is 0.2, then you can see that there is a 2 in the tenths section which therefore makes it two over 10 or 2/10.        

$${\mathtt{78.35}}{\mathtt{\,\times\,}}{\mathtt{10}}\% = {\mathtt{7.835}}$$

Did you put that exclamation mark there Andre?  Thank you!  

Let original price = x

sale price = (1-0.23)x = 0.77x

So 0.77x = $485.87

So x = $485.87/0.77 = $631

I think the answer you are looking for is two.

Now the reply and edit functions are starting to play up.

On one question I had to press reply 3 times before I was taken to the correct page. ( I had to use the return to last page twice)

Just then I tried twice to edit my last message.  I was going to add that last comment there.  I tried twice.  I was taken to the right page but the whole original question was not there.  Half of it was missing.

I'd like to check out the new 'ask a question' and join proceedures for new people but I can't unless I log out first.  I haven't done that because i am worried that I won't be able to log back on.  I am not sure that i know my password.  Kitty<3 and CPhill have already had to take on new identities.  I don't want to be the next 'batman'.

1n 1996 there are 

80 + 16% of 80 = 80 + 0.16*80 = 80+12.8 = 92.8

This can also be done as follows

116% of 80 = 1.16*80 = 92.8

You can round this off and say there will be about 93 rabbits in 1996.  But if you use this answer for the next year, use the full non-rounded answer.

The next year there will be

92.8*1.16=107.648 which can be rounded to 108 rabbits for 1997.

but remember 92.8 was the answer to 80*1.16

so in 1997 (which is the second year since the beginning) 

rabbits = 80*1.16*1.16 = 80*1.16²=  107.648

rabbits in the 3rd year (which is 1998) will be 80*1.16³

etc

Undefined

To see why this is so, consider that 6 /2 = 3

Why?? Because multiplying 3 times the denominator in the fraction (2) gives me the numerator (6)

But what if we have 3 / 0 ??

What can I multiply 0 by to get  3 ??

Answer ....  nothing

There is one more special case.... 0 / 0

This is known as an "indeterminate form'

To see why, note that 0 / 0 could equal anything, because multiplying anything by the denominator, (0), would give us the numerator (0).....thus, we can't "determine" what 0 /0 might be equal to !!!

Hope that helps !!!

The answer is "Error"

Hello,

I am the Sponge Bob's neighbour and I work at the Krusty Krab. This is my sponge friend

Gib

OK....that was somewhat better.....I hope you understood it !!!

  Let me try this again !!! (There is no "preview," so I can't tell what might happen!!)

          2x^2 + x - 8

            __________________   

     x - 1 ) 2x^3 - x^2- 9x+18

               2x*3 - 2x^2

         _________________

                     x^2 - 9x

                     x^2 -   x

                     _________

                              -8x + 18

                              -8x + 8

                              _______

                                       10

So we have

(2x^3 - x^2- 9x+18) \ (x-1)

Let's do some "long division" on this one...we have

        2x^2 + x - 8

        __________________x - 1 ) 2x^3 - x^2- 9x+18

          2x*3 - 2x^2

         _________________

                     x^2 - 9x

                     x^2 -   x

                     _________

                              -8x + 18

                              -8x + 8

                              _______

                                       10

So we have   

2x^2 + x - 8 with a "remainder" of 10 / (x-1)

P.S.......I don't if this is gonna' line up correctly on this new website, but I did my best !!!

Thank you very much

enter your number 1.145 into the calculator input field and press "enter" or the "=" button

Evaluate the following expression for a = -5 and b = 7

a2 – 6b

Mmmmm....let's look at this again

We have

(-5)*2 - 6*(7) =

-10 - 42  =  -52

it looks like this ÷

So this hexagon consists of 6 equilateral triangles where the area of each triangle = 1/2 * 5 * 5 * √(3)/2 =

25√(3)/4. So multiplying this by 6, we get

6 *(25√(3)/4) = 3*(25√(3)/2 = 75√(3)/2 square units
