Anonymous (the first one), even though your first answer is wrong (the beginning was right, then it got kinda ugly), I think you deserve a brownie (Sorry, all my cookies are gone, but I think brownies taste good as well) for the two other ones, and around 13.5/20 (Sorry, I cannot put thirds of points but only halves, so I round the the next half point above).

As for you Cphill, the first answer is actually 288. So you also deserve a brownie for your answer (but no mark since you gave only one answer) :

MaiaMitchell and Anonymous (the second one), you were right when you told me that "Anonymous 1"'s 1st answer was right, anyway, you didn't gave me any answer. But that's OK, you might deserve each a sweet fot your remark.

Anonymous, (the third one), I am sure that it isn't 2 since I checked the answer with 3 calculators (including Google calculator):

They all answered 288, never 243, let alone 2. Check it if you have any doubts.

31 x 0.48  =  14.88 (rounded to 15 pounds)

This can be approximated:  0.48 pounds is about 1/2 pound

1/2 of 31 students is 15.5 pounds; 15 would be enough, but buying 16 would allow for spilling. 

or/ also   101,700 seconds

I would add   3  and 16 to that list

1.05301899  =   1   5,301,899/100,000,000    or    105,301,899/100,000,000

2 * 6    +   3 * 8  =  36   is one way

Wait, what is the wrap made out of. I like lunch wraps with lettuce, tomatoes, pickles, and a little meat sometimes. Breakfast wraps are just gross. Which brings me to my next point: Mcmuffins are disgusting. I sometimes wonder who the h**l came up with it, it's not even a muffin. C'mon america you don't chow down on that s**t. I once was kidnapped by purple pepperoni pirates, I had quite the adventure. My nostrils sometimes whisper to me, they tell me to burn, they tell me to k**l. Should I listen to my nose?

No, no, purple pirates wear hats made of pepperoni. So therefore your theory is wrong.

Well, first, you do the hokey pokey than you turn yourself around...

That outta help. :D

5992294 + 6031049 + 5948791 + 5965926 + 5997854 + 6047594 + 5928127 + 5989570 = 47901205

If you mean  this :   -25/8 - 400  ... we have    -3.125  - 400  = -403.125

If you mean this :  -25/ (8 - 400)  ... we have   -25/-392 = about .0638 

I want to play with this one, too

[x^2 -7x + 6] / [x^2 - 8x + 12]  > 0    factor top and bottom

[(x - 6) (x - 1)] / [ (x - 6) ( x - 2) ]  > 0   Note that this simplifies to :

(x - 1) / ( (x - 2)  > 0      however, we have to be aware that our grpah will have a "hole" at  x = 6

The intervals of interest are (-∞, 1) (1, 2) (2, ∞ )

If you check, the two "outside" intervals make the equation the original eqaution true....again, we have to be aware that the last interval will have the "hole" where x = 6......here's the graph.....

f(x) = x^2  .....   so f(2)  = (2)^2  = 4

I assume that the original cost was $40.96  and the final cost was $ 18.62...the percent discount [on the original cost] is given by :

[Original Cost - Final Cost] / [Original Cost ]  x 100%    so we have

[40.96 - 18.62] / [ 40.96 ] = .5454 x 100% =  54.54%

3 9 10 1 to make 8

10 - √9/3 - 1 =

10 - 3/3 - 1  =

10 - 1  - 1  =

8

--------------------------------------------------------------------------------------------------------------------

Also

(10 - 9 + 1)³ =

(1 + 1)³  =

(2)³ =

8

 $$\small$\text{
Solve for x : $\log_9{(x^2)}=9$

$$\small{\text{Formula: $\boxed{~ \log_b{(b^a)}=a~}$}}\\\\
\small{\text{
We have $b=9$, and $a = 9$ so $\log_9{(9^9)}=9$, but $9^9$ is $x^2$

\small{\text{$
\begin{array}{rcl}
x^2 &=& 9^9\\
x &=& 9^{\frac{9}{2}}\\
x &=& \left(\sqrt{9} \right)^9\\
x &=& \left(\sqrt{3^2} \right)^9\\
x &=& 3^9\\
\mathbf{x} & \mathbf{=} & \mathbf{19683}\\
\\

\\
\end{array}
$}}\\$$

Because I am not as clever as you   

$$\\log_9x^2=9\\\\
2log_9x=9\\\\
log_9x=9/2\\\\
9^{log_9x}=9^{9/2}\\\\
x=9^{9/2}\\\\
x=3^9\\\\
x=19683$$

check:

$${{log}}_{{\mathtt{9}}}{\left({{\mathtt{19\,683}}}^{{\mathtt{2}}}\right)} = {\mathtt{9}}$$
