10 cents, because 25%=1/4, therefore 40/4=10

=3x^2+11x+6

I befriended a very friendly wolf and he really likes me. I decided to take him home to live with me and be my hunting companion. Before I had my wolf-dog, Wolfie, I used to bring back home approximately h pounds of meat from hunting in the forest. Now that Wolfie is with me, the ratio of how much meat I brought home before I found Wolfie to after I found him is m:b. I almost always eat approximately 1/8 of the meat we bring home now. Wolfie eats about w of what I eat out of the rest of the meat that we have. We eat 3 meals a day of about the same amounts. Each pound of meat we have left over is sold to merchants for (on average) for $d. How much money do we get selling the meat we have left over daily now that I have Wolfie?

The amount of meat now brought home is h(b/m)lbs. = (hb/m)lbs.

The amount consumed by you is (1/8) of this =[hb/(8m)] lbs. ...so there's (7/8)(hb/m) lbs. left

And Wolfie consumes w of what you eat...and "of" means "multiply".... so he eats → w[hb/(8m)]lbs

So, the amount left over is (7/8)(hb/m) - (1/8)(w)(hb/m) = [(hb)/(8m)](7 - w)lbs

So....the amount of money you make is just what you're paid per pound times the number of lbs. left over =

$(d)[(hb)/(8m)](7 - w)

{The 3 meals per day is a "red herring" ....an irrelevant fact.....}

Hi all,

It hasn't been super busy but there have been some good answers from Alan, SevenUp, CPhill, Nauseated, Aliaslanturk, gliu1, Beray, Heureka and Muhum.  Thanks all.   :)

I'll just factorise it.   

$$\\5(x^2+3)^4(2x)(x-2)^4+(x^2+3)^5(4)(x-2)^3\\\\
10x(x^2+3)^4(x-2)^4+4(x^2+3)^5(x-2)^3\\\\
2(x-2)^3(x^2+3)^4\;\;[5x(x-2)+2(x^2+3)]\\\\
2(x-2)^3(x^2+3)^4\;\;[5x^2-10x+2x^2+6]\\\\
2(x-2)^3(x^2+3)^4\;\;[7x^2-10x+6]\\\\$$

hi,

We are not here to do all your homework for you.

Which one don't you understand ?

I don't understand.  What is a natural position? 

100%-60%=40%

40% of $1.10 = 44c

$${\frac{{\mathtt{40}}}{{\mathtt{100}}}}{\mathtt{\,\times\,}}{\mathtt{1.1}} = {\frac{{\mathtt{11}}}{{\mathtt{25}}}} = {\mathtt{0.44}}$$

I have never heard of this before......thanks, heureka....!!!

I quite likely made a mistake but I got

$$db\left(\frac{5-3w}{8}\right)\;\; dollars$$

Let A be the the probability that she is a dancer = 54/80  = 27/40

Let B be the probability that she is a singer = 35/80 = 7/16

And the probability of A and B = (A ∩ B) = 9/80

So the probability of B, given A, is just

P(B l A ) = P ( A ∩ B) / P(A) = (9/80) /(27/40) = (9/80)(40/27)  =(1/2)(1/3) = 1/6

This makes sense....there are 54 dancers and 9 of them sing, as well. So...9/54 = 1/6

What does the ! mean ?

The subfactorial or left factorial, written, is the number of ways that n objects can be arranged where no object appears in its natural position (known as "derangements.")

The formula:

$$\begin{array}
$
!n = n! \cdot \displaystyle\sum^{n}_{i = 0} \frac{(-1)^i}{i!}
=n!\cdot\left(1-\frac{1}{1!}+\frac{1}{2!}-\frac{1}{3!}+\cdots +(-1)^n \ \frac{1}{n!}
\right)$
\end{array}$$

Example !6:

$$\begin{array}
$
!6 = 6!\cdot\left(1-\dfrac{1}{1!}+\dfrac{1}{2!} -\dfrac{1}{3!} +\dfrac{1}{4!} -\dfrac{1}{5!} + \dfrac{1}{6!} \right)= 265
$
\end{array}$$

Example !7:

$$\small{\text{$
\begin{array}{rcl}
!7 &=& 7! * \left(1-\dfrac{1}{1!}+\dfrac{1}{2!}-\dfrac{1}{3!}+\dfrac{1}{4!}-\dfrac{1}{5!}+\dfrac{1}{6!}-\dfrac{1}{7!}\right)\\\\
&=& 5040*\left(\not{1}-\not{1}+\frac{1}{2}-\frac{1}{6}+\frac{1}{24}-\frac{1}{120}+\frac{1}{720}-\frac{1}{5040}\right) \\\\
&=& \frac{5040}{2}-\frac{5040}{6}+\frac{5040}{24}-\frac{5040}{120}+\frac{5040}{720}-\frac{5040}{5040}\\\\
&=& 2520-840+210-42+7-1\\\\
&=&1854
\end{array}$}}$$

Maybe this unit will help?

$$\sqrt{x}-16$$     

This cannot be simplifed,

You logic is good but it is not 9 years so anon will have to adjust the answer a little :)

2x^3+8x^2+3x-6

$$2x^3+8x^2+3x-6$$

Are you sure all the signs are correct?

80-54-35=-9

so

80 children,    45 dance only,   26 sing only,    9 dance and sing

P(S|D)= 9/54 = 1/6

Yes, if you can tolerate Nauseated, then this site is safe.

If you private message people in any forum you do have to be a little on guard but if you are sensible and don't give out personal information like your address or phone number you can learn a lot and have a lot of fun on this innocent little site.

Now for the big stick.  Please do not post on my wrap!    LOL

..........Besides all that....our CRAPCULATOR is now fully fuctional, too.....well.....almost......we had to get rid of a few "bugs".......not to mention some assorted ant-lions and spiders and trolls.....(oh my !!!!....)

That's brilliant Geno, I never would have thought of that.  

3x/2 - 6 < 9     add 6 to both sides

3x/2 < 15        multiply both sides by

3x < 30           divide both sides by 3

x < 10

Here’s a post that will start you on your quest for answers.
