@amWhy How about now? Still female?

Euler 2

My gender is hard to guess

Never gonna tell my gender

Never gonna tell my name

Never gonna tell my location

And reveal my identity online

@Euler2 no need to, we don't need it and someone who might will find a way to it smoothly:xD

Hello!

Can I ask about this question? I don't know how to answer this, so embarrassing...

The time it takes for A and B working together to paint a house is 2/3 the time it takes for B to finish painting a house alone. If A takes six hours to finish painting a house alone, how long does B take to do the same thing?

Why. Why is it that I can solve some calculus questions but not this one. Just why.

@XanderHenderson , if I may ask?

Srijan M.T

10:56

@soupless I hope it is 2/3rd time of B in hrs

@soupless What’s the answer

I get the answer in terms of iota

epsilon-emperor

Thanks for answering, @TeresaLisbon! As promised, I have started a bounty to award your answer but I think I can award it only after a day (not sure how that works). Anyway, thanks for being so helpful - I understand the theorem better now!

soupless

11:31

@SrijanM.T I got the correct answer, somehow. Wow. It is 3 hours

But how? A miracle.

Teresa Lisbon

11:44

@epsilon-emperor It was a pleasure helping you out, once again!

Srijan M.T

@soupless How ?

I did this: 1/6 + 1/B = 3/2(B)

@soupless You have tell me how. It’s a good Q

Srijan M.T

12:06

@TeresaLisbon it’s true ma’am .Men have the privilege to walk at night but not women. Women’s are other ones who give birth and take the pain.

Also , I think that you have done materialistic engineering.

@TeresaLisbon I think its completely fine. We should be able to do whatever we want

Teresa Lisbon

12:45

@SrijanM.T I didn't get the meaning of that part? I have done only mathematics, although yes I've seen the "basics" of material science.

Srijan M.T

@TeresaLisbon I saw your profile of Stanford I guess

Some material engineering I guess it showed

I think it was yours

Teresa Lisbon

@SrijanM.T I see! Aha, nope I've been doing just math for ages. Just math. I'm not Teresa. She is someone I aspire to be.

Srijan M.T

@TeresaLisbon I have seen mentalist. I know who she is

You were smiling in that profile with blue shirt. Maybe I am wrong too.

Teresa Lisbon

@SrijanM.T Oh I see. Nope, I am very much in India, I've done all my work in India bar a 20 day workshop in Moscow, where I still managed to pull something out of the hat. Also I don't think that person is me, who you are looking at.

Srijan M.T

Yeah.

So , what do you wish to achieve in maths ? Like Is to go in artificial intelligence, computer science

Or sth else

Where are you going to apply it’s application of the study you are currently doing

Teresa Lisbon

13:02

@SrijanM.T Currently a PhD, looking forward to becoming a professor after a few years!

Paramanand Singh

@soupless: that was a nice arithmetic question. The key to figure out how much work a person does in one unit of time.

Srijan M.T

@ParamanandSingh Yes. I did the same thing

I did this: 1/6 + 1/B = 3/2(B)

But getting wrong answer

Teresa Lisbon

1/6 + 1/B = 3/2(B) --> 1/6 + 2/(2B) = 3/(2B) --> 1/6 = 3/(2B) - 2/(2B) = 1/(2B) --> 2B = 6 --> B=3

Paramanand Singh

This gives $B=3$

Srijan M.T

Hmm. Right. I got of iota somehow

Paramanand Singh

13:13

A lot of such questions on arithmetic are usually asked in the competition for government jobs

Srijan M.T

@TeresaLisbon Ohk. B is with Denominator

soupless

Sorry, I just joined.

Srijan M.T

@soupless I had been waiting for you bro.😅. Did you do the same method I did ?

soupless

@SrijanM.T This was my solution.

Let $a$ and $b$ be the number of working hours for persons A and B, respectively. Then, $$\frac{1}{a + b} = \frac{2}{3}\left(\frac{1}{b}\right)$$

Srijan M.T

Can you explain it a bit. Why 1/b

And how 1/a+b

soupless

13:20

The left-hand side is the number of hours A and B worked to finish painting a house, hence the 1 in the numerator and $a + b$ in the denominator

Srijan M.T

Ohk

soupless

You should get the right-hand side at this point

Srijan M.T

Hmm k

Similar method right

soupless

Then, it is given that $1/a = 6$, hence $a = 1/6$. Solving for $b$,
\begin{align*}\frac{1}{\frac{1}{6} + b} &= \frac{2}{3b} \\ \frac{6}{6b + 1} &= \frac{2}{3b} \end{align*}

Wait, something's wrong. I can feel it

Oh, it's fine. Continuing,

Srijan M.T

Ohk. I got it. Btw , I’m on tablet. So , I don’t need mathjax. It doesn’t translate the latex on chats

soupless

13:25

\begin{align*}9b &= 6b + 1 \\ 3b &= 1 \\ b &= \frac{1}{3} \\ \frac{1}{b} &= 3\end{align*}

Therefore, $B$ spent 3 hours working to finish painting a house.

@SrijanM.T Oh. I use the full site and robjohn's bookmarklet to render them

Srijan M.T

Whats bookmarklet

Btw , I also derived that ideal gas equation. It is amazing the way it is done.We use momentum conservation as the main principle and that molecule only travel parallel

soupless

@SrijanM.T Sorry, I don't know either. I just picked it up somewhere and just used it.

Euler 2

@SrijanM.T A bookmarklet is a bookmark st'r'd in a web brows'r yond enwheels javascript hests yond addeth new features to the browser

Srijan M.T

@Euler2 Ohk.

@soupless So , how you use it

Euler 2

Are you writing in old English ?

soupless

I just used it when I stated it to you. Here

Srijan M.T

Ohk

@SrijanM.T yea

I bethink this is much bett'r

Koro

15:24

Madam, How are you? I hope everything is going well. @TeresaLisbon

Can you please explain to me how to formalize cartesian product of a line with a circle

Anthony

@Euler2 does this by any chance mean "'p"?

Koro

I understand that it will be a cylinder with never ending axis and that is because my intuition says so

@TeresaLisbon

Euler 2

@Anthony no

Anthony

what does it mean

@Euler2

Euler 2

Decode it yourself :)

soupless

15:31

It seems that '158 118 246 22 46 118 134 4 38 150 14 174 46 202' are in base 8

Euler 2

No @soupless

Anthony

@soupless if it were that easy, i wouldn't be asking for hint:xD

damn it, i tried, couldn't
tell me now

soupless

@Anthony What if @Euler2 made it so that we would not think that it is in base 8 but it really is not

Koro

I tried with the simplest case: Let L be a straight line and $C$ be a circle of radius 1. Then L={((0,a): a \in \mathbb R }, C={(x,y): x^2+y^2=1 } and $L\times R={((0,a),(x,y)): a\in R and x^2+y^2=1 }$. I don't understand how to deduce that it's a cylinder from here. @TeresaLisbon

@soupless well, he has a habit of putting some bad messaged in coded ways, i guess that's what cowards do:P

Hey wait yes I am a coward

@soupless it means stupid people

The students were terrified of the teachers because _they_ always consider themselves to be on the right side. _They_ is referring to which of the following?
a) students
b) teachers
