Hadampson:
A student walk 3km at a speed of vkm/hr.. Find the time taken, in the form of v?? Plz help me solve dis word problem, maths guruz!

jackpot:
fine. Hope you're good?

Karmanaut:
Yes, boss. There's no series solution.

Hadampson:
Tanx Karmanaut... D questn z nt complete. Dis is d final questn on dat word problem.. If d time taken for student to walk =35mins... Find d value of v?

Hadampson:
A boy walks 8km at vkm/hr. He then cycles 15km at 2vkm/hr. In terms of v, write down the time taken in hours (a) when walking (b) when cycling (c) if the total time for the journey is 2hr 35mins, find the boy's walking speed..

Hadampson:
Plz maths guruz in da house. I want to ask a question? D question is where can a mathematics graduate. Am tired of hearing that a mathematics graduate can work anywhere, anywhere as how?

oh..i see. ..

n u didn't reply my mail sir, what i do ?

Karmanaut:
Turns out it had a series expansion. Maths Chic wrote the answer.
Getting to that, cheers.

Let me take on this question. I will try to skip the part you do not want to hear: "mathematicians can work anywhere"(even if my trajectory of arguments will spiral through that path).
In our present society mathematics plays an important role in the development of science and technology. This spans over several fields like {medicine, epidemiology, engineering, finance etc}. I usually do not divulge information, but for this question let me make an exception. My second degree was in mathematical modelling in the u.k. Mathematical modelling is the process of capturing real life process into mathematical framework, solving it in the context of using mathematical techniques hence gaining insight to real life process. Let me give you an example for instance if there is an outbreak of a disease, what are the strategies one can implement to try to curb the spread of the disease. should infected people be isolated? the effect of implementing an awareness program? will treatment of the infected people suffice? what is the asymptotic behavior of the disease? . Now these questions can only be answered by knowing the nature of the disease, basic reproduction number(a measure of how the disease spreads) and the asymptotic behavior of the equilibrium states. That's when you hear of the SIR models and so on.
My current work is on Physiology. trying to formulate mathematical model to describe the transport mechanism of the lymphatic vascular system. We hear of elephantiasis(the swelling of the limbs) this as a result of the failure of the lymphatic system. There is no cure for it and one of the problem is that no one adequately understand the transport mechanism. Now this means i have to understand the physiology of the lymphatics to make rational assumptions for my model. So you you see you are covering two sides: i.e. it must make both physiological sense as well mathematical sense.
Also in finance you cannot undermine the power of mathematics. Sorry for the deviation, my aim is for you to see the application of mathematics in your every day life. Having said that, you should know that there is a huge difference between learning mathematics and knowing when to apply them. The problem with our educational sector is that they don't teach us how to think , they just give equations you learn how to solve, or memorize the theorems, go into the exam hall and reproduce it and you get a first class. But when you go to a top tier school in the western world and meet your contemporaries then you realize your weaknesses (don't worry this was exactly what happened to me). My advice to you is for you to keep pushing yourself, and please don't hesitate to learn programs this is very necessary.
Conclusively you can be of immense value to any firm spanning from Finance, medical, Engineering sector. Most firms look for analytical and quantitative minded individuals. I have seen many bright minds in this forum who just need the right guidance. Any one who wants to perhaps go into mathematical biology should contact people like Abba Gumel (i have met him once and he is highly prolific and a named Professor at Arizona state university) or Daniel Okuonghae (got his M.Sc in mathematical modelling from Oxford University presently in Uniben). These are people who will guide you into the trajectory of value in the context of application of mathematics.

May 19 jst a blunt guess

Madmathecian:
Think through it.

MathsChic:
This is more of a puzzle than it is a maths problem. And some fundamental assumptions must be made in order to move forward.
If Cheryl told Albert and Bernard the month and date separately, then she only could have told Albert any of the set (May, June, July, August) and Bernard any of the set (14, 15, 16, 17, 18, 19).

From the first sentence, Albert claims "I don't know what Cheryl's birthday is, but I know that Bernard doesn't know too". Since Bernard doesn't know too and only knows the date, then the date can't be (18,19), merely because if it were any of the two then Bernard would know for sure what Cheryl's bday is. 18 or 19 would simply mean June 18 or May 19.
So, set of possible values Cheryl could have told Bernard is (14, 15, 16, 17). Albert's conclusion is based on a blanket assumption that Bernard is able to figure this out. Not so good. Albert would also have been told July or August for him to be convinced Bernard doesn't know Cheryl's bday, because if he was told May or June he would have doubts about whether Bernard knows or not.

From the second sentence, Bernard claims "at first, i didn't know what Cheryl's birthday is, but now i know". This can only mean that Bernard has figured out that Albert has only July & August as months. Since he couldn't have had May or June which would have given away the answer long before. But since Bernard has a date already, it means he now knows Cheryl's bday as July 16, the only possible cross between the two available sets. It couldn't have been July or Aug 14, as Bernard then would still not have known what Cheryl's bday is.

From third sentence, Albert now knows Cheryl's bday too, because he has the month. He didnt have the day, but July 16 is the only date he could have, as Aug 15 or 17 would mean he still doesn't know what the bday is.

So, answer is July 16. But seriously, you are the only one doing the thinking here, not Albert or Bernard. I don't think this is a clear puzzle.

Solve for (9!/3! -n!) * 0! - 3! when n = 8.

ladokuntlad:
is it
(9!/(3!-n!))*(0!-3!)
or
(9!/(3!-n!))*0!-3!
or
(9!/3!-n!)*(0!-3!)
or ur question as stated?

all4naija:
As stated.

Thank you.
