Seamione: Well, didn't know that. All i saw were several attempts to solve the problem with combination. |
Re: Nairaland Mathematics Clinic by Antoinne: 8:59am On Sep 02, 2015 |
Guys, I've been a bit busy out of here. Hence my frequent absence. However i have an idea i think we should all talk about. With this combined knowledge and effort at helping people solve problems, creating maths problems, and encouraging discourse, wouldn't it be nice to take this to a completely different platform and create some kind of "online business" out of it? Just wondering... agentofchange1, Seamione, dejt4u, Karmanaut, jackpot, and others I've failed to mention. |

[quote author=Mayour11 post=37568523]Help me check this out 1) A uniform half-meter bar AB is balanced horizontally across a knife-edge placed 15cm from point A. A mass of 30kg is hang at the end of A. What is the weight of the bar? I got 450N, pls help me verify it. ans= 75kg or 750N. 1 Like |

Mayour11: I got 450N too. |

chezholy: How did you arrive at this answer Sir.? |
Re: Nairaland Mathematics Clinic by agentofchange1(m): 11:17am On Sep 02, 2015 |
Antoinne: yea sure it will, av also gave it a thought some times back , maybe the Mods, super mods n Oga seun need to be informed , then we hear their response on d matter . what thinketh thou? sir RICHIEZ. wer art thou ? |

Please, Richiez, Agentofchange1 Benbuks Bolkay... And other Mathematics generalismo. Please help a brother out:
Pls, I still have few left. Please, help me please I beg you. |
Re: Nairaland Mathematics Clinic by Nobody: 9:20pm On Sep 02, 2015 |
@Umartins1. Solution to some attached. If you do not understand questions 1 and 2 there's an example here
|
Re: Nairaland Mathematics Clinic by Nobody: 9:37pm On Sep 02, 2015 |
For question 6: The angle between two lines given their gradients as m1 and m2 respectively is given as: θ = tan-1 |{m 1 - m 2 } / (1 + m 1 × m 2 )| There is another formula which involves finding vectors on the lines and using their dot products but it isn't required here since we're using their gradients. |
Re: Nairaland Mathematics Clinic by Nobody: 9:54pm On Sep 02, 2015 |
@Umartins1 Number 4: The [y -intercept] is the point where the line crosses the y-axis. To find the y-intercept, we substitute 0 for x in the equation, because we know that every point on the y -axis has an x -coordinate of 0. Once we do that, we can solve to find the value of y . When we make x = 0, the equation becomes y=-1 Therefore the co-ordinates of B = (0, -1) 7) I got 2. By directly substituting the percentages for the respective variables. Don't know if it's correct-- or even legal. |
Re: Nairaland Mathematics Clinic by Mayour11(m): 10:06pm On Sep 02, 2015 |
Mayour11: Pls, this has not been attended to yet Karmanaut, agentofchange1, jackpot, dejt4u, seamione, Richiez, et al. |
Re: Nairaland Mathematics Clinic by Nobody: 10:22pm On Sep 02, 2015 |
@Umartins1 Solution to question 10 attached. It's left for you to write the answer in linear form if you so wish. Cheers.
|
Re: Nairaland Mathematics Clinic by echibuzor: 4:43pm On Sep 03, 2015 |
Umartins1: 4. Coordinate of B is (0, -1) You said it strikes y-axis at B, well the whole of y-axis is at x=0, so just put zero in your equation and voila! |
Re: Nairaland Mathematics Clinic by jackpot(f): 11:46am On Sep 05, 2015 |
Antoinne:like solving people's assignments for a fee? |
Re: Nairaland Mathematics Clinic by Seamione(m): 11:57am On Sep 05, 2015 |
jackpot:might not necessarily be assignments |
Re: Nairaland Mathematics Clinic by Antoinne: 1:14pm On Sep 05, 2015 |
jackpot: agentofchange1:Not exactly. Creating some kind of tutoring website where content can be delivered for free, and discourse especially encouraged. I'm not business-minded, but I assume there's some way profit can be reined in from this. That can be taken care of by another person who is intelligent enough to see a business side to this. The point is, all the activities happening here for free and which is volunteer-like is a good one, but could probably be done more positively towards an even greater benefit. Agentofchange1, I'd suppose that should probably be done outside of Nairaland. I'd suppose... Trust me, there's a lot of impact to be made here, especially as Education is one big challenge in Africa. https://www.khanacademy.org/, http://universityofreddit.com/, http://videolectures.net/ |
Re: Nairaland Mathematics Clinic by Antoinne: 1:16pm On Sep 05, 2015 |
Organising what we have already on this page into some deliverables could in fact already help a lot of students. |
Re: Nairaland Mathematics Clinic by Umartins1(m): 3:01pm On Sep 05, 2015 |
Wow, boss Karmanaut, I'm more than grateful. I hope you will help me with the rest. |
Re: Nairaland Mathematics Clinic by Nobody: 10:56pm On Sep 05, 2015 |
I'd suppose that should probably be done outside of Nairaland. I'd suppose...Somewhere with LaTeX support. |

Re: Nairaland Mathematics Clinic by Nobody: 8:59pm On Sep 22, 2015 |
I need help with the following... 1. A chemist has a 20% and 40% acid solutions. What amount of each solution should be used in order to make 300ml of a 28% acid solution. [I got 180ml and 120ml. Am I correct?] 2. The proportion of milk and water in 3 samples is 2:1, 3:2 and 5:3. A mixture comprising equal quantities of all 3 samples is made. What is the proportion of milk and water in the mixture? Help! @Richiez, Agentofchange1 Benbuks Bolkay |
