Whao i love maths...

A group of engineers has got to build a building..In order to make the buliding a standard and a strong one the ratio of water,cement,soft sand and granite must be in the ratio 1:3:4:2 by mass..If the mass of granite on ground is 40kg and in a mixture of correct proportion with sand and cement..calculate the volume of water needed to mixed up with the resulting mixture if the density of water is 1000kg/m^3 <m^3 means raise to the power of 3>.......,{the question is taken from me off-hand and anyone who is sure can stand up to d challenge and if u get it i promise u a special thing}

^^^ that one is not brain food, it is a weekend ASSIGNMENT, lol!!!!

ok here are few:

A) 10 thieves were caught red handed and arrested. they were placed in front of a firing squad, and shot at point blank range, yet no single men was killed. how is this possible?!

B) NNPC just took the light. you have a CANDLE, a KEROSENE LAMP, a GAS LAMP and a CIGARETTE....... but ONE match only, which one should you light first?

Apparently you light the match first, then the candle and you can use either of both to light the kerosene lamp, gas lamp and cigarette!

But, NNPC don't take light sha. . .

the firing squad fired blanks!

^^^no no they were shooting real bullets.

Opps

weekend assignment,NO

You have got to fuel your generator because you have to watch an important match..But u notice that the petrol you will use contain water and kerosene ..how can you seperate this mixture in other to get your petrol from the resulting mixture.

pls control engineers in the house.i have a very urgent assignment to submit on wednesday 25-04-012.pls,kindly assist on the topic 'mention a real life system that can assume to be a linear system and describe how you will experimentally determine its transfer function in particular clearly state how measurement would be carried out' thanks as you help me out.

^^^ bro, if tomorrow i have the need to employ a control engineer, i hope that this person got their diploma due to merit and nothing else.
what you want people to do is criminal and wrong..... if you have a problem with your school work then talk to your teachers, but asking someone to do it for you is just as wrong as CHEATING.

how can you bring your school assignment here and expect us to do it for you?!

@MR BROWN JAY;what is wrong asking help from an experienced colleague?what u mean by cheating is still not clear to me!so what do u expect me to do if i should see anyone who is ready to be of help,at least to enlighten me on the topic.hope u're not one of those who ahbors laziness

pls help with this trig problem,its urgent......using the trig identity cos3theta=4cos^3theta-3costheta,express costheta as a function of cos3theta i.e costheta=f(cos3theta) explicitly

EVERYTHING is wrong. this is a thread for people to share some brain food and teaser, not to do someone's school assignment.
bro, its so wrong on so many levels!!!

A man was fetching some firewood in a tick forest.The man sighted a lion,silmutaneously and unfortunately the hungry lion also saw the man at a fair distance apart.This was how the hot chase started.The man has the power to cast a disappearing spell that will land him in his home hundreds of kilometre away which can be cast when not in motion and the spell will last for two minutes before it works...If he stays and cast it the lion will catch up with him in a minute and have him as its lunch ..If there is no place to hide on ground in the forest and there is no one to rescue him,but the man live to tell the story ..Suggest how he escaped.

^^^ stand still, cast the spell..........then run like hell!!!!!

in a topic lyk logarithm hw do they place d decimal point after solving 4 d antilogarithm pls i nid answer.pls help me solve dis 4562 divided by 98.76 pls dis question is under logarithm

Joshua15: in a topic lyk logarithm hw do they place d decimal point after solving 4 d antilogarithm pls i nid answer.pls help me solve dis 4562 divided by 98.76 pls dis question is under logarithm

you place the decimal point using the value to the left of the decimal. So, if you have say

1.4564

after you obtain the antilog using 0.4564. You get 2.86. Then you place the decimal using 1 (to the left of the decimal).
so you decimal in 2.86 moves to the right only once. In the end you have 28.6.
You know, this is so that 28.6 can be 2.86 x 10^1

4562/98.6 =
Log(4562/98.6) = Log(4562) - Log(98.6)
= Log(4.562 x 10^3) - Log(9.86 x 10^1).
= 3 + 0.6589648 - 1 - 0.9943172
= 1.6646476

Antilog will give you 46.2.

okay, now, I hope that's not your homework!

The sweetest thing. About math is that you can solve a question in numerous ways as long as you understand it unlike other subjects.....
