See your log cancelling....datz mathematically wrong....

Yeah, I have asserted that long ago, the funny thing is the way it seems to work for other similar problems liie the example above.

rapins:
Yes.

Good we are on the same page. Did you try the word problem on page 4 about the age of a woman and her husband? That's a bit trickish though I have solved it, you may want to try it too.

rapins:
Check your answer again. Y is number of women ie 60 not the other way round.

Thanks. I have resolved and I got "0.65054625" as the answer. Does this tally with yours?

jdbrasco:
u r gud bro. Jst use dat expression nd u will get ur radius.

Okay, thanks. n= (44/7)r^2. p=99/100. What does the E stand for? And what will be the value so we can solve for r? Thanks.

A Construction Firm wishes to use a group of fifty professionals to execute a project. These fifty are to be selected from 110 engineers. there are Y number of women in the firm and X number of men. The number of male engineers necessary to complete the project are 10100 to base two. If the firm consists of [(50!/49!)+(5²-√{225!/224!})] women, Calculate the value of... [(X²+Y³)25]/e10]+(65/{5×√4}²).


HINT: I refer to this question as a chain of EVALUATIONS in which only those able to manipulate Complexities are able to solve.
GOOD LUCK!

patwilly:
I just followed you. follow back bro.

Done.

jdbrasco:
bro, y equate prob to total n I.e 99/100=11r^2÷7? I think the expression E=nP comes in frm there; where n=44r^2÷7

You can take it up from there sir.I couldn't think of any other way to get the radius

If you add the age of a man to the age of his wife,
the result is 91. He is now twice as old as she was
when he was as old as she is now.
How old is the man and his wife?

The man is 52 years old and the woman is 39 years old. Find the solution attached below...

bataderemi:
I don't actually. nice try tho

Thanks.

mathefaro:
Yeah, he's very correct bro because if
(a + b) log x = log b, then
log x ^{(a + b)} = log b and
x ^{(a + b)} = b. (log 10 cancels each other)
Having said this, I thin the only logical solution to this is the graphical method. One has to draw a graph of y = 2 ^x and y = 4x on the same axis.

Thanks bro. I observed that the same method works for similar problems that was why I asked him to try it with 3^X = 9X

2sExy1:
Benin. It would have been nice to have you reboot my brain. Loved mathematics like mad before... changes happened to me.

Holla at me whenever you come around then and let's hook up.

bataderemi:
aiit... what are u studying?

Computer science at Msc level ( just got in)

bataderemi:
I think if there are 2 GH in 1 cm^2, then in A cm^2 there shld be 2A not A/2 grasshoppers. like
2=1
x=A
so x(1)=2A

Yeah, that will be 44/7 . Thanks. Let me edit.

bataderemi:
This is one of d ojoros that I mentioned sir, the part where u cancelled out d log, it ought to be 2^(x-2) not 2(x-2) tks.

You may be correct sir. Let me know if you have a better solution.

2sExy1:
You seem to have a flair for mathematics. That's nice. Where are you based?

Lagos. You?

bataderemi:
this is harder than d hardest....lol
the probability of finding at least a grasshopper in a circular field is 0.99, if the expected value of grasshoppers in 2 per cm squared, determine the radius of d field. not sure if d expectation is correct... U can just state how u will do it

This is just a try, you can review the solution and answer while we wait dor maths gurus to come try it too.....

bataderemi:
this question is a dead end, we cld not get it in secondary school unless we did ojoro

You can follow this simple method. Same can be used to solve 3^ X = 9X in which X= 3.

Ishilove:
I very much mind

. You are witty; you can make money from mild humour.

Ishilove:
You wanna teach me basic maths?

....Never too late if you do not mind.

Ishilove:
Stop...you're making me dizzy...

Stop...you're cracking my ribs.

Ishilove:
Lol. It is what I think o. I think the last time I did really well in maths was in primary school. After that, it's been downhill all the way

Happy sunday to you too!!

I get. At least, you managed to scale through it at O levels. We can take it uphill in 2 months for the basics.

XXX5:
The password to my pc consists of '0' & '1' (BINARY). There are 720 different ways of combining these digits in which only one is my pss wrd. The password hint shows
"0⁴, 1²". If my password to base ten is the result obtained when sixty is subtracted from the solution of
[(11!/10!)×200]/[2²× {√16 +1²)]....Can you help me figure out my password?

Your password is 110010 and dejt4u is correct. Find my solution attached below.....

Ishilove:
Hian. So that short question is what filled a whole foolscap sheet?

I HATE maths.


*goes back to reading Cyprian Ekwensi's 'Jagua Nana'*

. You are so funny. It is not what you think, just a couple of procedures. Happy sunday!

BSc. Microbiology FUNAAB..work on Bio ethanol

MSc Food and Industrial microbiology FUNAAB..work on Biodiesel

PhD in view ..Industrial Microbiology...Further work on Biodiesel (or bio detergent... Not decided yet)

When I saw your post, I guessed you would be the one and I wasn't wrong. I was in B206 and u stayed in B204 or something with Samson and co. Welldone!

There is nothing hard about this sir. I have solved it. Find the solution attached below......

naijainstinct:
You sound really daft. Wow, you must be so intelligent to have scored 65.88. Did you miss the part where I mentioned I got 70+ last year? I was admitted but didn't accept the offer. Infact, i had the second highest score last year. So I have the experience and when I say this year's test was cheaper, you should know I have adequate knowledge of what i'm saying. More than four times the number of people who took the test this year did last year, so last year's competition was stiffer. Pls don't let me vent my anger on you ok? Unilag ripped many us of our deserved marks and here u are spilling balderdash. Let's assume I did poorly, what bout braine? this is someone I can attest to his intelligence.

Do people who are not sure of their performances call for their scripts? Maybe they do so in your alma-mata, definitely not mine.

Mind you, similar stuff happened last year when people with lesser aggregates were offered admission while people who scored higher were omitted. Cos of this, a female nairalander who was a victim of this fraud last year refused to put in this year despite my persuasion.

Guy, you are very myopic......obnoxiously myopic! (no offence pls)

Sir, what was your scores? If it is true that those that had lower marks were offered admission, we can easily verify that. All you need do is to check the list that was released, copy the ref no/ application no of each candidate and go check their results, so that we will have an idea of what they scored and compare .

braine:
No news yet. I'm jes tired of the thing.

Okay, let's keep our fingers crossed.

braine:
Congrats...

Sup with your department and status?

Computer science has released the admission list, just 38 names. Thank God I made the list. Oseroke, I can see your name on number 19 . Congrats!

braine:
All join, that one sef dey.

Thank you sir. Have you checked again for a possible update?

tit:
so we should vote him president because he gave you a seat?

Why do you have to break this record? You are the dum.best person I came across this year. Your IQ would be a single digit.

braine:
Thanks bro! One extra bottle of beer for you when we finally resume.

. Extra bottle? That means you had one in stock for me before now and that makes 2. Can I replace the beer with ice cream? You know say me, I be "omo mummy"
