Ifyx: 08093459095,eagerly anticipating o

*whispers to his ears..* hope say d dude go fit send airtime to our numbers sha...

The sides of a regular polygon are produced so that evry pair of exterior angle and interior angle is ratio 1:4. Calculate
a.the size of an exterior angle
b.number of sides of d polygon

esharp: drop d bomb i knw say omodave neva hear ds!!!! no whyning plssssssssssss

bomb ke!...abeg o,no b bomb we nid na d gudnews oo!

Ifyx: tot u were a 1st choice aspirant

yes I am,buh stil waitin 4 d 2nd list cos I did COC

Arlex: abi o...but what if de extend the deadline?...all i know sha b4 february de will hav release d 2nd list.

b4 february gini!!!...abeg no think go dah syd jare!...by God's grace it will be out b4 january or on jan

Ifyx: wetin?

d waiting is tiresome,I fink d guy is just fed up,...God will help us all

Ifyx: Ehn!dapada!

hmn!

Babaty87: Question 3:simplify (root 2+1)^3+(root 2–1)^3Thanks in advance. Please show your workings.

if u av d idea of binomial expansion use it sir,.and if u dnt u can simply do daht by pickin each of d terms and expand
dat is,(root2+1)^2(root2+1)+(root2-1)^2(root2-1)
try and expand each separately,u wil arrive at an expression,(5root2+7) +(5root2-7)
5root2+5root2+7-7
so d ans is 10root2
op d explanationz helpz,..sorry 4 d dlay,netwrk is poor here

Babaty87: Question 1: An hemispherical tank of diameter 10m is filled by water issuing from a pipe of radius 20cm at 2m per second, Calculate correct to 3 s.f. The time taken in minute to fill the tank?
Question 2: If 8^x/2=2^3/8*4^3. Find x?
Question 3:simplify (root 2+1)^3+(root 2–1)^3
Thanks in advance. Please show your workings.

d=10m r=5m
rate of delivery per sec =2ms-1
radius of pipe=20cm=20/100=0.2m
vol. Of hemisphere=2/3TTr^3
2/3*22/7*5^3
261.905cm3
note: since d rate of discharge by d pipe per second is 2, den height of d pipe =2m
vol. Of pipe used in dischargin water per sec=TTr2h=22/7*0.2^2*2
v=0.251m^3/s
Time to fill the tank in min =vol. Of pipe per sec * T =vol. Of hemisphere
wher T is d Time
0.251*T=261.905
T=261.905/0.251
T=1043.445/60=17.39
17.4 to 3s.f
2. 8^x/2=2^3/8*4^3/4
note,dat u av to find d index and power of each term of d terms if possible
so doing,we av 2^3(x/2)=2^3/8*2^2(3/4)
2^3x/2=2^3/8*2^3/2
accordin 2 d law of indices,x^y*x^z=x^y+z
so derefor,2^3x/2=2^(3/8+3/2)
lets find d Lcm of d exponents @ d right hand side
2^3x/2=2^(3+12)/8
2^3x/2=2^15/8
2 eliminates each oda since dey are dsame
and d eq bcomz 3x/2=15/8
cross multiply
x wil giv us 5/4
no 3,..wil take much of my tym bro,i gat to stop here!

Babaty87: Please help our on this mathematics questions. Please show your workings. Thanks

sir! D smfn is blurred,it cant b viewd properly

Babaty87: Please help our on this mathematics questions. Please show your workings. Thanks

bros,.plz re ryt d smfn,..it cant b viewd properly

Urom Ota: can u pls paste d questn again. Tnx

dnt worry man,..lets anticip8 4 anoda den!,...dou u can stl get it from page 28

Urom Ota: wot questn r we talkn abt pls nd wot could b d answer. Tnx in advance.

d mathematics' sir. And d ans is 8

Kendzyma: 9.5

plz show ur workinz xo dat I can possibly point out ur mistake sire coz dats not d ans,...d ans is a whole no nt decimal no!

We thank God all has cum bak 2 normal!......#United we wil 4eva be!

Bethilicious: Gosh! Did I just get insulted by an anonymous!?

Tommybob, truth is, I hardly ever post stuff here cos of people like you and why do I get so unfortunate that when it presses me to post, I am confronted by your kinda person?..... Look, I don't know you but I respect myself a lot and expect pple shud do same... afta posting dat hell of an insult, u go around seekin sympathy n writing sorry speeches!? Just know dat all u sent as insults are yours...evry word of it. And kip ur apology to urself.... I hate it as much as I detest that spirit in you!

gurl,u'v taken dis too far,....I avnt @anytym thought u would bring dis up to dis level,.buh Y av u intend casting rage on d guy,all bcoz he was jokin wid u
besides d fact dat he was only jokin,he has aswell apologised for almost 4tyms or so,plz I am pleadin,get dis cantankerous act outta ur self and stand 2 b a calm gurl#I MEANT NO OFFENCE

EMMYCOOL4: EMMYCOOL4]guy hlp me solve these questions nd show workings.
1)what effort will a machine of efficiency 90% apply to lift a load of 180N if its efforts arm is twice as long as its load arm?
2)calculate d workdone when a force of 20N streches a spring by 50mm.
3)a gas at a pressure of 10^5Nm^-2 expands frm 0.6m^3 to 1.2m^3 at constant temp,the workdone is?

£=90% L=180N R=2r whr R and r are d effort and load arm respectively
since velocity ratio =effort(R) distance/load dstance(r)
M.A=L/E
then £=M.A/V.R*100%
£=L/E*r/R*100%
rem,R=2r and r=r
90=180/E*r/2r*100
90*2*E=180*100
180E=18000
:.Effort=100N

2. Force=20N extension=50mm=50/1000=0.05m
workdone=?
Rem W=1/2ke^2
also W=1/2fe
W=(1/2)20*0.05
W=0.5J
