Please what is the formular for calculating percentage error

please I need download link to fifa 2014 english commentary asap please

I tried opening the fifa 2014 from play store. It didnt work o pls what can I do? ..or you fit give me another modes apk link please.. And i tried using freedom to open it sane thing again

Please how do i unlock all fifa 2014 mode

stanliwise: Please i need to know the closing date of yabatech registration. I need a quick reply.
Thanks in advance.

after 2nd of September busted!!!!!

smurfy: The best? I am the least on this thread. Just keep the hard questions coming.

i just used what you taught me now to solve "thousands" of polygon problems thanks man ..more questions to come

smurfy: OK.

Polygon

Polygons are plane shapes bounded by straigjt lines. The simplest polygon is the triangle. Then we have quadrilaterals (4-sided). Then we have pentagons (5-sided) etc.

Regular Polygons

Regular polygons have equal sides and angles. Examples are equilateral triangle, square, regular pentagon, regular hexagon, regular heptagon, regular octagon, regular nonagon, and regular decagon.

Finding Sum of Angles

The formula is...
Sum of angles = (n - 2) * 180, where n is the number of sides or angles. The formula works for all polygons.

If given the exterior angle of a REGULAR polygon, then number of side equals 360/&, where & is the exterior angle.

you are the best

smurfy: Question 1's solution is correct. The base, BC, is 7 cm. The height, AD, is 7 cm. So, area is 24.5 cm^2.

It's possible you got the question wrong.

As for teaching of polygon, I'd advice you get relevant materials online. Textbooks can be of great help too.

i tried online and it was futile..no serious site that explain it more better..and as for textbook.no cash just summarize the formulas more question to come

Thanks man please can you cross check that number one workings very well.. Buh the rest are perfect kudos to you smurfy.. and please i don't know anything about polygons.please can you teach me. Here in one page thanks.. More questions to come..am learning ( i hope we have physics and chemistry clinic)

smurfy: 1. BC = 7 cm and AD (altitude) = 7 cm.
Area = 1/2 * BC * AD
= 1/2 * 7 * 7
= 24.5 cm^2

2. Sum of angles = (n - 2) * 180
160 * n = 180 * n - 360
360n - 160n = 360
20n = 360
n = 18
The polygon has 18 sides

3. Let P = x (principal), A = amount
But A = P + I. eqn (*)
From the question, when will A = 2x
Substituting into eqn (*):
2x = x + I, where I is the interest.

Also, I = PRT/100
Substituting...
x = (x * 8 * T)/100
100x = 8xT
100 = 8T
T = 100/8
T = 12.5
So, it'll take 12 and half years for the money to double.

Please am here again oo

Given a triangle ABC, with BC =7cm . AD=7cm and AD IS the altitude of the triangle. Find the area of triangle ABC with workings please
==> 2
Regular polygon has each of it angles as 160(degree) what I'd the number of sides of the polygon..
== 3
How long will it take a sum of money invested at 8 percent to double the original sum.

I love you guyz.. If am a gay i wish to marry both of you.. Buh the later guy is right. Cos there is no 16 ..,in the option buh there is 34. Buh the rest are perfect.. More questions to come because my exam is next week and i wanna blast them in that post utme

Please help me solve these question with clarity

1. Find the total surface area of a solid hemisphere of diameter 6.6

2. A solid is made up of a cylinder with a hemisphere on top. Calculate its surface area.
3. Find the volume of a given triangular prism with a right-angled triangle 9cm by 12cm by 16cm and length 18cm
4.how many tiles each of side 8cm are needed to tile a floor 22m 40cm long by 12m 80cm wide
5.a rectangular pool 10m by 5m is surrounded by a path 1m wide. What is the area path ... Please show workings in all

Is. It. 45 overall or in post utme only ?

Please i need help on how to root my Droid RAZR Motorola ..ASAP PLEASE.. So as to be able to use wifi tethering.. Jelly bean please

So no one is gonna help me with the registration after all.. ?(post jamb)

Please who can help me through the registration process of Yabatech ..i live at aguda surulere Lagos, please is there anybody living near my area..please asap ..

aweonline: chck am nw..or drop ur reg no mak i chck am for u asap

i didnt score up to fifty percent sad

please top whom it may concern.. the question are not the same o. am very sure of that.. the question is not hard but technical.. the reason why i said it is not hard is that you will recognize the question. but you won't be sure of the answer.. but don't yours eyes wella.. i rest my case ( waiting patiently for my result. so help me good amen)

just finished the exam now.. i can't even predict my score chai. damn scared. maths physics chemistry

thank God landed in futa safely...

the volume of water remain the same cos the ice cube have booked its place already.. #team mechanical engineering 30th of July batch A.... boarding my flight on Tuesday

i rep mechanical engineering batch 1

is it how to root or how to partition your memory card?

please i just rootedy xperia arc s and i must say.. i am enjoying it expecially memory card partition omo e sweet.. buh how do i back up and flash custom rom and Please how do i install kitkat

abeg ah dey come to akure from lagos for post jamb next week and ah no get anybody ( chai where am i gonna stay now )

any mechanical engineering asprint here? am one
