1. Mathematics - Q&A

KUSH: questions like this should be clearly set because there is a difference between : log 100/2 and (log 100)/2 log 100/2 = log 100 - log 2 = 2 - 0.3010 = 1.699 and log (log 100)/2 = 2/2 = 1

aerorodder1: 8^2=64, (64)^1/3 = 3^64^1=4

aerorodder1: d=rt..solve for r...r=d/t r=rate,d=distance, t=time, 24/t=r t= 45/.60 =(.75) 24/(.75)=32mph

aerorodder1: I'm sorry again I meant [mhos] conductance law!opposite of resistance, ohms law!

aerorodder1: =~22/7 or ~3.14159265359. 22/7-2= 6.28 Radians, or 2, or 360 degrees 3.14159265359-2= 6.28 2+3= ~

aerorodder1: X+Y^2/ X+Y^8 =^2-^8 Or ^-6

aerorodder1: Sohcahtoa...(Soh) (cah) (toa) CosA=adj/hyp, (c=4/5),cah= .8 SinA=opp/hyp, (S=3/5),Soh= .6 TanA=opp/adj, (t=3/4),toa= .75

PART66Online: Hi. Check this good article: mathsisfun.com/least-common-denominat...

riad: YES BUT IT SEEMS AS 1 MULTIPLE BY 1/4

PART66Online: Hey! As I remember this questions was already discussed, please try to look trough Q&A.

andyrhcp104: Thanks Dimky

bharatbc: There are two famous methods for representing degrees and their fractional parts. 1.Decimal degree method e.g 76.45 degrees 2.DMS(degree minute second) method e.g 167 degrees 46 minutes 47 seconds As we know that if the sum of the measures of two angles is equals to 180 degrees, the angles are supplementary. To find the supplement of any angle, subtract the angle from 180 degrees. first write the 180 degrees in the form of degree minute second as required. 180 degrees=179 degrees 59 minutes 60 seconds (borrow 1 degree from 180 degrees. 1 degree = 60 minutes. again borrow 1 minute from 60 minutes.1 minute =60 seconds) now subtract 13 seconds from 60 seconds i.e 60-13=47 seconds , subtract 13 minutes from 59 minutes i.e 59-13=46 minutes and subtract 13 degrees from 179 degrees i.e 179-13=166 degrees therefore answer is 166 degrees 46 minutes 47 seconds To find complement of any angle, replace 180 degrees with 90 degrees and follow same process.

llew89_123: Firstly if you simplify the first part of this (3x^2-6xy). You can do this by finding the common values in both 3x^2 and -6xy. Coincidentally this (x-2y), so this ill now read 3x(x-2y). A good tip is to multiply back out the bracket once you have found this to double check the first park of the answer. Now substitute this back into the original question so it reads 3x(x-2y)/(x-2y). Looking at this you can now cancel out both the (x-2y) on either side to leave you with 3x on its own.

nahansiang: It is same shape and same size. Same shape but different size refers to similar triangle.

Dsutt0n: Hi, The equation for the area of a sphere is - A = 4r^2 So for this equation we have the radius of 2. Therefor 2^2 = 4 x 4 = 16 The is a symbol for pie and does not require you to work it out.

fngosa2014: Thank you all. I have now passed the maths paper.

mfranj1: Thanks!

krishnavikash: its area is calculated by 1/2 * sum of parallel sides * perpendicular distance between them

Sina: (2x)^2 * (z)^2 * (3x - z^2 ) = 4x^2 * z^2 * (3x-z^2) = {(4x^2 * z^2)*(3x) - (4x^2 * z^2)*(-z^2)} = 12x^3 * z^2 - 4x^2 * z4 Thus; (12x^3*z^2 - 4x^2*z4) / 2 ==> 6x^3 * z^2 - 2x^2 * z^4

alland: 0=ut + 1/2at^2 remove t as a common factor which leaves t(u + 1/2at)= 0 equate t=0 and u + 1/2at = 0 1/2at= -u t = -2u/a

PART66Online: Hello. This question was already explained here: part66online.com/index.php?mod=view_q...

JPRASAD2015: (X^(2+3))3= (X^5)3= X^(5*3)= X^15

khaula: If the number start by zero therefor numerators must be less than the denominator.

piesoup: Thank you Dimky!
