Here 72x-71x= 52-19x= 33thanks

what do you mean by surveying

(b) is a correct answer

tan(x-y) = sin(x-y)/cos(x-y)

= (sin x.cos y - cos x.sin y)/(cos x.cosy + sin x.sin y)

Divide the numerator and the denominator by cos x.cos y

tan(x-y) = (sin x/cosx- sin y/cos y) / (1 + sin x.sin y/cos x.cos y)

= (tanx- tan y)/(1+ tan x.tan y)

Why are u posting formulas what is ur question, are u asking for the proof of the formula

13x + 10 = -3x + 4213x + 3x = 42 - 10 16x = 32 x = 2

12x10=120मी2. 10x8=80सेमि120मी=12000सेमि120×100×100= 1200000÷80=15000B) 15000

12×10 =120 10×8=80 120=12000120×100×100=1200000÷80=15000 =15000 is answer

the answer is 15000rectangular tiles

AREA =12*10=120m square=1200cm squarenow n* are an*80=1200n=1200/80=15 tiles

क्षेत्र = 12 * 10 = 120 मीटर वर्ग = 1200 सेमी वर्गअभी वn * a हैंn * 80 = 1200n = 1200/80 = 15 टाइलें

3600 = 2^4*3^2*5^23240 = 2^2*3^4*5H.C.F = 36 = 2^2 *3^2Since H.C.F is the product of the lowest power of common Factor, so the third Number must have (2^2 *3^2) as its factor.Since L.C.M is the Product of Highest power of Common Prime Factor, So the Third number must have 3^5 and 7^2 as its factor.Therefore, the third number = 2^2*3^5*7^2

answer

Total fabric left = 6.75 - 3.45

= 3.30 metres

length of the fabric =45 1/4length of fabric she took tomake 12 curtains. = 38 1/3length of fabric used to make 4 cushions =45 1/4 - 38 1/3so, convert it into improper fractions = 181/4 - 114/3now find the LCM of the denominator of the fractions which is 12 now bring 12 as the denominator by multiply it by a number gives 12 and with the same number multiply the numerator alsolike this,=181×3/4×3 - 114×4/3×4= 543/12 - 456/12now both are like fractions so subtract it= 543-456/12=87/12so, 87/12 metre fabric is used to make 4 cushion,but the question also says that you have to find length of fabric used to make 1 cushion so we have to divide 87/12 from 4so, 87/12 ÷4 = 87/12÷4/1reciprocal = 87/12 × 1/4 =87/48now convert it into mixed fraction= 1 39/48therefore, 1 39/48 metre fabric was used to make 1 cushion

Let the number of shirt be x and pant be y

=> x + y < 10

now if x = y +2

then y+2 +y < 10=> 2y + 2 < 10=> 2y < 8 => y < 4

maximum number of pant can be 3

thank you
