3x-5y-4=0 and 9x= 2y+7 |
| Answer» 3X - 5Y = 4----------(1)9X - 2Y = 7-------------(2)From EQUATION (1) we get,3X - 5Y = 43X = 4+5YX = 4+5Y/3 -------------(3)Putting the value of X in equation (2)9X - 2Y = 79 × (4+5Y/3) - 2Y = 73(4+5Y) - 2Y = 712 + 15Y - 2Y = 713Y = 7 -1213Y = -5Y = -5/13Putting the value of X in equation (3)X = 4+5Y/3 => 3 + 5 × -5/13 = 3 - 25/13 /3X = 39 - 25/13/3 = 14/13/3 => 14/13 × 1/3 => 14/9 | |

Find the coordinates of the points of trisection of the line sement joining (4,-1) and (-2,-3) |
| Answer» Let A(4,-1) and B(-2,-3) be the given points.Let P(x,y) and Q(a,b) be the points of\xa0trisection of AB so that AP = PQ = QBHence P divides AB internally in the\xa0ratio 1 : 2 and Q divides AB internally\xa0in the ratio 2 : 1By the section formula, the required points areAP = 1PQ = 1QB = 1Section formula internally = (lx₂ + mx₁)/(l + m) , (ly₂ + my₁)/(l + m)P divides the line segment in the ratio 1:2l = 1 m = 2 A(4,-1) and B(-2,-3) = [(1(-2) + 2(4)]/(1+2) , [(1(-3) + 2(-1)]/(1+2) = (-2+8)/3 , (-3-2)/3 = 6/3 , -5/3 = P (2 , -5/3)Q divides the line segment in the ratio 2:1l = 2 m = 1 = [(2(-2) + 1(4)]/(2+1) , [(2(-3) + 1(-1)]/(2+1) = (-4+4)/3 , (-6-1)/3 = 0/3 , -7/3 = Q (0 , -7/3)\xa0 | |

How to study for standard maths |
|
Answer» Please like if you like this It\'s really simple to study for standard.I have also choosen standard coz i love maths. U only have to firstly understand that what\'s in this chapter then study each chapter carefully and solve all the questions of your ncert and also solved examples of ncert then if u feel that you have completed your full ncert solved and unsolved so then u can also solve Rs book questions, it\'s not necessary to solve all. Then u can solve the previous years paper and sample paper in the last two months before exam and this is enough and I\'m 100% sure if u followed this u will get full marks in math.I always get full marks in math. And I got 97%in 8th and in 9th I scored 96.67%in half yearly Its simple no need to have any tension regarding standard for maths , its just depend on u , how you r going each subject wise topic carefully... |

Use Euclid division algorithm to find HCF of 867 and 255 |
|
Answer» The HCF is 51 By using Euclid division algorithma = bq + rwhere a is > bso a = 867 and b = 255867 = 255 × 3 + 102here r ≠ 0 so a = 255 and b = 102255 =102 × 2 + 51here r≠0 so a = 102 and b = 51102 = 51 × 2 + 0here r = 0so, Hcf of (867,255) is = 51 |

What is irrational number |
|
Answer» A no. is known as rational if it is not in the form of p/q and p and q are not integers . So we can say that the number is irrational.FOR EXAMPLE: 1.101001000100001......or in the form of pye or root 2, 3, 5, 7.......... A number ‘s’ is called irrational if it cannot be written in the form p/q, where p and q are integers and q ≠ 0. E.g.: E.g.: 1.234674322345634232789064590812343…… or ∏, √2 etc, |

Why all circles are similar |
| Answer» Similarity is a quality of scaling: two shapes are similar if you can scale one to be like the other, like these triangles ABC and DEF. Since all circles are of the same shape (they only vary by size), any circle can be scaled to form any other circle. Thus, all circles are similar! | |
