Find 5 rational number between 1 and 2 |
|
Answer» 7/6,8/6,9/6,10/6,11/6 Let the two given numbers be a and b respectively a= 1 and b=2We know that the rational number between a and b is given by (a + b)/2So the rational number between 1 and 2 = (1+2)/2 = 3/2Then, Rational number between 1 and 3/2 =[1+(3/2)]/2 = 5/4Then Rational number between 1 and 5/4 =[1+(5/4)]/2 = 9/8Then Rational number between 3/2 and 2 =[(3/2) + 2]/2 = 7/4Then Rational number between 7/4 and 2 =[(7/4) + 2]/2 = 15/8 Hence the five rational numbers between 1 and 2 are 3/2, 5/4, 7/4, 9/8, and 15/8 We can write 1 and 2 as rational numbers with denominator 61=6/6,2=12/6Then 7/6,8/6,9/6,10/6,and11/6are the numbers between 1 and 2.So, five rational numbers are 7/6,4/3,3/2,5/3 and 11/6. |

Show that sum of angles(ABC)of a triangle is 180° |
| Answer» In order to prove that the sum of angles of a triangle is 180, you must know the theorems of angles of a triangle.We know that, alternate interior angles are of equal magnitude.This\'ll help us get the answer. Let us assume a triangle ABC. Now we have to substitute the angles.∠PAB + ∠BAC + ∠CAQ = 180°. where PQ line parallel to side BC touching vertex A.∠PAB = ∠ABC & ∠CAQ = ∠ACB BECAUSE alternate interior angles are congruent..Hence we get, ∠ABC + ∠BAC + ∠ACB = 180° [Proved] | |

Why we did x-1 in ex 4.3 ques 4 |
| Answer» Total distance covered = xTotal fare = yFare for the first kilometer = 8 per kmFare after the first 1km = 5 per kmIf x is the total distance, then the distance after one km = (x-1)kmi.e., Fare after the first km = 5(x-1)According to the question,The total fare = Fare of first km+ fare after the first kmy = 8+5(x-1)y = 8+5(x-1)y = 8+5x – 5y = 5x+3Solving the equation,When x = 0,y = 5x+3y = 5×0+3y = 3When y = 0,y = 5x+3o = 5x+35x = -3x = -3/5\txy03-3/50\tThe points to be plotted are (0, 3) and (-3/5, 0) | |
