the present age of Mr Sen And his son are in ratio 17:9 if the ratio of their ages 9 years ago was 7: 3 then find their present age .

Answer»

Let 17x and 9X be their present ages.


Given that their age 9 years AGO is in the RATION of 7:3.


(17x-9):(9x-9) = 7 : 3


3(17x-9) = 7(9x-9)


51x - 27 = 63x - 63


12x = 36


x = 3.


Present age of sen = 17 * 3 = 51.

Describe axiom and postulates

Answer»

In Geometry, "Axiom" and "Postulate" are essentially interchangeable. In antiquity, they referred to propositions that were "obviously true" and only had to be STATED, and not proven. In modern mathematics there is no longer an assumption that axioms are "obviously true". Axioms are merely 'background' assumptions we make. The best analogy I know is that axioms are the "rules of the game". In Euclid's Geometry, the main axioms/postulates are:


Given any TWO distinct points, there is a line that contains them.

Any line segment can be extended to an infinite line.

Given a POINT and a radius, there is a circle with center in that point and that radius.

All right angles are equal to one another.

If a straight line falling on two straight lines makes the interior angles on the same side less than two right angles, the two straight lines, if produced indefinitely, meet on that side on which are the angles less than the two right angles. (The parallel postulate).

A theorem is a logical consequence of the axioms. In Geometry, the "propositions" are all theorems: they are derived using the axioms and the valid rules. A "Corollary" is a theorem that is usually considered an "easy consequence" of another theorem. What is or is not a corollary is entirely subjective. Sometimes what an author thinks is a 'corollary' is deemed more IMPORTANT than the corresponding theorem. (The same goes for "Lemma"s, which are theorems that are considered auxiliary to PROVING some other, more important in the view of the author, theorem).


A "hypothesis" is an assumption made. For example, "If xx is an even integer, then x2x2 is an even integer" I am not asserting that x2x2 is even or odd; I am asserting that if something happens (namely, if xx happens to be an even integer) then something else will also happen. Here, "xx is an even integer" is the hypothesis being made to prove it.

Add x square y cube + x y squared and 2x y square + xy

Answer»

One common factor.   a x + a y = a (x + y) 

2:    Sevearl grouped common factor.   a x + a y + b x + b y = a(x + y) + b(x + y) = (a + b ) (x + y)

3:    Difference of two SQUARES (1).   x 2 - y 2= (x + y)(x - y) 

4:    Difference of two squares (2).   (x + y) 2- z 2 = (x + y + z)(x + y - z) 

5:    Sum of two cubes.   x 3 + y 3 = (x + y)(x 2- x y + y 2) 

6:    Difference of two cubes.   x 3 - y 3 = (x - y)(x 2 + x y + y 2) 

7:    Difference of FOURTH powers.   x 4 - y 4 = (x 2 - y 2)(x 2 + y 2) = (x + y)(x - y)(x 2 + y 2)

If x+1/x=4find the value of x-1/x

Answer»

X + 1/x = 4

On squaring both SIDES, we get

x^2 + 1/x^2 + 2(x) (1/x) = 16

=> x^2 + 1/x^2 + 2 = 16

=> x^2 + 1/x^2 = 14

On subtracting 2 from both sides, we get

x^2 + 1/x^2 - 2 = 14 - 2

=> x^2 + 1/x^2 - 2(x)(1/x) = 12

=> ( x - 1/x)^2 = 12

=> x - 1/x = 2 ROOT3

Cube root in each of the following using prime factorization 250047

Answer»

Hi friend here is ur answer
Step by step simplification process to get cube roots radical form and derivative:
First we will find all factors under the cube root: 250047 has the cube FACTOR of 3969.
Let's check this width 3969*1=250047. As you can SEE the radicals are not in their simplest form.
Now extract and take out the cube root 3969 * 1. Cube of 3969=63 which results into 631All radicals are now simplified.
The radicand no LONGER has any cube factors.

A bill amount Rs 15000.Find the difference in rupees between single discount of 50% and the successive discount of 30 % and 20 % on same bill

Answer»

15000 * 50/100 =7500
Means 15000-7500=7500

15000*30/100=4500
Means 15000-4500=10500
10500*20/100=2100
Means 10500-2100=8400

So DIFFERENCE between them =8400-7500=900 ANS

If x-3=1/x find the value of x*x +1/x*x

Answer» X - 3 = 1/x

=> x - 1/x = 3

On squaring both sides, we get

( x - 1/x)^2 = ( 3)^2

=> x^2 + 1/x^2 - 2(x)(1/x) = 9

=> x^2 + 1/x^2 - 2 = 9

=> x^2 + 1/x^2 = 11
