on RATIONALISING the denominator

(1/4+√2 ) × ( 4-√2 / 4-√2)

= 4-√2/ 4² - (√2)²

= 4-√2 / 16 - 2

= 4-√2/14

1/x = (4-√2)/14

Find five rational numbers between 4/5 and 5/6.​

Answer»

Step-by-step EXPLANATION:

first, we CHANGE these into numbers with same DENOMINATOR .

4/5=24/30

and now ,

5/6=25/30

Now ,let no. of rational numbers to be find be n.

then we will find value if n+1

Here , n is 5

then n+1=6

We will multiple both the numbers by (n+1)/(n+1)

i.e. 6/6

FIRST NUMBER

(24/30)*(6/6)

=144/180

SECOND NUMBER

(25/30)*(6/6)

=150/180

Here we find 5 rational no. between 144/180 & 150/180

that are

145/180 , 146/180 , 147/180 , 148/180 , 149/180

These are the numbers between 4/5 and 5/6

You can write in simplest FORM too

Class - 9

Chapter -  Areas of Parallelograms and Triangles. ##9

Page ## - 159

Exercise -  9.2 Q ## 5

Answer:

(i)PROVED!

(ii)PROVED!

Explanation:

Given Problem:

In fig. 9.17  PQRS and ABRS are parallelogram PQRS  is a parallelogram and X is any point on side BR.

Show that:

(i) ar (PQRS) = ar (ABRS)

(ii) ar (AXS) =\frac{1}{2}  ar (PQRS)

Solution:

First of all we have show:

(i) ar (PQRS) = ar (ABRS)

--------------

Method:

Since PQRS is parallelogram

PQ || RS                             (Opposite sides of parallelogram are parallel)

&ABRS is also a parallelogram

So,

AB || RS                       (Opposite sides of parallelogram are parallel)

Since,

PQ || RS & AB || RS

We can say that,

PB || RS

Now,

PQRS & ABRS are two parallelograms with same base RS and between the same parallels  PB & RS

∴ ar (PQRS) = ar (ABRS)

--------------------

★★Parallelograms with the same base and between the same parallels are equal in area.★★

-------------------------------------------------

Now to show:

ar (AXS) =\frac{1}{2}  ar (PQRS)

------------------

Method:

Since ABRS is a parallelogram,

AS || BR                      (Opposite sides of the parallelogram are parallel)

Δ AXS and parallelogram ABRS lie on the same base and are between the same parallel lines AS and BR,

∴Area (ΔAXS) = \frac{1}{2} Area (ABRS)

★We have proved in part (i) that,

Area (PQRS) = Area (ABRS)★

⇒Area (ΔAXS) =  \frac{1}{2} Area (ABRS)

★The area of the triangle is half of the parallelogram if they have the same base and parallels.★

★Hence,

PROVED!!★

Given : Polynomial 2x^9 + 7x^3 + 191.

To find : What is the degree of the polynomial ?

Solution :

Degree is defined as the highest power of a TERM in a polynomial.

The degree of a polynomial is the same as the degree of the term with the highest DEGREES.

Polynomial 2x^9 + 7x^3 + 191.

Here the leading term is 2x^9.

THEREFORE, the polynomial is of the 9th degree.

the density of a piece of clay is 1.8 in cgs system of unit. The corresponding value in S.I. unit system is what ??​

Answer»

Answer:

The DENSITY of the clay in the SI UNIT system is 1800 kg/m^3.

Step-by-step explanation:

The unit of density in CGS system is g/cm^3

Also, the unit of density in the SI system is kg/m^3

THEREFORE, g/cm^3 when changed to kg/m^3,

We get the relation as:

1 g/cm^3 = 1000kg/m^3

So, the given density is 1.8 g/cm^3

HENCE, the density in the SI unit is 1800 kg/m^3.

Challenge1 Tyron played 112 games of Chess this year. He won 24 more games than thenumber of games he lost. How many games did he win?​

Answer»

Step-by-step explanation:

LET the no. of GAMES he LOST be X

then the no. of games he won = x+24

A.T.Q.

total matches =112

We know total match = win + lose

x +(x+24)=112

x+x+24=112

2x+24 = 112

2x=112-24

2x=88

x=44

Now , x is the no. of matches he lose

lose +24=win

44+24=no. if win

therefore , total no. of won matches is 68 .
