3.

The lcm of two numbers is 14 time their hcf .the sum of limited and hcf is 600.if one number is 280,then find the number

Answer»

Let the HCF be x.
therefore HCF is 14x.
ATQ the SUM of LCM and HCF
=x+14x=600
15x= 600
x= 40
therefore LCM =560
Now let the other number is y and the GIVEN number is 280.
We know that,
PRODUCT of the numbers = LCM ×HCF
y × 280= 560 × 40
y = (560 × 40) ÷ 280
y = 2 × 40
y = 80
so the other number is 80.
HOPE THIS ANSWER HELPS YOU.

Factorise by taking out the common factor : ab(a^2+b^2-c^2)-bc(c^2-a^2-b^2)+ca(a^2+b^2-c^2)

Answer»

AB(a²+b²-c²) -BC(c²-a²-b²) +CA(a²+b²-c²)

ab(a²+b²-c²) +bc(-c²+a²+b²) +ca(a²+b²-c²)

ab(a²+b²-c²) +bc(a²+b²-c²) +ca(a²+b²-c²)

(a²+b²-c²)(ab+bc+ca)

2x-y+3=0, y=2x-3 apon 2

Answer» Hey There !!

Given equation, 2x – y + 3 = 0
and y = ( 2x – 3 ) / 2

Substituting y's value in given equation,
2x – [ ( 2x – 3 ) / 2 ] + 3 = 0
4x – 2x – 3 + 6 = 0
2x + 3 = 0
2x = – 3
x = – 3 / 2

Is 33/375 a terminating decimal

Answer»

Heya

33/375 = 11/125

By actual division we get the ANSWER as 0.088 which is a terminating decimal

Without actual division,

125 can be written as 5³

A rational NUMBER' decimal expansion is terminating, if the denominator will have its prime FACTORS as 2 or 5 or both 2 and 5.

Here the prime factors of 125 is 5.

Hence the decimal expansion will be a terminating one.

Hope it HELPS you! ^_^

Please answer this with brief explanation 2√3- √5 / 2√2 + 3√3

Answer» HI ,

( 2√3 - √5 )/( 3√3 + 2√2 )

RATIONALIZE the DENOMINATOR ,

= [(2√3-√5)(3√3-2√2)]/[(3√3+2√2)(3√3-2√2)]

= [2√3(3√3-2√2)-√5(3√3-2√2)]/[(3√3)²-(2√2)²]

= ( 18-4√6-3√15+2√10 )/( 27 - 8 )

= ( 18 -4√6 + 2√10 - 3√15 )/19

when the side of a square increased by 5cm, the area of the square increased by 135(cm)square. find the length of the side of the square

Answer»

Let SIDE of SQUARE is X cm
Now area of Square is X^2-------(1)

If side is increased by 5CM then new area is 135 cm^2 more than old area.From here we get that,

(X+5)^2=X^2+135

X^2+25+10X=X^2+135

10X=110

So X=11cm

Find 6 rational numbers between 1/2 and 3/7

Answer» IM GIVING you some steps
If m and n be two rational numbers such that m < n then 1/2 (m + n) is a rational number between m and n.


1. Find out a rational number lying HALFWAY between 2/7 and 3/4.

No it is not a TERMINATING DECIMAL

41.

Is 12/35 a terminating decimal

Answer»

No, 12/35 has not TERMINATING decimal EXPANSION because you can find EASILY the number is in p/q form i.e. rational number is terminating or not by using prime FACTORIZATION on denominator(check the p/q number is in always lowest form).If the denominator have only prime factors 2 or 5 then the p/q is a terminating decimal expansion.

42.

Afzal purchased an old motorbike for rupees 16000. If the value of the motorbike after 2 years is rupees14440 find the rate of depriciation

Answer»

If you WANT statements then you can WRITE like this-                             
cost of the motorbike purchased by afzal before 2 years = rs 16000    
cost of the same motorbike after 2 years = rs 14440
rate of despriciation = rs 16000-rs14440
                                =rs 1560
therefore the rate of despriciation is rs 1560

the length of a rectangle exceeds its breadth by 5cm. if the length and breadth are increased by 1cm,the area increase by 34(cm)square. find the length and breadth of the rectangle

Answer»

Solution:

LET length be xcm and BREATH be y cm.

ATQ,=> X+5= y.... (1)

=> AREA of rectangle= (x+5).y

=> (x+5) (x+5) using 1.

= x^2+25+10x

now,
according to SECOND condition.

=> (x+1)(y+1)=x^2+ 10x+25+34

=> (x+1) (x+5+1)=x^2+10x+59 (using 1)

=> (x+1) (x+6)= x^2+10x+59

=> x^2+6x+x+6= x^2+10x+59

=> x^2+7x+6= x^2+10x+59

=> -3x= 53

=> x=53/3 (length can't be negative)

How to learn all trigonometric formula in class 11

Answer»

Hello frnd here's the answer to the given question

Maths is an logical, reasoning and applicable subject. It is used in our daily lives too..

TRIGONOMETRY is a huge part of it . It's an easy and interesting chapter . To learn TRIGONOMETRY first we should have an idea about a RIGHT angle triangle and its SIDES so when u know a right angle triangle u can make easily three main formluea of TRIGONOMETRY ie ( sin THETA , COS theta, ) third one is tan theta this is sin / cos
➡ Next after getting this u should learn 3 identities .
➡ U should know what is ALL SILVER TEA CUPS that is nothing but angles which are +ve and wich are -ve at which .
THESE ARE BASICS OF TRIGONOMETRY.NOW ACTUAL PART COMES THOSE ARE

1) Compound angles
2) multiples and submultiples
3) Transformations ( very very imp )
4) periodic functions and types of variation of periodic functions
5) maximum and minimum values
6) trigonometric equations
7) inverse trigonometric functions
8) hyperbolic functions
9) properties of triangles

like this if we see there are many and many these not only helpful here but helps in differentiation, integration etc etc

for all getting these topics we should know the basics of we are perfect than we can play with trigonometry

here as I've not have to keep pics I'll keep basics for u my frnd

hope ull understand this easiest chapter and play with it in whatever exams u write ...
ALL THE BEST FRIEND........
