If the numerator of a fraction is multiplied by 2 and the denominator is reduced by 5 the fraction become 6/5 and if the denominator is double and the numerator is increase by 8, the fraction become 2/5. find the fraction​

Answer»

Step-by-step explanation:

LET numerator=x

denominator=y

fraction =x/y

ATQ _1

2x/y-5=6/5

10x=6y-30

5x-3y=-15 -----------(i)

ATQ _2

x+8/2y=2/5

5x+40=4y

5x-4y=-40-----------(II)

subtract (i) and (ii)

5x-3y=-15

5x-4y=-40

- + +

___________

0+y=25

___________

y=25

PUTTING this value in eq (i)

5x-3y=-15

5x-3(25)=-15

5x-75=-15

5x=-15+75

5x=60

x=12

hence,

x=12 y=25

( x+1 / x )^3

=( 2+ √3 )^3 + 1^3  /  ( 2+ √3 )^3

=8+√27 + 1 / 8+ √27

=8+√27 + 1 / 8+ √27 * 8+√27 / 8+ √27

Please simplify 7.222222......

Answer»

Answer:

x = 7.222...= \frac{65}{9}

Step-by-step explanation:

LET x = 7.222....----(1)

multiply EQUATION (1) by 10, we get

10x = 72.222....----(2)

Subtract equation (1) from (2) , we get

=> 9X = 65

\implies x = \frac{65}{9}

/* \frac{p}{q} \: form */

Therefore,

x = 7.222...= \frac{65}{9}

1. Find the quotient and the remainder when each of the followingnumber is divided by 138. 31, 44, 85, 1220.​

Answer»

Find the QUOTIENT and the remainder when each of the following

number is DIVIDED by 13

8. 31, 44, 85, 1220.​

Step-by-step explanation:

8 = 13 × 0 + 8

Quotient = 0

remainder = 8

31 = 13 × 2 + 5

Quotient = 2

remainder = 5

44 = 13 × 3 + 5

Quotient = 3

remainder = 5

85 = 13 × 6 + 7

Quotient = 6

remainder = 7

1220 = 13 × 93 + 11

Quotient = 93

remainder = 11

2011 = 13 × 154 + 9

Quotient = 154

remainder = 9

❤♥️❤ QUESTION⤴️⤴️⤴️PLSS HELP ME!!!! THERE R 2 QUESTIONS!!!⭐⭐NOTE:- ⚪⚫ NO IRRELEVANT/WRONG ANSWERS!!! DON'T ANSWER IF U R NOT SURE!!✌✌PLSSS MAADAT KARDO NA !!!:) :) ♥️​

Answer»

Solution :-

1). If LCM if 12 and 42 is 10m + 4 then find the value of 'm'

By splitting 12 and 42 in its PRIME factors .

12 = 2² × 3

42 = 2 × 3 × 7

So we have the LCM

= 2² × 3 × 7

= 4 × 3 × 7

= 84

So as LCM is of the form

10m + 4

→ 84 = 10m + 4

By subtracting 4 from both the sides

→ 84 - 4 = 10m + 4 - 4

80 = 10m

→m = 80 ÷ 10

→ m = 8

So Value of "m"

\huge{\boxed{\sf{= 8}}}

2. What type of decimal expansion of a number

\dfrac{441}{2^2 \times 5^3 \times 7}

Have ?

LET US reduce it step by step :-

\dfrac{441}{2^2 \times 5^3 \times 7}

=  \dfrac{7^2\times 3^2\times}{2^2 \times 5^3 \times 7}

= \dfrac{ 7 \times 3^2}{10^2 \times 5}

= \dfrac{63}{500}

= 0.126

Hence it will have a

Show that any positive odd integer is of the form 6q + 1 or 6 q + 3or 6q+ 5 where q is some integer?

Answer»

Answer:

LET the POSITIVE integer be a and b=6

According to Euclid's division lemma,

a=bq+r where.. 0

Here, a=6q+r....0

So possible values of b are 0,1...5.

Now,

CASE1:r=0

a=6q+0

a=6q.....................EVEN

CASE2: r=1

a=6q+1................ODD

CASE3: r=2,

a=6q+2.................EVEN

CASE4: r=3................

...................

DO SIMILARLY REST PART...............

......................

...............

Hence,any positive odd integer is of the form 6q+1,6q+3 or 6q+5

Length of a rectangle is 2½ times its breadth. if it's perimeter is 70m, find the length and breadth..??Plez answer ;-;​

Answer»

\mathfrak{\large{\underline{\underline{Answer :-}}}}

The Length is 25 m and Breadth is 10 m

\mathfrak{\large{\underline{\underline{Explanation :-}}}}

Given :

Length of the Rectangle = \tt{2 \dfrac{1}{2}} of It's Breadth

Perimeter of Rectangle = 70 m

To FIND :

The Length and Breadth

Solution :

Consider the Breadth as X

Length will be \tt{2 \dfrac{1}{2}x}

\boxed{\sf{Perimeter=2(Length+Breadth)}}

\sf{\implies} \: 2\left[x  +  2\dfrac{1}{2}x\right]  = 70

\sf{\implies} \: 2\left[x  +  \dfrac{5}{2}x\right]  = 70

\sf{\implies} \: 2x + 5x = 70

\sf{\implies} \:7x = 70

\sf{\implies} \:x =  \dfrac{70}{7}

\sf{\implies} \:x = 10

Breadth = 10 m

\rule{300}{1.5}

VALUE of \tt{2 \dfrac{1}{2}x}

\sf{\implies} \:  \dfrac{5}{\cancel{2}}  \times \cancel{10}

\sf{\implies} \: 25

Length = 25 m

\therefore The Length is 25 m and Breadth is 10 m

\rule{300}{1.5}

\mathfrak{\large{\underline{\underline{Verification :-}}}}

\sf{\implies} \: 2(25 + 10) = 70

\sf{\implies} \: 50 + 20 = 70

\sf{\implies} \: 70 = 70

\therefore The Length is 25 m and Breadth is 10 m

If the third and ninth terms area.P are 4 and -8 then which term of thisa.P is zero

Answer»

Answer:

5th term

Step-by-step explanation:

nth term = a+(n-1)d

3rd term = a+(3-1)d = a+(2)d = 4 ----(1)

9th term = a+(9-1)d = a+(8)d = -8 ----(2)

(1)×4 = 4a+(8)d = 16

(1) - (2) = 3a = 24 =>> a = 8

8+2d = 4 =>> 2d = -4 =>> d = -2

a+(n-1)d = 0

8+(n-1)-2 = 0

(n-1)-2 = -8

(n-1) = 4

n = 4+1 = 5

राम अपनी चीजें श्याम की तुलना में 25% सस्ती बेचता है किंतु वे हरि की तुलना में 25% महंगी होती है। तदनुसार हरि की चीज श्याम की तुलना में कितने प्रतिशत सस्ती है।

Answer»

Answer:

40 %

Step-by-step EXPLANATION:

राम अपनी चीजें श्याम की तुलना में 25% सस्ती बेचता है किंतु वे हरि की तुलना में 25% महंगी होती है। तदनुसार हरि की चीज श्याम की तुलना में कितने प्रतिशत सस्ती है।

श्याम की चीज = X

राम की चीज = x - (25/100)x = 0.75x

हरि की चीज = y

राम की चीज = y + (25/100)y = 1.25y

0.75x = 1.25y

3x = 5y

y = 3x/5

x - y = x -3x/5 = 2x/5

((2x/5) /(x) ) × 100 = 40 %

हरि की चीज श्याम की तुलना में 40 प्रतिशत सस्ती ह
