Answer» Hey FRIEND!! Let the tens and unit DIGIT of number are x,y First condition : ⇒10x+y=3+4(x+y) ⇒6x−3y=3 ⇒2x−y=1 Second condition : ⇒10x+y+18=10y+x ⇒x−y=−2 Subtract resultant equations ; ⇒x=3 ⇒y=5 ∴two digit number =35 This is a similar question...I HOPE it helps..pls MARK as brainliest!

3.

a 2-digit number is 3 more than 4 times the sum of its digits.if 8 is added to the number ,the digits are reversed.find the number

Answer»

Hey FRIEND!!

Let the tens and unit DIGIT of number are x,y

First condition :

⇒10x+y=3+4(x+y)

⇒6x−3y=3

⇒2x−y=1

Second condition :

⇒10x+y+18=10y+x

⇒x−y=−2

Subtract resultant equations ;

⇒x=3

⇒y=5

∴two digit number =35

This is a similar question...I HOPE it helps..pls MARK as brainliest!

11.	Jf x+1/X =17/4 THEN FIND THE VALUE OF X
Answer» Answer: 4 or 1 / 4 Step-by-step EXPLANATION: ⇒ x + 1 / x = 17 / 4 ⇒ ( x^2 + 1 ) / x = 17 / 4 ⇒ 4( x^2 + 1 ) = 17x ⇒ 4X^2 + 4 = 17x ⇒ 4x^2 - 17x + 4 = 0 ⇒ 4x^2 - ( 16 + 1 )x + 4 = 0 ⇒ 4x^2 -16X - x + 4 = 0 ⇒ 4x( x - 4 ) - ( x - 4 ) = 0 ⇒ ( x - 4 )( 4x - 1 ) = 0 ⇒ x - 4 = 0 or 4x - 1 = 0 ⇒ x = 4 or x = 1 / 4

11.

Jf x+1/X =17/4 THEN FIND THE VALUE OF X

Answer»

Answer:

4 or 1 / 4

Step-by-step EXPLANATION:

⇒ x + 1 / x = 17 / 4

⇒ ( x^2 + 1 ) / x = 17 / 4

⇒ 4( x^2 + 1 ) = 17x

⇒ 4X^2 + 4 = 17x

⇒ 4x^2 - 17x + 4 = 0

⇒ 4x^2 - ( 16 + 1 )x + 4 = 0

⇒ 4x^2 -16X - x + 4 = 0

⇒ 4x( x - 4 ) - ( x - 4 ) = 0

⇒ ( x - 4 )( 4x - 1 ) = 0

⇒ x - 4 = 0 or 4x - 1 = 0

⇒ x = 4 or x = 1 / 4

The numerator of a fraction is 3 less than its denominator. If 2 is added to both theand the denominator, then the sum of the new fraction and original fraction is 2930. Find theoriginal fraction

Answer»

Solution (Question Error):

$\bf{\red{\underline{\bf{Given\::}}}}$

The numerator of a fraction is 3 less than it's denominator. If 2 is added to both the numerator and denominator, then the sum of the new fraction and original fraction is 29/20.

$\bf{\red{\underline{\bf{To\:find\::}}}}$

The original fraction.

$\bf{\red{\underline{\bf{Explanation\::}}}}$

Let the denominator be R

Let the numerator be (r-3)

So;

$\boxed{\bf{The\:orginal\:fraction=\frac{r-3}{r} }}}}}$

A/q

$\longrightarrow\sf{\dfrac{r-3}{r} +\dfrac{r-3+2}{r+2} =\dfrac{29}{20} }\\\\\\\longrightarrow\sf{\dfrac{r-3}{r} +\dfrac{r-1}{r+2} =\dfrac{29}{20} }\\\\\\\longrightarrow\sf{\dfrac{(r+2)(r-3)+(r)(r-1)}{r(r+2)} =\dfrac{29}{20} }\\\\\\\longrightarrow\sf{\dfrac{r^{2}-3r+2r-6 +r^{2} -r}{r^{2} +2r} =\dfrac{29}{20} }\\\\\\\longrightarrow\sf{\dfrac{2r^{2}-2r-6 }{r^{2}+2r } =\dfrac{29}{20} }\\\\\\\longrightarrow\sf{20(2r^{2} -2r-6)=29(r^{2} +2r)}\\\\\\\longrightarrow\sf{40r^{2}-40r-120=29r^{2}+58}$

$\longrightarrow\sf{40r^{2} -29r^{2} -40r-58r-120=0}\\\\\\\longrightarrow\sf{11r^{2} -98r-120=0}$

$\underline{\underline{\bf{Using\:Quadratic\:formula\::}}}}}$

As the given POLYNOMIAL as compared with ax² + bx + c

a = 11
b = -98
c = -120

Now;

$\boxed{\bf{x=\frac{-b\pm\sqrt{b^{2}-4ac } }{2a}}}}}$

$\longrightarrow\sf{x=\dfrac{-(-98)\pm\sqrt{(-98)^{2} -4\times 11\times (-120)} }{2\times 11}} \\\\\\\longrightarrow\sf{x=\dfrac{98\pm\sqrt{9604-(-5280)} }{22} }\\\\\\\longrightarrow\sf{x=\dfrac{98\pm\sqrt{9604+5280} }{22} }\\\\\\\longrightarrow\sf{x=\dfrac{98\pm\sqrt{14884} }{22} }\\\\\\\longrightarrow\sf{x=\dfrac{98\pm122}{22} }\\\\\\\longrightarrow\sf{x=\dfrac{98+122}{22} \:\:Or\:\:x=\dfrac{98-122}{22} }\\\\\\\longrightarrow\sf{x=\cancel{\dfrac{220}{22}} \:\:\:Or\:\:\:x=\dfrac{-24}{22} }$

$\longrightarrow\sf{\orange{x=10\:\:\:Or\:\:\:x\neq \dfrac{-24}{22} }}$

10years ago a mans age was 6 times the age of his son . 12 years later , the age of his son . 12 years later , age of the son will be 27 years . what is the present age of the father

Answer»

$\huge\mathfrak\red{YOUR ANSWER}$

Hello SHANAYA...

let the CHILD's age be = x

10 years ago man's age was 6 TIMES of son

so 10 years before FATHER's age=6x

now 6(x-10 )

12byears later sons age =27

so x+12=27

equations are

father's current age=6(x-10)

sons age after 12 years x+12=27

x can be

x=27-12

x=15

sons current age=15

father's age =6(x-10)

6 X (15-10)

6 X 5

30

current age of father = 30yrs

percent = 30%

ABCD is a trapezium. Find the size of angle CDA, giving your answer to 1 decimal place

Answer»

Given : ABCD is a trapezium. AD || BC , AD = 23 cm BC = 9

AB = 6.5 Height = 6 cm

To Find : SIZE of ANGLE CDA

Solution:

Height = 6 cm => BM = 6 cm M point on AD

Applying PYTHAGORAS theorem

AM² = AB² - BM²

=> AM² = 6.5²- 6²

=> AM = 2.5

CN ⊥ AD

AD = AM + MN + ND

MN = BC = 9 & CN = BM = 6 ( height)

=> 23 = 2.5 + 9 + ND

=> ND = 11.5

Tan ∠CDN = CN/ND

∠CDN = ∠CDA

=> Tan ∠CDA = 6/11.5

=>∠CDA = 27.55

Step-by-step explanation:

VOLUME of resultant FIGURE =volume of sphere/volume of CYLINDER

so,

volume of resultant figure = 4/3 πr3/πr2h aq

=4πr3/3 π r2h

=4:3

.

total surface AREA = 4πr2/ 2πr+πr2

=2:1

Answer» ANSWER: k= -91 Step-by-step explanation: p(x) = x⁴+10x³+25x²+15x+k g(x)= x+7 Putting the value of g(x)=0 We get , x+7=0 , x= -7 Now, we have to PUT the value of x in p(x) (-7)⁴+10×(-7)³+25×(-7)²+15×(-7)+k = 0 2401+(-3430)+1225+(-105)+k=0 196-105+k=0 91+k=0 k=-91

Find K for which x^4+10x^3+25x^2+15x+K IS EXACTLY DIVISIBLE BY X+7

Answer»

ANSWER:

k= -91

Step-by-step explanation:

p(x) = x⁴+10x³+25x²+15x+k

g(x)= x+7

Putting the value of g(x)=0

We get , x+7=0 , x= -7

Now, we have to PUT the value of x in p(x)

(-7)⁴+10×(-7)³+25×(-7)²+15×(-7)+k = 0

2401+(-3430)+1225+(-105)+k=0

196-105+k=0

91+k=0

k=-91

Prove that 2root5is irrational

Answer»

ANSWER:

Step-by-step explanation:

Suppose, it can be written in firm of p/q,and q is not equal to zero.

When p and q are relative PRIME numbers

√5 = p/q, q is not equal to 0~~eq (1)

Where p and q are relative prime numbers

Taking square

5=p2/q2

5=p2/q.q

Taking ONE q on opposite side

5q=p2/q~~(2)

Since p and q being relative prime No's , q cannot divide p and p2

As l.h.s of eq(2) is an integer i.e; nq

Hence l.h.s of eq(2) is not equal to R.H.s

So our assumption is wrong

So √5 is an irrational number.
