If the number x is 3 less than the number y and the sum of the squares of x and y is 29,find the product of x and y​

Answer»

Answer:

X=y-3

y=x+3............(i)

y²+x²=29

(x+3)²+x²=29

2x²+6x+9=29

x²+3x-10=0

(x+5)(x-2)=0

x= -5. x= 2

y=x+3

Hence,

y= -2. y= 5

x•y=10

Find the cost of paining a rectangular wall with dimensions 4m and 3m at the rate of ₹200 per square metre

Answer»

Step-by-step explanation:

Find the cost of paining a RECTANGULAR wall with DIMENSIONS 4m and 3M at the RATE of ₹200 per square metre

  • We need to find the cost of painting. So we have
  • Area of rectangle will be = length x breadth
  •                                            = 4 m x 3 m
  •                                            = 12 sq m
  • So according to question,
  • One square meter of rectangular wall will cost Rs 200
  • Therefore 12 square meter will cost 200 x 12
  •                                                  = Rs 2400
  • So the cost of painting a rectangular wall will be Rs 2400

**** Price of a commodity is first increased by x% andthen decreased by x%. If the new price is K/100,find the original price.(a) (x - 100)100/K (b) (x2 - 1002)100/K(c) (100 - x)100/K (d) 100K/(1002 - x?)​

Answer»

Answer:

(d)

Step-by-step EXPLANATION:

LET the original price be a.

When it is increased by x%:

= > a + x% of a

= > a(1 + x%)

When decreases by x%:

= > a(1 + x%) - x% of a(1 + x%)

= > a(1 + x%){ 1 - x% }

= > a{1² - (x%)²} {(a+b)(a-b)=a²-b²}

In question, new price is k/100:

= > a(1² - (x²/100)²) = k/100

= > a(100² - x²)/100² = k/100

= > a(100² - x²) = 100²k/100 = 100k

= > a = 100k/(100² - x²)

Original price was 100k/(100² - x²)

Which of following is not irrational? (3+√7) (3-√7) (3+√7) (3-√7) (3√7)

Answer»

Question :- Which of following is not IRRATIONAL ? {(3+√7) (3-√7)} , or (3√7) ?

Solution :-

Solving First we get,

→ {(3+√7) (3-√7)}

using (a + b)(a - b) = (a² - b²) we get,

→ {(3)² - (√7)²}

Now using , (√a)² = a, we get,

→ (9 - 7)

→ 2

→ (2/1)

in the FORM of p/q, where q 0.

Therefore,

{(3+√7) (3-√7)} is a rational Number.

________________

Now, Solving second part :-

→ 3√7

→ 3 * √7

→ 3 can be written as (3/1) , where denominator is not ≠ 0 , so a rational number).

→ √7 is a non perfect natural number . As we know that, any non non perfect natural number is always an irrational number).

Therefore,

(Rational) * (Irrational)

Irrational Number.

Hence, we can conclude that, {(3+√7) (3-√7)} is not an irrational number.

_________________________

Extra :-

  • Rational + irrational = rrational .
  • Rational - irrational = rrational .
  • Rational * irrational = rrational .
  • Rational ÷ irrational = rrational .

__________________________

Note :- { if we assume all parts of questions different, than, all are irrational numbers as TOLD in extra. } .

The sum of number and twice of its consecutive number is 32 .Find the number but but answer in easy way please

Answer»

Numbers = 10 & 22

Step-by-step EXPLANATION:

Given:

  • SUM of number and twice of its consecutive number is 32.

To FIND:

  • What are the TWO numbers ?

Solution: Let the number be x then its consecutive will be x + 1. Therefore,

[ Consecutive numbers : Those numbers which FOLLOW each other in order from smallest to largest. ]

➟ Twice the consecutive no. = 2(x + 1)

➟ Number + consecutive no. = 32

A/q

  • Sum is 32

\implies{\rm } x + 2(x + 1) = 32

\implies{\rm } x + 2x + 2 = 32

\implies{\rm } 3x + 2 = 32

\implies{\rm } 3x = 32 2

\implies{\rm } 3x = 30

\implies{\rm } x = 30/3

\implies{\rm } x = 10

So,

➬ Number is x = 10 and

➬ Consecutive number is 2(10 + 1) = 22
