Answer»

Answer:

1

Step-by-step EXPLANATION:

X^(p-q)  can be WRITTEN as x^p/x^q

so 1/(x^(p-q) +1)   can be written as x^q /(x^p+x^q)

so x^p/(x^p+x^q)   + x^q /(x^p+x^q) = (x^p+x^q)/(x^p+x^q) =1

Raju gave 2 /5 part of money to dev and 3 /10 part to salami. Now he has only 180 rs. How much rs raju had at beginning​

Answer»

Step-by-step EXPLANATION:

let \: raju \: had \: rs \: x \: in \: beginning \\ therefore \\  \frac{2}{5} x +  \frac{3}{10} x  +  180 = x \\  \frac{4x + 3x}{10}   + 180 = x \\ 7x  +  1800 = 10x \\ 1800 = 3x \\ x = 600 \\ therefore \: raju \: had \: 600  \: rupees \: initially

The area of the right triangle is184 cm sq one one of it's leg is 16 cm long.find the length of the other leg.

Answer»

ANSWER:

Step-by-step explanation:

LET the one leg be=base=16cm

area=1/2×b×h

184=1/2×16×h

8h=184

h=184/8

h=23

so the height (perpendicular)=23cm

(hypotenuse)2=p2+b2

=SQUARE root (23×23+16×16)

=square root (785)

=28.01cm

therefore, H=28.01cm

P=23cm

5.

Show that 2 + 3√2 is not irrational no given that √2 is an irrational no

Answer»

Step-by-step explanation:

let the assume 2 +3√2 is rational no

so, 2 +3√3 in the FORM of p/q therefore, 2 +3√2 = a/b (where a or b≠0)

= 3√2 = a/b - 2

= 3√2 = (a-2b)/b

= √2 = (a-2b)/3b

but √2 is a irrational no

then, (a-2b)/3b is a irrational no

so, our ASSUMPTION is WRONG

2+3√2 is a irrational no

The sum of three consecutive number is 46 . Find the number

Answer»

Answer:

43/3, 46/3, 49/3

Step-by-step EXPLANATION:

Let the three numbers be

  • X
  • x + 1
  • x + 2

Given, The sum of three consecutive number is 46

⇒ x + ( x + 1) + (x + 2) = 46

⇒ 3x + 3 = 46

⇒ 3x = 46 - 3

⇒ 3x = 43

⇒ x = 43/3

This RESULTS in a rational number. If we have to go with this only, then the numbers are 43/3, 46/3, 49/3

========================================

Furthermore, If question was The sum of four consecutive number is 46 . Find the numbers

Let the four numbers be

  • x
  • x + 1
  • x + 2
  • x + 3

Given, The sum of four consecutive number is 46

⇒ x + ( x + 1) + (x + 2) + (x +3) = 46

⇒ 4x + 6= 46

⇒ 4x = 46 - 6

⇒ 4x = 40

⇒ x = 10

The numbers are 10,11, 12, 13

The measure of the angles of a pentagon are (-5).(-6), (2x - 7),xº and (2x - 2)°. Find thevalue of x​

Answer»

ANSWER:

Step-by-step EXPLANATION:

sum of angles of a PENTAGON =540degrees

x-5+x-6+2x-7+x+2x-2=540

x+x+2x+2x-20=540

7x-20=540

7x= 540+20

Simplify the following : (8-4/3 /2-2)1/2 .....

Answer»

3 1/3 ÷ 5/3 - 1/10 of 2 ½ + 7/4

= (3 × 3 + 1)/3 ÷ 5/3 – 1/10 of (2 × 2 + 1)/2 + 7/4

= 10/3 ÷ 5/3 - 1/10 of 5/2 + 7/4

                     [‘of’ simplified]

= 10/3 × 3/5 – ½ × ½ + 7/4                  [‘÷’ simplified]

= 2/1 - ¼ + 7/4                   [‘×’ simplified]

= (2 × 4)/1 × 4) - (1 × 1)/4 × 1) + (7 × 1)/4 × 1)

= 8/4 - ¼ + 7/4

[Now the DENOMINATORS are same of all the fractions]

= (8 – 1 + 7)/4                  [‘+’ and ‘-‘ simplified]

= 14/4

= 7/2

√05.10√49..Find the value​

Answer»

Answer:

GIVEN a-b=5_________(1)

also a2+b2=49

we KNOW that :-

a2+b2=(a+b)(a-b)

49=(a+b)(5)

a+b=49/5___________(2)

from eqn 1 we have

a=5+b

now PUTTING the value of a in eqn 2 we get

5+b+b=49/5

2b=49/5-5

2b=24/5

b=24/5×1/2

b=12/5

therefore a=5+b=5+12/5=37/5

therfore answer a=37/5 and b=12/5

Verification given a-b=5

therfore 37/5-12/5=25/5=5 Hence verified.

18. Find the quadratic polynomial, whosezeroes are in the ratio 2:3 and their sumis 15​

Answer»

RATIO of the zero of the polynomial is 2:3.

Let X be multiply to both the numbers.

Then the zero becomes 2X and 3X.

According to question,

2X + 3X = 15

5X = 15

X = 15/5

X = 3.

Therefore,

One ZEROS = 2X = 2 × 3 = 6

And,

The another zero = 3X = 3 × 3 = 9

Let alpha = 9 and Beta = 6.

Sum of zeros = (Alpha + Beta) = (9+6) =15

Product of zeros = (Alpha × Beta) = 9 × 6 = 54

Therefore,

QUADRATIC POLYNOMIAL = X²-(Alpha + Beta)X + Alpha × Beta.

=> X²-(15X) + 54

=> X²-15X+54

Hence,

The Quadratic polynomial = X²-15x+54
