Answer»

DON'T WORRY!!!!

let one digit be X

and other digit be y

x + y = 8

10y + x -( 10x + y) = 18

-9x + 9y = 18

-x + y = 2

equating both equations,

x + y = 8

-x + y = 2

the -x and x get cancelled

so, y + y= 8 + 2(the + symbol is USED, since both x were of DIFFERENT SIGNS)

2y = 10

y= 5

x + y = 8

x + 5 = 8

x= 8-5 => x= 3

so, x = 3

and y = 5

also, 53 -35 = 18

3 + 5 = 8

so, answer is option c)

What will be the remainder when p(x)=x^49 + 61 is divided by (x-1)

Answer»

Answer:

Remainder = 62

Step-by-step explanation:

X - 1 = 0

x = 1

p(x)=x^49 + 61

      = (1)^49 + 61

      = 1 + 61

      = 62

∴ Remainder = 62

How many perfect squares between 100 and 121

Answer»

ANSWER:

For what value of k, are the roots of the quadratic equation (k – 12) x2 + 2(k – 12) x + 2 = 0 equal?

Answer»

Step-by-step EXPLANATION:

ANSWER: a = k – 12, b = 2 (k – 12), c = 2

∴ D = b2 – 4ac = [2(k– 12)]2

– 4(k – 12) X 2

= 4 (k – 12)2 – 8 (k– 12)

ROOTS are equal, if D = 0

⇒ 4 (k – 12) 2 – 8 (k – 12) = 0

⇒ 4(k – 12)(k – 12 – 2) = 0

⇒ (k – 12) (k – 14) = 0

⇒ k = 12 or 14

But k = 12 does not satisfy the eqn.

k = 14 Ans.

19. Three cubes of metal with edges 3 cm, 4 cm and 5 cm respectively aremelted to form a single cube. Find the lateral surface area of the newcube formed.​

Answer»

Given :

  • Three cubes of metal with edges 3 cm , 4 cm & 5 cm respectively are melted to form of SINGLE cube.

To find :

  • Lateral surface area of the NEW cube formed.

Solution :

  • EDGE of 1st cube = 3 cm
  • Edge of 2nd cube = 4 cm
  • Edge of 3rd cube = 5 cm

Formula Used :-

{\boxed{\bold{Volume\:of\:cube=Edge^3}}}

Then,

\sf{Volume_{\:1st\:cube}=3^3\:cm^3}

\to\sf{Volume_{\:1st\:cube}=27\:cm^3}

\sf{Volume_{\:2nd\:cube}=4^3\:cm^3}

\to\sf{Volume_{\:2nd\:cube}=64\:cm^3}

\sf{Volume_{\:3rd\:cube}=5^3\:cm^3}

\to\sf{Volume_{\:3rd\:cube}=125\:cm^3}

Then,

Total volume of 3 cubes ,

= (27+64+125) cm³

= 216 cm³

3 cubes are melted to from a single cube.

Consider,

  • Edge of new single cube = R cm

Volume of new single cube = cm³

A/Q,

\to\sf{R^3=216}

\to\sf{R^3=6^3}

\to\sf{R=6}

Lateral surface area of new cube ,

= 4 × edge²

= 4 × 6² cm²

= 144 cm²

Therefore,the lateral surface area of the new cube is 144 cm² .

X/a+y/b-2=0ax-by+(b**2-a**2)​

Answer»

ANSWER:

Answer:

x = a, \: y = b

Step-by-step explanation:

Given \: pair \: of \: Linear \\equations:

\frac{x}{a}-\frac{y}{b}=0\\\implies \frac{bx-ay}{AB}=0\\\implies bx-ay = 0 \:---(1)

and\: ax+by=a^{2}+b^{2}\:---(2)

/* MULTIPLY equation (1) by b, equation (2) by a, we get

b^{2}x-aby = 0 \:---(3)

a^{2}x+aby=a(a^{2}+b^{2})\:---(4)

/* Add equations (3) and (4),we get

x(a^{2}+b^{2})=a(a^{2}+b^{2})

\implies x = \frac{a(a^{2}+b^{2})}{(a^{2}+b^{2})}

\implies x = a

Put \: x = a \: in \: equation \\(1),\: we \: get

ab-ay = 0

\implies b-y = 0

\implies y = b

Therefore,.

x = a, y=b
