area=( (80*729)+244)/729
      = 58564/729 sqm
length of each side= sqrt(58564/729)
                              = 242/27

(3root18+2root12) (root50-root27)

Answer»

Hi ,

( 3√18 + 2√12 ) ( √50 - √27 )

= [ 3√(3×3×2)+2√(2×2×3)][(√(5×5×2)-√(3×3×3) ]

= ( 9√2 + 4√3 ) ( 5√2 - 3√3 )

= 9√2( 5√2 - 3√3 )+4√3( 5√2 - 3√3 )

= 90 - 27√6 + 20√6 - 36

= 54 - 7√6

a two digit number is 3 more than 4 times the sum of its digits if 18 is added to the number the digits are reversed find the number

Answer»

Let the ones place digit be a

And UNIT place digit be B

According to first condition,

10a + b = 4 ( a+ b) + 3

=> 10a + b = 4a + 4b + 3

=> 10a - 4a + b - 4b = 3

=> 6a - 3b = 3

=> 2a - b = 1 --------(1)

According to second condition,

10a +b + 18 = 10b + a

=> 10a + b - 10b - a = - 18

=> 9a - 9b = - 18

=> a - b = - 2 ------(2)

On SUBTRACTING EQUATION 2 from 1, we get

2a - b - a + b = 1 - (-2)

=> a = 3

On Substituting the value of a in equation (2), we get

3 - b = - 2

=> b = 5

Required number = 10a + b

= 10 × 3 + 5

= 30 + 5

= 35

Two dice of different colours are thrown simultaneously. The probability that the sum of the faces appeared is either 7 or 11 is?up vote0down votefavoriteThe options are: (A) 7/36 (B) 1/9 (C)2/3 (D) 5/9

Answer» DICE are usually marked from 1 to 6

The POSSIBLE sums are from 2 to 12

The total numbers of sums = 36

In the sums, 7 APPEARS 6 TIMES, while 11 appears 2 times

Probability = No. of desired outcomes/Total No. of possible outcome


Probability of getting a sum of 7 or 11 = 8/36

                                                             = 2/9

ALTERNATIVELY

Probability of getting sum of 7 = 6/36 = 1/6

Probability of getting sum of 11 = 2/36 = 1/18


Probability of getting sum of 7 or 11 = 1/6  + 1/18

                                                         = 2/9


NOTE:

As can be seen from the calculations above, none of the choices given is correct.

Solve for x and y 1.5x + 0.1y =6.2 and 3x - 0.4y=11.2

Answer»

Given 1.5x + 0.1y = 6.2
3x - 0.4y = 11.2
Multiplying 2 in EQN 1
3x + 0.2y = 12.4
3x - 0.4y = 11.2
Subtracting both
we get 0.6y = 1.2 => y = 1.2/0.6 = 2
and putting y in eqn 1 we get 1.5x = 6.2 - 0.2
1.5x = 6 => X = 4 So solution of your question is x = 4 and y = 2

Y=(4x-1)^1/2 find dy/dx

Answer»

The answer is given below :

RULE :

d/dx (x^N)

= n x^(n - 1)

SOLUTION :

Given,

y = (4X - 1)^(1/2)

Now, differentiating both sides with respect to x, we get

dy/dx = 1/2 × (4x - 1)^(1/2 - 1) × d/dx (4x - 1)

= 1/2 × (4x - 1)^(-1/2) × 4

= 2 × (4x - 1)^(-1/2)

= 2/{√(4x - 1)}

Now , alpha^4 x beta^4 + alpha^3 x beta^3 can be ALSO WRITTEN as
(alpha x beta)^4 + (alpha x beta)^3.
As we know that the SUM of two zeroes is 3 , now subtitute 3 in the place of alpha x beta.

how to use arrow method , if 12 labourers can earn RS 12240 in 12 days.how many labourers can earn RS 6800 in 8 days?

Answer»

Hey friend!!!!

your ANSWER is "10"

Explaination=>
___________

First we have to find wages for WORK done by one MAN in one day.

12 man in 12 days gets 12240.

So 1 man in 1 day = 12240/(12*12)=85

Now “N” men in 8 days = N*85*8 which is given as 6800.

N=6800/(85*8)

N=10
