2 Agro square and a rectangle house equal area Ifeach side of the Square is 18 cm and the widthof the rectangle is 12 cm find the bngth of therectangle.​

Answer»

ANSWER:

Breadth of rectangle is 27 cm

Step-by-step EXPLANATION:

LET breadth of rectangle be x

Side of agro Square house= 18 cm

Area of Agro Square house= (side)²

(18)²= 324 cm²

Length of Rectangle house= 12 cm

Area of Rectangle= l× b

324 cm² = 12cm × x

324cm² / 12 cm = x

27 cm= x or x = 27 cm

A bag contains 8 white and 6 black balls. A ball is drawn at random from the bag, its colour is observed and kept aside (ie, not returned in the bag). Three additional balls of the same colour as observed are put in the bag. If now two balls are drawn simultaneously at random from the bag, then the probability that these two balls are of different colours, is:​

Answer»

Given : A bag contains 8 white and 6 black balls.

A ball is DRAWN at random from the bag, its colour is OBSERVED and kept aside (ie, not returned in the bag).

Three additional balls of the same colour as observed are put in the bag.

now two balls are drawn simultaneously at random from the bag,  

To Find :  the probability that these two balls are of DIFFERENT COLOURS

7/25

2/5

18/35

4/15

Solution:

White = 8

Black = 6

Total = 14

case 1  : White taken out probability  = 8/14   =  4/7

Now   white = 8 - 1  + 3  =  10

Black = 6

Total = 16

WB   +  BW

= (10/16)(6/15)  + (6/16)(10/15)

= 120/240

= 1/2

Probability = (4/7) (1/2)  =  2/7

case 2  : black taken out probability  = 6/14   =  3/7

Now   black = 6 - 1  + 3  =  8

White = 8

Total = 16

WB   +  BW

= (8/16)(8/15)  + (8/16)(8/15)

= 128/240

=  8/15

Probability = (3/7) (8/15)  =  8/35

2/7 + 8/35

= (10 + 8)/35

= 18/35

18/35 is the probability

Find the median of the following data: 21, 14, 6, 29, 18, 13, 19, 30, 9, and 12?

Answer»

Answer:

First of all, we need to arrange the data in an ascending order. Thus, the data is PRESENTED below as:

15, 35, 43, 46, 48, 49, 50, 55

N = 8

Since the number of items in the series is even, thus the following formula is used to calculate the median.

Median=

SIZE of (

\cos( \frac{\pi}{7} )  \times  \cos( \frac{2\pi}{7} )  \times  \cos( \frac{4\pi}{7} )

Solution ⤵️

\cos( \frac{\pi}{7} )  \times  \cos( \frac{2\pi}{7} )  \times  \cos( \frac{4\pi}{7} )

\implies \cos(20. \frac{\pi}{7} )  \times  \cos( {2}^{1}. \frac{\pi}{7}  )  \times  \cos( {2}^{2} . \frac{\pi}{7} )

\implies  \frac{ \sin {2}^{3} ( \frac{\pi}{7} ) }{ {2}^{} . \sin \frac{\pi}{7}  }

( \because  \{ \cos(a). \cos(2a)... \cos( {2}^{n - 1}a ) =  \frac{ \sin( {2}^{n} a) }{ {2}^{n}  \sin a \: }

\frac{ \sin(8 \frac{\pi}{7} ) }{8. \sin( \frac{\pi}{7} ) }  =  \frac{ \sin(\pi +  \frac{\pi}{7} ) }{8. \sin( \frac{\pi}{7} ) }

\frac{ \sin(8 \frac{\pi}{7} ) }{8. \sin( \frac{\pi}{7} ) }  =  \frac{  \sin(\pi +  \frac{\pi}{7} ) }{8. \sin( \frac{\pi}{7} ) }  =  \frac{ -  \sin( \frac{\pi}{7} ) }{8. \sin( \frac{\pi}{7} ) }

Y= sin²x then dy/dx is ?1. sinx2. 2sinx3. 2sinxcosx4.cosx​

Answer»

Answer:

You would use the CHAIN rule to solve this. To do that, you'll have to determine what the "outer" function is and what the "inner" function composed in the outer function is.

In this case,

sin(x)

is the inner function that is composed as PART of the

sin2(x).

So, mathematically, the chain rule is:

F'(x)=f'(g(x))(g'(x)) where g(x) is inner function and f(g(x)) is outer one.

1) The derivative of the outer function(with the inside function LEFT alone) is:

f'((sin(x))^2) = 2sin(x)

2) The derivative of the inner function:

g'(sin(x)) =cos(x)

Combining the two steps through multiplication to get the derivative as :

2sin(x)cos(x).

What happens to the force between two objects, if(i) the mass of one object is doubled ?(ii) the distance between the objects is doubles and tripled ?(iii) the masses of both objects are doubled ?​

Answer»

Hello Brainly user!!

I hope this may help u in your studies .

⋆❥ǫᴜᵉՏㄒɨօຖ⋆

What happens to the force between two objects, if

(i) the MASS of one object is doubled ?

Ans (i) If the mass of one of the objects is doubled, then the force of gravity between them is doubled. Since gravitational force is inversely proportional to the square of the separation distance between the two interacting objects, more separation distance will result in WEAKER gravitational forces.

(ii) the distance between the objects is doubled and tripled ?

Ans (ii) If the distance between the two objects is tripled, then THUS, the gravitational force between the two objects becomes one-ninth. (iii) If the masses of both the objects are doubled, then Thus, the gravitational force between the two objects becomes 4 times.

(iii) the masses of both objects are doubled ?

Ans (iii) If the mass of both of the objects is doubled, then the force of gravity between them is QUADRUPLED; and so on. Since gravitational force is inversely proportional to the square of the separation distance between the two interacting objects, more separation distance will result in weaker gravitational forces.

If the ratio of measure of two adjacent angles of a parallelogram is 1:2 find the measure of all angles of the parallelogram

Answer»

Answer:

In a parallelogram, adjacent ANGLES are SUPPLEMENTARY and OPPOSITE angles are equal

so

1X + 2x = 180°

3x = 180°

x = 180°/3 = 60°

1x = 60°

2x = 2 x 60° = 120°

as the opposite angles of the parallelogram are equal

the measures of all the angles are : 60°, 120° , 60°, 120°
