x=105/7

x=15

last TWO OBSERVATIONS are 2x+5 and 2x+9

=14+5 and 14+9

mean=42/2=21

Angle A = angle B (bcoz it's an isosceles trapezium)
even angle C =angle D
You can APPLY the same reason
ACCORDING TO TRAPEZIUM PROPERTY THE SUM OF ADJACENT ANGLES IN A TRAPEZIUM ARE EQUAL i.e., angle A=angle D
angle B=angle C

Hey
_________

circumference of CIRCLE =2πr
2πr =44
2×22/7×r =44
44/7r =44
r = 44×7/44
r=7 cm

hence, RADIUS =7cm

So LET the LARGER one be X and ANOTHER be y
x-y=3
X=3+y
now
1/X -1/y = 3/28
1/3+y -1/y =3/28
y-3-y/y^2+3y=3/28
3y^2+9y+84=0
y^2+3y+28=0
y^2+7y-4y+28=0
y(y+7)-4(y+7)=0
(y+7)(y-4)=0
y=-7 or 4
negative VALUE DISCARD as natural no. is given
so smaller no. is 4
and larger no. is 3+4=7

ANYONE can SAY

1 HOUR = RS 7.20

Convert the FRACTION into decimal:

18 1/2 hour = 18.5 hour

Find the pay:

1 hour = Rs 7.20

18.5 hour = 7.5 x 18.5 = Rs 133.20

Total NUMBER of shoes 20
Out of 20 shoes 2 can be selected in C(20,2)ways
We want 2 matching shoes.
First MAKE 2 matching shoes as 1 unit.
Now there are 10 units
Out of 10 units 1 unit can selected in C(10,1) WAYS.
PROBABILITY OF SELECTING 2 MATCHING SHOES =C(10,1)/C(20,2)=10/190=1/19

SPEED of the train = 80kmph  

Speed INCREASED to = 120kmph

Hii !!



It seems something is wrong in the question.



DC = 100 cm , it should be 10 cm.

ABCD is a rectangle, in which

AD = 12 cm, DF = 10 cm , BE = 7 cm and AB = 18 cm.

As we know that opposite sides are always equal.

So,

AD = BC = 12 cm and AB = DC = 18 cm.

Length of rectangle = 18 cm

And,

Breadth of rectangle = 12 cm

Therefore,

Area of rectangle = L × B = 18 × 12 = 216 cm².

BC = 12 cm and BE = 7 cm

Therefore,

EC = BC - BE = 12 - 7 =5 cm.

And,

DC = 18 cm , DF = 10 cm

Therefore,

FC = DC - DD = 18 - 10 = 8 cm.

-------------------------------------------

As we can see that ∆ ADF , ∆ECF , ∆ABE are right angled triangle .

Therefore,

Area of ∆ADF = 1/2 × AD × DF

Area of ∆ADF = 1/2 × 12 × 10 = 60 cm²

Area of ∆ECF = 1 /2 × EC × FC

Area of ∆ ECF = 1/2 × 8 × 5 = 20 cm².

And,

Area of ∆ABE = 1/2 × AB × BE

Area of ∆ ABE = 1/2 × 18 × 7 = 56 cm².

Therefore,

Area of the shared region = Area of rectangle - (area of ∆ ADF + area of ∆ ECF + Area of ∆ ABE )

=> [ 216 - ( 60 + 20 + 56 ) ] cm².

=> [ 216 - ( 136 ) ] cm².

=> ( 216 - 136 ) cm².

=> 80 cm².

Bhai ye to BATAO KYA PROOF krna H

This LIMIT is discontinuous at X=0
Because lim F(x)=1
x-0+
& lim f(x)=-1
x-0-
So this limit does not EXIST.

We know that,
(Slant HEIGHT) ^2 = (Height)^2 + (Base)^2
=> l^2 = h^2+B^2
=> (41)^2 = (40)^2 + b^2
=> 1681 = 1600 + b^2
=> 1681-1600 = b^2
=> b = root81
=> b = 9 cm

To find how much lace is REQUIRED we have to find out the PERIMETER
= 2(l+b)
= 2(3+2)
= 2(5)
= 10 m

so 10 m lace is required

According to the question,

Let the required TWO numbers are x and ( x - 3 ),

Given, the difference of their RECIPROCALS is 3 / 28.

Reciprocal of x = 1 / x

Reciprocal of x - 3 = 1 / ( x - 3 )

⇒ Difference = 3 / 28

⇒ x^2 - 3x - 28 = 0

⇒ x^2 - ( 7 - 4 )x - 28 = 0

⇒ x^2 - 7x + 4x - 28 = 0

⇒ x( x - 7 ) + 4( x - 7 ) = 0

⇒ ( x - 7 )( x + 4 ) = 0

⇒ x = 7 or - 4

Given that the required numbers are NATURAL numbers, so they can't be negative.

∴ x = 7

Other NUMBER = x - 3 = 7 - 3 = 4

Therefore, required natural numbers are 7 and 4 .
