You will have to divide 1392 from 29 to get ANSWERS
and the ANSWER is 48

If 3 smiles=10grins
then,1smile=10/3=3.33

and 6 GRINS =9 laughes
then,1grin=9/6=1.5

therefore,2 smiles=6.66 grins
and6.66 grins=6.66*1.5=9.99 or approax 10 laughs

therefore 10 laughs TAKE to equal 2 smiles..

The nth TERM. The 'nth' term is a formula with 'n' in it which ENABLES you to find any term of a SEQUENCE without having to go up from one term to the next. 'n' stands for the term number so to find the 50th term we WOULD just substitute 50 in the formula in PLACE of 'n'.

The associative property states that you can ADD or multiply REGARDLESS of how the numbers are GROUPED. By 'grouped' we mean 'how you use parenthesis'. In other words, if you are ADDING or multiplying it does not matter where you put the parenthesis. Add some parenthesis any where you like!.

AB || DC and AD = BC.

Extend the sides AD and BC till E and F as SHOWN.  

As AB and CD are two parallel lines and AD intersects them both, the angles D and EAB are same.  But angle EAB = 180 - A.  so,

             angle D = 180 - A

Similarly, the line BC intersects parallel lines AB and DC, so

           angle C = angle FBA = 180 - B 

Now, draw perpendiculars from D and C onto AB meeting AB at G and H respectively.  

     Since AB || DC, the sides DG || CH.  

               Also,  DG = CH = distance between the parallel lines.

Looking at the triangles DGA and CHB, we find that

            DG = CH,    AD = BC (GIVEN),  angle G = angle H  = 90°.

  Δ DGA and Δ CHB are congruent.  Hence angle A = angle B.

     So, angle C = 180 - angle A = 180 - angle B = angle

5 + 2√3 ) / ( 7 + 4√3 )

= ( 5 + 2√3 ) / ( 7 + 4√3 ) × ( 7 – 4√3 ) / ( 7 – 4√3 )

= ( 5 + 2√3 ) ( 7 – 4√3 ) / [ ( 7)² – ( 4√3)² ]

= [ 5 ( 7 – 4√3 ) + 2√3 ( 7 – 4√3 ) ] / ( 49 – 48 )

In parallelogram ABCD, two points P and Q are taken on diagonal BD such that DP = BQ.
To Prove: (i) ∆APD ≅ ∆CQB
(ii)     AP = CQ
(iii)    ∆AQB ≅ ∆CPD
(IV)    AQ = CP
(v)     APCQ is a parallelogram.
Construction: Join AC to intersect BD at O.
Proof: (i) In ∆APD and ∆CQB,

∵ AD || BC
| Opposite sides of parallelogram ABCD and a transversal BD intersects them
∴ ∠ADB = ∠CBD
| Alternate interior angles
⇒ ∠ADP = ∠CBQ    ...(1)
DP = BQ    | Given (2)
AD = CB    ...(3)
| Opposite sides of ||gm ABCD In view of (1), (2) and (3)
∆APD ≅ ∆CQB
| SAS CONGRUENCE criterion
(ii)    ∵ ∆APD ≅ ∆CQB
| Proved in (i) above
∴ AP = CQ    | C.P.C.T.
(iii)    In ∆AQB and ∆CPD,
∵ AB || CD
| Opposite sides of ||gm ABCD and a transversal BD intersects them
∴ ∠ABD = ∠CDB
| Alternate interior angles
⇒ ∠ABQ = ∠CDP
QB = PD    | Given
AB = CD
| Opp. sides of || gm ABCD
∴ ∆AQB ≅ ∆CPD | SAS Congruence Rule
(iv) ∵    ∆AQB = ∆CPD
| Proved in (iii) above
∴ AQ = CP    | C.P.C.T.
(v)    ∵ The diagonals of a parallelogram bisect each other.




∴ OB = OD
∴ OB - BQ = OD - DP
| ∵ BQ = DP (given)
∴ OQ = OP    ...(1)
Also, OA = OC    ...(2)
| ∵ Diagonals of a || gm bisect each other
In view of (1) and (2), APCQ is a parallelogram.

AD=AC
So ANGLE ACD=angle ADC
Now angle ADC =angle ABD +angle BAD
So angle angle ADC > angle ABD
angle ACD > angle ABD
AB>AC

Tan X = √(sec² x - 1) = √{(SEC x + 1)(sec x - 1)}
so,LHS= tan x/(sec x - 1) =√{(sec x + 1)(sec x - 1)}/(sec x - 1)
=√{(sec x + 1)/(sec x - 1)}
=(sec x + 1)/√(sec²x -1)
=(sec x + 1)/tan x

RHS = tan x + sec x + 1/tan x + sec x - 1
= (tan²x+sec²x+1+2tan x sec x+2tan x +2sec x)/(tan²x+sec²x+2tan x sec x - 1)
=(2sec²x+2tan x sec x + 2tan x + 2sec x)/(2tan²x + 2tan x sec x)
=(sec x (1+sec x) + tan x ( 1 + sec x))/{tan x (tan x + sec x)}
=(sec x + 1)/tan x
so, LHS=RHS [SHOWED.]
[P.S.: Theta is denoted with "x" here.]

When TWO Triangles are congruent they will have exactly the same three sides and exactly the same three ANGLES. The equal sides and angles may not be in the same POSITION.

Let the maximum MARKS be a

Passing mark = 36 % of a

Passing mark = 36A/100

=> 123 + 39 = 36a/100

=> 162 = 36a / 100

=> a = 16200 / 36

=> a = 450

Maximum marks = 450

If each interior is 150 degrees, then each EXTERIOR ANGLE is 180–150 or 30 degrees. Hence the polygon has 360/30 = 12 SIDES. There will be 54 diagonals.

Hii There!!!!

WEIGHT of each bag = 4 KG 500 G = 4.5 kg
Capacity of the van = Not more than 800 kg

Number of BOXES that can be loaded = 800 / 4.5 = 8000 / 45 = 177.77

Therefore, number of boxes that can be loaded in the van is not more than 177.


Hope it helps

Speed = 72 - (-63) = 135 KMPH

because they are going in OPPOSITE directions speed will add

distance = 810 KM

tine = distance / speed = 810 / 135 = 6 hours
