Let the no. be n

As per given condition n/3 = n/4 + 2n3 - n/4 = 2Take LCM (4n - 3n)/12 = 2n = 2*12 = 24

Number is 24

To prove that sin 30 = 1/2, you could literally construct a right angled triangle ABC. The crudest method is -

Draw an arbitrarily long line.

Mark any point named A on it and use a Protractor to mark of 30 degrees from A and draw another long line.

Mark a point C on the initial line that you drew and again, use the protractor to draw a line that is 90 degrees to AC. Extend the 30 degree line from A and the 90 degree line from C until they meet. Let the point of intersection be B

Measure the ratio of BC/AB and it will be 0.5 or 1/2.

The equation will be

x² + y/4

Sum to infinity = a/(1 - r)

First term = a = 2

Sum = 2/(1 - r)=> 6 = 2/(1 - r)=> 1 - r = 1/3=> r = 2/3.

If A= {a, b, c, d, e, f} B= {c, e, g, h} and C= {a, e, m, n}

(i) AUB = {a, b, c, d, e, f, g, h}(ii) BUC = {a, e, g, h, m, n}(iii) AUC = {a, b, c, d, e, f, m, n}

Given, Total number of eggs = 400

Let number of rotten eggs = x

Then, Probability of getting rotten eggs= x/400

Hence, x/400 = 0.035x = 400*35/1000x = 4*35/10x = 14

Therefore number of rotten eggs are 14

We know, 1kg = 1000g

So, 4kg = 4000g

Ratio of 4kg to 750g

4000 : 750

400 : 75

80 : 15

16 : 3

1 Kg = 1000 gm3.75 kg = 3.75 × 1000 gm = 37503.75 kg : 750 gm3750 : 750375 : 75 25 : 55 : 1

we will use phythagorus theorem

length will be 5+5 cm = 10cm

Sol: (i) Thename of horizontal and vertical linesdrawn to determine the position of any point in the Cartesian plane is x-axis and y-axis respectively. (ii) Thenameof each part of the plane formed by these twolinesx-axis and y-axis is quadrants. (iii) The point where these twolinesintersect iscalled origin.

(1/2) of 60 = 30

Therefore, 30 mangoes are ripe.

Number mangoes that riped = 60 ×1/2 = 30

30 identical mangoes and 4 boysso (30+4-1)C(4-1) ways it can be dividedso 33C3=(33*32*31)/(3*2*1)=5456

Cost of 5 mangoes = Rs. 20 Cost of 1 mango = 20/5 = Rs. 4 Cost of 8 mangoes = 8×4= Rs.32

Hope this will help you. Please select my answer as best answer if you feel so..

c.of.5 mangoes=20rsc.of1 mango =20/5=4rsc.of8 mangoes=8×4=32rsThe cost of 8 mangoes Rs 32. is the best answer

cost of 5 mangoes =20cost of 1 mango=20÷5cost of 8 mangoes =20÷5×8 =32

cost of 5 mangoes = Rs 20 cost of 1 mangoes =Rs ( 20 / 5) = Rs 4

cost of 8 mangoes = Rs ( 8 × 4) = Rs 32

cost of 5 mangoes =20cost of 1 mangoes= 20÷5= 4

cost of 5 mangoes = Rs 20cost of 1 mangoes= Rs (20÷5) = Rs 4cost of 8 mangoes= Rs (8×4) =Rs 32

5 mangoes =201 mango cost=20÷5=4

cost of 5 mangos = 20cost of 1 mango = 20/5=Rs 4cost of 8 mangos=8×4=Rs 32

Cost of 5 mangoes=20Cost of 1 mango=20÷5=4Cost of 8 mangoes=4×8=32

cost of 5 mangoes is 20 cost of 8 mangoes is 32

cost of 5 mangoes is rupees 20 therefore cost of 1 mango = rupees 20/5=4therefore cost of 8 mangoes = 8*4=32 rupees

559500kgs of mango coming to the city.

its incomplete but we can form the equation :-orange costs rs.45 per dozen so, per orange it costs 45/12cost for x oranges=(45/12)x=3.75xcost for y mangos=5ytotal cost= 3.75x+5y

1) 4 is of 30.88 so 1 is of 30.88/4=7.722) 3 is of 55.50 so 1 is of 55.50/3=18.53) 5 is of 47.25 so 1 is of 47.25/5=9.454) 3 is of 14.25 so 1 is of 14.25/3=4.75

CP = 55 PROFIT = 5% SP = 55*1.05 = 57.75

Let equal angles of isosceles triangle be xThen vertex angle is 2x

Using triangle sum propertyx + x + 2x = 1804x = 180x = 45

Angles are 45, 45 and 90

thank you

let the bisectors of the base angles B and C of trianle ABC meet at O.given angle BOC = 135In triangle BOCOBC+BOC+OCB=1801/2B+135+1/2C=1801/2(B+C)=180-135=45B+C=45*2=90-----iIn triangleABCA+B+C=180A=180-(B+C)A=180-90=90A=90Therefore triangle ABC is an right triangle

Do you need the figure for it?

tan A = 4/3We know,tan A = P/B

Using pythagoras theoramH^2 = P^2 + B^2H^2 = 4*4 + 3*3H^2 = 16 + 9 = 25H = 5

Other trigonometric-functionsare:sin A = P/H = 4/5cos A = B/H = 3/5cot A = B/P = 3/4sec A = H/B = 5/3cosec A = H/P = 5/4

thanks jaan

as tan B = 1/cotBso cotB = 5/12
