Average of 5 numbers= sum of 5 numbers /5Sum of 5 no. = 496x5 = 2480

If two no. are 117 and 140Sum of remaining 3 no. = 2480 - 257= 2223Average of remaining 3 no. = 2223/3= 741

The building is 24m tall

Height of building =15m=1500cmLength of shadow =1.8m=180cmLength of shadow of pole=60cmNow, 1500/180=x/60x=500cmLength of pole =500cm

The height of the lamppost is 4.95

The height of the lamp post is 4.95

required numbers are 3,11

Here, X - Y = 8 X = 8 + Y......(i)Now, A/Q X + 2 = 3Y ( 8 + Y ) + 2= 3Y 10 + Y = 3Y 2Y = 10 Y = 5From (i), X = 8 + Y = 8 + 5 = 13

•°• X = 5, Y = 13

let the smaller number be yand the bigger number be xAcc. to 1st condition x-y=8___(1)and Acc to condition 2ndx+2=3yx-3y=-2___(2)now add eq 1 and (2)..by multipling eq 1 from (_)x-3y=-2___(2)-x+y=-8___(3)

-2y=-10y=5now sub y=5 in eq (1)x-y=8__(1)x-5=8x=13

the two numbers are 13 and 5

x=5 and y=13by the method of linear eqń in two variables

yes a building has 19 m tall

Use this theoremIf opposite angles are equal then opposite sides are equalHere the two sides are equal then angles are equal.A right angled triangle is formed if we draw the picture.One of the angles is 90The sum of the remaining angles = 180-90=90Sum of the angles in a triangle is equal to 180Since the angles are equal the value of the angles are 90/2=45The Sun rays hit the ground at 45.

Find the Hcf of 65 and 117

65 =5*13

117 =3*3*13

--------------------------------------H.C.F. of 65 and 117 = 13

according to question

=>65m -117 = 13

=>65m = 13+117

=>65m =130

=>m =130/65

=>m=2 ANS.

hcf of 117 and 65 is 13 65m-117=1365m=13+11765m=130m=2

thankyou

thankyou soo much

Maximum weight of each bag = HCF(2610, 1980) = 90kgNumber of bags of basmati rice = 2610/90 = 29Number of bags of Indrayani rice = 1980/90 = 22

manisha has 25 bags ofapple.in each bags there are 89 apples.she shared them equal amongst her 6 friends.how many apples each get?are there any apples left.

120 bags of half litre milk can be filled by a machine within 3 minutes find the time to fill such 1800 bags

the answer was 2 is correct

It's a property of parallelogram that opposite angles of a parallelogram are equal.

Therefore , angle A = angle C

3x + 20° = 2x + 70°

3x - 2x = 70° - 20°

x = 50°

Therefore, angle A = angle C = 3 × 50° + 20° = 170°

And angle B = angle D = 180° - 170° = 10°

Hence, 170° and 10° are the angles.

One block weighs 31/4 kgthen 10 blocks will weigh31/4*10310/407.75kg

Let the larger number = xThen the square of the smaller number = 8 times the larger number = 8xand the square of the larger numbe r = xAccording to the question,x - 8x = 180=> x - 8x - 180 = 0=> x - 18x + 10x - 180 = 0=> x(x - 18) + 10(x - 18) = 0=> (x - 18) (x + 10) = 0=> x - 18 = 0 or x + 10 = 0=> x = 18 or x = -10Thus, the larger number = 18 or -10Then, the square of the smaller number = 8(18) or 8(-10)= 144 or -80The square of a number can't be negative, so, the square of smaller number = 144Hence, the smaller number = sqrt(144) = 12The numbers are 12 and 18

thanks for answer

Rs. paise 9. 50+14. 60 24 10

24Rs 10p

109 × 893 = 97337(first class)238 × 542 = 128996 (economy)

total money paid = 97337 + 128996 =226,333 rupees.

passenger flying first class =97337passenger flying at the economy =128996

Cost of first class fare=Rs. 893Cost of economy class fare=Rs. 542

Number of first class passengers=109Number of economy class passengers=238

Money paid by first class passengers to the airline=109×Rs.893=Rs.97337

Money paid by economy class passengers to the airline=238×Rs.542=Rs.128996

∴Total money paid to airline=Rs.(97337+128996)=Rs.226333

Given a - b = 0.9ab = 0.36

(1) (a - b)^2 = a^2 + b^2 - 2ab0.9*0.9 = a^2 + b^2 - 2*.36a^2 + b^2 =.72 +. 81a^2 + b^2 = 1.53

(a + b)^2 = a^2 + b^2 + 2ab(a + b)^2 = 1.53 + 2*.36(a + b)^2 = 1.53 +.72(a + b)^2 = 2.25(a + b) = 1.5

(2) a^2 - b^2 = (a + b)(a - b) = 1.5*0.9 = 1.35
