a is answer as 31+4π = 43.5

how

31+4π = 43.5 equivalent to 43

Let E denote the eventof guessing a correct question andEbardenote the eventof not guessing a correct question.Given probability of guessing a certain question is P(E) = (x/2)Hence probability of not guessing answer isP(E bar) = (2/3)P(E) + P(E bar) = 1x / 2 + 2 / 3 = 1x / 2 = 1 / 3∴x = 2/ 3.Hence x = 2/3.

∠ABC = 69°, ∠ACB = 31° [Given]

InΔABC∠ABC + ∠ACB+∠BAC = 180°⇒ ∠BAC = 180° - ∠ABC - ∠ACB⇒ ∠BAC = 180° -69° - 31° = 80°

∠BDC = ∠BAC ( Angle drawn from same chord)

∴ ∠BDC= 80°

the square is inscribed in the circle.Circumference of circle = 2πr650 = 2*22/7*rr = (650*7)/44r = 103.409 mAs the diagonal of the square plot is the diameter of the circle.hence, r× 2 = dso, Diameter = 103.409*2Diameter of circle = 206.818 m = Diagonal of square plotNow,Area of the square plot = 1/2× d²= 1/2× (206.818)²= 1/2× 42773.68Area of the square plot = 21386.84 sq mAnswer.

thanks

option A

suppose a = 1/10

let b = log10[a]

=> log10[1/10] = b=> 1/10 = 10^b

so, the value of b must be -1 hence the value of log10[b] is -ve

can u give explanation

Area of circular road =π(R^2-r^2)Given circumference=2πr=44r=7 m so, R=7+7/2=21/2 m now area of road =22/7 x {(21/2)^2-(7)^2}=22/7 x 35/2 x 7/2 =11 x 35/2 m^2cost =area x rate =11 x 35/2 x 20 =3850 Rs

3850

Option A is the right answer,add all value, take average and divide with 24150 you will get 57.21

option a is correct answer

Option a is correct answer

we find area to calculate paving costcircumference =2pi rr= 22/piarea of circular plot= pi r^2pi× (22/pi)×(22/pi)= 484/pi= 154total cost = 154× 10 = 1540

what?

since line of symmetry divides the line segment into two parts

so, XA = AY = 4cm

again YZ = 6 = YB+BZ but YB = BZ , so YB = BZ = YZ/2 = 3cm

now XZ = XA +AY+YB+BZ = 4+4+3+3 = 14cm

Thnks

Let pure oil = x litres and

other oil = y litres

Profit=20%

Cost of pure oil is Rs. 100x and

Cost of other oil is Rs. 50y.

Total Cost price (CP) = Rs. (100x + 50y)

Now, the shopkeeper sellmixture = (x+y) litres of adulterated oil at the rate of 96 Rs/litres.

Total Sale Price (SP) = 96(x+y) = 96 x + 96y

Profit = SP-CP = [96x+96y] - [100x+50y] = 46y-4x

it's wrong bro

1

option B is the correct answer

(b) is the right ans

cuboid is correct answer.

cuboid is write answer

options b is the correct answer

area =length ×breadth500×30015000

area of rectangle =length *breadth =500*600=300000

3) breadth = 20 mperimeter of rectangle = 2(22+20)= 2×42= 84 m

wrong
