Question

sinθ + sin²θ/1 + cosθ + cos2θ = tanθ

Explanation:

SIN(2θ) = 2sinθcos θ

cos(2θ) = 2cos2θ − 1

tanθ = sinθcosθ

Therefore,

LHS = (sinθ+sin2θ/(1+cosθ+cos2θ)

= (sinθ+2sinθcosθ)/(1+cosθ+2cos2θ−1)

= sinθ(1+2cosθ) / cosθ(1+2cosθ)

= tanθ

= RHS

There WOULD be a 10% loss, if rice is sold at Rs. 54 per kg. To earn a profit of 20%, the price of rice per kg will be

Rs. 65

Rs. 70

Rs. 63

Rs. 72

Correct Option: D

Here , S.P. of rice per kg = Rs. 54

∴ C.P. of rice per kg =

54 × 100

= Rs. 60

90

For 20% profit,

S.P. per kg. =

60 × 120

= Rs. 72

100

Using the given formula :

Here , Loss% = 10%

C.P. = S.P. 100

100 - Loss%

C.P. = 54 100

100 - 10

C.P. = Rs. 60

New S.P. = C.P. 100 + Profit%

100

New S.P. = 60 × 100 + 20 = $ 72

Answer:

10%

Step-by-step EXPLANATION:

Answer:

20

Given A = 1852.20, P = 1600, R = 5%.

We know that A = P(1 + r/100)^n =

1852.20 = 1600(1 + 5/100)^n

1852.20 = 1600(105/100)^n

1852.20 = 1600(1.05)^n

1852.20/1600 = (1.05)^n

1.157625 = (1.05)^n

(1.05)^3 = (1.05)^n

n = 3.

Therefore in 3 years the rupees 1600 amount to rupees 1852.20 at 5% P.A.

Answer:

43m meters of fencing is required to enclose a RECTANGULAR vegetable garden 15 m LONG and 6.5 m wide.

Step-by-step explanation:

Perimeter of the given garden= 2(L + b)

=> Perimeter = 2(15m X 6.5m)

=> Perimeter = 2 x 21.5m = 43m

so, Required fencing = 43m

To clear all his dues, he should pay the outstanding Rs. 1,683/- at the END of 3rd year.

Given :-

● The DISTANCE between it's parallel side = 19cm

● The two parallel sides are 27cm and 23CM

SOLUTION :-

Here ,

We have to calculate ,

The area of Trapezium

As we know that,

Area of trapezium = 1/2 * ( a + b) * h

Here,

HEIGHT of the trapezium( Distance) = 19cm

Parallel sides of trapezium are 27 and 23cm

Put the required values in the given formula

Therefore,

Area of trapezium = 1/2 * ( 27 + 23 ) * 19

Area of trapezium = 1/2 * 50 * 19

Area of trapezium = 25 * 19

Area of trapezium = 475cm^2

Hence, The area of trapezium is 475cm^2

● Trapezium is a quadrilateral which. having two sides parallel.

Some more quadrilaterals are :-

● SQUARE is also a quadrilateral which having four sides equal and opposite sides parallel

Area of square = side * side

● Parallelogram is also a quadrilateral which having opposite sides parallel and equal

Area of parallelogram = base * height
