side = 13/3so area of a square is 13/3*13/3169/9 m^2

thanks

Option (2) is correct.

√243 = √81.3 = 9√3

√48 = √16.3 = 4√3

√75 = √25.3 = 5√3

15√3+20√3-9√326√3

25+√75+√27=25+√5×5×3+√3×3×3=25+5√3+3√3=25+8√3

25+ 8√ 3 is the correct answer of the given question

25+V75+V27=25+V5x5x3+V3x3x3=25+V5x5x3+V3x3x3=25+5V3+3V3=25+8V3

25+8√3 is right answer of this question.

25+V75+V27=25+V5x5x3+V3x3x3=25+5V3+3V3=25+8V3

can you tell 4 and 5

isme area of circle minus kyu karenge

√3/2= √6/2

3.75 ÷ 1000

= (375/100) ÷ 1000

= 375 / 100000

= .00375

centre is (-g, -f)=(3,1)

Area of square = 4² = 16Area of circle = 3.14×2² = 12.56Probability = 12.56/16 = 1.27

The denominator of both the variables should be same for the equation to represent circle

=> L/3 = 1/4=> L = 3/4

Given : a cone and hemisphere have equal bases and equal volume.volume of cone is equal to the volume of hemisphere, let height of cone is a and hemisphere is b1/3 π r² a =2/3π r² bπr² had cancleda/b =2/13 and 3 had cancled it meansratio of height is 2:1

(5)^x+3 = (25)^3x-4

(5)^x+3 = (5)^6x-8

As base are same so power should be equalx + 3 = 6x - 86x - x = 3 + 85x = 11x = 11/5

try to do it by your self

The horizontal angle between true meridian and magnetic meridian, is known

magnetic declination

If the plane of the scale of the dip circle is not in the magnetic meridian, then the needle will not indicate the correct direction of earth's magnetic field. The angle made by the needle with the horizontal is known as themagnetic dip.

thanks

1/sinθ - sinθ = a^3(1 - sin²θ)/sinθ = a^3cos²θ / sinθ = a^3

similarlysin²θ / cosθ = b^3

thena^4 b^2 + a^2 b^4= [cos²θ/sinθ]^(4/3) [sin²θ / cosθ]^(2/3) + [cos²θ/sinθ]^(2/3) [sin²θ / cosθ]^(4/3)

= (cosθ)^(8/3) / (cosθ)^(2/3) + (sinθ)^(8/3) / (sinθ)^(2/3)

= cos²θ + sin²θ= 1

Formula of n th term in AP = a+(n-1)d

Where a is the first term

n is the term number

d is the common ratio

Now when n = 7

So,a+(7-1)d=a+6d

When n = 3

So, a+(3-1)d=a+2d

Since we are given that the ratio of 7th to 3rd term of an AP is 12:5

⇒(a + 6d)/(a + 2d) = 12/5

⇒5a+30d=12a+24d

⇒6d = 7a

⇒a=6d/7

Now 13th term =a+(13-1)d =a+12d = 6d/7 + 12d

4th term =a+(4-1)d =a+3d = 6d/7 + 3d

Now ratio of 13th and 4th term

(6d/7 + 12d)/(6d/7 + 3d)= (6d + 84)/(6d + 21d)= 90d/27d= 10/3= 10:3

Thus the ratio of the 13th and 4th term is 10:3

For AP nth term isTn = a + (n-1)d

Where,a = first termd = common difference

T7 = a + 6dT3 = a + 2d

T7/T3 = 12/5a + 6d/a + 2d = 12/55(a + 6d) = 12(a + 2d)5a + 30d = 12a + 24d12a - 5a = 30d - 24d7a = 6da = (6/7)d

Ratio of 13th to 4th termT13/T4 = a + 12d/a + 3d

Put value of a = (6/7)dT13/T4 = (6/7)d + 12d/(6/7)d + 3dT13/T4 = 90d/27d = 10/3

Ans :- The total surface area of the remaining solid will be 18 cm²

Step-by-step explanation:

The outer surface area of the cylinder = 2πrh

= 2 x 3.14 x 0.7 x 2.4

= 10.55 cm²

slant height of the cone, L = √(h² + r²)

=√(2.4² + 0.7²)

= √6.25

= 2.5 cm

hence outer surface area of the cone = πrL

= 3.14 x 0.7 x 2.5

= 5.5 cm²

This outer surface area of the cone is equal to the inner surface area of the hollow portion of the cylinder left.

surface area of the cylindrical base = πr²

= 3.14 x 0.7²

= 1.54 cm²

Hence total surface area of the remaining solid = The outer surface area of the cylinder + inner surface area of the hollow portion of the cylinder left + surface area of the cylindrical base

= 10.55 + 5.5 + 1.54

= 17.59 cm²

= 18 cm² (rounded off to nearest cm²)

Hence the total surface area of the remaining solid will be 18 cm²

= {3,4,9,17,33}

is the answer

can you plz solve it further plz

SP=390gain=20%so CP=390/1.2=325

let the CP be Rs. 100 and MP be Rs. xgain % after discount = 12%gain = 12% of 100 = Rs. 12⇒SP of the article = CP + Gain = Rs. (100 + 12) = Rs. 112Discount % = 20%Discount = 20% of Marked Price= Rs.20/100 * x = Rs. 20x/100 = Rs. x/5as da question saysmarked Price - discount = SP=> x - x/5 = 112=> (5x - x)/5 = 112=> 4x/5 = 112=> x = 112 * 5/4 = Rs. 140marked Price = Rs. 140amount marked above the CP = MP - CP = Rs. (140 - 100) = Rs. 40

∴% amount marked above the CP= Amount increased/CP * 100= 40/100 * 100= 40%
