Area of triangle=(1/2)*base*height36=(1/2)*base*6BC=12cm

Let the cost price be Rs. xSelling Price=Rs.4x/3

Gain=Rs.{(4x/3)-x}=Rs. x/3

∴Gain percent=(Gain/Cost Price)×100={(x/3)/x}×100=33.33%

24 chairs= 9255.60 rs each = 9255.60/24= 385.65 rs

Answer = 385.65 rs

no. of chairs=24total cost = 9255.60 RS.cost of each chair = total cost /no. of chairs=(9255.60/24)rs.=385.65 Rs.hence the cost of each chair 385.65 rs.

Perimeter= 2(7x+3x)200=20xx= 10mlength = 70mbreadth = 30mAnswer:-

Let the length and breadth of the basketball court be 7x and 3x units respectively.Given:-Perimeter of the court=200 m

∴2(7x + 3x)=200=>20x=200=>x=10

∴Its length=7x=70 m and breadth=3x=30 m.

we know 1 km = 1000m

therefore, 2 km= 2000 m

200m:2km= 200:2000= 1:10

thank you

Median in equilateral triangle is perpendicular bisector of the side.when side is a cm, then length of median will bex =√[(a)²-(a/2)²] =√(3a²/4) =(a/2)√3⇒x = (a/2)√3⇒a = 2x/√3

now. area = (√3/4)a² = (√3/4)×(2x/√3)² = x²/√3 cm²

I think 3rd.............

Let the angles be a-d,a,a+daccording to the question a+d = 2(a-d)a-d+a+a+d = 180 (since sum of the angles are 180 degrees )= 3a = 180= a = 60from second equation 3d = 60 d = 20so the angles are 40 60 and 80

SOLUTION:CASE ILet initial cost price be x Rs.Profit = 20/100 * x = x/5So selling price = x + x/5 = 6x/5

CASE IICost price = x + 50Selling Price = 6x/5 + 30Profit = (6x/5 + 30) - (x + 50) = x/5 -20Profit Percentage = (x/5 - 20) / (x + 50) * 100But in according to the question profit percentage = 20 - 10/3 = 50/3 %So (x/5 - 20) / (x + 50) * 100 = 50/3∴ (x/5 - 20) / (x + 50) = 1/6∴ 6x/5 - 120 = x + 50∴ x/5 = 170∴ x = 850So original cost price = Rs 850

Let the length and breadth of the basketball court be 7x and 3x units respectively.Given:-Perimeter of the court=200 m

∴2(7x + 3x)=200=>20x=200=>x=10

∴Its length=7x=70 m and breadth=3x=30 m.

Area 1/area 2 = (length 1/length 2)²

40/area 2 = (1a/3a)²

area 2 = 40 / (1/3)²

= 40 * 3²

= 360

2 A = 3 B = 6 C

B = 2/3 A,C = 2/6 A = 1/3 A

We know thatSum of interior angles of a triangle are 180°

A + B + C =180

A + 2/3 A + 1/3 A = 180°

2 A = 180

A = 90°

Divisor*Quotient+Remainder= Divident

g(x)(x-2)+(-2x+4)=x³-3x²+x+2

g(x)(x-2)=x³-3x²+x+2+2x-4

g(x)(x-2)=x³-3x²+3x-2

g(x)=x³-3x²+3x-2/(x-2)

g(x)=(x²-x+1)(x-2)/(x-2)

g(x)=x²-x+1

Image of point A( 5,-3)under reflection P(-1,3) will be(5-1,-3+3)(4,0)x coordinate decrease by 1 and y coordinates increase by 3

please elaborate

Length*distance between longer sides = breadth* distance between shorter sides=> 15*4= 8*distance between shorter sides=> Distance between shorter sides = 7.5 cm

17. Ratio is 3:1

Wrong

Which step you found error?

105 × 106

( 100 + 5) ( 100 + 6)

100² + 600 + 500 + 30

100,00 + 1130

11,130

Any other way to solve it

We know that triangle can be made only sum of two sides is greater than third sides.here (5+1)cm = 6cm < 8 cmwo triangle is not possible

thank you very much

5+1=6<8sum of two sides of triangle is less than the third sideso the triangle is not possible

there are 4 letter and they distinct sopossible permutations is 4! = 24

No it is not possible bcoz the sum of two sides is not greater than the third side.....of the triangle5+1<8

No it is not possible bcoz the sum of two sides is not greater than the third side.....of the triangle5+1<8

The greatest side must be < rest sides sumif 8 > 5+1 then triangle is impossible

no your contradiction is wrong plz check my question clearly
