Answer:

We need to put 120 yards of fence around the pool.

Step-by-step explanation:

Given that, The length and breadth of the rectangle pool are 40 and 20 yards.

We need to put fence around the pool. The measure of the fence will be equal to the perimeter of the pool. The formula for the perimeter of the rectangle is

Here l is the length; b is the breadth.

On substituting the values, we get the perimeter of the rectangle.

Therefore, Perimeter .

So, we need to put 120 yards of fence around the pool.

Answer:

A(x) = (24 -2x)√(6(x -6))

Step-by-step explanation:

Heron's formula for the area of a triangle in terms of sides a, b, and c is ...

A = √(s(s -a)(s -b)(s -c))

where s is the semi-perimeter.

Here, we have s = 24/2 = 12, and a = b = x, c = 24-2x. So, the area is ...

A = √(12(12 -x)(12 -x)(12 -(24 -2x)) = (12 -x)√(12(2x -12))

A = 2(12 -x)√(6(x -6))

Answer:

600 x 60 = 36,000

50 x 50 = 2,500

1,000 x 3 = 3,000

70 x 80 = 5,600

100 x 300 = 30,000

20 x 40 = 800

90 x 90 = 8,100

9 x 900 = 8,100

500 x 300 = 150,000

1,000 x 5 = 5,000

125 - 100

770 - 800

364 - 400

Answer:

Option A ( -3/2 , $\frac{-3\sqrt{3} }{2}$ )

Step-by-step explanation:

According to Question, The Spinner Rotate 600* Thus after Completing 360* it Comes Exactly Where It Started . Now again rotate It 180* .

Now We Are on ( -X axis ) & Completed 360*+180*=540* Rotation

Now After Rotate It 60* More we come in Third Quadrant & Here In Third Quadrant Only Tangent & Cotangent Is Positive .(Sine & Cosine is Negative)

(For Diagram, Please Find in attachment)

Now In Triangle OAB

Cos60* = OA / OB

1/2 = -X / 3 Thus X= -3/2

Sin60* = AB / OB

$\sqrt{3}$ /2 = -Y / 3 Thus Y = - $\sqrt{3}$ * 3 /2
