6 times 2 is 12.

12 is the answer.

Answer:

x= 70°, y=40°

Step-by-step explanation:

2x=140

x= 70

y= 180-140= 40

140 + y = 180

y = 180 - 140

y = 40

2x + 40 = 180 (Angle Sum Property)

2x = 180 - 40

2x = 140

x = 140/2

x = 70

X = 70

Y = 40

Step-by-step explanation:

Formula of perimeter =

Length + Length + Breadth + Breadth

So,

Step-by-step explanation:

Answer:

400 m^2.

Step-by-step explanation:

The largest  area is obtained where the enclosure is a square.

I think that's the right answer because a square is a special form of a rectangle.

So the square would be 20 * 20  = 400 m^2.

Proof:

Let the  sides of the rectangle be x and y m long

The area A = xy.

Also the perimeter  2x + 2y = 80

x + y = 40

y = 40 - x.

So substituting for y in A = xy:-

A = x(40 - x)

A = 40x - x^2

For maximum value of A  we find the derivative and equate it to 0:

derivative A' =  40 - 2x = 0

2x = 40

x = 20.

So y = 40 - x

= 40 - 20

=20  

x and y are the same value so x = y.

Therefore for maximum area the rectangle is a square.

The largest area of rectangle will be 400 square meters.

Let us consider the length and breadth of rectangle is x and y respectively.

Perimeter of rectangle is given that 80 meters.

                                  [tex]2x+2y=80\\\\x+y=40\\\\y=40-x[/tex]

 Area of rectangle is,

                                        [tex]=x*y\\\\=x*(40-x)\\\\A=40x-x^{2}[/tex]

  For maximum area, differentiate Area with respect to x  and equate with zero.

                           [tex]\frac{dA}{dx} =\frac{d}{dx}(40x-x^{2} ) \\\\\frac{dA}{dx} =40-2x=0\\\\x=40/2=20m[/tex]

       So,    [tex]y=40-20=20m[/tex]

Area  = [tex]20*20=400m^{2}[/tex]

Thus, The largest area of rectangle will be 400 square meters.

Step-by-step explanation:

Let the acres of land on which pea is to be cultivated is "X" acres and the acres of land on which tomato is to be cultivated is "Y"

It is given that number acres of tomatoes planted must not be more then twice the number of acres of peas planted

Thus, [tex]Y < 2X[/tex]

[tex]X + Y = 12[/tex] acres

[tex]Y = 12-X[/tex] acres

Thus,

[tex]12 - X \leq X\\12\leq 2X\\6 \leq X[/tex]

Let us take X = 6 , Then Y = 13-6 = 6

Answer:

The volume of the cylinder ≅ 197.82[tex]cm^{2}[/tex]

Step-by-step explanation:

The volume of a cylinder is equal to the area of the base times the height. We know the radius, therefore we can find the area of the base. The formula for the volume of the cylinder is as follows:

V = π[tex]r^{2}[/tex][tex]h[/tex]

(now substitute the values of "r" and "h", and get...)

V = π[tex]r^{2}[/tex][tex]h[/tex]

[tex]V = (3^{2} )(7)[/tex] x π

V = (9)(7)π

V = 63π

V ≅ 197.82[tex]cm^{2}[/tex]
