Answer:

Tetrahedron generally known as triangular pyramid consists of 4 triangular faces, 6 edges and 4 vertices. The base of the tetrahedron is a triangle. All the vertices have the same atom that is bonded to the central metal atom which lies in the centre of the tetrahedron. We take  as an example to see how the atoms actually bond in tetrahedron.  It is quite visible from the image that 4 O-atoms lies on all the 4 vertices and 1 Si-atom lie in the centre.

Please help Determine whether y varies directly with x. If so, find the constant of variation k and write the equation.
dsp73
The linear equation:
y = k x + b
We will use first two values and solve the system of equations:
11 = k * 7 + b   / *(-1)
13 = k * 8 + b
 ---------------------
 -11 = - k * 7 - b
  13 =   k * 8 + b
----------------------
   2 = k       
   13 = 16 + b 
    b = 13 - 16 = -3
   y = 2 x - 3 ( y varies directly with x )

You need to split it in half then multply then add
Harrizon [31]

Answer:

130^2 or 130 meters squared

Step-by-step explanation:

I decomposed the figure, then found the area of the decomposed figures then found the sum of them.

FIGURE A:

3 x 3 = 9

= 9^2

FIGURE B:

11 x 11 = 121

= 121 meters^2

So 121 + 9 = 130

= 130 meters^2

REMEMBER!!!!

THE FORMULA FOR AREA IS LENGTH * WIDTH = AREA
