Answer:

Step-by-step explanation:

Given ABCD is a parallelogram

To prove ⇒ AC trisects BD, and BD bisects AC.

Proof ⇒ Since coordinates of points A, B, C and D have been given in the diagram. If we prove that midpoint of AC and BD are common then AC and BD will equally bisect each other.

Midpoint of AC = (\frac{x+x'}{2},\frac{y+y'}{2})

coordinates of A and C are (0,0) and (2a + 2b, 2c)

Now mid point  E=(\frac{2a+2b+0}{2},\frac{2c+0}{2})

                             = [(a+b),c]

Now mid point of BD =(\frac{2b+2a}{2},\frac{2c+0}{2})

                                   = [(b+a), c]

It proves that midpoints of AC and BD are common.

So AC trisects BD and BD bisects AC.

The recipe makes 8 pancakes.
He wants to make 12 pancakes.

First, find out how many times what he needs is compared to the recipe.

He wants 12 pancakes; the recipe makes 8 pancakes.

12/8 = 1.5

He wants to make 1.5 times the recipe.

Now multiply every ingredient amount by 1.5 to find what he needs to make 12 pancakes.

240 g of plain flour.
240 g * 1.5 = 360 g of plain flour

2 egs
2 eggs * 1.5 = 3 eggs

600 ml milk
600 ml * 1.5 = 900 ml

Answer: 360; 3; 900
