Initially cut rectangular pan in to two halves.
Then cut each half in half again.
Now total pieces = 4
Now repeat cutting half on other side:
total pieces =8
Now divide each half into another half.
total pieces = 8 x 2 = 16
As can be shown in figure:
Black = first half
pink = dividing each half into another half.

Answer: 7
Step-by-step explanation:
Scientific notation is a method that is used in very large numbers or when we've very small numbers. The number given will be multiplied by its power of 10. In this case,
2.8 trillion = 2,800,000,000,000
= 2.8 × 10^12
0.4 trillion = 400,000,000,000
= 4 × 10^11
Therefore, the times more electricity was there in 1999 than 1950 will be:
= (2.8 × 10^12) / (4 × × 10^11)
= (2.8/4) / (10^12 - 11)
= 0.7 × 10
= 7 times
There were 7 times more electricity that was there in 1999 than 1950.
