Answer 1

1. 0.0000006709 in scientific notation is 6.709 x 10^-7.

2. 9,085,000,000,000 in scientific notation is 9.085 x 10^12.

3. 2.09 x 10^5 in decimal notation is 209,000.

4. 1.98E8 in scientific notation on paper is 198,000,000.

5. To find the size of each lot in scientific notation, we divide the area (3.2 square miles) by the number of lots (1.6 x 10^3).
The calculation is:
3.2 / (1.6 x 10^3) = 2 x 10^-3
So, each lot will be 2 x 10^-3 square miles in size.
