A field of 3.9 mi2 is being subdivided into 1.3×103 family gardens. How many square miles will there be in each garden? Write the answer in scientific notation.(1 point)

Answer 1

To find the number of square miles in each garden, we need to divide the total area of the field by the number of gardens.

Total area = 3.9 mi^2
Number of gardens = 1.3×10^3

Area per garden = Total area / Number of gardens
= 3.9 mi^2 / (1.3×10^3)

To write the answer in scientific notation, we divide 3.9 by 1.3 and keep the same power of 10.

Area per garden = (3.9/1.3) mi^2 * (10^0)
= 3 mi^2 * (10^0)

Therefore, the area per garden is 3 mi^2.

Answer 2

Charlee is using her calculator to find the product of two large numbers. Her calculator shows 1.78E12 on the display. Interpret what this means. (2 points)

Answer 3

The number 1.78E12 can be interpreted as 1.78 multiplied by 10 raised to the power of 12. In other words, it represents a very large number in scientific notation. Specifically, it means that the actual number is 1,780,000,000,000, or 1.78 trillion.
