field of 3.9 mi? 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.
To find the area of each family garden, we can divide the total area of the field by the number of family gardens:
Area of each garden = Total area of field / Number of family gardens
Area of each garden = 3.9 mi² / 1.3 × 10³ gardens
Area of each garden = 3.9 mi² / 1.3 × 10³
Area of each garden = 3.9 mi² / 1.3 × 1000
Area of each garden = 3.9 mi² / 1300
Area of each garden = 0.003 mi²
Therefore, there will be 0.003 square miles in each family garden, which can be written in scientific notation as 3.0 x 10^-3 mi².
