A field of 3.9 square miles is being subdivided into 1.3×10^3 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 need to divide the total area of the field (3.9 square miles) by the number of family gardens (1.3×10^3).
3.9 square miles divided by 1.3×10^3 family gardens is equal to:
3.9 ÷ (1.3×10^3) = 3.9 ÷ 1.3 × 10^(-3) = 3 × 10^(-3) square miles.
Therefore, each family garden will have an area of 3 × 10^(-3) square miles.
To find the number of square miles in each garden, we divide the total area of the field (3.9 square miles) by the number of gardens (1.3×10^3).
Dividing 3.9 by 1.3 gives us 3.
Since the units are square miles, the answer is 3 square miles.
Expressing this answer in scientific notation, we have 3.0×10^0 square miles.
To get the number of square miles in each garden, you need to divide the total area of the field by the number of gardens.
The total area of the field is 3.9 square miles.
The number of gardens is given as 1.3×10^3.
To divide, you divide the total area by the number of gardens:
3.9 square miles ÷ 1.3×10^3 gardens
To divide by 1.3×10^3, you can first divide by 1.3 and then multiply by 10^3.
So, 3.9 ÷ 1.3 = 3.
To multiply by 10^3, you move the decimal point 3 places to the right, which gives you 3000.
Therefore, each garden will have an area of 3000 square miles.
To express this answer in scientific notation, you can write it as 3.0×10^3 square miles.
