Explain how to change units within the metric system.
Select the best estimate for the measure of the area of the object described. The area of a parcel of land in a large metropolitan area on which a house can be built a. \(900 \mathrm{~cm}^{2}\) b. \(900 \mathrm{~m}^{2}\) c. \(900 \mathrm{ha}\)
Use \(1 \mathrm{mi} \approx 1.6 \mathrm{~km}\) to solve \(-\). Express 50 miles per hour in kilometers per hour.
Use the unit fractions \(\frac{5280 \mathrm{ft}}{1 \mathrm{mi}}, \frac{12 \mathrm{in} .}{1 \mathrm{ft}}\), and \(\frac{2.54 \mathrm{~cm}}{1 \mathrm{in} .}\). Convert \(50 \mathrm{mi}\) to \(\mathrm{km}\).
