Show all work for full marks. 1. State the most appropriate metric measurement unit for the following: [1] a) Depth of the snow __ b) Distance to California __ 2. Describe a situation where a referent could be useful to measure an object. [1] 3. To estimate a length in inches, which personal referent would be the most useful? [1] 4. Convert the following Round your answers to the nearest tenth of a unit. [6] a) 9ft3in=cm d) 146mi= b) 6200000mm=km c) 21m=yd c) 32miles=km f) 1247.14cm=ydsldots ft.

## Step 1: Appropriate Metric Units### a) The depth of snow is typically measured in centimeters (cm) or meters (m) if it's very deep.### b) The distance to California is best measured in kilometers (km).## Step 2: Referent Usefulness### A referent is useful when a standard measuring tool isn't available. For example, if you need to estimate the length of a table and don't have a ruler, you could use your hand span as a referent. Knowing your hand span is approximately 8 inches, you could estimate the table's length by counting how many hand spans it covers.## Step 3: Personal Referent for Inches### A thumb width is approximately one inch and is a useful personal referent for estimating lengths in inches.## Step 4: Conversions### a) Conversion of feet and inches to centimeters: First convert 9 ft to inches: . Total inches: . Convert to cm: .### b) Conversion of millimeters to kilometers: .### c) Conversion of meters to yards: .### d) Conversion of miles to kilometers: .### e) Conversion of miles to kilometers: .### f) Conversion of centimeters to yards and feet: . Since there are 3 feet in a yard, .
