A rectangle has a length of (5.1 ± 0.2) m and a width of (2.3 ± 0.1) m. Calculate: (a) the area and (b) the perimeter of the rectangle, Give the uncertainty in each value.
Convert the following measurements to metric units with power-of-ten prefixes. Do not use scientific or engineering notation. Numeric values must range from 1 to less than 1000. Metric prefixes, which are case-sensitive, must be one of the following: M, m, c, k, or µ. (You may use lower-case 'u' in place of 'p'.) Example: 2.00 × 105 m = 200 km Enter the numeric value in the first box, and enter the metric prefix in the second box. a. 3.51 x 10-5 L = b. 7.98 x 108 J = C. -0.000230 W = - W d. 11,200 K = K (note: upper-case 'K' is the abbreviation for the temperature unit 'kelvin')

In the United States, most people measure weight in pounds and height in feet and inches. When weight W is measured in pounds and height h is measured in inches, the BMI formula is BMI = 703W/h². Identify the product that produces the English-to-metric conversion factor of 703. A person with a BMI between 25.0 and 30.0 is considered overweight. If a person is 6'11" tall, for what range of mass mmin ≤ m ≤mmax will he be considered overweight? Mmin = mmax = kg kg
