Let's analyze the statements one by one:

  1. The expression can be used to find the difference in elevations between Mount McKinley and the Badwater Basin.

    • True; this statement is vague, but it implies that there is a mathematical expression that can be used for the difference.
  2. The expression 20,326 – 282 can be used to find the difference in elevations between Mount McKinley and the Badwater Basin.

    • True; this correctly subtracts the elevation of Badwater Basin (282 feet below sea level) from the elevation of Mount McKinley (20,326 feet above sea level) to find the difference: 20,326 - (-282).
  3. The expression –282 – 20,326 can be used to find the difference in elevations between Mount McKinley and the Badwater Basin.

    • False; this expression inaccurately represents the elevations and does not yield the correct difference.
  4. The elevation for the Badwater Basin can be represented by the rational number -282.

    • True; since the Badwater Basin is below sea level, its elevation is represented as -282 feet.
  5. The difference in elevation between Mount McKinley and the Badwater Basin is 20,608 feet.

    • True; the calculation is as follows: 20,326 (Mount McKinley) - (-282) = 20,326 + 282 = 20,608 feet.
  6. The difference in elevation between Mount McKinley and the Badwater Basin is 20,044 feet.

    • False; as calculated above, the correct difference is 20,608 feet, not 20,044 feet.

In summary, the true statements are:

  • The expression 20,326 – 282 can be used to find the difference in elevations between Mount McKinley and the Badwater Basin.
  • The elevation for the Badwater Basin can be represented by the rational number -282.
  • The difference in elevation between Mount McKinley and the Badwater Basin is 20,608 feet.
