Final answer:
The correct maximum landing weight for a CRJ 700 is not provided in the options as it is 67,000 pounds. The importance of using the right representation for measurements, such as decimal or scientific notation, is highlighted.
Step-by-step explanation:
The maximum landing weight for a CRJ 700 aircraft is actually 67,000 pounds (30,391 kilograms). However, since this option is not provided in the multiple-choice answers, it suggests there might be a discrepancy with the numbers or a requirement for a specific variant of the CRJ 700 series. It's important to consult the aircraft's specific documentation for accurate data.
Regarding numbers in measurements, they can be expressed in different formats, such as decimal form or scientific notation. For instance, the maximum takeoff weight of a Boeing 777-200ER can be represented as 298,000 kilograms or in scientific notation as 2.98 × 105 kg. Similarly, the mass of an average mosquito, a much smaller figure, can be written as 0.0000025 kilograms, showing the versatility of measurement representations in providing clarity regardless of scale.
