Final answer:
The Challenger 650's maximum take-off weight is closest to 50,000 lbs (option B), and measurements like this can be represented using decimal form or scientific notation for ease of understanding or conversion.
Step-by-step explanation:
The Challenger 650 has a maximum take-off weight of 48,200 lbs, which would be closest to option B. 50,000 lbs. Numbers in measurements, such as weight and mass, can be represented in various ways. For instance, using decimal form or scientific notation. Scientific notation is especially useful for very large or very small numbers to make them easier to work with. For example, the maximum takeoff weight of a Challenger 650 is easier to comprehend when given as a whole number, but an immensely large or small value, like the mass of a mosquito, which is around 0.0000025 kilograms, is more easily understood when written in scientific notation as 2.5 x 10-6 kg.
To demonstrate the use of unit conversions, we can see that tons, pounds, and ounces are all units of mass that can be converted into each other. For example, 3.5 tons is equivalent to 7000 pounds since 1 ton equals 2000 pounds.
