Metric Conversions for TEAS 7

Correct Answer: B

Rationale: The correct answer is B: France. The metric system was developed in France during the French Revolution in the late 18th century. The French Academy of Sciences proposed the system to standardize measurements for scientific and commercial purposes. France played a significant role in promoting and spreading the use of the metric system worldwide. Germany (A), Italy (C), and Spain (D) did not have a direct role in the development of the metric system.

Correct Answer: A

Rationale: To find the result of multiplying 0.15 by 60, we simply multiply the two numbers. 0.15 x 60 = 9. This is because when you multiply a decimal by a whole number, you multiply as if the decimal point isn't there and then adjust the decimal point in the final answer. Therefore, the correct answer is A: 9. Choice B (15) is incorrect as it would be the result of multiplying 0.15 by 100. Choice C (45) is incorrect as it would be the result of multiplying 0.15 by 300. Choice D (60) is incorrect as it would be the result of multiplying 1 by 60.

Correct Answer: A

Rationale: The correct answer is A: G. The prefix "giga" represents 10^9 in the International System of Units (SI). The symbol for "giga" is a capital letter G. It is used to denote a factor of one billion. Choice B, m, represents the prefix "milli" which is 10^-3. Choice C, Gg, is not a standard representation of the prefix "giga." Choice D, g, represents the unit of mass "gram," not the prefix "giga." Therefore, the correct notation for the prefix "giga" is A: G.

Correct Answer: A

Rationale: Certainly! To express 10^6 m in simpler terms, we need to convert meters to kilometers. 1 kilometer is equal to 1000 meters. Therefore, 10^6 m = 1,000,000 m = 1 km. Option A is correct because 1 kilometer is the equivalent of 10^6 meters. Options B, C, and D are incorrect because they represent larger units of measurement than meters. Megameter is 1,000,000 meters, gigameter is 1,000,000,000 meters, and terameter is 1,000,000,000,000 meters, making them larger than 10^6 meters.
