The wool of a vicuna is finer than any other wool. the hair of this animal can be as thin as 0.000006 meters. if the average thickness of human hair is approximately 8.4 × 10-5 meters, what is the difference of the thickness of a human hair and a vicuna hair? a. 2.4 × 10-5 meters b. 2.4 × 10-6 meters c. 7.8 × 10-6 meters d. 7.8 × 10-5 meters re

The boiling point of water at an elevation of 0 feet is 212 degrees fahrenheit (°f). for every 1,000 feet of increase in elevation, the boiling point of water decreases by about 2°f. which of the following represents this relationship if b is the boiling point of water at an elevation of e thousand feet? a) e = 2b - 212 b) b = 2e - 212 c) e = -2b + 212 d) b = -2e + 212
