Based on the equation, what is the approximate length of a reptile that has a mass of 20.5 grams?
O A 62 cm
B. 66 cm
C. 70 cm
D. 75 cm

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
