One pint of chalkboard paint covers 60 square feet. What is the least number of pints needed to paint the walls of a room in the shape of a rectangular prism with a length of 15 feet a width of 13 feet and a height of 10 feet

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
