Someone help me with this I’ll mark you as brainliest:)

If a baby uses 15 diapers in 2 days, how many diapers will the baby use in a year?

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

Solve the triangle. a = 21°, c = 105°, c = 5
