Answer 1

Answer:

Step-by-step explanation:

1ft = 12 inches

3 ft 4 inches = 3 * 12 + 4 = 40 inches

36 students

Total Height = 36 * 40 = 1440 inches

Left 34 students

3 feet 3.5 inches = 39.5 inches

39.5 * 34 = 1343 inches

Joined 6

4 feet = 48 inches

48 * 6   =  288 inches

Total students = 36 - 34 + 6  = 8

Total Height = 1440 - 1343  + 288  = 385  inches

Average height = 385/8

= 48.125 inches

= 4 1/18 feet  

= 4 feet 0.125 inch
