Answer:
Step-by-step explanation:
Let s represent the length of the short piece. Then the long piece is 6s+8, and the total length is ...
s +(6s+8) = 99
7s = 91 . . . . . . . . subtract 8, collect terms
s = 13 . . . . . . . . . divide by 7
99 -13 = 86 = 6(13)+8 . . . length of long piece
The short piece is 13 feet long; the long piece is 86 feet long.

5 BTUs/ft^3
Step-by-step explanation:
800 BTUs * 30 students = 24000 total BTUs combined
Volume of room = 20 feet * 20 feet * 12 feet = 4800 cubic feet
BTUs/ft^3 = 24000 BTUs / 4800 cubic feet = 5 BTUs/ft^3
So the amount of BTUs per cubic foot that were produced was 5 BTUs/ft^3
