Answer:
35 feet of ribbon.
Step-by-step explanation:
The rate of 14 inches per every 2 minutes would equal 30 two-minute intervals as 60 minutes (an hour)/2 minutes = 30. 14 x 30 = 420 inches in one hour, which reduces to 35 feet since 420inches/12 inches (one foot) = 35.

Answer:
D
Step-by-step explanation:
Start by writing out w in terms of x. After one year, there is 1.08*x dollars in the account. x dollars are then deposited, giving us a total of 1.08*x + x (normally we would simplify this to 2.08 but looking at the answers this is not a good idea.) Next, multiply by 1.08 to account for the 2nd year's interest. This brings to total to w = 1.08(1.08*x + x) = (1.08^2)*x + 1.08*x. Factoring out x, we are left with w = (1.08^2 + 1.08) * x. Dividing both sides by (1.08^2 + 1.08), we are left with x = w/(1.08^2 + 1.08) so the answer is d.
