Answer:
6 minutes
Step-by-step explanation:
'a' in the formula represents altitude in feet. You are told the altitude is 21000 feet, so put that into the formula:
21000 = 3400t +600
You can solve this for t:
20400 = 3400t . . . . . subtract 600 from both sides
6 = t . . . . . . . . . . . . . . . divide both sides by 3400
The problem statement tells you that t represents minutes after lift off, so this solution means the altitude is 21000 feet 6 minutes after lift off.
The question is asking for the number of minutes after lift off that the plane reaches an altitude of 21000 feet, so this answers the question directly:
The plane is at an altitude of 21000 feet 6 minutes after lift off.
Answer:
$378,000
Step-by-step explanation:
The computation of the bad debt expense for the year is shown below:
Bad debt expense = Outstanding account receivable × estimated percentage given - credit balance of allowance for doubtful account
= $6,500,000 × 0.06 - $12,000
= $390,000 - $12,000
= $378,000
We simply deduct the credit balance from the estimated balance so that the correct amount could arrive
