Assume we have 6 apple pies and we divide them in to 6 pieces. Bob eats 4 pieces of pie, John eats 7 pieces of pie, and Sue its 2 pieces of pie. If you are very hungry and want to eat a whole pie yourself, how much will be left over? Express your answer as a mixed number.
If we 6 pieces divided into six pieces that equals 36 total pieces. Bob eats 4 pieces. 36-4 = 32 John eats 7 32-7=25 Sue eats 2 25-2 = 23 You want a whole pie which is 6 pieces. 23-6 = 17 pieces There are 17 pieces of pie left, but we have to express the answer in a mixed number. The correct answer is 2 5/6 apple pies left.
If Retail Company A sells 125 widgets at $2.20 per widget for the month of May, what would be the correct month end journal entry to correctly record the sale of the widgets? Answer this assuming that there is no sales tax and that no sales were made on credit. A) Debit Accounts Receivable $275 Credit Accounts Payable $275 B) Debit Cash $275 Credit Revenue/Sales $275 C) Debit Revenue/Sales $275 Credit Accounts Payable $275 D) Debit Dividends $275 Credit Cash $275
Answer is B 125 widgets times $2.20 per widget is $275. Since Company A does not make sales on credit there would be no receivables or payables. We also are not worried about sales tax in this problem. So we would increase our cash with a debit and increase our sales with a credit.
Factor the expression 8x^2 + 16x - 64.
The first step is to factor out an 8 from the expression. 1) 8x^2 + 16x - 64 = 8(x^2 + 2x - 8) The next step is to write out all of the factors of 8 2) 8 and 1, 2 and 4 Then we see which two factors could we add or subtract to come to the middle term coefficient. We can subtract 4 and 2 to come to the middle term coefficient of 2. So we need a positive 4 and a negative 2 coefficient. We also keep the 8 outside the parenthesis. Answer: 8(x+4)(x-2)
