Melanie has a piece of cloth 12 1/3 yd long. how many 3/4 yd pieces can be cut from the cloth? a. 17 pieces b. 12 pieces c. 16 pieces d. 15 pieces

Step-by-step answer

P Answered by PhD

To find how many total pieces she can cut, you need to divide the total length of the piece she has by the length of the piece she wants to cut:

12 1/3 / 3/4

Convert the total length to an improper fraction:
12 1/3 = 37/3

Now you have 37/3 / 3/4

When dividing two fractions, flip the second one over and multiply the two top numbers and the two bottom numbers:

37/3 x 4/3 = 37x4 / 3x3 = 148 / 9 = 16.44, which rounds down to 16.

The answer is C.

Shehata Coffee Shop calculated the NET value of its accounts receivable as of December 31, 2019, to be $179,000, based on an aging schedule of accounts receivable. Shehata has also provided the following information: The gross accounts receivable balance on December 31, 2019 was $191,800. Actual uncollectible accounts receivable written off during 2019 totaled $13,400. The Allowance for Uncollectible Accounts balance on January 1, 2019 was $17,800. Required: Part 1: What account(s) and for what $ value(s) would appear on the Balance Sheet? Part

Step-by-step answer

P Answered by PhD

1. The preparation of balance sheet is shown below:-

2. $8,400

Explanation:

1 Balance sheet

December 31, 2019

Assets Amount

Current assets

Accounts receivables $191,800

Allowance for uncollectible accounts ($12,800)

Net accounts receivables $179,000

Working note:-

Net accounts receivables = $179,000

Gross accounts receivables = $191,800

Allowance for uncollectible accounts, December 31, 2019 = Gross accounts receivables - Net accounts receivables

= $191,800 - $179,000

= $12,800

2. Bad debt expense = Allowance for uncollectible accounts, December 31, 2019 - (Allowance for uncollectible accounts, January 1, 2019 - Uncollectible accounts written off during 2019)

= $12,800 - ($17,800 - $13,400)

= $12,800 - $4,400

= $8,400

27.calculate the change in freezing point when 116.8 grams of barium chloride are added to 250 grams of water. kf = 1.86°c/m; kb = 0.512°c/m a. -4.17°c b. -12.5°c c. -8.35°c d. 0°c

Step-by-step answer

P Answered by PhD

Freezing point depression, ΔT, is calculated using the formula:

ΔT= - Kf * molal

Where molal is the molality of the solute (moles solute/kg solvent)

In this case the solute is Barium Chloride while the solvent is Water. The formula for molality is:

molal = (mass of solute / molar mass solute) / (mass of solvent)

molal = (116.8 g / 208.23 g/mol) / (0.25 kg Water) =

molal= 2.24 mol/kg = 2.24 m

Substituting to the 1st equation:

ΔT= - 1.86 °C/m (2.24 m)

ΔT= -4.17 °C

So the answer is A.

Which statement is true? A. – 17 –20 B. 12=84 C. 8.01 8.001 D. −23 –6

Step-by-step answer

P Answered by PhD

A. -17 > -20

Step-by-step explanation:

The statement states that -17 is greater than -20. This is true. By definition of the rule of negatives, the larger the number attached to the negative, the smaller the number is.

Select the correct text in the passage. Which sentence in this except from Mark Twain's The Adventures of Tom Sawyer shows Tom to be resourceful? Monday morning found Tom Sawyer miserable. Monday morning always found him so-because it began another week's slow suffering In school. He generally began that day with wishing he had had no intervening holiday, it made the going into captivity and fetters again so much more odious. Tom lay thinking. Presently it occurred to him that he wished he was sick; then he could stay home from school. Here was a vague possibility. He canvassed his system. No allment was found, and he investigated again. This time he thought he could detect colicky symptoms, and he began to encourage them with considerable hope. But they soon grew feeble, and presently dled wholly away. He reflected further. Suddenly h discovered something. One of his upper front teeth was loose. This was lucky; he was about to begin to groan, as a "starter," as he called it, when it occurred to him that if he came into court with that argument, his aunt would pull it out, and that would hurt. So he thought he would hold the tooth In reserve for the present, and seek further. Nothing offered for some little time, and then he remembered hearing the doctor tell about a certain thing that laid up a patient for two or three weeks and threatened to make him lose a finger. So the boy eagerly drew his sore toe from under the sheet and held it up for Inspection. But now he did not know the necessary symptoms. However, it seemed well worthwhile to chance it, so he fell to groaning with considerable spirit.
