If a=17 and b=12 what is the value
of a-b

182

Step-by-step-explanation:

10a + b

a=17

b=12

10(17) + 12

10x17 + 12

170 + 12

182

5

Step-by-step explanation:

Solving

Step 1: Plug in the variables.

Step 2: Subtract 12 from 17.

Therefore, the answer is 5.

Have a lovely rest of your day/night, and good luck with your assignments! ♡

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

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.

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.
