21 is a rational number because it is an integer, which can be converted into a fraction.

<u>Step-by-step explanation:</u>

When a denominater and numerator are integers and gives a quotient then it is a rational number.

21/1, where 21 is denominator and 1 is numerator the quotient is 21. Therefore 21 is a rational number which can also be considered as a ratio.

Heidi's Accessories bought 50 necklaces for $10 each on account. The invoice included a 6% sales tax and payment terms of 2/10,
garri49 [273]

Answer:

<u>The correct answer is B. Accounts payable for US$ 53.oo</u>

Step-by-step explanation:

1. Let's recall what is the Journal entry when a company return part of the inventory previously purchased:

Debit

The amount Heidi's accessories owed to the supplier would have been sitting as a credit on the accounts payable account because the invoice has not been payed. In the case of this return, we should debit it because we should diminish the amount due.

Credit

The goods Heidi's accessories are returning and therefore, the asset of inventory decreases. The credit to purchase returns reduces the value of the total purchases. That's why options C and D are incorrect.

2. Now, let's calculate the amount of the return that Heidi's accessories made, this way:

Return = Number of necklaces * Price of each necklace + Sales taxes

Replacing with the real values, we have:

Return = 5 * 10 + (5 * 10) * 0.06

Return = 50 + (50) * 0.06

Return = 50 + 3 = 53

<u>The correct answer is B. Accounts payable for US$ 53.oo</u>

the length of a rectangle is 2 inches less than 3 times it width . The perimeter of the rectangle is 124 inch. WHat is the lengt
vitfil [10]

Step-by-step explanation:

let w = width

length = 3w-2

perimeter = 2*length + 2*width

perimeter = 2(3w-2) + 2w

perimeter = 6w - 4 + 2w

perimeter = 8w - 4

perimeter = 124 inch

8w - 4 = 124inch

<em>+4 to each side</em>

8w = 128inch

<em>divide each side by 8</em>

w = 16

length = 3w-2

           = 3(16) - 2

length = 46 inch
