hodyreva [135]

Depends on the size of your desk generally, 2 sheets of paper can easily lay next to each other on a desk and papers are about 8 inches so about 16-20 inches wide of a desk and about 15 inches long
751/5= 150.2 inches too big for desk
751/10=75.1 inches too big for desk
751/500=1.502 feet or 18 inches a bit big for the desk but should be okay
751/5000=.1502 feet or 1.8 inches fits on desk but a bit small
I would go with either 1=5000 or 1=500 because those are the only 2 that would fit on your desk, probably the 1=5000 would be the best answer

Walmart buys shoes from a factory in China for $8.50. Walmart then marks up the price of the shoes by 65% to sell to their custo

Monica [59]

Answer

The shoes cost $14.03 at Walmart.

Explanation

The markup, the selling price and the cost price are all related through the relation

$\text{Markup percent = }\frac{(Selling\text{ Price) - (Cost Price)}}{(Cost\text{ Price)}}\times100$

For this question,

Markup percent = 65%

Selling Price = x = ?

Cost Price = $8.50

$\begin{gathered} \text{Markup percent = }\frac{(Selling\text{ Price) - (Cost Price)}}{(Cost\text{ Price)}}\times100 \\ 65=\frac{x-8.5}{8.5}\times100 \\ \text{Divide both sides by 100} \\ 0.65=\frac{x-8.5}{8.5} \\ \text{Cross multiply} \end{gathered}$

x - 8.5 = (0.65) (8.5)

x - 8.5 = 5.525

x = 8.5 + 5.525

x = $14.025

x = $14.03

Hope this Helps!!!

Jocelyn is a receptionist at a dentist office. She books 72 appointments each day. Six out of every 18 appointments are cancelle

bixtya [17]

Answer: 24

Step-by-step explanation: So if 6 out of ever 18 appointments are canceled, you need to find out how many “18 appointments” go into 72. So 72 divided by 18 is four. Now if 6 appointments get canceled four times, then it will be 6 times 4, which equals 24.
