Answer:

d+n=35\\0.10d+0.05n=3.30

Explanation:

Multiple Choices aren't given, so I will just solve this.

Josiah had "d" dimes and "n" nickels.

There are a total of 35 coins, nickels and dimes.

The value of "d" dimes and "n" nickels is $3.30

Note: Value of nickels is 0.05 and dimes is 0.10 (in dollars)

The system of equations (2) we can use to solve this will be:

1) an equation involving total number of coins

2) an equation stating the value of each coin and total value

Equation 1:

d + n = 35

Equation 2:

0.10d+0.05n=3.30

These are the 2 equations that can be solved simulataneously to find the number of nickels and dimes.

iVinArrow [24]

Answer:

A printer is a device that accepts text and graphic output from a computer and transfers the information to paper, usually to standard size sheets of paper. Printers vary in size, sophistication, speed, and cost. In general, more expensive printers are used for higher-resolution color printing.

Printers today have many features that include improved quality, photo printing capabilities, digital camera connectivity, built-in flash memory card readers, wireless connectivity, and faster speed.  

The Six important printer qualities are:

  1. Color: It is important for users who need to print pages for presentations or maps, photos and other pages where color is part of the information. Color printers can also be set to print only in black-and-white. Color printers are more expensive to operate since they use two ink cartridges (one color and one black ink, toner) that need to be replaced after a certain number of pages. Users who don't have a specific need for color and who print a lot of pages will find a black-and-white printer cheaper to operate.  
  2. Resolution: Printer resolution (the sharpness of text and images on paper) is usually measured in dots per inch (dpi). Most inexpensive printers provide sufficient resolution for most purposes at 600 dpi.
  3. Speed: If you do much printing, the speed of the printer becomes important. Inexpensive printers print only about 3 to 6 sheets per minute. Color printing is slower. More expensive printers are much faster.
  4. Memory: Most printers come with a small amount of memory (for example, one megabyte) that can be expanded by the user. Having more than the minimum amount of memory is helpful and faster when printing out pages with large images or tables with lines around them (which the printer treats as a large image).
  5. Wireless connectivity : Specialized printer nowadays have wireless connectivity which allows user to communicate with the machine without physical operation. Like one can just give command to the printer to print their projects using their mobile phone while sitting on the couch. This feature might add extra bucks to the bill but its worth it.
  6. Printer languages The commands from the computer to the printer to tell the printer how to format the document being printed. These commands manage font size, graphics, compression of data sent to the printer, color, etc. The two most popular printer languages are Postscript and Printer Control Language.

Conclusively the best printer will be the one which will provide pleasant color contrast, good resolution, enough memory, wireless connectivity and have better language settings.

Many restaurants offer daily specials, appetizers, entrees, and desserts not listed on their standard menu. These daily specials
stiv31 [10]

Answer:

B) satisfying the changing needs of current and new customers.

Explanation:

When a restaurant wants to introduce a new dish, it's best to test the market response to the dish before listing it on the standard menu. A type of test would be offering the dish only in special occasions, when sales are higher, and more potential customers visit the restaurant.

Another way is to simply offer the dish in a normal weekday, and see how people respond to it under regular conditions.

Marianna [84]

Answer:

$508.63

Explanation:

For this question, we use the Present value formula that is reflected in the attached spreadsheet. Kindly find it below:

Provided that

Given that,  

Future value = $1,000

Rate of interest = 14%

NPER = 15 years

PMT = $1,000 × 6% = $60

The formula is shown below:

= -PV(Rate;NPER;PMT;FV;type)

So, after solving this, the present value is $508.63
