What would be the total width of the div in the code below?

Artyom0805 [142]

Answer:

The answer to this question is given below in the explanation section.

Explanation:

The correct answer to this question is d- 346px.

The complete code of this example is given below:

<div>

style="margin:20px; border:solid 3px #888888;">

</div>

while the image width is 300px.

It is noted that the image width is 300px and the margin is 20 px.

Margin:20px means that image margin from four side is 20 px each.

So the width of dive from both side increase to 40 px and the image has 300 px, then total width becomes 340px. Now the border also has 3px of four sides of the image, then the width of the border becomes 6px.

so the total width of the div tag is 346 px.

In short, we can calculate the width of tag as below:

total width of div= width of image+ width of margin+ width of border

total width of dive= 300px+40px+6px

total width of div=346px.

trapecia [35]

Answer:

<u> A. It uses binary numbers in its algorithm</u>

Explanation:

A Binary search is a type of algorithm designed to look through <em>only </em>a sorted array of data for a particular item.

It is<em> more efficient (faster) </em>than sequential search since the algorithm doesn't have to look up the entire array of data, but simply repeatedly divide in half the section of the array that could contain the searched item.

irina1246 [14]

Answer:

Project Identification

Provide the identifying information associated with the project, including the applicable project control code, system acronym, and system title.

System Proponent

Provide the name of the System Proponent.

History of the System

Briefly describe the system’s history and predecessor, if any. State the mission needs and information requirements, including how the system is expected to help users.

Functional System Description and Data Usage

Briefly describe what the system does functionally and how the data are used by the system.

Explanation:

Overview

The Post-Implementation Review is used to evaluate the effectiveness of the system development after the system has been in production for a period of time (normally 6 months). The objectives are to determine if the system does what it is designed to do: Does it support the user as required in an effective and efficient manner? The review should assess how successful the system is in terms of functionality, performance, and cost versus benefits, as well as assess the effectiveness of the life-cycle development activities that produced the system. The review results can be used to strengthen the system as well as system development procedures.

The review is scheduled to follow the release of a system or system revision by an appropriate amount of time to allow determination of the effectiveness of the system. A representative from the functional development group or other member of the major user organization participates in the review. The System Proponent ensures that all documentation and all personnel needed to participate in the review are accessible.

The reviewer and an assigned team collect the information needed for the Post-Implementation Review by interviewing end users and their managers, system administrators, and computer operations personnel. The report is then prepared and provided to the user organization that requested it and the information systems organization, which may jointly use the findings to initiate other actions.

The Post-Implementation Review is a free-form report, and not all sections are relevant or necessary to the final product. A description of the Post-Implementation Review Report is attached.
