Find the cost of 2m 20cm at 25p per metre
Answers
Answer: 55 meters.
Explanation:
First convert the 20 cm to meters so the entire number is in meters.
1 meter = 100 cm
20 in cm is:
= 20/100
= 0.2 meters.
2.2 meters.
One meter costs 25p so 2.2 meters will cost:
= 2.2 * 25
= 55 meters
Describe some common types of charts.
Answers
Pie chart.
Line chart.
Answer:
The four most common are probably line graphs, bar graphs and histograms, pie charts, and Cartesian graphs. They are generally used for, and are best for, quite different things.
Explanation:
Line chart- A graph with points connected by lines to show how something changes in value: • as time goes by, • or as something else changes.
Example: how you are improving at a quiz each day.
Bar chart- A graph drawn using rectangular bars to show how large each value is. The bars can be horizontal or vertical. It is a really good way to show relative sizes. We can use bar graphs to show the relative sizes of many things, such as what type of car people have, how many customers a shop has on different days and so on.
Histogram- a graphical display of data using bars of different heights. It is similar to a Bar Chart, but a histogram groups numbers into ranges . The height of each bar shows how many fall into each range.
Pie chart- a special chart that uses "pie slices" to show relative sizes of data. It is a really good way to show relative sizes.
Cartesian chart- This is a type of chart that uses coordinates to pinpoint where something is on a map or graph. Using Cartesian Coordinates we mark a point on a graph by how far along and how far up it is.

1. Visual design and font/background are both essential and considered vital for the success of a web. If you are the developer, which of the two will you be focused on?
Answers
Answer:
As a developer, I'd be focused on the two starting with the front end.
Explanation:
A front-end developer simply is a user-end or client-side developer. A front-end person in web design is responsible for how a website looks and feels like, essentially, the websites' users first impression.
This is a huge task and can be very daunting even for the best developers. Whilst the back-end or the engine of a website is critical and indispensable, it is important for a developer to master the principles of front-end development first as that gives him a better perspective as to how they can better create and configure a matching or suitable back end.
Most if not all are designed to achieve a particular purpose e.g.
Increase salescommunicate informationtrainingelicit information etcThe ease with which the user is able to interact with the website will determine the extent to which the purpose of the website is achieved.
Some of the qualities of a great user interface the front end developer must keep in mind are:
Clarity Conciseness Familiarity EfficiencyConsistency AttractivenessBack-end has to do with the part of the website called the server.
In addition to the server, there are two other critical components of the back-end of the website:
Application and Database.Together, these three contribute to ensuring that you have a functional website. The server, application and database, all control what happens on the front end and results in what the user will see via the browser.
There are many high-functioning websites today that have very poor interfaces. A poor interface is a guarantee that people will spend less time on the website.
Conclusively, both ends are indispensable, as with most things, however, one should seek to understand how the user thinks and feels in relation to how they like to use a website before doing into the back-end to make that possible.
Cheers

Answers
Answer:
The program only runs 5 five since the for loop statement is limited to loop only five times.
Explanation:
In programming, a for-loop statement is used to repeat a collection of events a definite number of times. The number of loops is specified and compared with a variable to execute a block of code.
The for-loop statement in the code above declares and initializes a variable "i" to zero, runs the block of code, and increments by one if it is less than 5.
To make it run eight times, the value five should be changed to 8 instead.
Answer: you have to change the 5 to 8 since its telling you to do it 8 times
Explanation: for(var i = 0; i < 5; i++) should be for(var i = 0; i < 8; i++)

It allows the designer to focus on main logic without being distracted by programming languages syntax.
* Since it is language independent, it can be translated to any computer language code.
* It allows designer to express logic in plain natural language.
* It is easier to write actual code using pseudocode.
* Unlike algorithms, pseudocodes are concise so pseudocodes are more readable and easier to modify.
