If x has a value of 7 and y has a value of 20, what is displayed as a result of executing the code segment

Llana [10]

6.65 is displayed as the output of the block of code

In python programming, * denotes multiplication. To get the output, we will substitute the value of x and y given into the result to have;

result = x * y - x / (y)

result = 7 * 20 - 7 / (20)

result = 140 - 7 / (20)

result = 133/20

result = 6.65

This shows that 6.65 is displayed as the output of the block of code

The question is incomplete;

Let the code segment be

>>> x = 7

>>> y = 20

>>> result = x * y - x / (y)

>>> result

output:__?

An identifier that allows multiple elements in an HTML document to be styled in the same way

oksian1 [2.3K]

Answer:

CSS , (Possibly Divs)

Explanation:

I have picked CSS, and possibly Div's as my main explanation and answer here is why.

CSS - Cascading Style Sheets, this allows you to edit multiple elements in a HTML document, such as the color or any CSS attribute.

If you would like to learn more about CSS, and the multiple options that CSS provides such as Internal Styles, External Styles, lastly In-line styles. I highly recommend the resource "W3Schools".

DIV's - Divs are basically like a container, where you can input styles into this container that can effect those elements such as if I want the background-color, of the div it would effect all the elements inside that div. However, I said this could be a possibility since it isn't CSS where it is styled however you can group these elements to one div. You can also edit the CSS of the Div to effect it.

Let's assume that you wrote a query that has the following four clauses: SELECT, FROM, WHERE, ORDER BY. The order in which the f

morpeh [17]

Answer:

"From, where, select ,order by" is the correct answer for the above question.

Explanation:

When a user creates a query in comparison of "SELECT, FROM, WHERE ORDER BY", then the query will execute in the "From, where, select, order by" order.
Firstly form clause will execute because it holds the name of the table which defined the address of the data which needs to fetch.
Then the where clause will execute which is used to filter the data. It states the correct location of the data in the table.
Then the select clause is executed because it works to fetch the data and gives the output to the user.
Then the order by clause is executed because it states the data in ascending or descending order.
