Given that Jamie worked 50 hours (Hours = 50) last week and earns $10.00 an hour (Rate = 10), how much did Jamie earn last week,
quester [9]

Answer:

<em>Jamie earned (Total pay)  $500.</em>

<em></em>

Explanation:

We are given the following code:

<em>If (Rate >=10) OR (Hours <=40) Then </em>

<em>    TotalPay = Hours * Rate </em>

<em>Else </em>

<em>    TotalPay = (Hours * Rate)+(Hours–40)*Rate*1.5 </em>

<em>End If</em>

<em />

Let us understand the code line by line:

The first line contains an if statement with 2 conditions:

i.e. 1st condition:

The rate is greater than or equal to 10

2nd condition:

Number of hours are lesser than or equal to 40.

There is OR between the two condition i.e. the statement next to if() statement will get executed if any one of them becomes true and else part will not be executed.

The next statement is:

TotalPay = Hours * Rate

It calculates the pay if any of the two conditions written earlier becomes true.

Next statement is else statement:

It will get executed given that the above if() statement becomes false.

Now, we are given that Jamie worked 50 hours last week and earns $10.00 an hour:

i.e.

Hours = 50

Rate = 10

Now, let get to the code execution.

The first condition is true i.e. Rate >= 10 (because Rate is 10 here)

So, the following statement will be used to calculate the Total pay:

TotalPay = Hours * Rate

and else part will not be executed.

TotalPay = 50 * 10  =<em> $500  </em>

<em></em>

<em>Jamie earned (Total pay)  $500.</em>

What name is used to denote a common field that exists between two tables, but is also the primary key for one of the tables??"
Diano4ka-milaya [45]

Answer:

b. foreign key

Explanation:

In the database world, a foreign key is a field on one table and a primary key for another table. The purpose of a foreign key is to provide linkages between two or more tables. Given two tables A and B, and making A the point of reference, a primary key is a field that is unique in A while a foreign key is unique in B.

On another hand, a composite primary key is a combination of two or more fields/columns on database table that can be used to uniquely identify each row in the table.

In the database lingua, what we have is a unique key not a distinct key, though the two words are similar in meaning.

A duplicate key is used when an information may be repeatedly entered on a table.

So the correct option is a foreign key.
