Answer:

[tex]z= \frac{1}{3}[/tex]

Explanation:

Given

[tex]\frac{z}{7} = \frac{1}{21}[/tex]

Required

Solve

[tex]\frac{z}{7} = \frac{1}{21}[/tex]

Multiply both sides by 7

[tex]7 * \frac{z}{7} = \frac{1}{21} * 7[/tex]

[tex]z= \frac{1}{21} * 7[/tex]

Rewrite as:

[tex]z= \frac{1 * 7}{21}[/tex]

[tex]z= \frac{7}{21}[/tex]

Simplify fraction

[tex]z= \frac{1}{3}[/tex]

Two parter:

A.) What is wrong with the program segment below? The program does not contain syntax errors.

B.) Fix the programming error(s)

num = 1;

while (num < 9)
{
cout << num;
num = num - 1;
}

Answers

Answer:

the variable num is not declared so the compiler doesn't define it.

add int before num:

int num = 1;

while (num < 9)

{

cout << num;

num = num - 1;

}

now the code will run but it won't stop as it will never break the condition (num < 9).

in ICT what is the difference between Save and Save As

Answers

Choosing "Save" simply saves your work by updating the last saved version of the file to match the current version you see on your screen.

Choosing "Save As..." brings up a prompt to save your work as a file with a different name. For example, you might choose to save a document called "Paper - rev. 3" as "Paper - rev. 4". This way, you can save you file at different stages and keep multiple versions on your hard drive.

Choosing "Save" and then "Save As..." is also a good way to make a backup of your file. Just be sure to rename the file something new when you choose "Save As..." or you will overwrite the current saved version, just like choosing the "Save" command would do.

Answer:

Save updates the files that are already created.

Save as creates a new file or store the existing file in a new location.
