Which decimal value (base 10) is equal to the binary number 1012?

GaryK [48]

Answer:

The decimal value of 101₂² base 2 = 25 base 10

Explanation:

The number 101₂² in decimal value is found as follows;

101₂ × 101₂ = 101₂ + 0₂ + 10100₂

We note that in 101 + 10100 the resultant 2 in the hundred position will have to be converted to a zero while carrying over 1 to the thousand position to give;

101₂ + 0₂ + 10100₂ = 11001₂

Therefore;

101₂² = 11001₂

We now convert the result of the square of the base 2 number, 101², which is 11001₂ to base 10 as follows;

Therefore converting 11001₂ to base 10 gives;

11001₂= 1 × 2⁴ + 1 × 2³ + 0 × 2² + 0 × 2 ¹ + 1 × 2⁰

Which gives;

16 + 8 + 0 + 0 + 1 = 25₁₀.

Andy wants to add a script on his website that will automatically update the current date when the script loads in the browser.

FrozenT [24]

The script that Andy would want to use is Javascript, here is the source code: document.getElementById("para1").innerHTML = formatAMPM();
function formatAMPM() {var d = new Date(), minutes = d.getMinutes().toString().length == 1 ? '0'+d.getMinutes() : d.getMinutes(), hours = d.getHours().toString().length == 1 ? '0'+d.getHours() : d.getHours(), ampm = d.getHours() >= 12 ? 'pm' : 'am', months = ['Jan','Feb','Mar','Apr','May','Jun','Jul','Aug','Sep','Oct','Nov','Dec'], days = ['Sun','Mon','Tue','Wed','Thu','Fri','Sat'];return days[d.getDay()]+' '+months[d.getMonth()]+' '+d.getDate()+' '+d.getFullYear()+' '+hours+':'+minutes+ampm;<span>}

The HTML code needed to call this Javascript on his website is this: </span><span><div id="para1"></div>
</span>
You could call the Javascript up using PHP.

Hope this helps! Good luck! :)

// Single line comments (This starts with two forward slashes

/* Multiple Line

comment

Style*/

The third is the javadoc that gives a description of a function. I looks like the multiple line but is has two asterics

/** This is javadoc

comment

style*/

why might you want to use the send to compressed (zipped) folder command before sending four pictures to a friend via email

IceJOKER [234]

It's easier to send the files that way because you don't have to attach them individually, and then your friend won't have to download them individually - they can just download the zip package and have all four right at their disposal.
