Concatenate jquery variable with string

I am caching a selector into a jquery variable, like so: 

var elem = $('.wrapper');

I want to perform different queries on the variable according to certain properties. gt(0), :visible, :hidden etc.

By my reckoning, it should look like this: 

var elemHidden = $(elem+':hidden');

Of course this is not working. I am assuming it is simple, or something quite close to the code I have.

Here is a jsfiddle: http://jsfiddle.net/lharby/5m7nf97r/

Here is some HTML: 

<div class="wrapper">Wrapper 1</div>
<div class="wrapper">Wrapper 2</div>
etc..

You should use the $.is() method:

elem.is(':hidden');
elem.is(':visible');
elem.is(':checked');

And for other specific methods as $.gt()

elem.gt(0); or $(elem).gt(0)

You can not concatenate a jQuery object and a string. You want to use filter to reduce the set.

var elemHidden = elem.filter(':hidden');
