I think it's 28 -- there are four sixteenth notes in one quarter note times seven beats in the measure. However, I've never heard of a time signature with seven beats, so it's probably not very relevant. Also, this answer assumes each beat is a quarter note (not, say, a dotted quarter or an eight).

8 a dotted sixteenth is equal to rest/note is equal to 3/8 of a beat in 4/4 time signature. a dotted half is equal to 3 beats or 24/8 of a beat. so 24/3=8

If it is 4/4 time, then it gets 1/4 of that quarter note. So meaning there would be 16 sixteenth notes in a measure if you filled the bar with sixteenth notes.
The clue is in the name of the note. The sixteenth (or semiquaver) is one-sixteenth of a whole note (or semibreve). Look at the time signature of your piece of music: a semiquaver rest will occupy exactly the same number of beats as a semiquaver note. For example, if your piece is in 4/4 time, it will occupy a quarter of a beat.

it really depends on the time signature, but in 4/4 a whole rest gets four beats of rests

A sixteenth note receives 1/4 of a beat. It is referred to as a "sixteenth note" because it takes sixteen of them to create 4 beats. Most songs contain 4 beat measures known as "common time."

In 4 4 time, it would get 3/4 of a beat.
Four - just like the number of sixteenth notes in a quarter note. If you think about it like math, 4/16 = 1/4
In 3/4 time (whether you are playing a piano or a kazoo), there are 3 beats to the measure and a quarter note gets one beat. There are four sixteenth notes to a quarter note so the sixteenth note gets 1/4 of a beat or, another way to look at it is it takes 4 sixteenths to make a beat.
There are many kinds of notes and rests, each with a different amount of time. A quarter note generally denotes one beat, a half note two beats, a whole note four beats. An eighth note is half a beat, a sixteenth note is one-fourth of a beat. A dot at the end of a note adds one beat to the note (i.e. a dotted half note is three beats). This whole explanation is assuming you are in 2/4, 3/4, 4/4, 5/4, 6/4, etc. time.
