In a math problem, it means the same as in real life. There are limits to what you can do, or range of values a variable may take on.
You cannot work more hours in a week than there are hours in a week. You cannot measure lengths less than 0, or time before the present. You cannot sensibly divide by zero. In general, you cannot use more resources than you have, or make use of them before they existed.
There are practical limits to size, speed, size of numbers,* and there are limits imposed by the laws of physics we recognize. (Objects can only be so big or so small or so many in the known universe, or within the confines of habitable portions of the Earth.)
___
* The ratio of the size of the known universe to the size of the smallest describable object is less than 10^300. You can write numbers larger or smaller (than the inverse of this), but they have no practical meaning in our universe.

Answer:
sin(-255°) = √2 + √6/4
Step-by-step explanation:
We need to find sin -255°
We know that sin(-a) = - sin(a)
so, sin(-255°) = - sin 255°
We know that 180° + 75° = 255°
Now we can write sin(255°) = sin(180° + 75°)
We can use the identity:
sin(x+y) = sin(x) cos(y)+cos(x)sin(y)
x = 180° , y = 75°
Solving,
sin(x+y) = sin(x) cos(y)+cos(x)sin(y)
sin(180° + 75°) = sin(180°) cos(75°)+cos(180°)sin( 75°)
sin(180°) = 0
cos(75°) = √6 -√2/4
cos(180°) = -1
sin( 75°) = √2 + √6/4
Putting values,
sin(180° + 75°) = 0 (√6 -√2/4) + (-1)(√2 + √6/4)
sin(180° + 75°) = -(√2 + √6/4)
We know that sin(-255°) = -sin(255°)
Putting value of sin(255°)
sin(-255°) = -(-(√2 + √6/4))
sin(-255°) = √2 + √6/4
Answer:
They would get 192.5
Step-by-step explanation:
First we need to find how much it cost per 1 so you will need to dovide 110 by 20 which equal 5.5
Then you will multiply 5.5*35 and get 192.5
