How much weight could a leather belt hold before it breaks?
Best answer: Depending on the leather quality, the strength of cowhide leather varies from around 8 to 25N per square millimetre of cross section.
Stiffer leathers as used for belts are in the stronger range, so call it 20N per mm^2 at a rough guess.
(Soft leathers such as used for gloves & jackets etc. are at the lower end of the strength range).
If the belt is 25mm wide and 4m thick, that's 100mm^2 section so very roughly 2000N or 200Kg breaking strain.
That is for a single piece. As a loop, so doubled (and if the buckle can take the strain), it should hold roughly double that.
The figures are also based on the belt being real leather and not a plastic fake or composite "bonded leather" which is again largely plastic.

((4/3)x^36x^2+16x+66)/(x+3). How do you divide this? The fraction is throwing me off. Should i multiply every term by 3 to remove it?
Best answer: The leading term of the quotient will be (4/3)x^2.
The partial product is (4/3)x^3  4x^2.
The remainder is 2x^2 + 16x + 66.
The 2nd term of the quotient will be 2x.
The partial product is 2x^2  6x.
The remainder is 22x + 66.
The third term of the quotient will be 22.
The partial product is 22x + 66.
There is no remainder.
Final answer: the quotient is (4/3)x^2  2x + 22.
