750 in everyday use
Seven hundred fifty is the number of millilitres in a standard wine bottle, a size fixed by European regulation in the 1970s and adopted by the United States in 1979 when it replaced the fifth of a gallon, which held 757 mL. Spirits followed the same bottle. The number is three quarters of a thousand, so a 750 W appliance draws three quarters of a kilowatt and 750 g is three quarters of a kilogram. Motorcycles in the 750cc class were the superbikes of the 1970s.
Arithmetically 750 is 2 × 3 × 5³, with sixteen divisors, and it is 6 × 125, six copies of five cubed. It is also 3 × 250, and it is not a sum of two squares, since 3 divides it exactly once. It is 1011101110 in binary and 2EE in hexadecimal. Its digit sum is 12, and it lies between the primes 743 and 751, the second of which is 157 reversed.
