[6] 72 has an Euler totient of 24. [7] It is a highly totient number, as there are 17 solutions to the equation φ(x) = 72, more than any integer under 72. [8] It is equal to the sum of its preceding smaller highly totient numbers 24 and 48, and contains the first six highly totient numbers 1, 2, 4, 8, 12 and 24 as a subset of its proper divisors.
In finance, the rule of 72, the rule of 70 [1] and the rule of 69.3 are methods for estimating an investment's doubling time. The rule number (e.g., 72) is divided by the interest percentage per period (usually years) to obtain the approximate number of periods required for doubling.
A mathematical constant is a key number whose value is fixed by an unambiguous definition, often referred to by a symbol (e.g., an alphabet letter), or by mathematicians' names to facilitate using it across multiple mathematical problems. [1]
The natural log of 2 is 0.693147, so when you solve for t using those natural logarithms, you get t = 0.693147/r.. The actual results aren’t round numbers and are closer to 69.3, but 72 easily ...
Works with 15 mm miniatures where a 6 foot man would equal 15.24 mm 1:110: 2.771 mm Used for some model ships, aircraft and diecast cars. 1:108: 2.822 mm An historic size for ships, also used for rockets and spacecraft. 15 mm figure scale for wargaming is considered interchangeable with this scale.

9 is the fourth composite number, and the first odd composite number. 9 is also a refactorable number. [ 2 ] Casting out nines is a quick way of testing the calculations of sums, differences, products, and quotients of integers in decimal , a method known as long ago as the 12th century.
Microsoft Word, for instance, suggests every even size between 8 and 28 points and, additionally, 9, 11, 36, 48 and 72 points, i.e. the larger sizes equal 3, 4 and 6 picas. While most software nowadays defaults to DTP points, many allow specifying font size in other units of measure (e.g., inches, millimeters, pixels), especially code-based ...
