72 is the sum between 60 and 12, the former being the second unitary perfect number before 6 (and the latter the smallest of only two sublime numbers). More specifically, twelve is also the number of divisors of 60, as the smallest number with this many divisors. [19] 72 is the number of distinct {7/2} magic heptagrams, all with a magic ...

The top grade, A, is given here for performance that exceeds the mean by more than 1.5 standard deviations, a B for performance between 0.5 and 1.5 standard deviations above the mean, and so on. [17] Regardless of the absolute performance of the students, the best score in the group receives a top grade and the worst score receives a failing grade.
The first fullerene to be discovered was buckminsterfullerene C 60, an allotrope of carbon with 60 atoms in each molecule, arranged in a truncated icosahedron. This ball is known as a buckyball, and looks like a soccer ball. The atomic number of neodymium is 60, and cobalt-60 (60 Co) is a radioactive isotope of cobalt.
The interest rate shouldn’t be expressed as a decimal out of 1, such as 0.07 for 7 percent. It should just be the number 7. So, for example, 72/7 is 10.3, or 10.3 years.
For example, 72 = 2 3 × 3 2, all the prime factors are repeated, so 72 is a powerful number. 42 = 2 × 3 × 7, none of the prime factors are repeated, so 42 is squarefree. Euler diagram of numbers under 100:
The Ages of Three Children puzzle (sometimes referred to as the Census-Taker Problem [1]) is a logical puzzle in number theory which on first inspection seems to have insufficient information to solve.
A decrease of 60% means the final amount is 40% of the original (100% – 60% = 40%). A decrease of 100% means the final amount is zero (100% – 100% = 0%). In general, a change of x percent in a quantity results in a final amount that is 100 + x percent of the original amount (equivalently, (1 + 0.01 x ) times the original amount).
