The legend is inscribed with "KRUGERRAND" and the gold weight. The Krugerrand ( / ˈkruːɡərænd /; [ 1] Afrikaans: [ˈkry.ərˌrant]) is a South African coin, first minted on 3 July 1967 to help market South African gold and produced by Rand Refinery and the South African Mint. [ 2][ 3] The name is a compound of Paul Kruger, the former ...
The 1978 series began with denominations of 2, 5, 10, and 20 rand, with a 50 rand introduced in 1984. This series had only one language variant for each denomination of note. Afrikaans was the first language on the 2, 10, and 50 rand, while English was the first on the 5 and 20 rand. A coin replaced the 1 rand note.
The misdirection in this riddle is in the second half of the description, where unrelated amounts are added together and the person to whom the riddle is posed assumes those amounts should add up to 30, and is then surprised when they do not — there is, in fact, no reason why the (10 − 1) × 3 + 2 = 29 sum should add up to 30.
By the fourth quarter of 2010, the household net worth had recovered by a growth of 1.3 percent to a total of $56.8 trillion. An additional growth of 15.7 percent is needed just to bring the value to where it was before the recession started in December 2007. [22] In 2014 a record breaking net worth of $80.7 trillion was achieved. [64]
Contribution margin (CM), or dollar contribution per unit, is the selling price per unit minus the variable cost per unit. "Contribution" represents the portion of sales revenue that is not consumed by variable costs and so contributes to the coverage of fixed costs. This concept is one of the key building blocks of break-even analysis.
Rounding or rounding off means replacing a number with an approximate value that has a shorter, simpler, or more explicit representation. For example, replacing $ 23.4476 with $ 23.45, the fraction 312/937 with 1/3, or the expression √2 with 1.414 .
In mathematics, a rate is the quotient of two quantities in different units of measurement, often represented as a fraction. [1] If the divisor (or fraction denominator) in the rate is equal to one expressed as a single unit, and if it is assumed that this quantity can be changed systematically (i.e., is an independent variable), then the dividend (the fraction numerator) of the rate expresses ...
An increase of $0.15 on a price of $2.50 is an increase by a fraction of 0.15 / 2.50 = 0.06. Expressed as a percentage, this is a 6% increase. While many percentage values are between 0 and 100, there is no mathematical restriction and percentages may take on other values. [4]
