Fractions such as 1 ⁄ 3 are displayed as decimal approximations, for example rounded to 0.33333333. Also, some fractions (such as 1 ⁄ 7, which is 0.14285714285714; to 14 significant figures) can be difficult to recognize in decimal form; as a result, many scientific calculators are able to work in vulgar fractions or mixed numbers.
Volume was measured in ngogn (equal to 1000 cubic potrzebies), mass in blintz (equal to the mass of 1 ngogn of halva, which is "a form of pie [with] a specific gravity of 3.1416 and a specific heat of .31416"), and time in seven named units (decimal powers of the average earth rotation, equal to 1 "clarke").
It is expressed either as a decimal fraction or a percentage. A value of 0 indicates that the surface absorbs all solar radiation, and a value of 1 (or 100%) represents total reflectivity. Thermal emittance is the ability to emit absorbed heat. It is also expressed either as a decimal fraction between 0 and 1, or a percentage.
In primary education, fractions of grades are identified with a + or −, which signifies a quarter (converted to either 0.8 or 0.3 if only one decimal place is used). Thus, a grade of 6.75 (or 6.8) could be written as 7−, whereas a grade of 7+ would count for 7.25 or 7.3.
The median land area used by US nuclear power stations per 1 GW installed capacity is 1.3 square miles (3.4 km 2). [ 356 ] [ 357 ] To generate the same amount of electricity annually (taking into account capacity factors ) from solar PV would require about 60 square miles (160 km 2 ), and from a wind farm about 310 square miles (800 km 2 ).
The seats-to-votes ratio for a political party is the ratio between the fraction of seats and the fraction of votes for that party: a i = s i v i {\displaystyle a_{i}={\frac {s_{i}}{v_{i}}}} The Sainte-Laguë method approximates proportionality by optimizing the seats-to-votes ratio among all parties i {\displaystyle i} with the least squares ...
According to the 2009 NREAP [32] report biofuels were expected to provide the main source of RE in the transport sector rising from 1.3 petajoules (0.36 TWh) in 2010 to 10.9 petajoules (3.0 TWh) in 2020. Renewable electricity was expected to make up the minor share rising from 0.5 to 1.2 PJ (0.14 to 0.33 TWh) over the period for use in electric ...
