An equivalent (symbol: officially equiv; [1] unofficially but often Eq [2]) is the amount of a substance that reacts with (or is equivalent to) an arbitrary amount (typically one mole) of another substance in a given chemical reaction. It is an archaic quantity that was used in chemistry and the biological sciences (see Equivalent weight § In ...
A-plusses, if given, are usually assigned a value of 4.0 (equivalent to an A) due to the common assumption that a 4.00 is the best possible grade-point average, although 4.33 is awarded at some institutions. In some places, .25 or .3 instead of .33 is added for a plus grade and subtracted for a minus grade.
The WASL assessment consisted of examinations over four subjects (reading, mathematics, science, and writing) with four different types of questions (multiple-choice, short-answer, essay, and problem solving). It was given to students from third through eighth grades and tenth grade.
Roughly, the Bulgarian grade system can be equated to the American one like the following: 6=A, 5=B, 4=C, 3=D, and 2=F. Also, in accordance with the Australian system, 6=HD, 5=D, 4=Cr, 3=P, and 2=F. The most common formula used in Bulgarian schools is currently Grade=(6* number of correct answers)/ total number of questions.
98.6 °F (37.0 °C) is not the normal or average temperature of the human body. That figure comes from an 1860 study, [297] but modern research shows that the average internal temperature is 36.4 °C (97.5 °F), with small fluctuations. [298] [299] [300] The cells in the human body are not outnumbered 10 to 1 by microorganisms. The 10 to 1 ...
If the initial amount p leads to a percent change x, and the second percent change is y, then the final amount is p (1 + 0.01 x)(1 + 0.01 y). To change the above example, after an increase of x = 10 percent and decrease of y = −5 percent, the final amount, $209, is 4.5% more than the initial amount of $200.
