Since we are adding 1 to the tens digit and subtracting one from the units digit, the sum of the digits should remain the same. For example, 9 + 2 = 11 with 1 + 1 = 2. When adding 9 to itself, we would thus expect the sum of the digits to be 9 as follows: 9 + 9 = 18, (1 + 8 = 9) and 9 + 9 + 9 = 27, (2 + 7 = 9).
The purity of a gas is generally expressed as a grade prefixed with the letter N (rather than postfixed), indicating the "number of nines" in the percentage or decimal fraction. For example, a N2.0 gas is 99% (two nines) pure and 1% impurities by volume; a N6.0 gas is 99.9999% (six nines) pure, with 1 part per million (1 ppm or 1 vpm, volume ...
Example of a set of 53 edged-notched cards used by Gordon Bell to gather information for a book (Computer History Museum) Example of a blank pre-printed edge-notched card designed to store bird population research data (Smithsonian) Example of a commercially-produced notched card reference database, the Isotope Datadex (1961-1970)
Consistent with the example illustrated above, a grading curve allows academic institutions to ensure the distribution of students across certain grade point average (GPA) thresholds. As many professors establish the curve to target a course average of a C, [ clarification needed ] the corresponding grade point average equivalent would be a 2.0 ...
For example, poikilocytosis can be caused by a vitamin deficiency (e.g. vitamin B 12, folic acid), in which case the treatment is to replenish the deficient vitamin. It can be caused by a digestive disease, such as celiac disease , in which case the solution may lie in treating the underlying celiac disease so that nutrients can be properly ...
There are several types of test used to measure fracture toughness of materials, which generally utilise a notched specimen in one of various configurations. A widely utilized standardized test method is the Charpy impact test whereby a sample with a V-notch or a U-notch is subjected to impact from behind the notch. Also widely used are crack ...
Examples of this are the English verbs lay and pay. In terms of pronunciation, these make their past forms in the regular way, by adding the /d/ sound. However their spelling deviates from the regular pattern: they are not spelt (spelled) "layed" and "payed" (although the latter form is used in some e.g. nautical contexts as "the sailor payed ...
Excluded are the numerous spellings which fail to make the pronunciation obvious without actually being at odds with convention: for example, the pronunciation / s k ə ˈ n ɛ k t ə d i / [1] [2] of Schenectady is not immediately obvious, but neither is it counterintuitive.
