Answer 3

It is based on international standards put forth by the ISO (International Organization for Standardizations):

The ISO paper size concept
In the ISO paper size system, the height-to-width ratio of all pages is the square root of two (1.4142 : 1). In other words, the width and the height of a page relate to each other like the side and the diagonal of a square. This aspect ratio is especially convenient for a paper size. If you put two such pages next to each other, or equivalently cut one parallel to its shorter side into two equal pieces, then the resulting page will have again the same width/height ratio.

The ISO paper sizes are based on the metric system. The square-root-of-two ratio does not permit both the height and width of the pages to be nicely rounded metric lengths. Therefore, the area of the pages has been defined to have round metric values. As paper is usually specified in g/m², this simplifies calculation of the mass of a document if the format and number of pages are known.

ISO 216 defines the A series of paper sizes based on these simple principles:

The height divided by the width of all formats is the square root of two (1.4142).
Format A0 has an area of one square meter.
Format A1 is A0 cut into two equal pieces. In other words, the height of A1 is the width of A0 and the width of A1 is half the height of A0.
All smaller A series formats are defined in the same way. If you cut format An parallel to its shorter side into two equal pieces of paper, these will have format A(n+1).
The standardized height and width of the paper formats is a rounded number of millimeters.

Answer 4

long island is standard as "long island" because of the fact before a properly-standard human beings hero (Johnny Appleseed) planted a single seed interior the path of the city. Then, in an unusual warp in area-time, a boy named Jack planted a seed he believed to be magical interior an identical spot. In what remains seen a marveling organic and organic progression, the two seeds fused at the same time on a molecular point. After an stunning rain, the seed hybrid grew into an apple 300ft tall and approximatively 330ft huge. The strangest element being the absence of a tree. it form of feels the apple grow to be thoroughly established, different than it grew as we talk from the floor with its own roots like a beanstalk of a few type. for some destiny years, human beings could flow to the city and look up on the impossible fruit and think of "it particularly is a huge apple". After a on an identical time as human beings began relating the city itself as "long island". yet then, 1943 Oct 11th, some thing unusual surpassed off. because of the fact the city laid to kick back, the night as quickly as lower back upon them, there grow to be a stunning flash of pink gentle. The flash lasted for almost 4-5 seconds. no person is definite what brought about the flash, yet as quickly because it grow to be over the apple had basically disappeared. no longer purely had it vanished, the floor it had grown from had closed as though it have been on no account there. some say the apple had grown so super it created some variety of fruity supernova and collapsed in on itself in a black hollow. some say the extraterrestrial beings to blame for the dying of the dinosaurs got here lower back and destroyed the apple as properly. We could on no account comprehend precisely what surpassed off that night, yet one element is for particular. That grow to be a huge-*** apple.
