What are some bird names that are 4-letters long?
In the August 2017 Clements Checklist, there are ten bird species with four-letter English names:Dodo, a famously extinct flightless bird of the pigeon and dove family, endemic to Mauritius (that is, found there and nowhere else).Huia, an extinct wattlebird from New Zealand.Iiwi (ʻiʻiwi), a bright red Hawaiian bird in the finch family, with a long curved bill.Kagu, a bird in its own family, endemic to New Caledonia.Omao (ʻōmaʻo), a robin-like thrush endemic to the island of Hawaii.Rook, a Eurasian corvid (member of the crow family).Ruff, a Eurasian shorebird with very unusual breeding plumage.Smew, a duck of northern Eurasia, related to the mergansers and goldeneyes.Sora, a rail from North America.Weka, a flightless rail from New Zealand.Dodo display at Oxford University Museum of Natural History; photo by Wikimedia Commons user BazzaDaRambler.Huia illustration by J.

Which sentence is correct, "The party starts at eight o'clock." or "The party is starting at eight o'clock."?
Both sentences are grammatically incorrect, although they are used in day-to-day speech. The party is scheduled to happen in the future, whereby it will be started at at 8pm. Logically, the best way to state it:The party will start at eight o'clock.The party will begin at eight o'clock.The party will be started at eight o'clock.It is as simple as that. People of older generations were so much better at the language. The way the language is tortured, is dumbfounding!
If 12 men are working 8 hours a day and they complete the job in 5 days then how many men working for 10 hours a day complete the same job?
We will use Chain Rule to solve this question.According to Chain Rule, the work efficiency remains constant.[math]\dfrac {W}{WF \times T} [/math]= ConstantHere W = Work Done, WF = Workforce, T = Time.Let the number of men needed be 'x'.Applying Chain Rule,[math]\dfrac {W}{12 \times 8 \times 5} = \dfrac {W}{x \times 10 \times 5} [/math]Or, [math]x = 9.6[/math] MenSo, you need 10 men approximately.

In C language, the integer takes 2 bytes for a 32-bit compiler and 4 bytes for a 64-bit compiler. The float always takes 4 bytes. The character always takes 1 byte. So why is there only variation in the case of integers?
Umm, not always. 32-bit compilers also use 4 bytes as the size of an int.Actually the C language standard says that an int must be at least 16-bits wide. But it doesn't say it has to be exactly n-bits wide. So compiler writers generally go with the word size of the underlying machine - which is 32 bits on most machines today. (Word size is, loosely speaking, the number of bits the processor can physically process at one shot)Coming to why this is so (why int is the only type without a fixed size), int is the only type where you do not 'interpret' the bits stored in memory. The char type uses ASCII encoding. This encoding was not defined by the C language committee, but since they chose to use it, they had to go with ASCII's 1byte wide characters. So the size of a char was fixed. Storage and encoding of float and double are also defined by IEEE standards, so the C language committee had to fix the size of float to 4 bytes. But when it comes to integral types, there is no encoding standards that specifies the number of bytes to use. So the C language committee chose to leave it undefined to allow compiler writers enough leeway to optimise code according to underlying architectures. It is very truly said that C leans towards the convenience of the compiler writer rather than of the high level user. Accordingly, you see compilers merrily changing the size of int, long and long long according to convenience and underlying architectures, but not messing with ASCII or IEEE.
9 people are to be seated in a row. Two of them, A and B, must sit next to each other, and another two, C and D, are not to be seated next to each other. How many different sitting arrangements are possible?
See, I use a simple trick to solve the problems of some persons sitting together and not together as per conditions given that is the bundle method (I call it so).If A and B are to be seated together, we consider them as a bundle tied together as one unit and not two separate units.So, the number of ways in which A and B can sit together in the arrangement of 9 people is 8! as there are 7 indivisuals and one bundle of A and B and they can be arranged in 7 + 1 = 8! ways, also they can interchange position between themselves and hence the number of ways become 2 x 8! ways.Now, numbers of arrangements in which C and D are not together = total number of ways - numbers of arrangements in which C and D are together.So, numbers of ways in which A and B are together and also C and D are together is7! x 2 x 2 as there are 5 indivisuals, 2 bundles and each of them can rearrange in 2 ways within bundle.So, our required answer becomes 2 x 8! - 7! x 2 x 2 = 7! x 2(8 - 2) = 7! x 12.The answer may seem lengthy because I am trying to explain but its the easiest method I know and I suggest to understand it and its going to make u solve questions very fast and easily.Hope it helps…
What are some examples of animals with eight legs?
Spiders, like the Ryuthela nishihirai shown below. (Note that the two short appendages at the front aren’t another pair of limbs. They are pedipalps.)Another spider, the peacock spider. It has fuzzy pedipalps that make it look like it’s wearing white mittens.Scorpions.Whip scorpions! They are also arachnids, but are distinguished from scorpions by their whiplike tail. A bit scary…The tiny relatives of whip scorpions: the microwhip scorpions.Another arachnid, the tick.And if there are scorpions and whip scorpions, then if there are spiders there are also… whip spiders!Daddy longlegs, AKA the harvestman. They indeed have long legs.Book scorpions! These small arachnids look like tailless scorpions with oversized claws.The sun spider. They are actually more closely related to scorpions than to spiders. Some can grow to half a foot long (a subject of urban legends,) but many are quite small.It seems arachnids are the only animals with 8 legs. Octopuses may appear to have 8 legs, but 6 of them are actually arms and therefore do not count.
