How is rounding used in everyday life?
when someone asks you the time, you rarely respond with it is eleven twenty three and fourteen seconds, you typically say its eleven twenty five.

I sometimes use radicals for a quick and dirty error estimation on a questionable statistic, especially in baseball. Very roughly speaking, the error of a stat is its radica…l (square root), e.g. if a batter is 4 for 10 against a particular pitcher, the announcers sometimes get a little crazy and start lauding his .400 average!. Well I say, wait a minute, roughly speaking, those four hits have an error of plus or minus two hits for every 10 at bats. That gives an acceptable batting average range within error of .200 to .600, which basically tells you that you clearly don't have enough data yet to make any sort of analysis on that stat.
Hydrogen is found in water, carbohydrates, fats and proteins which is contained in the food we eat.
Petroleum is used in different forms to propel almost all vehicles, - cars, trucks, trains, ships and aircraft all run on some sort of petroleum. Oils, lubricants for machin…es and you skin(vasoline), some household product and even make-ups have petroleum based/by products. Asphalt/tar and some plastics.

Everything in life is math. Money spending or saving is math, building is math! Etc! Our lives revolve around math

It's most commonly used in photography in Xenon flash units as its a noble gas and doesn't react with other chemicals or get used up- when a high voltage is put through the ga…s it emits a bright white light- the charge is stored in a capacitor the quickly dumped through the tube containing the gas in a quick burst - most mobile phones now have this type of flash as well - previously it was done by a high band (high blue colour ,almost white) LED (light emitting diode) most red eye reducing cameras have both -LED for anti red eye then a Xenon flash for the picture! Of course its used in neon signs as well! - The effect is related to plasma discharge were the electrons in the voltage field are excited and release photons ( bit of light) which we see. If you have a look at the Periodic table ( the list off elemental chemical (it's in every chemistry book) it will be on the far right side with the other Nobel gases the list runs downwards and includes Argon etc.. all of these do the same thing and light up when a voltage is put through them- but they all give off a different colour- this is what gives you all the different colours in Neon signs!
We use wheels for: . Transportation: Cars, Trucks, motorcycles, bicycles, buses, trains, etc. . Making heavy machinery mobile: Cranes, loaders, bulldozers, backhoes, et…c. . Making weapons mobile: Tanks, canons, multi-tube rocket launchers, etc. . To help aircraft take to the sky and land again. . Fun: Roller coasters, dodgems, etc.
They help chemical reactions take place where they would either not take place at all or would only take place at much higher energies.
Every day we neutralize things inside and outside of our bodies without even knowing. When we suffer acidity we take milk of magnesia. Even your body alone neutralizes, diges…tion is the best example of acid- base neutralization. However, even when an ant stings the skin and baking soda is applied on the skin for relief, neutralization takes place. Ant sting is acidic and baking soda is basic. Wasp stings on the other hand are basic and vinegar is used for relief on wasp sting, we are still neutralizing. In baking, Use of baking soda in cooking may be for the leavening effect (release of CO2) but it needs a neutralizing reaction to release the CO2. The list is endless.
Much of the sun's heat is in infra red. The earth would be a frozen block if it were not for IR. More trivially, most tv remote controls work on infra red frequencies.
One example of everyday use of a database is the telephone directory. Another is your own personal address book. You might also refer to the contents page or index of a boo…k, or use a dictionary to look up the meaning, pronunciation or origin of a word; these are everyday databases, as are encyclopedias. Schools keep a list - a database - of all students attending, and of students attending each individual class, as well as of all staff employed by the school; all employers keep databases of their employees.
Symmetry is often seen everyday by people of all ages in nature. Symmetry that we see everyday in nature is most often Bilateral Symmetry. This means that the two halves of an… object are exactly mirror images of each other. Symmetry in humans the human face has a line of symmetry in some places, but some faces are more symmetrical than others. The more symmetrical your face the prettier your face will appear. A perfect example of this is supermodels and actresses. Another example of human symmetry is the kidneys, lungs, and the brain. If you draw a line or slice these organs in half, you will have a mirror image of the other. In flowers there are roughly identical petals, sepals, stamens, and leaves. While at the beach there are a wide variety of shells and underwater life with a line of symmetry, an example of this is a crab, a lobster, octopus, and starfish. Crystal G.
