What is the mathematic expression pi?
It is a transcendental number, which is a kind of irrational number. It is the ratio of the circumference of a circle to its diameter and is approximately 3.14159
What are some modern examples of math that seem to use the same ideas as the ancient greek math?
Pythagorean Theorem would be the first thing to come to mind. Well, this is kind of more related to art/architecture, but there is the golden rectangle and the golden ratio. The golden ratio is represented by the Greek letter phi, which appears as a circle with a slash going through it. It is a value representing the ratio of the lesser to the greater when the ratio of the lesser to the greater is the same as the ratio of the greater to the whole. In Ancient Greek, architects used this technique to create beautiful buildings and works of art, where the ratio of the length to the width of the rectangle in one of the structures (or vice versa) is equal to the golden ratio.
A number that cannot be expressed as a ratio of two integers or as a repeating or terminating decimal?
It could be what is known as an "irrational number", which is a kind of real number. Alternatively, and at a rather advanced level, it could be a number which is not even a real number.
What does the math term pi mean?
Amongst the many properties of pi is the fact that it is the ratio of the circumference of any circle to its diameter. It is a special kind of irrational number, called a transcendental number. It is roughly equal to 3.14159 (a degree of accuracy that is adequate for most normal purposes) but its value was calculated to 5 trillion digits in Oct 2011. "Pi" (a letter in the Greek alphabet) is the symbol used for the number that is the ratio of the circumference of a circle to the circle's diameter. It's a natural property of circles, and every circle produces the same number: 3.14159... plus more decimal places that never end. Although 'pi' is defined in terms of a property of circles, it crops up in connection with just about every aspect of math, Physics, electronics, etc.
What kind of number is pie?
the number is spelled pi, not pie. Pie is a food, pi is different.Pi is an irrational number (number which doesn't end) which is the ratio to the circumference o f a circle to its diameter.Some beginning numbers of pi are: 3.14159265358979323846264338327950288419716939937510...and so on
What would be the offspring be if a roan cow and a white bull were bred together?
The offspring produced is dependent on chances. We can figure out the chances of the kind of offspring such a cross will get by using a Punnett square. Unfortunately the WYSIWYG format on this site will not allow for such a square, so we will give the ratio, the genotypic and phenotypic percentages that such a cross will receive. Let R = red, W = white and RW = roan. Roan cow (RW) x White bull (WW) Offspring: 2 RW : 2 WW Genotypic ratio: 50% roan and 50% white Phenotypic ratio: Same as above. Thus, the offspring of a roan cow crossed with a white bull (presumably of the same breed, being Shorthorn), may come out as white or roan. There is a 50% chance that either will occur.
What kind of plant always produces offspring with the same trait as the parent(s)?
I think it's a true-Bred plant
What kind of phenotype ratio would you expect from a mono-hybrid cross?
possible mendelian ratios for monohybrid cross genotype is 1:2:1 and phenotype is 3:1
How long does a offspring take?
well it depends on what kind of offspring
What kind of puppy does a Alaskan malamute and a Siberian husky make do they come out as a cross bred or hybrids?
An Alaskan Malamute/Siberian Husky mix is a cross breed and a hybrid because a cross breed is a hybrid. In this case, a hybrid would be defined as the offspring of two different breeds of dogs which is what a cross breed is as well.
What kind of offspring does grizzly bears have?
Grizzly bears offspring are called cubs.
What is the correct meaning of progeny?
Descendants of the human kind, or offspring of other animals; children; offspring; race, lineage.
A red bull when crossed with white cows always produces roan-colored offspring explain how the colors for red roan and white are inherited?
This phenomena is called incomplete dominance. Neither red nor white in this case is dominant to the other. You can also see this when breeding a Charolais (white) to an Angus (black) The offspring are kind of grey.
What kind of offspring do birds lay?
Birds lay eggs.
What kind of offspring are produced from sexual reproduction?
Offspring that are genetically different from its parents. Each parents contributes half the number of chromosomes, therefore the offspring has genes from its mom and from its dad.
What do you get when different breeds of chickens mate and we hatch the eggs what kind of chicken is that?
What you get is a cross breed. This is not always a bad thing. Breeds are born this way but with a lot more work than chance cross breeding. You can get some interesting combination when you do this on a home farm. I have a cross between an Araucana and a Cochin that produces "Gold" colored eggs.
What is the purpose of a ratio?
Well a ratio is kind of used for comparing numbers quickly and accurately.
