Why does a rational number plus an irrational number equal an irrational number?
from another wikianswers page: say that 'a' is rational, and that 'b' is irrational. assume that a + b equals a rational number, called c. so a + b = c subtract a from both sides. you get b = c - a. but c - a is a rational number subtracted from a rational number, which should equal another rational number. However, b is an irrational number in our equation, so our assumption that a + b equals a rational number must be wrong.
A squared plus b squared equals c squared?
This is the common form of the Pythagorean Theorem. It describes the relationship between the two legs of a right triangle and the hypotenuse.
Perimeter of a triangle where a equals 21 b equals 28 c equals?
49 + c units
What is the answer to a plus b plus c equals 180 b equals 3a c equals 5a?
a + b + c = 180 b = 3a c = 5a Substituting the values of b and c into the first equation. a + 3a + 5a = 180 or 9a = 180 so that a = 20 then b = 3a = 3*20 = 60 and c = 5a = 5*20 = 100
When a squared plus b squared equals c squared what is the square root of the square root of the square root of a squared squared squared plus b squared squared squared?
Since a squared plus b squared equals c squared, that is the same as c equals the square root of a squared plus b squared. This can be taken into squaring and square roots to infinity and still equal c, as long as there is the same number of squaring and square roots in the problem. Since this question asks for a and b squared three times, and also three square roots of a and b both, they equal c. Basically, they cancel each other out.
If a equals b and b equals c then what does c plus b equals?
2a. (a, b and c are all equal.)
If A equals B and B equals C does A equal C?
Yes.
If a equals b and b equals c and c equals d and and d equals e then what does e equal?
They all equal each other. a = b = c = d = e e = a e = b e = c e = d e = e
If a plus b equals 40 b plus c equals 34 and a plus c equals 42 what does b equal?
a=24 b=16 c=18
If a plus b equals c what does a plus c equal?
A+c= 2a+b
What does a equal if b equals 6 and c equals 10?
2
If a plus b plus c not equal to 0 then a divided by b plus c equals b divided by c plus a equals c divided by a plus b prove that a equals b equals c?
Because there is no way to define the divisors, the equations cannot be evaluated.
If a plus b equals c and b plus c equals d and c plus d equals e and a equals 7 and e equals 5 what is a plus b plus c plus d plus e equal?
the answer is a
What does bxc equal?
It equals b times c.
Is it true that if a intersect b equals a intersect c then b equals c?
No. Suppose A = {1,2}, B = {1,2,3,4,5,6} and C = {1,2,3,5,7,11}. The intersection of A with B is {1,2}, the intersection of A with C is also {1,2}, but B is not equal to C.
What is the difference between equals equals and equals in C programming?
a = b changes the value of a and makes it the same as the value of b. a == b does not change the values of a or b. It is an expression that is equal to 1 if a and b are the same or to 0 if a and b are different. For example: if ( a == b) { c = d;} means if a and b are the same, then set c equal to d. C does let you write the following: if ( a = b) { c = d;} This sets a equal to the value of b, and then if the new value of a is non-zero, it sets c equal to d. You can do this, but if you see a single equal sign in an "if" condition, that usually (but not always) is a mistake.
If vector c equals vector a plus vector b under what circumstances does c equal a minus b?
When b is zero.
