What is 80 percent off of 20 dollars?
The amount after the discount is $4.00
Suppose 60 percent is the same as 0.6 decimal 3 percent is the same as what?
3% = 0.03 And there is no need to SUPPOSE that 60% = 0.6. It is.
Why all numbers other than square numbers have an even number of factors?
Consider a number k. Let m be the square root of k : since k is not a square number, m is not an integer and so m cannot be a factor of k.Suppose p is a factor of k and suppose p< m.Then k has another factor q such that k = p*q and since p < m, then q> m.Thus, for every factor smaller than the square root, there is another factor that is larger than the square root. That is, the factors come is distinct pairs and so there is an even number of factors.
What equation shows that k is one more than twice m?
K is two times m add 1 k = (2 m ) + 1 k=2m+1
If k equals 1000 than m equals what?
We need a formula to work this one out.If k = m, then m - 1000If k = 2m, then m = 500If k = 0.5m, then m = 2000You need to provide us with more information before we can answer this.
