Answer:
Any rational number (that is, a fraction in lowest terms) can be written as either a terminating decimal or a repeating decimal . Just divide the numerator by the denominator . If you end up with a remainder of 0 , then you have a terminating decimal.
Step-by-step explanation:
Convert the fraction 7/12
to a decimal.
7/12=0.583¯
This is a repeating decimal.
The bar over the number, in this case 3, indicates the number or block of numbers that repeat unendingly.
When you need to visually compare two things, that's when you would use a graph. (That is for qualitative data.) Of course, when you need quantitative data, nothing is better than an equation.
So if she still has $27.12, then during her call, she used a total of $2.88.
$2.88 = 288 cents.
Therefore 288 divided by 6 = 48
Therefore the answer is 48 minutes.
Answer:
Discriminant: -4
No real solutions
Step-by-step explanation:
You might remember this long, seemingly very hairy thing called the <em>quadratic formula</em> from earlier in algebra:
The <em>discriminant</em> of a quadratic equation of the form is that bit under the square root: . What does the discriminant tell us? Since we're taking its square root, we know that is only real for non-negative values of . If , we have two real roots, one for and one for . If , the function has a rational root, since the formula becomes
In your case, we have the equation ; here, , , and , so our discriminant is . Since we'd have a negative under our square root in the quadratic formula, we have <em>no real solutions</em>.
