Answer:
$59
Step-by-step explanation:
You first need to find what 18, 27, and 36 can all fit into.
108 is divisible by each of these values:
108/18= 6 108/27=4 108/36=3
This will equate to how many packages of each item you will need:
6 pkgs of Plates, 4 pkgs of Cups, 3 pkgs of Forks
6*$2=12 4*$8=32 3*$5=15
Add these values to find total: 12+32+15=$59
0.75 because 100cm = 1m so you just move the decimal to the right by 2
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>.
