A boy bought an article for £9. He spent £4

Marina86 [1]

Answer:

Profit % = 39%

Step-by-step explanation:

Cost price of the article = 9

Price for repairing = 4

Therefore, Total cost of the article = 9 + 4 = 13

Selling price of the article = 18

Profit = 18 - 13 = 5

Hence,

$Profit \% = \frac{Profit}{Cost \ price} \times 100\\\\$

$= \frac{5}{13} \times 100\\\\=38.46 \%\\\\=38.5 \%$

Profit percent (to the nearest %) = 39%

If the discriminant of a quadratic equation is equal to -8, which statement describes the roots?

sp2606 [1]

Answer:

Step-by-step explanation:

A discriminate of -8 is never going to give you a real root. D is wrong

You cannot have just 1 complex root, nor can you have just 1 real root unless the discriminate is 0. A and C are both wrong for the same reason. 1 complex root is impossible. They come in pairs.

So the answer is B. You have 2 complex roots.
