The list price of a refrigerator is $1899. The chain discount is 20/15. What is the final net price?

shusha [124]

1st = 100% - 20% = 80%
2nd= 100%-15% = 85%

Net Price Factor = 0.8 x 0.85 = 0.68

Net Price = $1899 x 0.68

Final Net Price = $1,291.32

Total Discount= $1899 - 1,291.32 = $607.68

Determine the nature of the roots:

malfutka [58]

Answer:

A. 2 distinct roots.

Step-by-step explanation:

2x^2 + 8x + 3 = 0

Finding the discriminant:

b^2 - 4ac = 8^2 - 4 * 2 * 3

= 64 - 24

= 40

The discriminant is positive but not a perfect square

So there are 2 distinct ,real, irrational roots.

what is the least possible value of the smallest of 99 consecutive positive integers whose sum is a perfect cube

Dmitrij [34]

Let the least possible value of the smallest of 99 cosecutive integers be x and let the number whose cube is the sum be p, then

$\frac{99}{2} (2x+98)=p^3 \\ \\ 99x+4,851=p^3\\ \\ \Rightarrow x=\frac{p^3-4,851}{99}$

By substitution, we have that $p=33$ and $x=314$ .

Therefore, <span>the least possible value of the smallest of 99 consecutive positive integers whose sum is a perfect cube is 314.</span>
