In the library at Lenape Elementary School, there are

Phoenix [80]

Solution:

we are given that

In the library at Lenape Elementary School, there are 3/8 as many fiction books as there are nonfiction books.

There are 44 books in the school library.

we have been asked to find How many books are fiction books?

Let there are x non fiction books in the library. Then there will be $\frac{3}{8}x$ fiction books.

Hence we can write

$x+\frac{3}{8}x=44\\\\\text{Now solve for x}\\\\\frac{8x+3x}{8}=44\\\\\frac{11x}{8}=44\\\\11x=44*8\\\\x=\frac{44*8}{11}\\\\x=4*8=32\\$

Hence there are 32 non-fiction books in the library.

and 44-32=12 fiction books in the library.

a quadratic equation has zero real number solutions. which could be the discriminant value associated with this equation? a. –5

Flauer [41]

Answer: Option 'a' is correct.

Step-by-step explanation:

As we know about the discriminant value i.e.

if we have given a quadratic equation :

$ax^2+bx+c=0$

then,

discriminant value will be

$b^2-4ac$

There are 3 properties regarding discriminant value as follows:

$1)b^2-4ac>0\\\\means,\\\\\text{ there exists real zeros}\\\\2)b^2-4ac=0\\\\means,\\\\\text{ there exists equal zeroes}\\\\3)b^2-4ac$

So, here we need a zero real number solutions i.e. there does not exists any real number.

So,

$b^2-4ac=-5$

Hence, Option'a' is correct.
