Answer:

580

Step-by-step explanation:

Let's translate this word for word.

87 is 15% of what number

87 = 15% times x

87=.15 times x

$87=.15 \cdot x$

Divide both sides by .15

$\frac{87}{.15}=\frac{.15x}{.15}$

Cancel out the common factor of .15 on the right; that is .15/.15=1.

$580=x$

580 is the number

Answer:

580

Step-by-step explanation:

Alright. Translate that into math, and you get:

87=15/100x

multiply both sides by x

8700/15=x

x=8700/15

x=580

Check:

580*15/100

58*15/10

870/10

BINGO!

Which of the following are possible discriminants for a quadratic function that crosses the x-axis twice? Check all that apply.

Sedaia [141]

Answer:

1001

Step-by-step explanation:

If a quadratic function crosses the x-axis twice, it has two solutions. For a quadratic function in $ax^2+bx+c$ with discriminant $b^2-4ac$ , the following is true:

If $b^2-4ac>0$ , then the quadratic has two real solutions
If $b^2-4ac=0$ , then the quadratic has one real solution
If $b^2-4ac$ , then the quadratic has no real solutions

Therefore, in order to have two solutions, a quadratic's discriminant must be larger than 0. The only two answer choices that satisfy this are 1001 and 1.
