A. The definition of a ray states that it extends infinitely in one direction. (A line extends infinitely in both directions, and a line segment has two finite end points.) Anything that extends infinitely has an infinite number of points.

36. 50

33. 7

30. 33

Step-by-step explanation:

39. According to the Order of Operations, in this case, Subtraction & Addition are evaluated after Division & Multiplication:

$6 \times 4 + 5 = 24 + 5 = 29$

36. Evaluate everything since everything is wrapped in parentheses:

$(3 + 2) \times (4 + 6) = 5 \times 10 = 50$

33. Evaluate everything inside of parentheses FIRST:

$14 - (8 - 2) - 1 = 14 - 6 - 1 = 7$

Which of the following is the correct ratio for converting kilograms to grams

Brrunno [24]

Answer:

1000 Grams : 1 Kilogram or 1 Kilogram : 1000 Grams

Step-by-step explanation:

In the metric system the value of a kilogram is solved like:

$Kg = \frac{g}{1000}$

When converting from grams to kilograms, we solve it like:

$g = \frac{kg}{0.0010000}$

Let's take for example:

2 KG is how many grams?

We use the grams to kilograms formula like so:

$g = \frac{2}{0.0010000}$

Then we end up with:

g = 2000

Solve 5n^2=5 with the quadratic formula

Yanka [14]

Answer:

n = 1

Step-by-step explanation:

First, rearrange the equation to standard form 0 = ax² + bx + c, when everything equals 0.

5n² = 5

5n² - 5 = 0

State the variables a, b and c.

a = 5; b = 0; c = -5

Substitute a, b, and c into the quadratic formula.

$n = \frac{-b ±\sqrt{b^{2}-4ac} }{2a}$

$n = \frac{-0 ±\sqrt{0^{2}-4(5)(-5)} }{2(5)}$ Substitute

$n = \frac{\sqrt{100} }{10}$ Simplify inside the √ and bottom

$n = \frac{10}{10}$ Simplify the top

$n = 1$ Final answer

Therefore the solution is n = 1.

The quadratic formula usually is written with x, but it can be solved with any variable in standard form.

adoni [48]

Step-by-step explanation

<h3>Prerequisites:</h3>

$b^2 - 4ac = 0 \Rightarrow 1 solution$

$b^2 - 4ac > 0 \Rightarrow 2 solutions$

$b^2 - 4ac < 0 \Rightarrow No\ real\ solutions$

----------------------------------------------------------------

$2x^2-7x-9 = 0$

$b^2 - 4ac$

$-7^2 - 4(2)(-9) = 121$
