Answers

3.4, 13, 18.4, 44.3, 82.4, 49.3 :) hope this helped

3.44 = 3.4 since 4 in the hundredths is nearer to 0
12.09 = 12.1 since 9 is near the next digit
Do the same with these:
18.39 = 18.4
44.347 = 44.3
82.383 = 82.4
49.2532 = 49.3

What is 1/4 divided by 6

Answers

1/4 ÷ 6

= 1/4 ÷ 6/1

= 1/4 × 1/6 When the ÷ sign changes to × the fraction 6/1 changes to 1/6

= 1/24

1/4 divided by 6 equals:

0.0416666667

Three vertices of a rectangle are (–3, 4), (5, 4), and (5, –2).

What are the coordinates of the fourth vertex of the rectangle?

A. (–3, –4)

B. (–3, –2)

C. (5, –3)

D. (5, 2)

Answers

$A =(-3, 4), \ \ B= (5, 4),\ \ C= (5, -2)\n \n The \ slope \ of \ AB : \n \n \n m= (y_(2)-y_(1))/(x_(2)-x_(1) ) = (4-4)/(5+3)=(0)/(8)=0\n \n The \ slope \ of \ CB :\n \n m= (y_(2)-y_(1))/(x_(2)-x_(1) ) = (5-5)/(-2-4)=0$

$The \ slope \ of \ lines \ parallel \ is \ the \ same \n \nTo \ find \ the \ coordinates \ of \ the \ fourth \ vertex, \ add \ the \ coordinates \n of \ A \ and \ C \ together, \ and \ subtract \ the \ coordinates \ of \ B. \n \n The \ fourth \ vertex \ is: (-3+5-5; 4-2-4) = (-3, -2) \n \n Answer: \ B. \ \ (-3, -2)$

The rectangle doesn't necessarily have to be standing up straight or laying down flat
on the graph. It could be tilted ... leaning. Dealing with those coordinates would be
a nightmare, and since you're in Middle School and just learning this stuff, we can be
pretty sure that the rectangle in this problem is straight on the graph.

If we think about it for a second, and visualize a rectangle in our mind, we realize that:

-- Both top corners have the same y-coordinate.
-- Both bottom corners have the same y-coordinate.
-- Both corners on the left side have the same x-coordinate.
-- Both corners on the right side have the same x-coordinate.

The first two points given in the question are ( -3, 4) and (5, 4).

-- They have the same y-coordinate, so they must be either the top
or the bottom two corners.

-- We also know right away that the left side of the rectangle is at x = -3
and the right side of the rectangle is at x = 5 .

Now look at the third given point ... (5, -2) .

-- Its x-coordinate is 5 so we know it's a corner on the right side.

-- But we already had one corner on the right side ... the point at (5, 4).
This new one is lower.

-- So now we know that (5, 4) was the upper right corner, (-3, 4) was the
upper left corner, and this new point is the lower right corner.

All we're missing is the lower left corner.

We know now that the left side is at x = -3 and the right side is at 5 .
We also know now that the top is at y = 4 and the bottom is at y = -2 .

So the bottom left corner is (-3, -2). That's choice - 'B' .

The first step we can take to find the simplest form of this inequality is to subtract 3 from both sides

$(1)/(2)$ n + 3 < 5

$(1)/(2)$ n + 3 - 3 < 5 - 3

$(1)/(2)$ n < 2

So now we have a simpler version to work with.
To further simplify, we can divide both sides by $(1)/(2)$ . Dividing by fractions is hard though, so smart people have found out that dividing by a fraction is the same as multiplying by that same fraction's reciprocal.

$(1)/(2)$ n / $(1)/(2)$ < 2 / $(1)/(2)$

$(1)/(2)$ n * 2 < 2 * 2

Now, we can work it out to find the completely simplified inequality, which would simply be

n < 4

The character '<' represents that the number being represented by the variable is less than the number that follows that character. On a proper number line, this is represented by an open circle above the number on the right of the inequality with an arrow pointing the same direction on the number line that the point of the inequality symbol is facing.
If that doesn't make sense, imagine the inequality symbol as the head of an arrow.

<====<<

So the arrow would be pointing to the left, with an open circle above the 4. The only choice listed that represents this is the second option down.
Option B is your correct answer choice.
