The ratio of the side length of square A to side length of square B is 4:9. The side length of square A is 12 yards. What is the
Nadusha1986 [10]
Answer: the perimeter is 108 yards. Here are the steps:
A:B
4:9 (Ratio of side A to side B.)
12:27 (A was increased 3x, so B needs to be increased 3x to keep above ratio the same when simplified. Ex. 15:20 simplifies down to 3:4.)
27+27+27+27=108yds (Perimeter is all of the sides added up.)

Hope this helps. :)

How do you answer this??
dezoksy [38]
<h3>Given</h3>
  • a rectangle x units wide and y units high divided into unit squares
<h3>Find</h3>
  • The total perimeter of the unit squares, counting each line segment once
<h3>Solution</h3>

For each of the y rows of squares, there are x segments at the top, plus another x segments at the bottom. The total number of horizontal segments is then

... horizontal segment count = (y +1)x

Likewise, for each of the x columns of squares, there are y segments to the left, plus another y segments to the right of the entire area. Then the total number of vertical segments is

... vertical segment count = (x+1)y

The total segment count is ...

... total segments = horizontal segments + vertical segments

.. = (y+1)x +(x+1)y

... total segments = 2xy +x +y

_____

<u>Check</u>

We know a square (1×1) has 4 segments surrounding it.

... count = 2·1·1 +1 +1 = 4 . . . . (correct)

We know the 3×3 window in the problem statement has 24 segments.

... count = 2·3·3 +3 +3 = 18 +3 + 3 = 24 . . . . (correct)

We know a 1×3 row of panes will have 10 frame elements.

... count = 2·1·3 +1 +3 = 6 +1 +3 = 10

It looks like our formula works well.

State the missing reason in this flow proof
natali 33 [55]

The complete flow proof is:

  1. <em />\angle 5 = 40^o<em> ---- Given</em>
  2. <em> </em>\angle 2 = 140^o<em> ---- Given</em>
  3. <em />\angle 5 + \angle 2 = 180^o<em> ----- </em>\angle 5<em> and </em>\angle 2<em> are supplementary angles</em>
  4. <em />\angle 5 + \angle 2 = 180^o<em> ----- </em>\angle 5<em> and </em>\angle 2<em> are same-side interior angles</em>
  5. <em />a ||b<em> ----- Proved</em>

We have:

\angle 5 = 40^o

\angle 2 = 140^o

<u>The proof of </u>a ||b<u> is as follows:</u>

The first statement is:

\angle 5 = 40^o ---- Given

The next statement is:

\angle 2 = 140^o ---- Given

Supplementary angles add up to 180^o.

So, the third statement is:

\angle 5 + \angle 2 = 180^o ----- \angle 5 and \angle 2 are supplementary angles

Same side of interior angles add up to 180^o.

So, the fourth statement is:

\angle 5 + \angle 2 = 180^o ----- \angle 5 and \angle 2 are same-side interior angles

Because the angles are supplementary angles and also same-side interior angles, then it means that <em>line a is parallel to line b</em>

So, the last statement is:

a ||b ----- Proved
