These drawings depict the steps to get the perpendicular line using a compas (and maybe a ruler)

remember that a line goes through 2 points so we need 2 different points to construct our perpendicular line

the first one is wrong because it doesn't constraint it to be perpendicular
it only has 1 point,

2nd is wrong as well, has only 1 point, the center

3rd is right

4th is correct, hold a sec
how did that 2nd upper arc have same beginig pointn for compass?

3rd on is answer

Write an inequality that represents the missing dimension x

forsale [732]

For this case we have that by definition, the area of a rectangle is given by:

$A = a * b$

Where:

a, b: They are the dimensions of the rectangle.

In the statement we are told that "The area is greater than 12 square inches", then:

$A> 12$

Also we have:

$a = 2\\b = x$

Substituting we have:

$2x> 12$

Dividing between 2 on both sides:

$x> \frac {12} {2}\\x> 6$

Finally we have:

$x> 6$

ANswer:

$x> 6$

A manufacturing operations consists of 12 operations. However, five of the 12 machining operations must be completed before any

shutvik [7]

Answer:

604800 possibilities

Step-by-step explanation:

There are two sets.

The first set is for the first five machining operations. This set has the following operations: A,B,C,D,E

The first operation to be made can be any of them(A,B,C,D,E). The second will be any of the four remaining ones, the third will be any of the three remaining and so on...

So for the first set there are 5*4*3*2*1 = 5! = 120 possibilities.

Now for the second set, the same logic is applied.

There will be 7*6*5*4*3*2*1 = 7! = 5040 possibilities.

Now taking into account all the 12 operations, separated by set, there will be 120*5040 = 604800 possibilities.

You can understand this calculus as that for a simple possibility of the first set, there are 5040 possibilities of the second set. The are 120 possiblities in the first set, so we have the multiplication in the paragraph above.
