Point A is located at (3,-6) and point A is located at (1-2). What is the scale factor?

Answer:

The scale factor is 3.

Step-by-step explanation:

Let the origin O(0,0) is the reference point and the coordinates of the point A are given by (3,-6).

Therefore, the distance OA is given by \sqrt{(3 - 0)^{2} + (- 6 - 0)^{2}} = 3\sqrt{5} units.

Again, the coordinates of point A' are (1,-2).

Therefore, the distance OA' is given by \sqrt{(1 - 0)^{2} + (- 2 - 0)^{2}} = \sqrt{5} units.

Hence, the scale factor is \frac{OA}{OA'} = \frac{3\sqrt{5} }{\sqrt{5}} = 3. (Answer)

The nutrition facts label on a container of dry roasted cashews indicates there are 161 calories in 28 grams. You eat 9 cashews
kati45 [8]
Divide calories by grams so 161 / 28= 5.75 now you know 1 gram has 5.75 calories so you multiply 5.75 * 12 to get 69. so 12 grams of <span>cashews = 69 calories </span><span />

Xelga [282]

Answer:

21

Step-by-step explanation:

To solve the  problem you can just leave the negatives behind for a while.

You then divide 294 by 14 using the normal method of division you prefere.

The answer you get is 21.

So now when the signs of the numbers are the same (negative or positive) The answer after dividing is always a positive number thus the answer remain 21.

Points A,B, and Care collinear, Point B is between A
melomori [17]
<h3>Answer: x = 4</h3>

===============================================

Explanation:

Saying "Points A,B, and C are collinear" means the three points all fall on the same line. For the sake of simplicity, assume the line is horizontal.

Since B is between A and C, we know that the order of the points from left to right is A, B, C.

Through the segment addition postulate, we say,

AB+BC = AC

(x+3) + (x) = 11

x+3+x = 11

2x+3 = 11

2x = 11-3

2x = 8

x = 8/2

x = 4

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

Extra info:

Using x = 4, we see that

AB = x+3

AB = 4+3

AB = 7

Note how this adds to BC = x = 4, getting us,

AB+BC = 7+4 = 11

which is the length of segment AC. This confirms AB+BC = AC is true and confirms our answer.
