Hello,


ABCD is a diamond.
Let's D' the intersection of the circle and DC.
m∠BCD'=2*m∠BDC=2*45=90°
m∠BCD=90°
The diagonals of ABCD are perpendicular==>ABCD is a diamond  and AB=BC=CD=DA=2

So, the line is going to the <em>right. </em>This is a positive association. If it was going to the left, it would be a negative association. 

It's not super strong, so I would say:

"weak positive association" or "B". 

I hope this helps!

Rewrite each sum as a product of the Gcf of the addends and another number. 15+45
morpeh [17]
15 + 45

GCF = 15

15/15 = 1
45/15 = 3

(15 * 1) + (15 * 3) = 
15(1 + 3) <===

There are 10 circles and 2 triangles. What is the simplest ratio of triangles to total shapes?
barxatty [35]

Answer:

1:6

Step-by-step explanation:

Given that there are 10 circles and 2 triangles, the total number of shapes is equal to 10+2.

10+2=12

Because there are 2 triangles, the ratio of triangles to total shapes is equal to 2:12.

However, this ratio can be simplified because both sides are multiples of 2. Divide both sides of the ratio by 2 to simplify the ratio.

2:12

1:6

Therefore, the simplest ratio of triangles to total shapes is 1:6.

I hope this helps!
