2 of the necklaces are blue.
Because she has 8 necklaces in total and 1/4 of those 8 are blue, you would divide 8 by 4.
1/4 of 8 is equal to 2
The ratio of the sides EF/LM after the transformation is 1/8
<h3>
Transformation</h3>
Transformation is the movement of a point from its initial location to a new location. Types of transformation are <em>rotation, translation, reflection and dilation.</em>
Dilation is the increase or decrease in size of a figure by a factor while translation is the movement of a point up, down, left or right.
Given the tansformation:
- (x,y) → (8x, 8y) → (x - 4, y - 4).
- This means a dilation of CDEF by 8 and translated 4 units down and 4 units left.
Hence:
LM = 8 * EF
EF/LM = 1/8
The ratio of the sides EF/LM after the transformation is 1/8

Answer:
0.42
Step-by-step explanation:
use the attached as reference
recall that for a right (90°) triangle, with any acute angle θ,
cos θ = length of adjacent side / length of hypotenuse
in our case, for angle I, the adjacent side is HI = 36 units and the hypotenuse is IJ = 85 units
by the above formula,
cos I = length of adjacent side / length of hypotenuse
= 36 / 85
= 0.42353
= 0.42 (rounded to nearest hundredth)
A) We can first start with the how: our equation is 2x+y=3. First, subtract 2x from each side. We get y=-2x+3. Our Y variable is isolated.
B) Now we can describe which points our equation goes through. One of them is obvious in our form, and that is (0,3) or our y-intercept. Another 2 would be branching off that line, such as (1,1) or (-1,5)
C) To make our system inconsistent, we can easily make another equation, with same slope, but the y-intercept has to be different. Our equation can be y=-2x+2, y=-2x+4, or even y=-2x+3.00000001.
Hope this helps you.
