17. The mass of a length of metal wire is 57g. When the wire is placed in a graduated cylinder with water, it displaces 12mL of water. What is the density of the wire? * 4.75 milliliters
4.75 cubic centimetres
0.21 milliliters
0.21 cubic centimeters

  4.75 g/cm³

Step-by-step explanation:

Density is the ratio of mass to volume. The density of the wire is ...

  (57 g)/(12 mL) = 4.75 g/mL = 4.75 g/cm³

__

The usual units for density are g/cm³ or kg/m³. None of the offered choices seems to have the correct units.

i dont know

step-by-step explanation:

for the friend request.

when a figure, such as triangle (xyz) is reflected over the line y = x to create x'y'z' the x-coordinates and y-coordinates of the original image (pre-image) will be reversed for the image. (e.g., (x, y) > (y, x)) this means that the pre-image position of the x- and y-coordinates switch places which in turn provides a mirror like image of the original xyz.  

i notice that when i draw a line segment from x to x', that the points are parallel from each other -- they are exactly across from each other and do not intersect with any other points.  

yes, think i would see the same characteristic if you drew the line segment connecting y with the reflecting line and then y' with the reflecting line because of the essence of reflections. because it is a mirror image, each point was effected the same way which leads me to conclude that they same would apply to y and y'.
