Joyce estimates that a piece of wood measures 5.5cm If it actually measures 5.62cm, what is the percent error of Joyce’s estiimate? Round to the nearest whole number

%2.1352

(Rounded =%2.1)

Step-by-step explanation:

5.5/5.62=0.978648

1.0 - 0.978648= 0.021352

(Move the decimal over 2 places to the right to convert to percent)

002.1352

%2.1352

(Rounded =%2.1)

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'.
