Please help i not are very good in math really please guys

9/20=0.45

Step-by-step explanation:

If we calculate the total number of squares we will find that there are 100 one

45 are colored so our fraction is :

9/20 = 0.45

which is 0.45 in decimal form.

Step-by-step explanation:

There are 45 colored squares and in total 100 squares. As a fraction, it is going to be which is .

The fraction sign is the same as division. Dividing a fraction will get us a decimal number.

= 45 ÷ 100

45 ÷ 100= 0.45

45/100 simplified is 9/20.

I hope this helps :)

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'.
