Answer: 0.41
Step-by-step explanation: 0.59 is 59%. To find the percentage of chance that it will not rain, you subtract 1 (which is 100%) minus 0.59. You get an answer of 0.41 (or 41% if you prefer.)
The answer is 10w.
40 divided by 4 is 10. The X and Y cancel out, leaving 4W.
Similar figures are the same shape but not the same size. you can find out the scale by using parallel lines.
It would be 3840. The pattern is: x2, x4, x6, x8, x10. Hope that helps! :) :D
