There are 19 marbles total, when you add up all the colors. There are 8 blue marbles, so that's 8 out of 19, AKA 8/19. If you draw a blue marble and don't replace it, that's one less blue marble, and one less marble in general, AKA 7/18. So, now there are 18 marbles since you have drawn the blue one and haven't replaced it. There are 7 green marbles, and the total of marbles is 18 now. So, the chances of drawing a green marble is 7/18!

The figure below has to be covered with multi-colored cloth. What is the area of the cloth in sq mm that is needed?
Georgia [21]

Answer:

26,250 sq mm^2

Step-by-step explanation:

First i cut the shape so its a rectangle on the top and there is a vertical rectangle. Then you find the lengths and to do that for the first rectangle(the horizontal one) you add 75, 75 and 75 to get the length. Then multiply 225(the sum of the 3 75s) by 75 (width) which gets you 16,875.

That is the area of the first rectangle

Now for the vertical rectangle you simply multiply the length and width, 75x125. That equals 9,375. Now add.

9375+16875= 26250!!!!
