All up there are 20 marbles and only 6 of those are chances of winning so we make it into a fraction 6/20 then times 20 by five to get to 100 (what ever we do to the bottom we do to the top) times 6 by five giving you a fraction of 30/100 then divide 30 by 100 giving you 0.30 ANSWER EQUALS = 0.30

What is the area of the figure abcd
expeople1 [14]

Answer:

66 square inches

Step-by-step explanation:

The area of the figure can be found by adding the area of the rectangle and the triangle together.

The area of a rectangle is found A = l*w. Here l = 10 and w = 6. So the area of the rectangle is 10*6 = 60.

The area of a triangle is found A = 1/2 b*h. Here b = 2 from 12-10 = 2 and h = 6. So the area of the triangle is 1/2 * 2* 6 = 6.

The area together is 60 + 6 = 66 square inches.
