Answer:
Step-by-step explanation:
Hi Millie.
First we can realize that the number of cubes of each type does not matter, only the ratios between them. We see that if there are x yellow cubes, there are 3x blue cubes. And therefore, there are 5*3x green cubes, or 15x green cubes. This means that the cubes are in a 1:3:15 ratio, or that for every 1 yellow cube, there are 3 blue and 15 green cubes.
Now we can find the probability of picking a yellow cube. Since there are 18 non-yellow cubes for every yellow cube, this means that there is a 1/19 possibility of picking a yellow cube.
A=2πrh+2πr2=2·π·6·25+2·π·6^2 so the answer is D
<h3><em>(8)2+(x)2=(10)2</em></h3><h3><em>64+x2=100</em></h3><h3><em>x2=100-64</em></h3><h3><em>x2=36</em></h3><h3><em>x=6</em></h3><h3><em>BE = 6</em></h3><h3><em>hope it helps..stay blessed...thank you....</em></h3>
