Answer:

100% chance. I don't know if you mean a certain color. We need to know that color if you want us to help you. But, if you really just want to pick a marble, replace it, and pick another, you will ALWAYS get a marble.

Find the area of the figure to the nearest hundredth.
Alecsey [184]

Answer:

=31.64ft^2

Step-by-step explanation:

Triangle

A=\frac{h_{b}b }{2} \\=\frac{4*6}{2}\\=12ft^2

Semicircle

A=\frac{\pi r^2}{2}\\=\frac{\pi 2.5^2}{2} \\=9.82ft^2\\

because both semicircle are the same just multiply by 2

9.82*2\\=19.64ft^2

Now add all together

12+19.64\\=31.64ft^2
