If the diameter of a sphere is doubled, its surface becomes

hodyreva [135]

Volumes scale as the cube of a corresponding dimension. Therefore, if the radius of a sphere is doubled (r becomes 2r), the surface area becomes 2 squared, or 4 times the original surface area. The volume would become 2 cubed, or 8 times the original volume.

Answer:

4 blue marbles

Skills needed: Number Theory, Fractions

Step-by-step explanation:

1) The problem tells us that the jar contains marbles that are either red, green, or blue (No Other Color).

It also mentions that $\frac{2}{5} (\frac{4}{10})$ of the marbles are red

and that $\frac{1}{10}$ of the marbles are blue

- The given statement is that 20 marbles are green, and we need to find out the number of blue marbles.

2) We need to first find out the total number of marbles, and then multiply that by $\frac{1}{10}$ to get the # of blue marbles.

---> Given $\frac{4}{10}$ are red and $\frac{1}{10}$ are blue, $1-\frac{1}{10}-\frac{4}{10}$ of the marbles are green (since fractions add up to 1 whole)
