ANSWER IS A I THINK.. hOPE I HELPED! :)
Red- 3
yellow- 4
green- 2
blue- 5
= 14 all together
green- 2/14, 1/7, or 14%
blue- 5/14, or 36%
I don't know what you mean by eat it
Answer:
See example below.
Step-by-step explanation:
The volume of a ball is found using the formula V = 4/3πr³. In this example, you know the volume is 4500π. Substitute V = 4500π and solve for r.
4500π = 4/3πr³
4500 = 4/3r³
3375 = r³
15 = r
This means the diameter of the ball is 30.
Since the box had the same side length as the diameter, this means the volume of the box is V = 30*30*30 = 27,000.
Change both fractions, so they have the same denomater
4 1/5= 4 4/20
3/4= 15/20
change the mixed number into an improper fraction
84/20Subtract 15 from 84
84-15=69
so you get 69/20
Hope this helped :)
<h3>Answer:</h3>
2/15
<h3>Explanation:</h3>
There are 8C2 = 28 ways to choose 2 dimes from the 8 dimes in Annie's purse. There are 21C2 = 210 ways to choose 2 coins from the 21 coins in Annie's purse.
Of the 210 ways to choose 2 coins, 28 of the choices will result in 2 dimes being chosen. The probability of choosing 2 dimes is 28/210 = 2/15.

<em>Comment on nCk</em>
The number of ways to choose k objects from n, when order does not matter, is ...
... n!/(k!(n -k)!)
For the computations above, we have ...
... 8C2 = 8·7/(2·1) = 28
... 21C2 = 21·20/(2·1) = 210
