What are the least numbers of packs of yellow marbles and blue marbles a person would have to buy t ohave the same number of each color of marble?
That would depend on how many yellow and blue marbles are in a pack. If yellow and blue marbles are sold separately and there are the same number of marbles in a pack, buy one of each. That's probably not the case.
Can objects have different weight but same volume?
Yes. A good example would be styrofoam and steel. The same volume of each of these substances would make for vastly different weights.
If there are 14 white marbles and 28 red marbles what is the probability that you would pick a white marble?
14/42. You have to add the amount of marbles and then put the probabilityof answers you're looking for. Ex: 14 white marbles 28 red marbles 14+28=42 ?/42 your looking for the probability of white marbles, so you put in the amount of white marbles on the fraction. =14/42
Are marbles magnetic?
Not if it is a glass marble, but you can get metal marbles which would be magnetic in many cases.
The number of red marbles varies inversely as the square of the number of blue marbles when there were 4 reds there were 20 blues How many reds would there be if there were only 4 blues?
Indirect variation: the numbers of red marbles = k/the square of blue marbles, where k is the coefficient of the variation. 4 = k/202 4 = k/400 1600 = k Let the number of red marbles be x. x = k/42 x = 1600/16 x = 100 Thus, if there were 4 blue marbles, would be 100 red marbles.
