There could be 12 white marbles and 16 red marbles
You would expect to find 5 red marbles in a bag of 100 marbles if every 20th marble is red.
a bag contains 150 marbles some of the marbles are blue and the rest of the marbles are white in the bag there are 21 blue marbles for every 4 white marbles how many of each color marble blue and white are in the bag show or explain your thinking
put one cup into another cup, then put 5 marbles in each.
if the balls are in the ratio of 7:10, then in every 7+10 = 17 of them 7 are white and 10 are black. With 136 marbles there are 136 ÷ 17 = 8 lots → there are 8 lots × 7 white/lot = 56 white.
There must be 67 marbles.
22 marbles are in the fifth line.
Put several marbles in your mouth, and talk as clearly as you can. Make sure that you say every part of every word, expecially the last letter. Keep your face pointed a little bit toward the floor so you won't choke on the marbles. Practice every day for 3 weeks.
15 20/4 = 5 5*3 = 15
33 marbles must be in the sixth line
A ratio of 4 to 5 is equivelant to saying there are "4 of object A's for every 5 object B's". For example, there may be a ratio of 4 to 5 of red and black marbles in a bag. For every 4 red marbles are in the bag, there are 5 black marbles. Therefore, if there were 12 red marbes in a bag, there would be 15 black marbles in the bag. A= object A; B= object B 4A=5B; A=5B/4 or B=4A/5
The answer is dependent on whether of not you replace the marbles in the jar. If you do, the probability of drawing a red marble is 9 in 15 or 60%, every time. If you do not replace the marbles, the probability of drawing a red marble is 2 in 8 or 25%.
Oh honey, let me break it down for you. If the first line starts with 10 marbles, and each consecutive line has one less marble than the previous line, by the time you get to the seventh line, you'll have 4 marbles. So, grab those 4 marbles and go win that game, darling!
