What is the volume of 4 marbles using water displacement?
We don't know what size marbles you have, so we can't tell you their volume.But we can tell you that you had better get the same answer no matter whatmethod you use, otherwise something is definitely fishy. The answer never dependson what method you use to find it.
What is the number of each colour of marbles in a bag of 76 marbles if the ratio of red marbles to green marbles is 2 to 3 and the ratio of green marbles to blue marbles is 9 to 4?
The ratios are: red : green = 2 : 3 = (2×3) : (3×3) = 6 : 9 green : blue = 9 : 4 → ratio of red : green : blue = 6 : 9 : 4 There are 6 + 9 + 4 = 19 parts 76 marbles ÷ 19 parts = 4 marbles per part → red: 6 parts = 6 × 4 marbles per part = 24 red marbles → green: 9 parts = 9 × 4 marbles per part = 36 green marbles → blue: 4 parts = 4 × 4 marbles per part = 16 blue marbles To check: red + green + blue = 24 marbles + 36 marbles + 16 marbles = 76 marbles in the bag.
How can you calculate the volume of a sample of marbles?
Either: 1) Find the radius of each marble and thus their volume through V = 4/3 x pi x r^3 and then add the volumes up. or 2) Put all the marbles in a measuring jug and fill it up to the top. Pour the water into a separate container and empty the marbles out of the jug. Pour the water back into the jug. Thus: Volume of water with marbles - volume of water without the marbles = volume of marbles
If 2 marbles are drawn simultaneously at random from a box containing 6 red marbles 4 white marbles and 4 blue marbles what is the probability that neither of the marbles is white?
45 __ 91
What is the ratio of 4 blue marbles to 6 white marbles?
The ratio of 4 blue marbles to 6 white marbles can be said as 4:6, 4 to 6, or 4/6. This can then be simplified to 2:3 by a factor of 2.
What is the water displacement to find the volume of four marbles?
You fill your displacement cup with water until the hole is finished dripping. Then, you're going to add the four marbles that you asked for. But before you add the marbles inside the displacement cup, you must place a graduated cylinder under the hole in the displacement cup so you can find the volume of a marble. When you discover your results, divide how much water is in the graduated cylinder by the number of marbles you inserted. In this case, it would four.
Pour some water into jar of marbles?
Pouring water into a jar of marbles will displace the marbles and fill the empty spaces between them. This demonstrates the principle of displacement, where the volume of water poured into the jar equals the volume of the marbles that are moved aside to make space for the water.

How can you determine density of a mrble?
Use a scale to find the mass of several marbles. Put some water in a graduated cylinder. Take a reading. Place all the marbles in the grad. cylinder with the water, which will rise. Take another reading. Make sure the marbles are completely submerged. Subtract the 2 readings. This gives the volume of the marbles. This is called the water displacement method. Divide mass by volume. This gives you the density.
What procedure would you use to find the density of the marbles?
To find the density of marbles, you would measure the mass of a certain number of marbles using a balance scale, then calculate the volume by either measuring the dimensions and using a formula for the shape of the marbles or by displacement method with water. Finally, divide the mass by the volume to determine the density of the marbles.

What happens if you pour water into a jar full of marbles?
When you poor water into a jar full of marbles, the water will fill the spaces between the marbles; bubbles will also appear.
What are 'water marbles' made from?
Water marbles are typically made from a superabsorbent polymer, which can absorb and hold large amounts of water. When placed in water, these polymers expand and form spherical shapes that resemble marbles.
If you put marbles in the water what happens?
It either floats or sinks...put the marbles in water to test them!
