10 Green marbles, 13 Blue marbles.
A sack contains red and blue marbles the ratio of red marbles to blue marbles is 4 3 if there are 18 blue marbles in the sack how many red marbles are in the sack?
24 red marbles
24 red marbles is 40 percent of what marbles?
35
A bag of marbles has twice as many blue marbles as green and the bag has at least 33 marbles in it at least how many green marbles are in the bag?
There are at least 11 green marbles in the bag.
Jerry has a total of 23 marbles The marbles are either blue or green He has three more blue marbles than green marbles How many green marbles?
Let X = the number of green marbles. X+3 = the number of blue marbles. X + (X+3) = 23 2X + 3 = 23 2X = 20 X = 10 or the number of green marbles.
Why do ships dump ballast water?
Ships dump ballast water to counter any weight they take on, or to decrease their draft.
What is main ballast of a vessel?
Ballast used to be stones. With the invention of the electric pump, I think most ships will actually pump water into and out of tanks to adjust their ballast now.
What liquid makes ships lower?
Ballast tanks contain water, usually sea water.
What is void space in ships?
Void space is an empty compartment not used for cargo or ballast purpose.
What are the buds useds for on a plant?
it turns into the flower.
What temperature scale useds the abbreviation k?
Kelvin
Do ships in the general lakes need more or less ballast than ocean-going ships?
Ships need more ballast in the ocean because the salt helps to keep them a float.What we know is that salt water is about 3% more dense than fresh water and that ships use the water they are floating in for ballast.Say an ocean ship needs 10 tonnes of ballast to get to it's stable water line. The volume of 10 tonnes of seawater would equal 9.7m3.That same ship will float slightly lower in fresh water since fresh water is less dense. It will need 3% less ballast weight (9.7 tonnes) to get to the same stable water line in fresh water. The volume of 9.7 tonnes of fresh water would equal 9.7 m3.So, the ship in the ocean requires 3% more ballast weight than the ship in fresh water, but the ballast volume is the same in both cases.

What is the ballast of a ship usually made of?
Ballast on smaller vessels is often water,high density materials like concrete or iron or just the weight of the crew. On larger vessels such as container ships,it is a combination of water and cargo.
What force that cause the ships to list?
The force may be gravity if the cargo or ballast are incorrectly stowed. On a sailboat it is more likely to be the wind.
How was the round goby brought into the US?
Ballast water in cargo ships, brought over from the Black, Caspian, Marmara, and Azov seas.
Why do ships float while submarines sink?
Submarines are designed with enough ballast and control systems to allow them to submerge and surface as needed.Surface ships are designed only with enough ballast and control systems to keep them on the surface. While they can sink just as well as submarines can, their ability to re-surface without a salvage operation is non-existent.
