Answer:
The answer to your question is 175 gallons
Explanation:
Data
60% antifreeze solution volume = ? = x
25% antifreeze solution volume = 25%
Final concentration 50%
Process
0.6x + 0.25(70) = 0.5(70 + x)
Simplification
0.6x + 17.5 = 35 + 0.5x
0.6x - 0.5x = 35 - 17.5
0.1x = 17.5
x = 17.5/0.1
Result
x = 175 gallons
A a solid is the correct answer
Answer:
New cells arise from existing cells.
Explanation:
According to the cell theory, "all living things are composed of one or more cells; the cell is the basic unit of life; and new cells arise from existing cells"(Lumen Learning).
Cells are the basic unit of life. Some organisms consists of only one cell while other organisms have many cells and are called multicellular organisms.
In multicellular organisms, new cells are formed by the division of preexisting cells.
Nuclear fusion and fission are two atomic processes that release tremendous amounts of energy. The primary difference is that in fission, heavier atoms are broken down into smaller ones, while smaller atoms join together to form heavier ones in fusion.
The process of fission is the one that is used in atomic bombs and nuclear power plants. Fusion requires a large amount of energy to be started and is the energy production process for stars.
A compound is a substance made up of atoms of two or more different elements joined by chemical bonds. A mixture is a combination of two or more substances that are not chemically combined.
