Answer:
10/9x
Explanation:
Start with:
8x/3x+6 // 12x^2/5(x+2)
Factor out 3 then multiply the ricprocal of that fraction:
8x/3(x+2) * 5(x+2)/12x^2
Reduce the expression with x+2, then x,
8x/3 * 5/12x
Reduce numbers w/ GCD 4
2/3 * 5/3x
Lasty, multiply the fractions [multiply numerators&denominators seperatly]
2*5/3*3x
and you get...
10/9x [yayyyy!]
Answer:
1.
Nearly all helium on Earth is a result of radioactive decay. The decay product is primarily found in minerals of uranium and thorium.
In what is called radioactive emission of "alpha particles" the atom of, say uranium, spits out particles in the form of two protons and two neutrons--a helium nucleus.
2.Helium is obtained through natural gas as it is extracted from the ground. The helium is a result of the decay of thorium and uranium. As these elements decay, they release an alpha particle. That alpha particle is the nucleus of a helium atom.
3.Natural gas is separated into its major components through a distillation process known as fractional distillation. Sometimes this name is shortened to fractionation, and the vertical structures used to perform this separation are called fractionating columns. In the fractional distillation process, the nitrogen and methane are separated in two stages, leaving a mixture of gases containing a high percentage of helium. At each stage the level of concentration, or fraction, of each component is increased until the separation is complete.
Explanation:
I would say C.
Dams don't use any chemical means to get their energy output, so B and D are out. A converts to potential energy which can't produce electricity without being set in motion, so it doesn't work. That leaves B, which makes sense. Potential energy to mechanical energy to electrical energy.
