This question seems like its too easy so i might have got it wrong.. but would't you just subtract 20 and 10 from 800 to get 770?

So first you add both gym and chess members then you minus to tht total amount of students: chess+gym=10+20=30   total students= 800 since the question asks how many people did not participate in either gym or chess so u minus: 800- 30 = 770 
so the answer will be 770 did not participate in both gym and chess

What is an advantage of using models to represent the carbon cycle?
andreev551 [17]

An advantage of using models to represent the carbon cycle is: B. show a complete and detailed account of every event in the cycle.

A carbon cycle refers to the series of biogeochemical processes through which carbon atoms or carbon compounds are interconverted and used by living organisms within an environment, especially by transporting carbon from the atmosphere to planet Earth and then back to the atmosphere.

Basically, there are four (4) main processes that are associated with carbon cycle and these include:

  • Respiration.
  • Consumption.
  • Combustion such as burning of fossil fuels.
  • Rock formation.

A model can be used to graphically illustrate or simulate the all of the activities (events) that are taking place within the carbon cycle.

Hence, an advantage of using models to represent the carbon cycle is that it would illustrate (show) a complete and detailed account of every event in the cycle.

What is energy efficiency? Explain why we can think of energy efficiency as an energy resource. What percentage of the energy us
LiRa [457]

Answer:

Energy efficiency is a determination of the amount of work one can obtain from each energy unit used. Improving energy efficiency signifies the usage of less energy to offer a similar amount of work in the forms of heat, light, transportation, and other benefits. This constitutes a largely untapped source of energy, which is clean, abundant, easily available, and cheap.  

About 84 percent of all the commercial energy utilized in the United States does not generate useful work. Approximately 41 percent of this energy generally ends up as low-quality waste heat in the environment due to deprivation of energy eminence levied by the 2nd law of thermodynamics. The remaining 43 percent is wasted needlessly, majorly because of the inefficacy of industrial motors, light bulbs, power plants, and motor vehicles.  

The four broadly used devices that waste energy are incandescent light bulb, a motor vehicle with an internal combustion engine, a coal-fired power plant, and a nuclear power plant. The prime advantages of reducing energy wastes are:

1. Reduces oil imports and betters energy security.  

2. Prolongs supplies of fossil fuels.  

3. Reduced pollution and environment degradation.  

4. Very high energy yield and low cost.  

The three prime reasons that energy efficiency has been neglected are:  

1. Energy stays artificially cheap (subsidies for fossil fuel and mining companies).  

2. Few large and long-enduring incentives for energy efficiency.  

3. Prices do not comprise cost of health and environmental influences.
