Answer:
the number of houses ≈ 8.25 million houses
Explanation:
Given that:
A typical house in the United States uses about 10,900 kWh,
1 TWh (terawatt-hour) =1×10^6 GWh (gigawatt-hour) =1×10^9kWh (kilowatt-hour)
The three Gorges Dam in China produces about 90TWh of electricity each year. If it was to to be built in the United states, the number of houses such a plant would be able to provide the electricity for in a year is given as:
Number of houses = Amount of electricity produced in a year / amount of electricity used by each house.
Number of houses = 90 TWh / 10,900 kWh = 90 × 10⁹ kWh / 10,900 kWh = 8256881
Therefore the number of houses ≈ 8.25 million houses
The
conclusion of V.O. Key, Jr., about the voting study literature or the electoral
behavior is that it gives a vivid impression of the variety and subtlety of
factors that enter into individual voting decisions. He, V.O. Key, Jr., also
discuss about the theories on how voters behave become important because
candidates and their advisers are aware of them, and act as if voters' behavior
conforms to the theories.
So use half the surface area formula: SA=2πr^2 and plug in what you already know
since you don't know the radius yet, solve for it using the circumference
C=2πr
514.96=3.14(2)r
82=r
SA=2π(82)^2
SA=6.28(6724)
SA=42,226.72
so your answer is 42,226.72 yards squared
Answer:
The outer layer of the star expands
Explanation:
Late in life, when the hydrogen fuel for nuclear fusion is exhausted, the core of the star tends to collapse. That process generates heat that pushes the outer layers of the star outward.
The outer layer of the star expands.
