Answer:
The percentage of of the total energy production was generated by wind machines is 4.43%.
Step-by-step explanation:
Percentage is the proportion of an item in the whole.
The formula is:
It is provided that the wind machines in a country generated 181.3 billion kWh of electricity.
And the nation's total electricity production that year was 4,096 billion kWh.
Compute the percentage of of the total energy production was generated by wind machines as follows:
Thus, the percentage of of the total energy production was generated by wind machines is 4.43%.
Answer: A
Step-by-step explanation:
In order to find constant of proportionality, you have to use the equation, x(?)=y
The ? being the number to plug in, which would be 1/4 in this case. 8 times 1/4 is equal to 2 and so on.
Answer:
Velocity of plane is 100 mi/hr along northeast direction
Step-by-step explanation:
From the question it is given that Initial velocity of plane is 150 mi/hr along east north direction and wind is blowing at 50 mi/hr along southwest direction
since the velocity of wind and plane is exactly opposite
⇒ relative velocity of plane with respect to wind is given by
where is the velocity of plane = 150mi/hr and = velocity of wind = 50 mi/hr
Therefore, = alond northwest direction
Therefore, velocity of plane is 100 mi/hr along northeast direction
Let the middle number = X
Smallest number = X-2
Largest number = X +2
Add together:
X + X-2 + X+2 = 114
3X = 114
Divide both sides by 3:
X = 114/3
X = 38
Smallest number = X-2 = 38 -2 = 36
