vivado [14]

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:

$Percentage=\frac{X}{N}\times 100$

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:

$Percentage=\frac{181.3}{4096}\times 100=4.43\%$

Thus, the percentage of of the total energy production was generated by wind machines is 4.43%.

Williams uses his small motorboat to go 5 miles upstream to his favorite fishing spot. Against the current, the trip takes 1/3 h

laiz [17]

Answer: the boat can travel 20 mph in still water.

Step-by-step explanation:

Let x represent the speed of the boat in still water.

Let y represent the speed of the current.

Distance = speed × time

Williams uses his small motorboat to go 5 miles upstream to his favorite fishing spot. Against the current, the trip takes 1/3 hour. The total speed would be (x - y) mph. The distance covered upstream is

5 = 1/3(x - y)

Cross multiplying by 3, it becomes

15 = x - y - - - - - - - - - - - -1

With the current the trip takes 1/5 hour. The total speed would be

(x + y) mph. The distance covered downstream is

5 = 1/5(x + y)

Cross multiplying by 5, it becomes

25 = x + y - - - - - - - - - - - -2

Adding equation 1 to equation 2, it becomes

40 = 2x

x = 20/2 = 20

Substituting x = 20 into equation 1, it becomes

15 = 20 - y

y = 20 - 15

y = 5
