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%.

alex41 [277]

Answer:

3ft

Step-by-step explanation:

We are given that

Height of lamp, h=12ft

Height of shadow, l=6ft

Height of shadow of hydrant, l'=1.5ft

Let height of hydrant=h'

We have to find the height of fire hydrant.

All right triangles are similar

When two triangles are similar then, the ratio of their corresponding sides are equal.

Using the property

\frac{h}{h'}=\frac{l}{l'}

\frac{12}{h'}=\frac{6}{1.5}

h'=\frac{12\times 1.5}{6}

h'=3ft

Hence, the height of fire hydrant=3 ft

Use graphing technology to find the range of the function f(x)=2^x<br> .
Zinaida [17]

Look at the graph, which y values can the graph hit?

Anything above zero would be the right answer, since there is an asymptote at y=0.

So the range would be y>0

Hope this helps.

頑張って!
