Answer:

36 pages /4 hours.

Step-by-step explanation:

In order to find how many pages aaila reads in one hour, we need to take the amount she read in 4 hours and divide it by 4.

This is because that will allow us to find, the amount she reads in one hour.

She read 36 pages in 4 hours.

Therefore, our expression is 36 pages /4 hours.

Create your own real-world example of a relation that is a function. Domain: The set of Range: The set of
ivanzaharov [21]

Answer:

C(t)=5000 -10t

Step-by-step explanation:

There are many examples in the real world of relationships that are functions.

For example, imagine a tank full of water with a capacity of 5000 liters, this tank has a small hole, by which 10 liters of water are lost every hour.

If we call C the amount of water in the tank as a function of time, then we can write the following equation for C:

C(t)=C_{0}-at\\

Where:

C (t): Amount of water in the tank as a function of time

C_{0}: Initial amount of water in the tank at time t = 0

a: amount of water lost per hour

t: time in hours

Then the equation is:

C(t)=5000 -10t

The graph of C (t) is a line of negative slope. This relation is a function since for each value of t there is a single value of C.

Its domain is the set of all positive real numbers t between [0,500]

Because the time count starts at t = 0 when the tank is full and ends at t = 500 when empty

Its Range is the set of all positive real numbers C between [0,5000] Because the amount of water in the tank can never be less than zero or greater than 5000Litres

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%.
