<h2>Right answer: There is enough oxygen available for people’s lungs to function normally.
</h2>
<u>Air pollution</u> is due to a mixture of solid particles and gases in the air. This is caused by various polluting factors, among which are carbon monoxide emissions from automobiles, nitrogen oxides, chemical compounds from factories, dust and ozone.
In this context, <u>the inhalation of these toxic components increases the chances of having health problems, even death. </u>However, when these conditions are improved by removing pollutants and taking actions to purify the air; the life quality of the people who breathe it improves as well.
Therefore, <u>there is enough oxygen available for people’s lungs to function normally.
</u>
Answer:
25 is the answer
Explanation:
Step by step solution for calculating 40 is 160 percent of what number
We already have our first value 40 and the second value 160. Let's assume the unknown value is Y which answer we will find out.
As we have all the required values we need, Now we can put them in a simple mathematical formula as below:
STEP 140 = 160% × Y
STEP 240 =
160
100
× Y
Multiplying both sides by 100 and dividing both sides of the equation by 160 we will arrive at:
STEP 3Y = 40 ×
100
160
STEP 4Y = 40 × 100 ÷ 160
STEP 5Y = 25
Finally, we have found the value of Y which is 25 and that is our answer.
You can easily calculate 40 is 160 percent of what number by using any regular calculator, simply enter 40 × 100 ÷ 160 and you will get your answer which is 25
