82 X 10-6 glm3of pollutants in the air. ... The weight of 1m3 of air is approximately 1.3 X 103g.Suppose that the volume of air inside of a building is 3 x 106 m3.
Answer:
4.58
Step-by-step explanation:
21 is not a perfect square, but lies between the perfect squares 16 and 25. Thus, √21 lies between √16 and √25, that is, between 4 and 5. Since 21 is closer to 25 than to 16, √21 is closer to 5 than to 4. A rough estimate of √21 would be 4.7.
√21 done on a calculator comes out to 4.58.
<h2><em>The last graph because the slope is 40.
</em></h2><h2><em>
</em></h2><h2><em>Slope equals rise over run
</em></h2><h2><em>
</em></h2><h2><em>Rise is 4/ Run is 1
</em></h2><h2><em>
</em></h2><h2><em>4/1=4
</em></h2><h2><em>
</em></h2><h2><em>Slope (rate of change)=4</em></h2><h2><u><em>C</em></u></h2>
The correct answer to this would be -3x+8
