wyoming electric coop owns a steam-turbine power-generating plant. because wyoming is rich in coal deposits, the plant generates

its steam from coal. this, however, may result in emission that does not meet the environmental protection agency (epa) standards. epa regulations limit sulfur dioxide discharge to 2000 parts per million per ton of cual burned and smoke discharge from the plant stacks to 20 ib per hour. the coop receives two grades of pulverized coal, c1 and c2, for use in the steam plant. the two grades are usually mixed together before burning. for simplicity, it can be assumed that the amount of sulfur pollutant discharged (in parts per million) is a weighted average of the proportion of each grade used in the mixture. the following data is based on the consumption of 1 ton per hr of each of the two coal grades. sulfur discharge smoke discharge steam generated coal grade in parts per million in ih per hour in ib per hour cl 1800 2.1 12,000 c2 2100 3 9,000 (a) determine the optimal ratio for mixing the two coal grades. (b) determine the effect of relaxing the smoke discharge limit by 1 ib on the amount of generated steam ner hour.

Is the length of the hypotenuse of a right triangle with legs that mea-
icang [17]
Answer:
Irrational Number

Step-by-step explanation:
So, since it's a right triangle, you can use Pythagorean Theorem to calculate the measure of the hypotenuse.

Pythagorean Theorem says the hypotenuse squared = the sum of the sides squared.

5² + 6² = 25 + 36 = 61

And the square root of 61 is 7.8102496.... and the decimal continues in no distinguishable pattern. Therefore, the length of the hypotenuse is an irrational number.
