The graphs of the following equations are drawn: 1. y = 3x - 2 2. y = x^2 3. y = 1 - x^2 4. y = x + 6 3 and 4 An ore of lead contains 70 % of PbS. Calculate the mass of lead that can be extracted from 478k of the ore. (Ar: Pb = 207; S = 32) A - 28.98kg B - 41.4 kg C - 144.9 kg D - 289.8 kg E - 414.00kg Answer: 478 x 0.7 = 334.6 mass of PbS 334.6 / (207+32) = 1.4 = no. of moles of PbS 1.4 x 207 = 289.8 kg = mass of lead Therefore D is the answer. The energy in joules...

Angles that look the same can be assumed to be the same, even if you can't prove it, since there is no other way to solve it. For example, ACD can be assumed to be 25° -ANSWER You are asked to solve for DBC and are stuck. What might be a reasonable assumption to help solve it? Just from eyeballing it, the answer is greater than 180, which is a straight line. It also seems less than 270, which would leave only a 90° angle. 252° is a reasonable answer. -ANSWER What answer seems most reaso...

Praxis- Mathematics Questions and Answers 100% Pass In the proceeding figure, P and T are points on like k, and points Q, R and S are points on line l. Lines k and l are parallel. What is the measure of the angle TRS? Since angles PTR and TRS are alternate interior angles, they are congruent and they have the same angle measure. The equation: 5x + 10 + 110 = 8x+102 x=6. The measure of angle TRS is 8 x 6 + 102 = 150 degrees. The following table shows the distribution of 50 cookies sold in a sto...
