 A. Nikita Khrushchev B. Joseph Stalin C. Vyacheslav Molotov D. Vladimir Ilyich Lenin Stalin was General Secretary of the Communist Party of the Soviet Union's Central Committee from 1922 until his death in 1953. He created this title after consolidating power. 
 A. 4% B. 75% C. 300% D. 400% Volume of 4 cm cube = 64 cc. When it is cut into 1 cm cube, the volume of each of the cubes = 1cc Hence, there will be 64 such cubes. Surface area of small cubes = 6 (12) = 6 sq cm. Therefore, the surface area of 64 such cubes = 64 * 6 = 384 sq cm. The surface area of the large cube = 6(42) = 6*16 = 96. % increase = (384  96)/96 = 300% 
 A. x² + y² = 25 B. (x1)² + (y+3)² = 25 C. (x1)² + (y3)² = 25 D. (x+1)² + (y  3)² = 25 The formula is (xh)² + (yk)² = r² Be careful. The center coordinates are always subtracted from x and y. When you subtract a 3 it becomes a +3. 
 A. 1000 B. 1040 C. 1600 D. 1800 Total for 5 planes: 1200 x 5 = 6000 Total for 3 planes: 800 x 3 = 2400 6000  2400 = 3600 left as total for two planes 3600/2 = 1800 
 A. x = 4 B. x =  4 C. y = 6 D. y = 6 You know a point and the slope. The pointslope method of writing the equation of a line can be used. The equation is yy1 = m(xx1) where m is the slope and (x1,y1) is a point on the line. Substitution gives: y6=0(x4). This yields: y6=0. And finally we get: y=6. 
 A. 80 B. 82 C. 87 D. 92 This problem appears to have to many options. When you encounter similar problems, focus on the equation and find the largest multiplier….in this case the 5. It becomes your "determiner" in that it will open the doors with limitations it imposes. Here x can only be 1,2,3,4,5,or 6 because 5x7 = 35. Just quickly work through your options. 5(1) + 27 = 32 5(2) + 22 = 32 5(3) + 17 = 32 5(4) + 12 = 32 5(5) + 7 = 32
5(6) + 2 = 32 27 + 22 + 17 + 12 + 7 + 2 = 87 
 A. 30 P
B. 40P
C. 50 P
D. 60P
1.5 feet represent the radius. The circumference is 2Pr. So we get the circumference, multiply it by the number of revolutions per minute, multiply that product by 60 to get the hourly product, and divide this product (total number of feet) by 5,280 (the number of feet in a mile). 1,760 x 60 = 105,600 revolutions/hr 2(1.5)P = 3P (the circumference) 105,600 x 3P = 316,800P 316,800P/5280 = 60P. 
 A. 0.133 B. 0.2 C. 0.25 D. 0.5 We want to determine the probability of drawing a certain type of sock.

D. (p + 1)/15
p = q + 1/2 = 3r + 1 = 3(5s + 1/3) + 1. So, p = 15s + 2 or s = (p  2)/15. 
 A. 19 B. 39 C. 57 D. 59 The arithmetic mean of n numbers is their sum divided by n. So, (9 + 29 + y) / 3 = 19 or 38 + y = 19 x 3 = 57. Thus, y = 57  38 = 19.

 A. 235 B. 239 C. 243 D. 245 Let the smallest of the four consecutive odd integers be m. Then, m + (m + 2) + (m + 4) + (m + 6) = 968 or 4m + 12 = 968. Thus, m = 956 / 4 = 239. The four consecutive odd integers are 239, 241, 243 and 245. 
 A. 18 B. 36 C. 54 D. 72 Supplementary angles add to 180º. Represent the angles as 2x and 3x. 2x + 3x = 180 and 5x = 180 therefore x = 36. BE CAREFUL!! The question asked for the smaller angle (2x). 2x = 72.' 
 A. 20% B. 22.5% C. 27.5% D. 32% Threefourths is 75%. So, 75% of the fruits are peaches. Of the remaining 25%, onetenth are plums. So, 2.5% of the fruits are plums. Now, 100  75  2.5 = 22.5. So, 22.5% of the fruits are apples. Here, it is better to work in terms of percents rather than fractions. 
 A. 10 B. 12.5 C. 15 D. There is no median value. Arrange the values into ascending order: 5, 5, 10, 10, 10, 15, 15, 15, 20, 25 Since both 10 and 15 fall in the middle, the median is the average of these two values. (10+15)/2=12.5

 A. 3cd/40 B. 7cd/100 C. cd/750 D. 15cd/100 Manufacturing Cost = (d dolls/hour) (c cents/doll) = cd cents/hour = cd/100 $/hr. Now, 7 hours and 30 minutes = 7 1/2 hours = 15/2 hours. Total Manufacturing Cost = (cd/100 $/hr) (15/2 hr) = 15cd/200 $ = 3cd/40 $.

 A. 8 B. 11.7 C. 12 D. 13.6 Use the Pythagorean Theorem c²=a²+b² 
 A. I only. B. II only. C. I and II only. D. III only. Adding the equations gives 2x = 15 or x = 7.5. So, x > 5 (II is true). Substituting x = 7.5 gives z  y = 2.5. So, z > y (I is false). There are no further conditions on y. So, III is not necessarily true. 
 A. 10 B. 85 C. 105 D. 190 If you got this question wrong, you either misread it or forgot the correct order of operations. Solve what’s inside the parentheses first. Translating the information to an equation, we’d get the following: (1 + 2)(2 + 3)(3 + 4) = 1/2(20 + x) (3)(5)(7) = 1/2(20 + x) 105 = 1/2(20 + x) 210 = 20 + x 190 = x

 A. Grain. B. Maize. C. Indian wheat. D. Pakistani wheat. As the article states in lines 34, “this remarkably highyielding indigenous variety of wheat.” 
 A. 1.00 M B. 2.00 M C. 3.00 M D. 4.00 M Molarity Step 1: find the moles of solute using the formula: mass of solute (g) divided by formula mass of solute Step 2: divide the moles of solute by volume of solution in liters M / V. Or if you know the moles of solute, Molarity = moles of solute divided by volume of solution in liters . KF has a formula mass of 39 + 19 or 58 g/mole. Since 116 grams are given, 116g / 58g/mole = 2 moles of solute. To find the Molarity, take 2 moles of solute and divide by 1 L of solution. 2 moles / 1 L = 2.00 M solution 
 A. The I^{} ion is oxidized, and its oxidation number increases. B. The I^{} ion is oxidized, and its oxidation number decreases. C. The I^{} ion is reduced, and its oxidation number increases. D. The I^{} ion is reduced, and its oxidation number decreases. First, determine what happens to the I^{} ion. On the left side of the equation, the I ion is negatively charged. On the right side of the equation, the I ion is neutral. The I ion lost its negative charge by losing an electron. By definition oxidation occurs when electrons are lost .The ion becomes more positive (has a higher oxidation state). Pretend electrons are dollars. If you lose a dollar, you have less money. If you find a dollar or are given one, you no longer have a negative cash flow. You can also look at the half reaction of the I^{} ion: 2I^{}(aq) > I_{2}(s) + 2 e^{}: each I^{} ion loses an electron, increasing its oxidation number from 1 to 0. 
 A. The carbon atom in a carbonium ion has only 6 electrons. B. The stability of a carbonium ion is increased by charge dispersal. C. Carbonium ions can be classified as primary, secondary, or tertiary. D. A primary carbonium ion forms more easily than a tertiary carbonium ion. Carbonium ions are atoms that contain a carbon atom with only six electrons. They are classified as primary, secondary, and tertiary ions, as in the classification of the organic alcohols. Since the stability of a carbonium ion is greatly increased by charge dispersal, a tertiary carbonium ion, which has three alkyl groups, is more stable than a secondary carbonium ion, which has two alkyl groups. The more stable the carbonium ion, the more easily it is formed. 
 A. Ethane and ethanol. B. Methanol and methanal. C. 1propanol and 2propanol. D. Methanoic acid and ethanoic acid. By definition isomers have the same molecular formula but different structural formulas. Choice 3 compounds have the same molecular formula but the OH group is located on the first or second carbon atoms. The other choices do not have the same molecular formulas. 
 A. CH B. CH_{2} C. CH_{3} D. CH_{4} Step 1: change percent to grams. Step 2: find out how many moles you have of C and H by: 86 g / 12 g per mole of C = 7 moles of C; 14 / 1 g per mole H = 14 moles of H. Step 3: find the ratio of moles of C and H to each other: 14 / 7 is 2. In other words there are 2 H moles for every C mole or CH_{2}. This is the empirical formula. 
 A. Saponification. B. Neutralization. C. Polymerization. D. Oxidationreduction. When certain metals combine with oxygen in the air, a metallic oxide results. Iron oxide is commonly called rust. Other metals such as copper also oxidize. (The Statue of Liberty in NY Harbor was not always green). The term oxidationreduction is used to describe the additionremoval of oxygen. Oxidation is the process by which a substance loses one or more electrons. 
 A. 1 mOsm. B. 2 mOsm. C. 3 mOsm. D. 4 mOsm. The total number of particles in a solution affects osmotic pressure. If we assume complete dissociation, 1 mole of sodium chloride is composed of 2 mOsm of total particles (ie., Na+ and Cl). 
 A. It permits the migration of ions. B. It prevents the migration of electrons. C. It permits the two solutions to mix completely. D. It prevents the reaction from occurring spontaneously. In oxidationreduction reactions, ions need
