I think that I love society as much as most, and am ready enough to fasten myself like a bloodsucker for the time to any full-blooded man that comes in my way. This passage is excerpted from the 1854 book Walden by Henry David Thoreau, which details Thoreau's experience living in a cabin alone for two years. Stumped? Check out these SAT reading tips. Questions 1-3 are based on the following passage. ![]() What is the measure of minor arc XY ?īecause the question wants arc length and gives you the measure of the central angle in radians, you can use the formula s = rθ to find the arc length: s = (8)( 5 ⁄ 16 π) = 40 ⁄ 16 π, which reduces to 5 ⁄ 2 π, which is (B). In the figure below, circle O has a radius of 8, and angle XOY measures 5 ⁄ 16 π radians. That means the answer is (B) by process of elimination. If you ballpark (C) and (D), putting 10 or 15 in the function will give you a number bigger than 100, and you're looking for 76, so (C) and (D) are too big. You can tell that f (4) will be between 22 and 54, so you can cross out (A). If f(x) = 2x 2 + 4 for all real numbers x, which of the following is equal to f(3) + f(5) ? That matches the information in the question, so (B) is correct. The sales for the regular gasoline would be 475($2.39) = $1,135.25. A total of 550 gallons were sold, so the station would have sold 550 - 75 = 475 gallons of regular gasoline. If 75 gallons of premium were sold, the station would make 75($2.79) = $209.25 for those sales. ![]() Label them as gallons of premium and start with the value in (B). When asked for a specific value, try Plugging In the Answers. If the gas station sold a total of 550 gallons of both types of gasoline in one day for a total of $1,344.50, how many gallons of premium gasoline were sold? A gas station sells regular gasoline for $2.39 per gallon and premium gasoline for $2.79 per gallon. You can use a calculator for questions 1–2.
