ONLINE MATHEMATICS PLATFORM: https://www.thyagoaraujo.com Solved questions from previous ENEM exams 01) (ENEM-2013) In the United States, the most widely used unit of measurement for volume in soda cans is the fluid ounce (floz), which is equivalent to approximately 2.95 centiliters (cL). It is known that the centiliter is one hundredth of a liter and that the can of soda usually sold in Brazil has a capacity of 355 mL. Thus, the measurement of the volume of a 355 mL soda can, in fluid ounces (floz), is closest to a) 0.83 b) 1.20 c) 12.03 d) 104.73 e) 120.34 02) (ENEM-2018) A map is a reduced and simplified representation of a location. This reduction, which is made using a scale, maintains the proportion of the represented space in relation to the real space. A certain map has a scale of 1 : 58,000,000. Consider that, in this map, the straight line segment that connects the ship to the treasure mark measures 7.6 cm. The real measurement, in kilometers, of this straight line segment is a) 4,408. b) 7,632. c) 44,080. d) 76,316. ​​e) 440,800. 03) (ENEM-2017) In some Anglo-Saxon countries, the unit of volume used to indicate the contents of some containers is the British fluid ounce. The volume of a British fluid ounce corresponds to 28.4130625 ml. For the sake of simplification, consider a British fluid ounce corresponding to 28 ml. Under these conditions, the volume of a container with a capacity of 400 British fluid ounces, in cm³, is equal to a) 11,200. b) 1120. c) 112. d) 11.2. e) 1.12. 04) (ENEM-2015) At the request of a mechanic, a welder will have to join two bars of different metals. The weld used has a thickness of 18 millimeters, as illustrated in the figure. What is the length, in meters, of the resulting piece after welding? A) 2.0230 B) 2.2300 C) 2.5018 D) 2.5180 E) 2.6800 05) (ENEM-2011) It is known that the real distance, in a straight line, from a city A, located in the state of São Paulo, to a city B, located in the state of Alagoas, is equal to 2,000 km. A student, when analyzing a map, verified with his ruler that the distance between these two cities, A and B, was 8 cm. The data indicate that the map observed by the student is on a scale of a) 1:250. b) 1:2500. c) 1:25000. d) 1:250000. e) 1:25000000.
