(ENEM-2020) A cell phone model offers the option of unlocking the screen using a pattern of touches as a password. The touches can be made freely in the 4 numbered regions of the screen, and the user can choose between 3, 4 or 5 touches in total. Which expression represents the total number of existing codes? a) 45 - 44 - 43 b) 45 + 44 + 43 c) 45 x 44 x 43 d) (4!)5 e) 45 03. (ENEM-20) Brazil's soybean exports totaled 4.129 million tons in July 2012, and registered an increase in relation to July 2011, although there was a decrease in relation to May 2012. Available at: www.noticiasagricolas.com.br. Accessed on: August 2. 2012.

(ENEM-2013/PPL) American mathematician Eduardo Kasner asked his son to name a very large number, which consisted of the digit 1 followed by 100 zeros. His son named the number googol. Later, the same mathematician created a number that he nicknamed googolplex, which consisted of 10 raised to the power of one googol. How many digits does a googolplex have? a) 100 b) 101 c) 10100 d) 10100 + 1 e) 101000 + 1 05. (ENEM-2020/PPL) If the turtle, the slug and the snail were to race each other, the slug would come in last place, the snail would come in second to last and the turtle would come in first. According to American biologist Branley Allan Branson, the “record” speed ever recorded in research by a slug is 16.5 centimeters per minute. Available at: http://mundoestranho.abril.com.br. Accessed on: July 6, 2015. For a report, having the record speeds of the turtle and the snail in meters per second, it is necessary to know the conversion factor of the slug's record speed to meters per second in order to make a comparison. Based on the information, the conversion factor for the slug's record speed to meters per second is a) 10-2 × 60−2 b) 10-2 × 60−1 c) 10-2 × 60 d) 10-3 × 60−1 e) 10-3 × 60 --- Follow us on social media: ► PLATFORM (Website): https://thyagoaraujo.com/cursos/ ► Instagram: / escoladenumeros ► Instagram: / professorthyagoaraujo ► Instagram: / prof.raissacosta ► Instagram: / danieloliveira_qui ► Instagram: / andrefisica ► Twitter: / escoladenumeros CONTACT EMAIL: [email protected] Here on the channel you will find several free video classes in Mathematics, Chemistry, Physics and Biology for elementary and high school.
