An aeration process, which consists of introducing air into a liquid, occurs as follows: a pump B removes the liquid from a tank T1 and makes it pass through aerator A1, which increases the volume of the liquid by 15%, and then through aerator A2, gaining a further volume increase of 10%. In the end, it is stored in a tank T2, as shown in the figure. FIGURE REPRESENTING THE SCHEME OF TANKS, PUMP AND AERATORS Tanks T1 and T2 are right prisms with rectangular bases, where the base of T1 has length c and width L, and the base of T2 has length c/2 and width 2L. To complete the aeration process without spilling the liquid in T2, the person in charge must know the relationship between the height of the liquid column that has already left T1, denoted by X, and the height of the liquid column that has reached T2, denoted by y. Available at: www.dec.ufcg.edu.br. Accessed on: April 21, 2015. The equation that relates the height measurements y and x is given by A) y = 1.265x B) y = 1.250x C) y = 1.150x D) y = 1.125x E) y = x This is a question that involves knowledge of Ratio and Proportion, more precisely understanding the concept of Percentage. Understanding the logic means we don't need many calculations to obtain the solution. Explained clearly and simply, step by step. #collegeentranceexam #mathematics #physics #chemistry #uninorte #itpac #ufac #cesmac #unima #uncisal #ufal #afya #fametro #uea #ufam #uniniltonlins #integrado #unifap #uniages #unidompedro #unifg #ebmsp #fam #faculdadeages #pitagoras #fasa #ftc #estacio #fip #ufvsf #unime #uneb #uefs #uesc #uesb #cat #ufba #ufob #ufrb #ufsba #unifasc #intaunita #unichristus #estaciofmj #unifor #uece #ufca #ufc #urca #uniceub #uniceplac #scesunineuro #escs #ucb #unb #multivix #unesc #emescam #ufes #uvv #famp #unievangelica #unicerrado #unifimes #unifan #pucgo #unirv #ueg #ufg #undb #edufor #uniceuma #uema #ufma #uniatenas #unibh #unec #unifacig #unipam #uniptan #unifagoc #atenas #faseh #fcmmg #fcms #fatra #fame #fmti #faminas #fadip #univertiix #ufv #ics #pucmg #puccontagem #pucpoçosdecaldas #unifaminas #fipmoc #ult #uniube #uemgpassos #univas #unimontes #unifal #ufgf #ufla #ufgm #ufop #ufsj #ufu #uftm #ufvjm #ufvjmteofilootoni #unipac #unifenas #univalemg #uniderp #uems #ufgd #ufms #ufmstreslagoas #univag #univar #fapan #unic #unemat #uftm #facimpa #cesupa #fesar #famaz #uepa #ufpa #unipe #unifip #unifsm #unifacisafmc #famene #ufpb #ufcg #fameg #uninassau #unitpe #facape #fmo #fms #fap #fps #fits #unicap #upe #univasf #uninovafapi #fahespiesvap #uespi #ufpi #ufpparnaiba #fag #camporeal #uninga #integrado #ufpr #fempar #fpp #pucpr #univel #unicesumar #unidep #uel #uem #uepg #unicentro #unioeste #unila #ufprtoledo #ufpr #unipar #up #unifaa #unifoa #uniredentor #unifeso #emsm #fmc #unifase #fmmscbji #facunilagos #fcmtr #ucb #univassouras #uerj #unigranrio #unesa #estacio #unirio #ufrj #ufrjmacae #uff #unig #uva #facenern #uern #ufrn #ufersa #unp #fimca #unisl #facimed #unescrondonia #finca #unir #uerr #ufrr #univates #pucrsmedicina #ucpel #ucs #ufp #unisc #unisinos #uffs #ufcspa #ufpel #ufsm #unipampauruguaiana #ufrgs #furg #feevale #ufn #ulbra #unijui #urierechim #unidavi #estaciodejaraguadosul #uniarp #unochapeco #univille #unifebe #unc #unesc #unoesc #uniplac #unisul #univali #uffschapeco #ufscararangua #ufsc #furb #ufs #unit #ufbm #unifaccamp #unisalesiano #ceuclar #unifae #fai #uniara #unimax #unifaj #unifunec #unifev #uniseb #unilus #unifacef #unifipa #saocamilo #unifsp #fam #facisb #fsl #fcmscsp #humanitas #medicinaguaruja #fjm #famema #funepe #famerp #fmabc #faceres #ficsae #fmpfm #fasm #fslm #slmandic #slmlimeira #unifadra #fema #pucampinas #pucspsorocaba #unilago #uam #uampiracicaba #uamsaojosedoscampos #ub #unicid #unifran #unimar #umc #unaerp #unisa #uscssp #fmrpusp #fmspusp #uspbauru #unitau #unoestejau #unoeste #unicamp #unesp #ufscar #unifesp #unimes #uscssp #uscs #uninove #ufs #usjt #unirg #unitpac #fapac #itpac #unirg #unitins #uft #aman #ita #essa #especex #ime #eear #eam #cmrj #cmpa #cmb #cmbh #cmf #cmm #cms #cmr #cmcg #cmc #cmjf #cmbel #cmsm #cmsp #ccmpr #ccmg #ccmsp #avenues #colegiobiasdepriene #colegiosprivados #colegiograded #concept #colegiofariasbrito #colegioaridesacavalcante #stpaulsschool #stfranciscollege #stnicolas #redhouseinternationalschool #colegiomobile #escolasuiçabrasileira #americanschoolbrasilia #viscondedeportoseguro #colegiochristus #institutodombarreto #colegioobjetivointegrado #colegiobernoulli #colegioetapa #colegium #colegiofarroupilha #colegiorosario
