vagabundo [1.1K]

Answer:

The value is U  =1.3908 *10^{11} \  kg

Explanation:

From the question we are told that

mass of carbon dioxide produced by one gallon of gasoline is m  =  9.50 \  kg

The number of cars is N =  40 \  million =  40 *10^{6} \  cars

The distance covered by each car is d =  7930 \ mi

The rate is R  =  23.6 \  mi/ gallon

Generally the amount of gasoline used by one car is mathematically represented as

G  =  \frac{d}{R}

=> G  =  \frac{7930}{23.6}

=> G  =   366 \  gallons

Generally the amount of gasoline used by N cars is

H  =  N  *  G

=> H  =  40*10^{6}  *  366

=> H  = 1.464*10^{10} \  gallons

Generally the annual production of carbon dioxide is mathematically represented as

U  =  m *  H

=> U  =9.50 *   1.464*10^{10}

=> U  =1.3908 *10^{11} \  kg
