Question

According to the United States Department of Agriculture (USDA), Texas had 4 , 015 , 000 beef cows in 2013 . If one cow produces approximately 205 g of methane ( CH 4 ) per day, how much methane was produced by the beef cows in Texas in 2013 ?

Answer 1

Answer:

3.00 × 10¹¹ g

Explanation:

According to the United States Department of Agriculture (USDA), Texas had 4,015,000 beef cows in 2013. One beef cow produces 205 grams of methane per day. The methane produced by the beef cows in Texas per day is:

$4,015,000Cow \times \frac{205gCH_4}{cow \times day} = \frac{8.23 \times 10^{8}gCH_4}{day}$

Each year has 365 days. The methane produced by the beef cows in Texas per year is:

$\frac{8.23 \times 10^{8}gCH_4}{day} \times \frac{365day}{1y} = 3.00 \times 10^{11}gCH_4$
