if 3.8 billion gallons of water are used for domestic use per day , approximately how many gallons of water are used for irrigation per day

Answer: 1.629 billion gallons of water a day are used for Irrigation.Step-by-step explanation:Great question, it is always good to ask away and get rid of any doubts that you may be having.According to my research which can also be found on the USDA ERS website. The Domestic Use (indoor) amount of water accounts for 70% of the total water used per day. While the Irrigation Water (outdoor) used per day accounts for 30%. This being the case We can use the Rule of Three technique to solve for the amount of irrigation water used per day. This rule is attached in the picture below.3.8 billion   ⇒   0.70    x billion   ⇒   0.30[tex]\frac{3.8 * 0.30}{0.70} = x[/tex][tex]1.629billion = x[/tex] ... rounded to the nearest thousandthWe can see from the calculation above that approximately 1.629 billion gallons of water a day are used for Irrigation.I hope this answered your question.
