The blood alcohol concentration (BAC) of a person who has been drinking is given by the following expression. Number of ounce % alcohol x 0.075 divide body weight in pounds minus hour of drinking x 0.015
In 4 hours a 220lb person has drunk 5 12 ounce beer (60z) each have 5.5% alcohol content find person Bac and round off to the nearest thousandths
Well, well, well, it seems like we have a thirsty friend here! Let's get down to the math and find out your BAC, shall we?
First, we need to calculate the total alcohol consumed. We have 5 beers, each with a volume of 12 ounces and an alcohol content of 5.5%, so we multiply:
5 beers x 12 ounces x 5.5% = 33 ounces of alcohol consumed.
Now, let's calculate the BAC using the formula you provided:
BAC = (33 ounces x 0.075) / (220 pounds - 4 hours x 0.015)
BAC = 2.475 / (220 - 0.06)
BAC = 2.475 / 219.94
BAC ≈ 0.0112
So, rounding off to the nearest thousandths, the person's BAC is approximately 0.011.
Remember, though, that this is just an estimation based on the formula. Alcohol affects people differently, so it's always a good idea to drink responsibly and never drink and drive. Stay safe, my friend!
To calculate the blood alcohol concentration (BAC), you need to follow these steps:
Step 1: Calculate the total amount of alcohol consumed.
Multiply the number of drinks by the alcohol content of each drink.
5 drinks * 12 ounces/drink * 5.5% alcohol content = 33 ounces of alcohol
Step 2: Calculate the weight of the person in grams.
Multiply the weight in pounds by 453.592 (conversion factor).
220 pounds * 453.592 = 99,791.84 grams
Step 3: Calculate the BAC.
Use the formula: (Total Alcohol in ounces * 0.075) / (Body weight in pounds * 0.015 - (Hours of drinking * 0.015))
(33 * 0.075) / (220 * 0.015 - (4 * 0.015)) = 0.05775 / (3.3 - 0.06)
0.05775 / 3.24 ≈ 0.0178
Step 4: Round off the BAC to the nearest thousandths.
BAC = 0.0178 (rounded to the nearest thousandths)
Therefore, the person's BAC after 4 hours of drinking is approximately 0.018.
To calculate the blood alcohol concentration (BAC) of a person, you need to use the given formula and substitute the given values into it. The formula you provided is:
BAC = (Number of ounce % alcohol x 0.075) / (Body weight in pounds - (Hour of drinking x 0.015))
Let's break down the steps to find the BAC:
Step 1: Calculate the total alcohol consumed in ounces.
Given that the person has drunk 5 beers of 12 ounces each, the total alcohol consumed in ounces is:
Total alcohol consumed = 5 beers x 12 ounces/beer = 60 ounces
Step 2: Calculate the alcohol content in percentage.
Given that each beer has 5.5% alcohol content, the alcohol content of all the beers consumed is:
Total alcohol content = Total alcohol consumed x alcohol content per beer = 60 ounces x 5.5% = 3.3 ounces
Step 3: Calculate the BAC using the formula.
Given that the person weighs 220 pounds and has been drinking for 4 hours, we can substitute these values into the formula:
BAC = (3.3 ounces x 0.075) / (220 pounds - (4 hours x 0.015))
Step 4: Calculate the BAC and round off to the nearest thousandths.
BAC = (0.2475) / (220 - 0.06)
BAC = 0.2475 / 219.94
BAC ≈ 0.001125
Rounded to three decimal places, the person's blood alcohol concentration (BAC) is approximately 0.001.
