What’s the story?

Measuring Devices

Conversions 1 ml = .025 oz 1000 ml = 1 L 1 kg = 2.2 lbs

Abbreviations: ml = milliliter oz = ounce L =

literlbs = pounds

Conversion FormulaExample:Changing pounds (lbs) to kilograms (kg). Brittney weighs 100 pounds. How much

does she weigh in kilograms?

Conversion 1 kg = 2.2 lbs

100 lbs x 1 kg = 100 = 100 ÷2.2 = 45.5 kg 1 2.2 lbs 2.2

Measuring Alcohol in the BodyBlood Alcohol Concentration (BAC) : Mass per volume

of blood in the body (Eg: 0.08 g/L)

(150/body weight) x (% alcohol/50) x ounces consumed x 0.025 = BAC

150/126 x 5/50 x 12 x 0.025 = .0357 = .04

Suppose he weighs 250 lbs?

150/250 x 5/50 x 12 x 0.025 = .0225 = .02

Examples: Suppose a person weighing 126 lbs drinks a 12 oz beer with 5% alcohol, what is his BAC?

Liver MetabolismA 150-pound person with normal liver function

metabolizes about 7 to 14 grams of alcohol per hour. This is comparable to 8 to 12 ounces of beer or half of an alcoholic drink. Controlling the rate of consumption will give your liver time to metabolize the alcohol and limit your BAC. Once you stop drinking, your blood alcohol level decreases by about 1.5% per hour. You are legally intoxicated with a blood alcohol concentration of 0.08. Time is the only way to eliminate alcohol from your system, so cold showers and coffee will not sober you up. Trying to get someone who is drunk to feel and appear more alert can cause a false sense of sobriety and result in many problems.

Problems for Practice1. Ed has fallen into a stupor with a BAC

(blood alcohol concentration) of .21; after one hour what is his BAC if the liver removes 1.5% of alcohol per hour?

Answer:.21 x .015 = .00315

.21 - .00315 = 0.20685 Interpretation: Your liver does not remove alcohol from you system very quickly!

Problems for Practice Continued

2. A tourist consumed 5 liters of beer at dinner. If 1 can of beer is 12 ounces (oz), how many cans of beer did the tourist consume?

1 ml = .03 oz 1 L = 1000 ml

Answer: 5 x 1000 = 5000 5000 x .025 = 125oz125 12 = 10.4 beers!!!!

Similar Math Problems1. Danskos are on sale for 25% off. If they

are normally $120, how much do they cost now?

$120 x .75 = $90Or$120 x .25 = 30120 – 30 = $90

2. There are 500 ml of water in a Dasani water bottle. How many ounces is that?

500 ml x 0.025 oz = 12.5 oz. 1 ml

The distance between Eagle River and downtown Anchorage is 12 miles. If you are traveling 65 miles per hour, how long will it take you to make the trip? (NOTE: distance = rate x time or d = r x t)

12mi = 65mph x t12 ÷ 65 = t .1846 hr = t.1846 x 60 = 11min
