Aman who weighs approximately 140 pounds has two,12 ounce beers and one 1 1/2 oz. shots of liquor in one hour. what is his estimated bac?

His estimated BAC is 0.08

Step-by-step explanation:

To calculate the BAC (Blood Alcohol Content) we first find the amount of alcohol (in grams) of the drinks.  

In the US, a standard drink has 14 g of alcohol.  The man has 2 beers and 1 shot; this is 3 standard drinks:

3 × 14 = 42 g of alcohol.

Next we convert the weight in pounds to grams.   1 pound = 453.592 grams

We do this by multiplying by 454:

140 × 454 = 63560

Next we multiply by the gender constant.  For men, this is 0.68:

63560(0.68) = 43220.8

We divide the grams of alcohol by this number:

42 ÷ 43220.8 = 0.000972

Multiply this by 100:

0.000972(100) = 0.0972

This is the BAC right after drinking.  To account for the time that has passed, we multiply the number of hours by 0.015:

1 × 0.015 = 0.015

We subtract this from our immediate BAC:

0.0972 - 0.015 = 0.0822 ≈ 0.08

His estimated BAC is 0.08

step-by-step explanation:

not only in mathematics, scientific proof also are required in the other field of science. also maths proofs are of particular structure, containing steps and logics. so proving is like doing science, it is science. that's why it is important to prove. 

an inaccurate proof leads to errors, or stating results that are not accurate.  which wil mess the probelm up you dont want this
