After the consumption of an alcoholic beverage, the concentration of alcohol in the bloodstream (blood alcohol concentration, or bac) surges as the alcohol is absorbed, followed by a gradual decline as the alcohol is metabolized. the function c(t) = 1.35te−2.802t † models the average bac, measured in mg/ml, of a group of eight male subjects t hours after rapid consumption of 15 ml of ethanol (corresponding to one alcoholic drink). a. what is the maximum average bac during the first 3 hours? (round your answer to three decimal places.) mg/ml b. when does it occur? (round your answer to two decimal places.) h

the answer is 844

step-by-step explanation:

it is 844 because if you add 836.50 + 7.5 you will get 844

the solution is the point

step-by-step explanation:

we have

> equation a

> equation b

adds equation a and equation b

substitute the value of x in equation b to find the value of y

the solution is the point

ratios represent a pattern or relationship that can be scaled.

equivalent ratios are pairs of ratios that represent the same relationship between quantities, and can be generated by multiplying or dividing both quantities in the ratio by the same factor.

in this lesson, students will use double number lines and ratio reasoning to solve ratio problems. by partitioning double number lines into proportionate intervals, students will build an understanding of equivalent ratio relationships as those that are generated by multiplying or dividing two related quantities by the same number. this lesson will build upon students' prior understanding of multiplicative comparisons, number line reasoning and equivalent fractions (while highlighting the difference between equivalent fractions and equivalent ratios); and will build toward future work in this unit on building ratio tables, and work in future grades in proportionality, scaling, and expressing and graphing linear functions.
