sue picks up a cereal box and read that one serving provides 15 percent of the dv for total carbohydrate. what does this dv value tell us about the cereal?

It tells us that one serving of the cereal will give the consumer 15 percent of the total carbohydrate required per day for optimum body functioning according to experts.

Explanation:

The DV, otherwise known as daily value is the term used to describe the amount of a specific nutrient in a single serving of a particular food.

It is an indication of the amount of a particular nutrient present in one serving of a packaged food relative to the total amount of that nutrient required per day in humans or other animals.

Hence if one serving of a particular food provides 15% of the DV for carbohydrate, it means that a serving of such food per day will supply the person consumed it with 15% of the total carbohydrate recommended per day.

a = p(1 + rt) . . account balance after time t at rate r starting with principal p

3000 = 2500(1 + 0.0202t) . . filling in the given numbers

1.2 = 1 + 0.0202t . . divide by 2500

0.2 = 0.0202t . . . subtract 1

0.2/0.0202 = t ≈ 9.901

it will take about 9.9 years for the account balance to reach $3000.

when atoms of different types of elements join together, they make molecules called compounds. water consists of compound molecules made up of 2 hydrogen atoms and 1 oxygen atom. this is why it's called h2o. water will always have 2 times the number of hydrogen atoms as oxygen atoms.
