Question

1. An average human body at rest consumes 300ml of oxygen per minute. How many liters is that in a day? Express in real numbers and exponentially.
2. Suzie attends ABIO202Z. The syllabus states that the total number of points possible in the course is 600 and that 80% of points are needed for a B-. Suzie has finished the course with 460.5 points. What percent of points possible has she achieved? Will she get a B-? If she does not have a B-, how many points will she need to get a B-?

Answer 1

you said that an average human body at rest consumes 300 ml of oxygen per minute.

Then for an hour it was 18000 ml or 18 Liter ( 300 ml X 60 Minutes (1 Hour).

For a day it was 432000 ml or 432 Liter...,,, it was only if a person was at rest condition throughout the day.

If the person involves the range of consumption also differs based on the work done by the person, because the oxygen consumption rate of person during work is increased when compare with oxygen intake rate of a person at rest.

Next question..,

the total number of points for the course is 600.

the percentage required for getting b- is 80% (480 points)

suize finished the course with 460.5 points which percentage was 76.75%. (for calculating percentage = the present value (460.5) divided by the total value (600) and multiplied by 100)

so hence she does not get the B- and the required additional point she needs to get B- was 19.5.
