The number of students, n, is inversely proportional to the time, t days, required to complete a project. it takes 12 students 20 days to complete a project. a) find the constant proportionality

b) write an inverse proportion equation

c) find the number of days it would take for 15 students to complete the same project.

pls answer I need a quick responses. Thank you so much to the ones that take the time out of their day to give us the answers. It’s very appreciated and helpful.

Browning labs is testing a new growth inhibitor for a certain type of bacteria. the bacteria naturally grows exponentially each hour at a rate of 6.2%. the researchers know that the inhibitor will make the growth rate of the bacteria less than or equal to its natural growth rate. the sample currently contains 100 bacteria.the container holding the sample can hold only 300 bacteria, after which the sample will no longer grow. however, the researchers are increasing the size of the container at a constant rate allowing the container to hold 100 more bacteria each hour. they would like to determine the possible number of bacteria in the container over time.create a system of inequalities to model the situation above, and use it to determine how many of the solutions are viable.
