The minimum number of rows is 1: if A is sorted in descending order, every next students will arrive in a row where everyone is taller than him, and no new rows will be created.
For example, consider
A = [190, 175, 170, 165, 150]
The first students creates the first row.
The second student is 175cm tall. In the first row everyone is taller than him (there's only the 190cm student), so he'll stand in this row.
The third student, 170cm, will find the row filled by the students who are 190 and 175cm tall. So, everyone is taller than him and he'll stand in that row as well.
You keep going with the other students, and you'll see that no one will form a new row.
Answer:
sorry all I know is "C" is 30
Step-by-step explanation:
For the first one
x=-6
the second your answer is 2.92 hours
Answer:
The y, in the equation, represents the total distance, in feet, from an ant t minutes after starting out from a location near its home. The 6 represents the the distance of the location where the ant starts traveling. The 3 represents the amount of feet covered in one minute. That's why when you increase the minute by one (experiment!!), the distance away from home increases by three, and that means that the ant is traveling at 3 ft/minute. (lol crazy)
3 = the ant's speed in ft/minute
