Answer:
8 laps
Step-by-step explanation:
You can simply add up the number of laps:
(1st student laps) + (2nd student laps) +(3rd student laps) +(4th student laps)
= 2 laps + 2 laps + 2 laps + 2 laps
= 8 laps . . . . total for the 4 students
__
Many people find it tedious to add the same number over and over, so they make use of the invention of multiplication. If you want to add 4 twos, you can simply multiply 4 times 2 to get the result.
total laps = (laps/student) × (number of students)
= (2 laps/student) × (4 students) = 8 laps

May people look at this and say "word problem!" and then turn off their brain and go into a state of shock.
It is more productive to read the words, and use your imagination to visualize the scenario and what the question is asking. If you imagine 4 team members standing at the starting line and anticipating running 2 laps (each), the total number of laps should be so obvious that you don't even have to think about how you arrived at the solution.

<span>If Marta's handler uses a graph to track the number of gallons of formula y the calf drinks in x hours then the relationship between x and y is linear and it is proportional. This is because the formula enables the calf to drink more and grow more.</span>
Answer:
because the smaller potato cube has a smaller volume to area ratio that means smaller absorption time.
Step-by-step explanation:
there are 2 things to consider:
1°) if the iodine enters at constant rate to the cube, the time required to completely absorb all the iodine is proportional to the mass of the potato cube ( more mass that is required to absorb, means more iodine should enter the cube at same rate and therefore more time) . also, the mass of the potato is proportional to the volume of it (assuming constant density)
2°) if we consider 2 potatoes with same mass, the time required is inversely proportional to the area of contact with the solution of iodine ( more area means more iodine is able to enter per mm2 of potato's surface with the same mass and consequently less time)
therefore, the time is proportional to the ratio of volume and area of the cube. Since the smaller cube has a smaller ratio, takes less time to be completely purple
