Answer:
5 days
Step-by-step explanation:
Sohan can do the whole thing in 10 days
he worked 5 days so he did half

so if they worked together they'd do it in half the time
i.e 5 days
Answer: B
Step-by-step explanation:
The second power basically means that you multiply the number by itself that many times depending on the power, and since it's 50^2, the answer is Caleb - 100 | Jenna - 2,500. (Tip: Just multiply 50 x 50)

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

<em>Additional comment</em>
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.
