25. Answer is D. If you asked the first three three questions, you would likely get a similar response each time. But if you asked the last question, you could make a list of statistics from the answers you get. Sorry I can't really explain this part well.
26. you'll have to convert each side from centimeters to feet using the ratio given to you (2cm=3ft). See the picture I attached. Final answer is A, 972 ft2.
27. Set up an equation. Make x the smallest number. Since 40 is the sum of 4 consecutive odd numbers, each number is two more than the number before it. Represent each number in terms of x.
#1: x
#2: x+2
#3: x+4
#4: x+6
The sum of the four numbers is 40, so set them up as an addition problem on one side of the equation. Make the other side 40.
x+x+2+x+4+x+6=40
Combine the x's.
4x+2+4+6=40
Add the numbers.
4x+12=40
Isolate 4x by subtracting 12 from each side.
4x=28
Divide by 4 to get x by itself.
x=7
So 7 is the first odd number. Next odd is 9, after that 11, and lastly 13. You can check your answer:
7+9+11+13=40
The largest odd number is 13, so B is your final answer.
