A and C i believe that’s correct
Answer:
1.54 [km²].
Step-by-step explanation:
1) the given scale is for linear functions, the given area of the lake is quadratic function. According to this
2) actual area = given area *50000 *50000;
3) the given area=0.000616 [m²],
the actual area=0.000616*50000*50000=1540000 [m²] or 1.54 [km²].
It depends on what is being referred to by "this."
The description of the activity is that 10 drops are added twice and two readings are taken. If you do *that* 4 times, then a total of 20*4 = 80 drops will have been added.
If the activity referred to by "this" is the pair of acts {add 10 drops, read the volume}, then four repetitions will have added 10*4 = 40 drops.
Probably the expected interpretation is that "this" is {add 10 drops, read}, so 40 drops is likely the expected answer.
