The square (call it ) has one vertex at the origin (0, 0, 0) and one edge on the y-axis, which tells us another vertex is (0, 3, 0). The normal vector to the plane is , which is enough information to figure out the equation of the plane containing :
We can parameterize this surface by
for and . Then the flux of , assumed to be
,
is
20*3=60

Correct answer, but terrible deal.
Answer:
754
Step-by-step explanation:
If the number in the one's place is 5 or greater, the number is rounded up to the next ten. If the number is less than 5, the number gets rounded down.
754 is the answer because it rounds down to 750 as it is, but if 1 was added to it, it'd be 755 which would round up to 760.
