Average speed = total distances / total time
3115.8 / 7.2 = 432.75 mi/h
Answer:
B
Step-by-step explanation:
y-intercept is positive 5 so that eliminates answer choices A and C
to decide between B and D, select a point in the solution area; for example, (0, 0). Plug these values into B and D and see which one it is true for
B) 0 ≥ -3(0)-5
Is 0 ≥ -5 Yes
D) 0 ≤ -3(0)-5
Is 0 ≤ -5 No
Answer:
Line d
Step-by-step explanation:
Line A could not be parallel to line C and neither cold line B because they would cross at some point. Line D is parallel because it would not cross line C at any point. Plane Q oculd not be parallel to line C because it is a plane and it is perpendicular to line C.
B = no. of buses
v = no. of vans
b + v less than or equal to 8 ( there are only 8 drivers, but don't have to use them all)
51b + 8v greater than or equal to 193 (the number of seats must be at least 193 but there can be spares)
So these are the inequalities to solve. I did start doing a linear programming graph but the second inequality is horrible so I hope you don't need to actually solve them.
