A coach needs both small and large cones to set up an obstacle course. The coach knows that there are fewer than 30 cones in the storage room. The coach needs at least a dozen large cones. Let x represent the number of small cones and y represent the number of large cones. Which inequalities model the situation? Select each correct answer. y>12 x+y≤30 x+y<30 x>0 y≥12

80 the answer is 80

step-by-step explanation:

the answer i believe is 27 units.

step-by-step explanation:

the height of the surface increases from the center out to the sides of the road.

step-by-step explanation:

as we move out we move away from the x-axis.

and as mentioned in the problem statement that height of a road increases when we move away from the center x.

hence proved that 3rd option

the height of the surface increases from the center out to the sides of the road.

is the correct option.
