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?

x + y < 30

y ≥ 12

Step-by-step explanation:

Here, we want to write inequalities

From the question, we are told that there are fewer than 30 cones

Mathematically, we have this as;

x + y < 30

Secondly, at least 12 ( a dozen) large cones are needed

When we talk of at least, we mean it can be greater than but not less than

So the inequality in this case since y represents the number of large cones will be;

y ≥ 12

0.85 or 85%

step-by-step explanation:

1) divide 23 by 27

2) round the decimal to the nearest 10

3) so your answer would be 0.85 or 85%

the car was traveling 40 mph before it started skidding. ( 2 points ) 17. was the driver were her brakes working at 75% efficiency or better? ( 2 points ) yes 29.
