Answer:

about 10,652 balls

Step-by-step explanation:

The length of the court is 94 ft × 12 in/ft = 1128 in. That is 1128/8.5 ≈ 132.7 times the diameter of a ball.

The width of the court is 50 ft × 12 in/ft = 600 in. That is 600/8.5 ≈ 70.6 times the diameter of a ball.

When the balls are hexagonally packed, their row spacing is only (√3)/2 ≈ 0.866 times the ball diameter, so by cutting out one ball per row on alternate rows, about 15% more rows can be put in place. That is, there can be 81 rows of balls, alternating between 132 and 131 balls per row.

The number of balls that fit in that arrangement is ...

132×81 - 40 = 10,652

___

Since there is some extra space beyond the last row, the balls can be "randomized" and a few more balls added, probably at least 2 or 3.

Nancy shot a 16 on 4 holes of golf. At this rate, what can she expect her score to be if she plays 18 hole? Round to the nearest

Nataliya [291]

Answer:

108.

Step-by-step explanation:

"At this rate, ..." means we're to assume Nancy's score is proportional to the number of holes:

score/18 = 24/4

Multiplying by 18, we get ...

score = 18(24/4) = 18(6) = 108

Nancy can expect a score of 108 on 18 holes.

(if this isn't right, tell me and I will make sure to recheck my work :).

In a research of investigating the effects of working in crowded versus uncrowded conditions on the job satisfaction of employees in a variety of work setting , working is a depending variable and crowding is an independent variable.

Given aim of the research is to investigate the effects of working in crowded conditions and uncrowded conditions.

We know that depending variable is a variable whose value is dependent on the other variable. Independent variable is a variable whose value does not dependent on the other variables.

In the given question working may be affected negatively in crowded environment means there will be less work in crowded environment and more work in uncrowded environment.

Hence the depending variable in research is working.
