Selma's class is making care packages to give to victims of a natural disaster. Selma packs one box in 5 minutes and has already packed 12 boxes. Her friend Trudy packs one box in 7 minutes and has already packed 18 boxes. How many more minutes does each need to work in order to have backed the same number of boxes?

Answers

Every 35 minutes Selma packs 7 boxes, while Trudy packs 5 boxes.

Thus every 35 minutes Selma decreases the difference between them in 2 boxes.

Since the original difference was 6 boxes, Selma needs 3 times 35 minutes, or 105 minutes, in all, to catch Trudy.

Answer- 105 minutes, or 1 hour and 45 minutes.

John is a new employee at International Widget. Having studied human relations, he's eager to understand the supervisory style employed by his immediate supervisor. Which of the following is not especially important to John's insight?a. His supervisor's flexibility on work guidelines
b. Whether his supervisor enjoys particular sports or hobbies
c. The extent to which he (John) is expected to work independently
d. Whether his supervisor is more concerned about short-term or long-term work goals

Answers

The correct option is B. In order for John to understand the supervisory style employed by his immediate supervisor, he does not needs to know the type of sport that his supervisor enjoys, for that particular information is not related to how the supervisor expects John to handle office work. The other statements are John's job related and they are good means of getting insight into the supervisory style of a supervisor.

Write a compound inequality that represents the evelation range for each type of plant life

Answers

Let E=elevation range
Low elevation=1700≤E≤2500
Mid elevation= 2500≤E≤4000
Sulbarine=4000≤E≤6500
Alpine=6500≤E≤14,410

Final answer:

To represent the elevation range for each type of plant life, write a compound inequality for each type using the minimum and maximum elevations.

Explanation:

To write a compound inequality to represent the elevation range for each type of plant life, we need to consider the minimum and maximum elevations for each type. Let's say Type A has a minimum elevation of 1000 ft and a maximum elevation of 3000 ft, and Type B has a minimum elevation of 2000 ft and a maximum elevation of 4000 ft. We can represent the elevation range for Type A as: 1000 ≤ x ≤ 3000, and for Type B as: 2000 ≤ x ≤ 4000.
