Lesson 2 Skills Practice Answer Key
In this answer key for Lesson 2 skills practice, we will go over the solutions to the different exercises. Let’s begin!
Exercise 1:
- Step 1: First, we evaluate the expression inside the parentheses: (1 + 2) × 3. This simplifies to 3 × 3, which is equal to 9.
- Step 2: Next, we evaluate the expression inside the brackets: [9 – 4]. This simplifies to 5.
- Step 3: Finally, we evaluate the expression inside the braces: {5 + 6}. This simplifies to 11.
- Step 4: Now, we solve the outermost operation, which is multiplication: 9 × 5. This equals 45.
Exercise 2:
In this exercise, we are given a table with the number of pizzas sold by three different pizza delivery companies. We are asked to calculate the total number of pizzas sold.
| Company | Number of Pizzas Sold |
|---|---|
| Pizza Co. A | 10 |
| Pizza Co. B | 15 |
| Pizza Co. C | 8 |
To find the total number of pizzas sold, we simply add up the number of pizzas sold by each company. The calculation is as follows:
Total = 10 + 15 + 8 = 33
This wraps up our answer key for Lesson 2 skills practice. Make sure to double-check your answers and reach out if you have any further questions. Keep up the good work!
Solution for Question 1
The first question in the skills practice requires determining the slope of a line given two points, (-1, 3) and (4, -2). To find the slope, we can use the formula:
slope = (change in y)/(change in x)
In this case, the change in y is -2 – 3 = -5, and the change in x is 4 – (-1) = 5. Plugging these values into the formula, we get:
slope = -5/5 = -1
Therefore, the slope of the line passing through (-1, 3) and (4, -2) is -1.
Answer for Question 2
Question: How does the author describe the importance of communication skills in the workplace?
Answer: The author emphasizes the significance of communication skills in the workplace, stating that they are essential for success in any profession. Effective communication allows individuals to convey their ideas, thoughts, and instructions clearly and accurately, ensuring that tasks are completed efficiently and without any misunderstandings. Moreover, the author highlights that communication skills are vital for building strong relationships with colleagues, clients, and customers. Effective communication fosters collaboration, teamwork, and trust, which are crucial for achieving common goals and maintaining a positive work environment.
The author further explains that communication skills are not only important for interpersonal interactions but also for professional growth. Strong communication skills enable individuals to advocate for themselves, express their needs and opinions, and negotiate their ideas effectively. This empowers individuals to take on leadership roles, influence decision-making processes, and advance in their careers. The author also acknowledges that communication skills are indispensable in resolving conflicts and addressing issues in the workplace. Clear and empathetic communication promotes understanding, encourages open dialogue, and helps find mutually beneficial solutions.
In conclusion, the author underscores the importance of communication skills in the workplace, highlighting their impact on productivity, relationships, and personal growth. Developing and honing these skills can significantly contribute to professional success and create a positive and collaborative work environment.
Explanation for Question 3
The third question in the Lesson 2 skills practice asks about the number of significant figures in a given value. In order to determine the number of significant figures, it is important to understand what significant figures represent. Significant figures are the digits in a number that carry meaningful information. They are used to indicate the precision of a measurement or calculation.
In the specific question, the given value is 15.00. The significant figures in this value can be determined as follows:
- The first digit, 1, is non-zero, so it is significant.
- The second digit, 5, is also non-zero, so it is significant.
- The third and fourth digits, 0, are zero but they are between non-zero digits (1 and 5), so they are also significant.
Therefore, the value 15.00 has four significant figures. It is important to note that the zeros in this value are considered significant because they provide information about the precision of the measurement. Without these zeros, the value would be written as 15, which implies only two significant figures.
Answer Key for Question 4
In question 4, students were asked to solve a mathematical problem involving fractions. The problem stated that there were 8 pies to be divided among 12 people. The students were asked to find out how many pies each person would receive.
To solve this problem, students needed to divide the number of pies (8) by the number of people (12). The answer key reveals that each person would receive 2/3 of a pie. This means that they would not receive a whole pie, but rather a fraction of one.
The answer key also shows that if students wanted to convert the fraction into a decimal, each person would receive approximately 0.66667 of a pie. This decimal would represent a recurring decimal, meaning that the number 6 would continue to repeat after the decimal point.
It is important for students to understand how to solve problems involving fractions, as they often appear in math problems and real-world scenarios. By practicing and becoming familiar with fraction calculations, students can improve their problem-solving skills and numerical fluency.
Overall, the answer key for question 4 provides students with the correct solution to the given problem, helping them to check their work and verify their answers. It serves as a valuable tool for learning and understanding fractions in mathematics.
Solution for Question 5
Question 5 asks for the distance between two points on a coordinate plane. To find the distance between two points (x1, y1) and (x2, y2), we can use the distance formula. The distance formula is derived from the Pythagorean theorem and is given by:
d = √((x2 – x1)^2 + (y2 – y1)^2)
Let’s apply this formula to the given points. The first point is (-3, 2) and the second point is (4, -5). Plugging these values into the formula, we get:
d = √((4 – (-3))^2 + (-5 – 2)^2)
d = √((7)^2 + (-7)^2)
d = √(49 + 49)
d = √98
Therefore, the distance between the two points (-3, 2) and (4, -5) is √98 or approximately 9.899494936611665 units.
Let’s Check the Answer for Question 6
Question 6 in the Lesson 2 skills practice was about solving a math problem involving fractions. The problem stated that a pizza was divided into 8 equal slices, and a person ate 3 slices. The question asked how many thirds of the whole pizza the person ate.
The correct answer to this question is 3 thirds. Since the person ate 3 out of the 8 slices, and each slice represents one eighth of the whole pizza, we can calculate the answer as follows:
- Each slice represents 1/8 of the pizza.
- Since the person ate 3 slices, they consumed 3/8 of the pizza.
- When we simplify 3/8, we get 3 thirds, which is the final answer.
Therefore, the person ate 3 thirds of the whole pizza. It’s important to understand the concept of fractions and how they relate to parts and wholes in order to solve this type of problem.
