Sample Questions and Answers from Lesson 7
Below are sample questions that might be found in a typical Lesson 7 homework assignment, along with their corresponding answers.
Mathematics Examples
Question 1: Simplify the expression \( 3(x + 4) - 5 \).
Answer:
1. Distribute the \(3\):
\( 3x + 12 - 5 \)
2. Combine like terms:
\( 3x + 7 \)
Thus, the simplified expression is \( 3x + 7 \).
Question 2: Calculate the area of a triangle with a base of 10 cm and a height of 5 cm.
Answer:
Area of a triangle formula:
\[ A = \frac{1}{2} \times \text{base} \times \text{height} \]
Substituting the values:
\[ A = \frac{1}{2} \times 10 \times 5 = 25 \, \text{cm}^2 \]
Science Examples
Question 1: What is the primary function of the mitochondria in a cell?
Answer:
The mitochondria are known as the powerhouse of the cell. Their primary function is to produce adenosine triphosphate (ATP) through cellular respiration, providing energy for various cellular processes.
Question 2: Describe the process of photosynthesis.
Answer:
Photosynthesis is the process by which green plants, algae, and some bacteria convert light energy into chemical energy. The general equation for photosynthesis is:
\[ 6CO_2 + 6H_2O + \text{light energy} \rightarrow C_6H_{12}O_6 + 6O_2 \]
This process takes place in the chloroplasts, where carbon dioxide and water are transformed into glucose and oxygen using sunlight.
Language Arts Examples
Question 1: Identify the theme of the story "The Tortoise and the Hare."
Answer:
The theme of "The Tortoise and the Hare" is that slow and steady wins the race. It teaches the lesson that consistency and perseverance can lead to success, even when faced with seemingly more talented competitors.
Question 2: Write a sentence using the word "benevolent."
Answer:
The benevolent woman dedicated her time to helping those in need, ensuring that everyone in her community felt cared for and supported.
