You are drawing a net that shows a rectangular prism with an area of 52 square feet. If two of the rectangles in the net are 4 ft.×3 ft., what is the value of the third measurement you need to know to have an area of 52 square feet?
We can start by finding the total area of all the rectangles in the net. Since two of the rectangles are 4 ft.×3 ft., their total area is:
2 × 4 ft. × 3 ft. = 24 square feet
Let's denote the third rectangle's dimensions as x ft. × y ft. Then, we know that the total area of the net is 52 square feet, so we can set up an equation:
24 + x y = 52
Solving for xy, we get:
xy = 52 - 24 = 28
Therefore, to find the value of the third measurement we need to know, we can solve for either x or y. Let's solve for x:
x y = 28
x = 28 / y
Now we just need to substitute this expression for x into one of the rectangle dimensions:
x ft. × 3 ft. = 4 ft. × 3 ft.
Substituting x = 28 / y, we get:
(28 / y) ft. × 3 ft. = 4 ft. × 3 ft.
Multiplying both sides by y/3, we get:
28 ft. = (4 ft. × y)
Dividing both sides by 4 ft., we get:
y = 7 ft.
Therefore, the dimensions of the third rectangle in the net are 28/7 ft. × 7 ft., or simplified, 4 ft. × 7 ft.
To determine the correct answer between option a and b, we need to analyze each option and consider the purpose and benefits of paying attention to radio and television commercials.
a. The most accurate information on competing products: While radio and television commercials can provide information on products, it is important to note that these commercials are primarily marketing tools designed to promote and sell products. While they may contain accurate information, they might also be biased or present a one-sided view of the product. Therefore, relying solely on commercials may not always provide the most accurate information about competing products.
b. Practice in careful listening: Paying attention to radio and television commercials can indeed provide practice in careful listening. Commercials are usually short and concise, requiring listeners to pay attention and process the information quickly. By actively listening to commercials, individuals can improve their listening skills, focus, and ability to comprehend information in a limited timeframe.
Based on the analysis, the correct answer is:
b. Practice in careful listening.
Paying attention to radio and television commercials can be considered a valuable method to develop and enhance one's listening skills, rather than purely relying on them for the most accurate information on competing products.
