1. Which of the following could be represented by -8?
A . A drop of 8 meters
B. 8 t shirts
C. Sea level in 8 places of the world
D. 8°c above zero
To determine which option could be represented by -8, we need to understand how negative numbers are typically used and represented.
In mathematics, negative numbers are used to represent values that are less than zero. They are usually indicated by a minus sign (-) placed in front of the number.
Now let's evaluate each option:
A. A drop of 8 meters: In this scenario, a drop of 8 meters would typically be represented as -8 meters, indicating that the drop is 8 meters below a reference point (such as ground level). Therefore, option A could be represented by -8.
B. 8 t-shirts: T-shirt quantities are typically considered as whole numbers, and negative values are not commonly used in this context. Therefore, option B is an unlikely representation of -8.
C. Sea level in 8 places of the world: Sea level is defined as zero elevation, and negative values are commonly used to represent depths below sea level. However, in this scenario, the question states "Sea level in 8 places of the world," which suggests that the focus is on the same reference point rather than depths below sea level. Therefore, option C is an unlikely representation of -8.
D. 8°C above zero: Temperature is typically represented on a numerical scale without the use of negative values for positive temperatures. In this scenario, 8°C above zero would be simply represented as +8°C. Therefore, option D is an unlikely representation of -8.
Based on the analysis, the correct answer would be A. A drop of 8 meters could be represented by -8.
