Question

Neil arrives home first and sets the air conditioner at 75 degrees. When Sandy arrives, she lowers it by 10 degrees. What is the magnitude of this change in thermostat levels?

Answer 1

The magnitude of the change in thermostat levels is 10 degrees.

To understand why, let's break down the steps:

1. Neil sets the air conditioner at 75 degrees.

2. Sandy arrives and lowers it by 10 degrees.

So, the change in thermostat levels is the difference between the initial setting (75 degrees) and the new setting after Sandy lowers it (75 - 10 = 65 degrees). The magnitude of this change is simply the absolute value of the difference, which in this case is 10 degrees.

In summary, when Sandy lowers the thermostat by 10 degrees, the magnitude of the change in thermostat levels is 10 degrees.

Answer 2

10 degrees

Explanation:

1. Neil arrives home first and sets the air conditioner at 75 degrees.
2. Sandy arrives later and decides to lower the thermostat by 10 degrees.
3. To find the magnitude of the change in thermostat levels, subtract the new temperature from the initial temperature.

• Initial temperature: 75 degrees
• Change in temperature: -10 degrees (since Sandy lowers it by 10 degrees)
• New temperature: 75 degrees - 10 degrees = 65 degrees

The magnitude of the change in thermostat levels is 10 degrees, as the temperature decreased by 10 degrees from the initial setting of 75 degrees.
