On a given morning, the temperature was 71℉. The temperature dropped 5℉ and then rose 8℉. How much does the temperature need to rise or fall to return to the initial temperature of 71℉?
The temperature dropped 5℉ and then rose 8℉, so it changed by 5℉ - 8℉ = -3℉.
To return to the initial temperature of 71℉, the temperature needs to rise or fall 3℉. Answer: \boxed{3}.
THATS WRONG
Apologies for the incorrect response. Let's calculate it correctly:
The temperature dropped by 5℉ and then rose by 8℉. When we add these changes together, we have a net increase of 8℉ - 5℉ = 3℉.
Since we want to return to the initial temperature of 71℉, we need to reverse this net increase by decreasing the temperature by 3℉. Therefore, the temperature needs to fall by 3℉. Answer: \boxed{3}.
Determine which of these illustrates two quantities that combine to make 0.
To illustrate two quantities that combine to make 0, we are looking for a pair of numbers where one is the opposite of the other.
For example:
-2 + 2 = 0
10 + (-10) = 0
3/4 + (-3/4) = 0
So any pair of numbers where one is the opposite of the other will combine to make 0.
To calculate how much the temperature needs to rise or fall to return to the initial temperature of 71℉, we need to find the net change in temperature.
Given:
Initial temperature: 71℉
Temperature dropped: 5℉
Temperature rose: 8℉
To find the net change, we need to subtract the temperature dropped from the initial temperature, and then add the temperature rose.
Net change in temperature = Initial temperature - Temperature dropped + Temperature rose
Net change in temperature = 71℉ - 5℉ + 8℉
Net change in temperature = 74℉ - 5℉
Net change in temperature = 69℉
Therefore, the temperature needs to fall by 2℉ to return to the initial temperature of 71℉.
To find out how much the temperature needs to rise or fall to return to the initial temperature of 71℉, we can break down the problem step by step.
Step 1: Determine the initial temperature: The initial temperature is given as 71℉.
Step 2: Calculate the change in temperature: First, the temperature dropped by 5℉. Therefore, we subtract 5℉ from the initial temperature:
71℉ - 5℉ = 66℉
Next, the temperature rose by 8℉. Therefore, we add 8℉ to the current temperature:
66℉ + 8℉ = 74℉
Step 3: Calculate the temperature change needed to return to the initial temperature: Subtract the current temperature from the initial temperature:
71℉ - 74℉ = -3℉
The temperature needs to fall by 3℉ to return to the initial temperature of 71℉.
