What is
-7 + 8 ?
-7 + 8 ?
The initial temperature at 7:00 am was -7 degrees Celsius.
The temperature rose by 8 degrees Celsius during the morning.
Therefore, to find the temperature at noon, we can add the rise in temperature to the initial temperature:
-7 degrees Celsius + 8 degrees Celsius = +1 degrees Celsius
So, the temperature at noon was +1 degrees Celsius.
First, let's convert -7 degrees Celsius to Fahrenheit. We can use the conversion formula: F = (C * 9/5) + 32.
F = (-7 * 9/5) + 32
F = (-63/5) + 32
F = -12.6 + 32
F = 19.4 degrees Fahrenheit
Now, let's calculate the temperature at noon:
Starting temperature (in Fahrenheit) = 19.4 degrees Fahrenheit
Increase in temperature = 8 degrees Celsius
To convert the increase in temperature from Celsius to Fahrenheit, we can use the same conversion formula:
C = (F - 32) * 5/9
Let's substitute the values:
8 = (F - 32) * 5/9
Multiplying both sides by 9:
72 = (F - 32) * 5
Dividing both sides by 5:
14.4 = F - 32
Adding 32 to both sides:
14.4 + 32 = F
46.4 = F
Therefore, the temperature at noon is 46.4 degrees Fahrenheit.
