Final Answer:
The sum of -4.7°F and 11.6°F is 6.8999999999999995°F.
Step-by-step explanation:
Sure, let's solve this step by step.
Step 1: Identify the numbers
We have two temperatures, -4.7°F and 11.6°F.
Step 2: Add the temperatures
Now, we are going to add these two temperatures together.
When you add a negative number and a positive number, you essentially subtract the absolute values (ignoring the signs) and use the sign of the number with the larger absolute value.
So here, we consider the absolute values |−4.7| and |11.6|.
|−4.7| = 4.7 and |11.6| = 11.6
It's clear that 11.6 has the larger absolute value and it’s a positive number.
So we subtract 4.7 (absolute value of -4.7) from 11.6.
Step 3: Subtract the numbers
11.6 - 4.7 = 6.9
Therefore, In a simpler form, it can be approximated as 6.9°F. The decimal discrepancy is typically due to the way computers handle floating-point arithmetic.
