To compare the weekly water levels in the pond using inequality symbols, we first need to convert the entries into a consistent format.
Here's the information provided:
- Week 1: 1.4 cm
- Week 2: 1.5 cm (one and one-half is equal to 1.5)
- Week 3: -2.1 cm (not needed for this comparison but is part of the context)
Now, let's compare Week 1 and Week 2:
- Week 1: 1.4
- Week 2: 1.5
Since 1.4 is less than 1.5, we can express this relationship using an inequality symbol:
1.4 < 1.5
In terms of the context provided, we write:
- Week 1 < Week 2
So the correct inequality symbol to compare the water levels between Week 1 and Week 2 is "<".
