Final answer:
Ray pours 1.925L of water into 7 glasses from a 6.2L pitcher. Substracting this from the initial volume in the pitcher, we find that there are 4.275L of water left.
Step-by-step explanation:
We begin by figuring out the total amount of water Ray pours into the glasses. Each glass holds 0.275L of water, and he pours water into 7 glasses. So, to find the total amount of water poured, we multiply the volume each glass holds by the number of glasses:
0.275L/glass × 7 glasses = 1.925L
Now, we need to figure out how much water is left in the pitcher. The pitcher initially hold 6.2L of water. We subtract the amount of water Ray poured into the glasses from the initial amount of water in the pitcher.
6.2L - 1.925L = 4.275L
So, there are 4.275L of water left in the pitcher after Ray pours water into the 7 glasses.
