Answer:
After 6 days, 3 bottles will be left.
Step-by-step explanation:
Given that:
Number of bottles = 15
Number of bottles drank each day = 2
Let,
d be the number of days
y be the number of bottles left
y = 15 - 2d
Now,
We have to find the number of days when 3 bottles will be left.
Putting y=3
3 = 15 - 2d
2d = 15 - 3
2d = 12
Dividing both sides by 2

Hence,
After 6 days, 3 bottles will be left.
Answer:
1.41a
Step-by-step explanation:
Let ABC is a right triangle with equal legs AB =BC.
Hence, ∠B is 90° and CA is the hypotenuse.
Now, applying Pythagoras Theorem, we can write
CA² = AB² + BC²
Let us assume that each legs AB = BC = a.
Therefore, CA² = a² +a² = 2a²
⇒Hypotenuse or CA = a√2 = 1.41a { Round to the nearest tenth} (Answer)
