Answer: 248mL
Step-by-step explanation:
Given:
Concentration of buffer solution Cs = 1.24%w/v of boric acid
Concentration of boric acid solution Cb = 5 % w/v boric acid
For 1 liter of buffer solution, the weight of boric acid needed is:
mb = 1 × 1.24 = 1.24 unit weight
mb = Cb × Vb .....1
Cb = concentration of boric acid solution.
Vb = volume of boric acid solution needed.
mb = weight of boric acid needed.
From equation 1.
Vb = mb/Cb
Vb = 1.24/5
Vb = 0.248L
Vb = 248mL
Answer:
The 3rd and 4th option
Explanation:
A function only works when the input (x) only has one output (y).
The first, second, and the last option has the input has two or more outputs.
Fun Fact:
It is okay for the outputs to have more then in input, but not okay for the input to have more then one output.
I hope this help and have a nice day :)

Answer: The answer is 
ounces.
Step-by-step explanation: Given in the question the weight of Jarrett's puppy at birth, one week old and 2 weeks old are as follows:
We can see that
So, the weight of the baby will make an arithmetic progression with first term 'a' and common difference 'd' as follows:
Thus, the weight of the puupy after 3 weeks will be
Answer:
Most likely answers are either 6 or 8.
Step-by-step explanation:
The sequence could be of all even numbers, so 2, 4, 6, 8, etc.
Or of all powers of 2, starting at 2, so 2, 4, 8, 16, etc.
Since there are an infinite number of sequences that fit the pattern, you just have to choose the most likely.
