Answer:
y of what do you have at least a picture?
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: You're correct
Step-by-step explanation:
All values on the dice are < 7, so 6/6 are less.
6/6 simplifies to 1, so that is also correct.
6/6 = 1 = 100%
0/6 is incorrect.
F because, if you take 270/450=.6 or 60% and that would be your p, and 60%/100=.6

Answer:
y=x+3
Step-by-step explanation:
The equation "y=x+3" cannot be written in the form y=kx because <u><em>the form </em></u><u><em>doesn't use addition</em></u><u><em> as a basic operation.</em></u> Let's try verifying the choices:
y=x is possible<em> </em>if the value of k is 1, provided that both y and x are of the same value.
y/2=x is possible because y=2x, provided that 2 is the value of k.
y=-1/10x is possible because -1/10 is the value of k. This is just the same with y=kx.
