V/-8 = 4v
V= -32v
V+32v=0
33v=0
V=0
Answer:
1 : 656250
Step-by-step explanation:
It is given that we need to dissolve 8 tablets of active ingredient B, each containing 3 mg, in 15,750 mL.
Tablets = 8
Weight of each tablet = 3 mg
Total wight of tablets = 8 × 3 = 24 mg
Total volume = 15,750 mL.
1 mL = 1000 mg
Total volume = 15,750000 mg
We need to find the ratio strength (w/v).



Therefore, the ratio strength (w/v) is 1 : 656250.
Answer:
please I can't see any question
but the equation of a line is
y- y1 =m(x-x1)
where m is the the gradient of the line
The line on that graph is sloping down as it proceeds from
left to right, it drops 3 units for every 1 unit to the right, and
it crosses the y-axis at y=1 .
So the equation of that line is y = -3x + 1 .
