Answer:
10/18
Step-by-step explanation:
To convert 1.8 to a reciprocal, you first need to change it into a fraction.
1.8 basically expresses 1 
which equals 
.
Since a reciprocal is just switching the top and bottom of a fraction, your reciprocal of 1.8 will be 
.
You can simplify this if you want, to get 
. Either one is correct.

Answer:
7/40
Step-by-step explanation:
Since 1 ounce is 1/20 of 20 ounces, she needs to use 1/20 of 3 1/2 cups.
1/20 * 3 1/2 = 1/20 * 7/2 = 7/40
Answer:
10 + 5i & 10 - 5i
Step-by-step explanation:
10 + 5i is still just 10 + 5i because we treat i like it's x.
Complex conjugate if I remember correctly is like a + or - form, so I believe 10 - 5i is correct?
Hope this helped.
Answer:
15mg/ml
Step-by-step explanation:
Percent mass per volume ( % m/v) is unit expression that tells us how many grams of a solute that we can find 100 ml of a particular solution.
In the above question, we are asked to express 1.5%w/v Bepotastine besilate (BEPREVE) ophthalmic solution as mg/mL
Step 1
1.5% w/v = 1.5 g of Bepotastine besilate (BEPREVE) in 100ml ophthalmic solution
Hence, if
100ml = 1.5g
1 ml = y g
We Cross Multiply
100ml × yg = 1 ml × 1.5g
yg = 1 ml × 1.5g/100ml
= 0.015g
Therefore, in 1 ml we have 0.15 g.
Step 2
Since we are asked to express as mg/ml
We convert 0.015g to mg
1 gram = 1000 milligrams
0.015 grams =
Cross Multiply
0.015grams × 1000 milligrams/ 1 gram
= 15 mg
Therefore, the concentration in mg/ml of 15% m/v of Bepotastine besilate (BEPREVE) ophthalmic solution is 15mg/ml
