answer= 1
5 x 2 - 3^2
1. First simplify exponents
= that is nine
2. Then Do 5 x 2- 9
5 x 2=10
10-9
= 1
If 1 ml of volume contains 1 mg of epinephrine, then 0.1 ml of volume contains 0.1 mg of epinephrine.
Let x be the number of ml you need.
Ratio: 1 ml is to 1 mg as x ml is to 0.1 mg
(1 ml)/(1 mg) = (x ml)/(0.1 mg)
Cross multiply.
1 * x = 1 * 0.1
x = 0.1
Answer: 0.1 ml
Answer:
a)The quantity (mg) of medication used to the nearest hundredths is 212.75mg
b) The quantity (mg) of the original medication left in the stock bottle to the nearest tenths is 287.3 mg.
Step-by-step explanation:
For question a) 125mg + 62.5mg +25.25mg= 212.75 mg to the nearest hundredths
b) The quantity left can be calculated by subtracting 212.75 from 500
500 - 212.75 = 287.25 to the nearest tenth is 287.3mg
The answer is 100. If you divide 791.3 by 7.913 you get 100. Then multiply 100 by 7.913 and the answer is 791.3. Hope this helps!
