Answer:
8 unit doses
Step-by-step explanation:
A 0.0417% concentration means that 100 mL of solution contains 0.0417 grams = 41.7 mg of the active ingredient.
Cross-multiplying
100 mL ------- 41.7 mg
x mL------- 10 mg
100/x = 41.7/10 --------> x = 1000/41.7 = 23.9808 = 24 mL rounding to the nearest integer.
As a unit dose of Levalbuterol HCL contains 3.0 mL,
we need 24/3 = 8 unit doses to obtain 10 mg of the active substance.
I’m not for sure but I think 6
Answer: Corries’ answer is correct.
1. Take the ratio, and add the parts to make a whole number —> 2:3 —> 2 + 3 = 5
2. Divide the total by 5 —> 30/5 = 6, meaning each part of the ratio is represented by 6 ounces
3. 2 * 6 = 12 and 3 * 6 = 18, meaning 12 ounces of blue paint and 18 ounces of yellow paint were used to make this green
4. Then, divide 12 by 30 and simplify to find out which student is correct
5. 40% of the paint in the container is blue paint, find the fraction equivalent to 40% which is 2/5

Step-by-step explanation:
the perimeter =
4+4+6+4.5+2+4+4+2 =
30.5 cm
the area of:
• the bigger rectangle = 6×4 = 24 cm²
• the smaller triangle = 4×2 = 8cm²
• the triangle = ½×2×4 = 4cm²
the total area = 24+8+4 = 36cm²
