Answer:
1200 ounces
Step-by-step explanation:
How much of an alloy that is 10% copper should be mixed with 600 ounce of an alloy that is 70%copper in order to get an alloy that is 30%copper?
Let us represent
Number of ounce of 10% copper = x
Hence, our Equation =
x × 10% + 600 × 70% = (x + 600) × 30%
0.1x + 420 = (x + 600)0.3
0.1x + 420 = 0.3x + 180
Collect like terms
0.3x - 0.1x = 420 - 180
0.2x = 240
x = 240/0.2
x = 1200 ounces
Answer:the usual dosage would be
54.55 milligrams.
Step-by-step explanation:
When Ibuprofen is given for fever to children 6 months of age up to 2 years, the usual dose is 5 milligrams (mg) per kilogram (kg) of body weight when the fever is under 102.5 degrees Fahrenheit. This means that the usual dose for a 18 month old child would be 5 milligrams (mg) per kilogram (kg) of body weight. Since the weight of the child is 24 pounds, we would covert 24 pounds to kilogram.
2.2 pounds = 1 kg
24 pounds = 24/2.2 = 10.91 kg
Therefore, the dosage would be
5 × 10.91 = 54.55 milligrams
