First one is geometric
Second one is arithmetic
Because geometric sequences have patterns
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
Let t, f, and s be the amount of 25%, 40%, and 60% solutions used.
We are told s=3f. The general equation is:
100(0.25t+0.4f+0.6s)/(t+s+f)=45, and using s=3f we have:
(0.25t+0.4f+1.8f)/(t+4f)=0.45
(0.25t+2.2f)/(t+4f)=0.45
0.25t+2.2f=0.45t+1.8f
0.25t+0.4f=0.45t
0.4f=0.2t
t=2f, remembering that s=3f, will allow us to solve for f
t+s+f=60, using t and s from above
2f+3f+f=60
6f=60
f=10 L then
s=3f=30 L and t=2f=20L
So 20L of 25%, 10L of 40%, and 30L of 60% acid solutions need to be mixed to make 60L of 45% acid solution.
Answer:
1st one
Step-by-step explanation
I have NEVER in my life seen a dog with pants on its back legs, only on both so yeah.
8x + 4y + 6 <= 70
x = # of salads
y = # of drinks
If he buys 4 salads then
8x + 4y + 6 <= 70
8(4) + 4y + 6 <70
32 + 4y + 6 <= 70
4y + 38 <= 70
4y <= 32
y <= 8
