Mathematics
1 answer:
rusak2 [61]4 years ago
6 0

Answer: n=20

Step-by-step explanation:

-4n=-80

Since -4 is being multiplied with n, you divide by -4 to get n by itself. Then you divide -80 by -4 to balance the equation out.

-4n/-4=-80/-4

n=20

You check your answer by pluging 20 in for n in the original equation.

-4(20)=-80

The final answer is n=20

Wewaii [24]

Answer:

y=120,000(1.055)^x

Step-by-step explanation:

we know that

The equation of a exponential growth function is given by

y=a(1+r)^x

where

y is the value of the home

x is the number of years

a is the initial value

r is the rate of change

we have

a=\$120,000\\r=5.5\%=5.5/100=0.055

substitute

y=120,000(1+0.055)^x

y=120,000(1.055)^x

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 (k
Sonbull [250]

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
