Answer: 2.016 km weekly

Detailed explanation:

Starting value: 1200 cm per hour

It is known that 1\text{ km}=100000\text{cm}\\\\\Rightarrow\ 1\text{ cm}=\dfrac{1}{100000}\text{ km}

Furthermore,

1\text{ day}=24\text{ hours} \\\\\Rightarrow\ \text{1 week}=7\times24\text{ hours}=168\text{hours}\\\\\Rightarrow\ \text{1 hour}=\dfrac{1}{68}\text{ week}

\text{ 1200 cm per hour}=\dfrac{1200}{100000}\times\dfrac{1}{\dfrac{1}{168}}\\\\=\dfrac{1200}{100000}\times168=2.016\text{ km per week}

In this scenario, we have a function of the following form: A: initial amount, b: rate of decrease, x: time in years. Plugging in the values results in an exponential decay function suitable for this situation: y = 1300 * (0.97) ^ x. The estimated fish population in 2010 is then calculated to be approximately 1083.

Answer: Children who weigh 10 pounds require 12 teaspoons, those at 15 pounds need 18 teaspoons, and for 30 pounds, it is necessary to have 36 teaspoons.

Step-by-step explanation:

We have a recommended dose of 40 mg per 2.2 pounds of weight, given in three doses throughout the day every 8 hours.

Thus, for a single pound, the daily required dosage is calculated as \dfrac{40}{2.2}=18.18\ ml.

Each individual dose corresponds to \dfrac{18.18}{3}=6.06\ ml of the drug.

This means for one pound, the dosage needed per dose is 6.06 ml.

Thus, for 10 pounds, the calculation is 10 x 6.06 ml = 60.6 ml

To convert ml to teaspoons, knowing that 1 teaspoon equals 5 ml, we find: (60.6 ml ÷ 5) = 12.12 ≈ 12 teaspoons.

For a weight of 15 pounds, the drug requirement is 15 x 6.06 ml = 90.9 ml.

This translates to (90.9 ml ÷ 5) = 18.18 ≈ 18 teaspoons.

For the weight of 30 pounds, it is calculated as 30 x 6.06 ml = 181.8 ml.

Converting this gives us (181.8 ml ÷ 5) = 36.36 ≈ 36 teaspoons.

Therefore, children weighing 10 pounds need 12 teaspoons, those at 15 pounds require 18 teaspoons, and those at 30 pounds need 36 teaspoons.
