Answer 1

4

Explanation:

For each kilogram of mass,
`0.2+4(0.1)=0.6` milligrams are needed.

Thus,
`0.6(10)=6` milligrams are needed.

This is equal to 4 mL

Answer 2

4 ml

Explanation:

You want to know how many mL of medicine is needed for 5 days when the dose is 0.1 mg/kg per day and the concentration is 1.5 mg/mL. The dose on the first day is double that for the rest of the days.

Days

The dose on the first day is equivalent to the dose for 2 days, so we can simply add 1 day to the time period: 5 +1 = 6 days of 0.1 mg/kg/day.

Dose

The total amount required will be ...

(0.1 mg/kg/day) × (10 kg) × (6 days) = 6.0 mg

At a concentration of 1.5 mg/mL, the quantity required is ...

(6.0 mg)/(1.5 mg/mL) = 4.0 mL

For 5 days, the dog will need 4.0 mL of medicine.

Additional comment

Each day except the first, the dog should receive 2/3 mL of medicine. On the first day, the dog should get 4/3 mL.
