1. what is the amount of the bolus dose, in both milligrams and milliliters, that you will administer in the first minute? 
The doses is 0.9 mg/kg and the weight of the patient is 143 pounds. So, the total doses of drug needed will be: 
Total doses= 0.9 mg/kg * 143 pounds * 0.453592 kg/pound= 58.37 mg.

10% of the doses will be given bolus for 1 min, so the amount would be:
Bolus doses= 10%*58.37 mg= 5.837 mg.
In mililiters, it would be: 5.837 mg * 1ml/mg= 5.837 ml.

2. what is the amount of the remaining dose that you will need to administer?
The remaining dose would be 90% of the total dose. You can either calculate it directly or subtract the bolus doses from the total doses.
Remaining doses= total doses- bolus doses= 58.37 mg- 5.837 mg= 52.533mg
