B. 1.08mL
1 lb = 2.2 kg
5 lb = 2.27 kg
2.27kg × 12mg = 27.24 mg
Divide 27.42 mg by 2.5 = 10.896mg
Now change the mg to mL
10.896 ÷ 10 = 1.0896

Answer:
x=(-7+√13)/6
or
x= (-7 -√13)/6
Step-by-step explanation:
0.03x^2 = 0.07x + 0.03=0
first, multiply everything by 100 to make life easier
3x^2 +7x+3=0
then use quadratic formula
D=b^2 -4ac
D=49-3*3*3 = 13
x=(-7+√13)/6
or
x= (-7 -√13)/6
