a. 1.5 cm
b. 2 cm
c. 6 cm
d. 3 cm

Option C

Height of DEF = 4cm

Therefore ratio = 1:2

Base = 3cm

Height of ABC = 2cm

Area of ABC = 1/2×b×h

= 1/2×3×4

11.95 g / 6 hours  

Step-by-step explanation:

drug dosage = 460 mg per kg per day

to be administered every 6 hours to a person who weighs 229 pounds

1 pound = 0.453592 kg

229 pounds = 229 × 1 pound = 229 × 0.453592 kg = 103.873 kg

dosage of drug needed for 103.873 kg

460 mg is to 1 kg per day

103.873 kg = 103.873 × 460 mg per 1 kg per day = 47781.58 mg per 103.873 kg per day

number of 6 hours in a day = 24 hours ÷ 6 hours = 4 times per day

dosage needed per 6 hours

47781.58 ÷ 4 = 11945.395 mg for every 6 hours = 11.95 g / 6 hours
