horsena [70]

Answer:

No

Step-by-step explanation:

His answer is incorrect.  If we round the dimensions, 3.76 m is almost 4 m, and 5.49 m is almost 5.5 m.  4 × 5.5 = 22.  So his answer should be close to 22 m².

Consider the rational numbers 4/13 and 3/10.
omeli [17]
I believe 4/13 is the bigger number because 0.36>0.3
I suggest using a calculator to check but I believe 3/10 is the rational number because it terminates and doesn't repeat

Drug B has is to be given 10 mg/kg/day in 2 divided doses. The patient weighs 220 pounds. The pharmacy has 250 mg capsules on ha
Rasek [7]

Answer:

a) 996.6 mg

b) 498.96 mg

c) 4

d) 2

Step-by-step explanation:

Given:

Dose to be given = 10 mg/kg/day

Number of dose to be divided = 2

weight of the patient = 220 pounds

now,

1 pound = 0.453 kg

thus,

weight of the patient = 220 × 0.4536 = 99.792 kg

a) Amount of Drug patient should receive per day = dose × weight of patient

or

Amount of Drug patient should receive per day = 10 × 99.792

or

Amount of Drug patient should receive per day = 997.92 mg

b) Now, the dose is divided in to 2 per day

thus,

The amount of drug received per dose = \frac{\textup{Drug received per day}}{\textup{Number of dose per day}}

or

The amount of drug received per dose = \frac{\textup{997.92 mg}}{\textup{2}}

or

The amount of drug received per dose = 498.96 mg

c) weight of capsule = 250 mg

Thus,

capsules received by patient per day = \frac{\textup{Dose per day in mg}}{\textup{weight of capsule in mg}}  

or

capsules received by patient per day = \frac{\textup{997.92}}{\textup{250}}  

or

capsules received by patient per day = 3.99168 ≈ 4

d) Capsules to be received per dose = \frac{\textup{Amount of drug per dose in mg}}{\textup{weight of capsule in mg}}  

or

capsules received by patient per dose = \frac{\textup{498.86}}{\textup{250}}  

or

capsules received by patient per dose = 1.99544 ≈ 2
