<h2>Hello!</h2>

The answer is:

Samir picks $7\frac{9}{8} Kg$ of peppers in the evening.

To solve this problem, we must remember the way to add or subtract mixed numbers.

We must remember the way of adding or subtracting fractions:

$\frac{a}{b}+\frac{c}{d} =\frac{ad+bc}{bd}$

Also, if we need to add or subtract mixed numbers with different denominators, we need to follow the next steps:

- Add or subtract the whole number part

- Add or subtract the fractional numbers.

- Put together both, whole number addition or subtraction result and the addition or subtraction of the fractional numbers.

So,

$a\frac{b}{c}+d\frac{e}{f} =(a+d)\frac{bf+ce}{cf}$

Now, if Samir picks 3 5/8 less peppers in the afternoon than in the evenning, and if he picks 4 3/6 peppers in the afternoon, so:

Let be x the number of peppers that he picks in the evening, so:

$x-3\frac{5}{8}x=4\frac{3}{6}\\\\x=4\frac{3}{6}+3\frac{5}{8}$

Then, simplifying we have:

$x=4\frac{3}{6}+3\frac{5}{8}\\\\x=4\frac{3}{6}+3\frac{5}{8}=(4+3)\frac{24+30}{48}\\\\x=(4+3)\frac{24+30}{48}=7\frac{54}{48}=7\frac{9}{8}$

So, Samir picks $7\frac{9}{8} Kg$ of peppers in the evening.

Have a nice day!

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

a) The table below shows the populations of several states (in millions) and the number of motor vehicle deaths in each. Complet

Cerrena [4.2K]

A.) The completed table is in the attached picture.
Per capita calculation steps
Step 1: Per capita = MV Deaths / Population
Step 2: Convert to Scientific notation
Step 3: Round-off to hundredths (2nd digit from the right of decimal place)
Per 100K people calculation steps
Step 1: Per 100K people = MV Deaths / Population * 100, 000
Step 2: Round-off to tenths (1st digit from the right of decimal place)

B) I used my completed table (attached picture)
Therefore, Indiana has the worst rate with 11.6 MV Deaths per 100K People

C) Again, I used my completed table (attached picture)
Therefore, Illinois has the best rate with 7.3 MV Deaths per 100K People
