5. While still in the hospital, the doctor writes an order for an antibiotic at 300mg/kg daily. You are nervous now because the

nurse was wrong before. If you weigh 123 lb, determine how many milligrams you should be given.

The correct answer is 16737 mg

Explanation:

The first step to solve this problem is to convert the weight to kilograms because the dosage of the antibiotic is given in milligrams per kilo. This can be done by multiplying the pounds by 0.453 considering each pound is equal to 0.453 kilos. The process is shown below:

123 lb x 0.453 = 55.791 kg

Now, simply multiply the kilos by the recommended dose:

55.791 kg x 300 mg/kg = 16737 mg

Also, this can be converted to grams by dividing the number into 1000 (1000 mg = 1 g)

16737mg ÷ 1000 =  16.737 grames

Answer:

A. 2564 cm^2

Step-by-step explanation:

There are two triangles (Which both are the same) and three different rectangles.

1. Let's solve the area of the triangles first!

Formula: bh(1/2)

10(26)(1/2)

130

2. Now, let's multiply by 2 since there's two of them:

130(2) = 260

3. So, we got 260. Let's find the area of the three rectangles!

Formula: bh

Rectangle A: 28(36) = 1008

Rectangle B: 10(36) = 360

Rectangle C: 26(36) = 936

4. Add the area of the triangles and the rectangles!

260 + 1008 + 360 + 936 = 2564

So the surface area is 2564 cm^2

Hope this helps! <3

Drag and drop each pair of lines into the correct category to indicate whether the pair of lines are parallel, perpendicular, or
ANTONII [103]

Answer:

Step-by-step explanation:

<em>(1).</em> \frac{1}{7} x + y = 9 and y = - 7x <em>( Neither )</em> ; lines intersect.

<em>(2).</em> y = 3x - 3; 12x - 4y = 12 <em>( Neither ) </em>; Lines are overlapped or both equation are of the same line.

<em>(3).</em> 7y = 2x + 1; 14x + 4y = 12 <em>( Perpendicular )</em> ; m_{1} = \frac{2}{7} and m_{2} = - \frac{7}{2} , slopes are opposite reciprocals.

<em>(4).</em> x - 4y = 18; y = x + 4 <em>( Neither )</em> ; lines intersect.

<em>(5).</em> 3x - 4y = - 1; 3y = - 4x + 5 <em>( Perpendicular )</em> ; m_{1} = \frac{3}{4} and m_{2} = - \frac{4}{3} , slopes are opposite reciprocals.
