a doctor order calls for you to administer 0.1 mg of epinephrine in stock is a 1ml ampule that contains1 mg of epinephrine cacul

Darina [25.2K]

If 1 ml of volume contains 1 mg of epinephrine, then 0.1 ml of volume contains 0.1 mg of epinephrine.

Let x be the number of ml you need.

Ratio: 1 ml is to 1 mg as x ml is to 0.1 mg

(1 ml)/(1 mg) = (x ml)/(0.1 mg)

Cross multiply.

1 * x = 1 * 0.1

x = 0.1

Answer: 0.1 ml

Simplify 1)5x+3=x+13 2)5/2x-1/X =1/6

Artyom0805 [142]

Step-by-step explanation (Question 1):

Step 1: (Question 1): Subtract x from both sides.

5x+3=x+13

5x+3−x=x+13−x

4x+3=13

Step 2: (Question 1): Subtract 3 from both sides.

4x+3−3=13−3

4x=10

Step 3: (Question 1): Divide both sides by 4.

4x/4 = 10/4

FIRST ANSWER: x = 5/2

Step-by-step explanation (Question 2):

Step 1: (Question 2): Multiply by LCM

15x^2 - 6 = x

Step 2: (Question 2): Solve 15x^2

15x^2 - 6 = x:

x = 2/3

x = -3/5

Step 3: (Question 2): Solve

ANSWER: x=0.666667 or x=−0.6

See Attachment 1 for question 1 steps (FULL)

See Attachment 2 for question 2 steps (FULL)

Answer:

Find the unit rate for number of parts manufactured per hour if 1116 parts are made in 7 hours. Round to the nearest integer.

o-na [289]

The unit rate is obtained by dividing the amount of work done by the unit time. In the problem, we are already given the total number of parts manufactured (amount of work done) and the total amount of time to manufacture (7 hours).

Obtaining the unit rate is as simple as dividing 1116 parts by 7 hours, as shown below:

Unit rate = 1116 parts / 7 hours
Unit rate = 159.42857

Therefore the unit rate is approximately 159 parts/h.

ser-zykov [4K]

Answer:

$(x+2\sqrt{3} )(x+\sqrt{3} )$

Step-by-step explanation:

$x^2 + 3\sqrt{3}x + 6\\=> x^2 + \sqrt{3}x + 2\sqrt{3}x +6\\=> x( x+\sqrt{3}) + 2\sqrt{3}(x+\sqrt{3} )\\ => (x+2\sqrt{3} )(x+\sqrt{3} )$
