Prochlorperazine (Compazine) for injection is available in 10-mL multiple dose vials containing 5 mg/mL. How many 2-mg doses can

be withdrawn from the vial?
Mathematics

Answer:

25

Step-by-step explanation:

Given:

Volume of Prochlorperazine injection available = 10 mL

Dose per vial = 5 mg/mL

Now,

The total mass of dose present in 10 mL = Volume × Dose

or

The total mass of dose present in 10 mL = 10 × 5 = 50 mg

Thus,

The number of 2 mg dose that can be withdrawn = \frac{\textup{50 mg}}{\textup{2 mg}}

or

The number of 2 mg dose that can be withdrawn = 25

Sholpan [36]

Complete question :

En un concesionario de coches hay modelos de varios colores. Los rojos suponen 1/6 del total, los azules, 2/9 del total, y los blancos, 4/15 del total.

a)¿Cuál de esos colores es el más frecuente?

b) Si hay 40 coches azules, ¿cuántos hay en total?

Responder:

Coches blancos

180 coches

Explicación paso a paso:

Dado que:

Rojo = 1/6 del total

Azul = 2/9 del total

Blanco = 4/15 del total

Para determinar qué color es el más alto, convierta los valores en decimal:

1/6 = 0,166667

2/9 = 0,2222

15/4 = 0,26667

Por lo tanto;

4/15> 2/9> 1/6

Por tanto, los coches blancos son los que más

2.)

Sea Número total = x

Por lo tanto,

2/9 de x = 40

2x / 9 = 40

2x = 360

x = 180

Por tanto, hay 180 coches en total.

Triangle H N K is shown. Angle H N K is 90 degrees. The length of hypotenuse H K is n, the length of H N is 12, and the length o
Mazyrski [523]

Answer:

13

Step-by-step explanation:

From the question, we are given a triangle HNK with an angle of 90°

The length of hypotenuse H K is n,

the length of HN is 12

the length of N K is 6.

From the above values, obtained in the question, we can see that this is a right angled triangle.

We are asked to find the length of the hypotenuse.

We can use Pythagoras Theorem of solve for this.

c² = a² + b²

where c = HK = n

a = NK = 6

b = HN = 12

c² = 6² + 12²

c² = 36 + 144

c² = 180

c = √180

c = 13.416407865

Approximately to the nearest whole number = 13

Therefore the value of HK = n = 13

We can also use Law of Cosines as given in the question to solve for this.

a² = b² + c² - 2ac × Cos A

where c = HK = n

a = NK = 6

b = HN = 12

Hence

c² = a² + b² - 2ab × Cos C

c = √ (a² + b² - 2ab × Cos C)

Where C = 90

c = √ 6² + 12² - 2 × 6 × 12 × Cos 90

c = 13.42

Approximately to the nearest whole number ≈ 13

Therefore the value of HK = n = 13

- The table shows the number of each type of sports card that Jaclyn has
djverab [1.8K]

Answer:

7:50

Step-by-step explanation:

The table shows the number of each type of sports card that Jaclyn has collected, so

number of baseball cards = 45

number of basketball cards = 14

number of football cards = 20

number of soccer cards = 21

total number of cards = 45 + 14 + 20 + 21 = 100

Hence the ratio between the number of basketball cards and the total number of cards is

14 : 100=7:50

Corey bought 2 1/2 liters of paint for $60. What was the cost per liter of paint
goldfiish [28.3K]

Hello there!

Answer:

$24

Step-by-step explanation:

In order to find the answer to your problem, we're going to need to find out how much ONE liter of paint costs.

Lets gather the information of what we know:

2 1/2 liters of paint

↑ Cost $60.

With the information we know, we can solve to find the answer.

In order to get the answer, we would need to divide 60 by 2 1/2 (or 2.5). We would need to do this because when we divide it, it would allow us to get the cost for 1 liter.

Lets solve:

60 \div 2.5=24

When you divide, you should get the answer of 24.

This means that one liter of paint cost $24.

$24 should be your FINAL answer.
