Answer: 1/250

Step-by-step explanation:

Given the recurring decimal : 0.004

Firstly:

Let x = 0.004 - - - (1)

Due to the number of decimals places and value of x;

We multiply (1) by 1000 to obtain an integer

Multiply (1) by 1000

1000x = 4 - - - (2)

From (2) we can solve for x and leave our answer as a fraction.

Divide (2) by 1000 to obtain the value of x

1000x / 1000 = 4 / 1000

x = 1 / 250

Recall x = 0.004

Therefore, x = 0.004 = 1/250

If an injectable solution contains 25μg of a dug substance in each 0.5 mL, how many milliliters would be required to provide a p

Kay [80]

Answer:

5mL would be required to provide a patient with 0.25 mg of the drug substance.

Step-by-step explanation:

The problem states that an injectable solution contains 25μg of a dug substance in each 0.5 mL, and asks how many milliliters would be required to provide a patient with 0.25 mg of the drug substance.

So, the first step is the conversion of 25ug to mg, since the problem asks the answer in mg.

Each mg has 1000ug. So

1mg - 1000ug

xmg - 25ug

1000x = 25

$x = \frac{25}{1000}$

x = 0.025 mg

It means that each 0.5mL of the solution contains 0.025mg of the drug. How many milliliters would be required to provide a patient with 0.25 mg of the drug substance.

0.5mL - 0.025mg

xmL - 0.25mg

0.025x = 0.5*0.25

$x = \frac{0.5*0.25}{0.025}$

x = 10*0.5

x = 5mL

5mL would be required to provide a patient with 0.25 mg of the drug substance.

Must show work to get brainly.

Answer:

D. 32, 8, 256

Step-by-step explanation:

You want to get the same base numbers so you can add exponents

sqrt(2)^(4x+1) = 2^(2x+1/2)

16^x = 2^4x

4^(8x-6) = 2^(16x-12)

Now you can drop the bases and do the following equation

2x+1/2 + 4x = 16x-12

Solve for x, which is 1.25

Plug 1.25 back into the original numbers and you get the answers for the dimensions and area.
