Divide each number by 3 to get the next number. The ratio is 1/3

(7 − 3i) • (2 − i) 4 i 14 3i 11 − 13i < 14 − 10i

gavmur [86]

<span>So... We distribute so that... 7 * 2 = 14 7 * i = 7i then -3i * 2 = -6i -3i * -i = 3i?
</span><span>then combine like terms... 7i - 6i + 3i = 4i so 14 + 4i?</span>

A 125-mL container of amoxicillin contains 600 mg/5 mL. How many milliliters would be used to administer 400 mg of amoxicillin?

Dovator [93]

Answer:

3.33 milliliters.

Step-by-step explanation:

We have been given that a 125-mL container of amoxicillin contains 600 mg/5 mL.

First of all, we will find amount of mg's of amoxicillin per ml as:

$\text{Concentration of amoxicillin per ml}=\frac{\text{600 mg}}{\text{5 ml}}$

$\text{Concentration of amoxicillin per ml}=\frac{\text{120 mg}}{\text{ml}}$

Now, we will use proportions as:

$\frac{\text{1 ml}}{\text{120 mg}}=\frac{x}{\text{400 mg}}$

$\frac{\text{1 ml}}{\text{120 mg}}\times \text{400 mg}=\frac{x}{\text{400 mg}}\times \text{400 mg}$

$\frac{\text{400 ml}}{120 }=x$

$\text{3.33 ml}=x$

Therefore, 3.33 milliliters would be used to administer 400 mg of amoxicillin.

Please answer this !! Will mark brainliest answer !

Kay [80]

Answer:

Step-by-step explanation:

Area=Length x Width

So you start with what you know

Length or in this case height=4x

Width=3x+1

Now you just plug it in

A=4x(3x+1)

Distribute the 4x to both terms (3x & 1)

A=12x^2+4x

Since we do not know what x is that would be your simplified answer.

I dont know how to do this

The formula of a surface area of a cylinder:
$S.A.=2\pi r(r+H)$

We have:
$r=1m;\ H=10m$
substitute:
$S.A.=2\pi\cdot1\cdot(1+10)=2\pi\cdot11=22\pi\ m^2\approx22\cdot3.14=69.08\ m^2$
