If 15 mL of a solution contains 75 mg of medication, how many mg of medication are in 60 mL of solution?

Answers

Given:

15 mL of a solution contains 75 mg of medication.

To find:

How many mg of medication are in 60 mL of solution?

Solution:

We have,

Medication in 15 mL of a solution = 75 mg

Medication in 1 mL of a solution = [tex]\dfrac{75}{15}[/tex] mg

                                                     = [tex]5[/tex] mg

Medication in 60 mL of a solution = [tex]60\times 5[/tex] mg

                                                        = [tex]300[/tex] mg

Therefore, 60 mL of a solution contains 300 mg of medication.

Reduce to simplest form.

(-6-4) divided by (-5)

Answers

Answer:

2

Step-by-step explanation:

Simplify the following:

(-6 - 4)/(-5)

Hint: | Group the negative terms in -6 - 4 together and factor out the minus sign.

-6 - 4 = -(6 + 4):

(-(6 + 4))/(-5)

Hint: | Evaluate 6 + 4.

6 + 4 = 10:

(-10)/(-5)

Hint: | In (-10)/(-5), the numbers 10 in the numerator and -5 in the denominator have gcd greater than one.

The gcd of 10 and -5 is 5, so (-10)/(-5) = (-(5×2))/(5 (-1)) = 5/5×(-2)/(-1) = (-2)/(-1):

(-2)/(-1)

Hint: | Cancel common terms in the numerator and denominator of (-2)/(-1).

(-2)/(-1) = (-1)/(-1)×2 = 2:

Answer: 2

The equivalent value of the fraction is A = 2

Given data ,

Let the equation be represented as A

Now , the value of A is

Let the numerator of the fraction be p

Let the denominator of the fraction be p

Now , A = p/q

when the value of p = ( -6 - 4 )

And , when the value of q = ( -5 )

On simplifying the equation , we get

A = ( -6 - 4 ) / ( -5 )

So , the left hand side of the equation is equated to the right hand side by the value of ( -6 - 4 ) / ( -5 )

A = ( -6 - 4 ) / ( -5 )

A = ( -10 ) / ( -5 )

On simplifying , we get

Divide by -1 on both numerator and the denominator , we get

A = 10/5

A = 2

Therefore , the value of A = 2

Hence , the fraction is A = 2

One political factor that caused World War II was the Treaty of Versailles. The Treaty of Versailles created political tension between countries, as some provisions that were outlined within the treaty were unfair towards some of the parties involved. Take Italy for example; thousands of Italians had died in the war, but Italy was not given the land and reparations they were promised. This led to a rise in nationalism, and more Italians feeling resentment towards the Triple Entente for their abundant debt and little assistance. This is also an economic factor that caused World War II, as the aftermath of World War II left Italy in ruins, both literally and financially, and made it so that they desperately needed hope. This, in turn, led to Benito Mussolini coming into power, boasting promises of a greater Italy in the near future. Similarly, the Treaty of Versailles left Germany in a lot of debt, and many German citizens were suffering. Hitler, a charismatic leader who took advantage of the political and economic turmoil, took over and gave Germany an excuse for their problems: the Jewish population. Another economic factor that caused World War II was the worldwide depression, which put a lot of countries in a very bad position. Also, the rise of fascism and totalitarianism definitely contributed to the way World War II started, as many of the agitators of the war were in the Axis powers, and were under totalitarian dictators. Match the name to the correct description. 1. Polyphemus sea monster with six dog heads 2. Lotus-eaters enemies who killed six men from each of Odysseus's ships 3.
