So if the test is worth 50 points and you got 84% on it you would get 50 times 84/100 points

so 50/1 times 84/100=(50*84)/(50*2)
this is also (50/50) times (84/2)
so you can take out the 50/50 which equals 1 and get 84/2 which divides to equal 42
so you will get 42 points

If we know that 
50points ---------- 100%
x is ----------------- 84%
Know we can write
x*100%=50*84%      /:100%

x= \frac{50*84}{100}=42 - its the result

It is known that a certain function is an inverse proportion. Find the formula for this function if it is known that the functio
katrin2010 [14]

Answer:

y=\frac{24}{x}

Step-by-step explanation:

We have been given that a certain function is an inverse proportion. We are asked to find the formula for the function if it is known that the function is equal to 12 when the independent variable is equal to 2.  

We know that two inversely proportional quantities are in form y=\frac{k}{x}, where y is inversely proportional to x and k is constant of variation.

Upon substituting y=12 and x=2 in above equation, we will get:

12=\frac{k}{2}

Let us solve for constant of variation.

12\cdot 2=\frac{k}{2}\cdot 2

24=k

Now, we will substitute k=12 in inversely proportion equation as:

y=\frac{24}{x}

Therefore, the formula for the given scenario would be y=\frac{24}{x}.
