What you need to is find out how much 3/8 is, compared to 3/4. since 4 is half of 8 you have to multiply 3/4 by 2, which gives you 6/8. 6/8 is greater than 3/8, therefore Mariah ran farther

Answer:
Answer is 16/12
Step-by-step explanation:
Tan is Opposite by Adjacent. the opposite side is 16, adjacent side is 12 and hypotenuse is 20.
so O/A= 16/12
Answer:
![Z= 75*6 -250=200](https://tex.z-dn.net/?f=%20Z%3D%2075%2A6%20-250%3D200)
So then the correct answer is B. $200.
Step-by-step explanation:
Notation
Let X be the average contribution size before John makes his contribution.
Let Y be the total contribution size before John makes his contribution.
Let Z be John's contribution.
We know that for this case $ 75 represent the original average amount before the contribution with 50% increase so we can set up the following equation in order to find the original average amount
![1.5 X = 75](https://tex.z-dn.net/?f=%201.5%20X%20%3D%2075)
And solvong for X we got:
![X = \frac{75}{1.5}= 50](https://tex.z-dn.net/?f=%20X%20%3D%20%5Cfrac%7B75%7D%7B1.5%7D%3D%2050)
Now we can find the total contribution before the donation with the following proportion:
![\frac{50}{1}= \frac{Y}{5}](https://tex.z-dn.net/?f=%20%5Cfrac%7B50%7D%7B1%7D%3D%20%5Cfrac%7BY%7D%7B5%7D)
![Y = 250](https://tex.z-dn.net/?f=%20Y%20%3D%20250)
And then with the formula of average taking in count the 6 values we can find the size of donation Z like this:
![\frac{Y+Z}{6}= 75](https://tex.z-dn.net/?f=%20%5Cfrac%7BY%2BZ%7D%7B6%7D%3D%2075)
![\frac{250+Z}{6}= 75](https://tex.z-dn.net/?f=%20%5Cfrac%7B250%2BZ%7D%7B6%7D%3D%2075)
![Z= 75*6 -250=200](https://tex.z-dn.net/?f=%20Z%3D%2075%2A6%20-250%3D200)
So then the correct answer is B. $200.
