Answer:

Step-by-step explanation:
If the point (2,3) is on the terminal side of an angle in standard position.
Adjacent of O, x=2,
Opposite of O, y=3
Next, we determine the hypotenuse, r using Pythagoras Theorem.

Therefore:



2 feet and 1 in. Explanation is subtract 3’8 from 6’4 then add 9in too it. Feet can only go to 12in. But you’ll get 3’4. Then add 9 and you’ll get 3’13 so you’ll get 4’1 and then just subtract that from 6’4 and you get 2’1
Answer: I get c, but double check on your end

Answer:

Step-by-step explanation:
![S= \frac{n}{2 [2a + (n - 1)d]}](https://tex.z-dn.net/?f=S%3D%20%5Cfrac%7Bn%7D%7B2%20%5B2a%20%2B%20%28n%20-%201%29d%5D%7D)
Simplifying the fraction by multiplying d into the (n-1) term,
![s=\frac{n}{2 [2a + (n - 1)d] } = \frac{n}{2[2a + dn - d] }](https://tex.z-dn.net/?f=s%3D%5Cfrac%7Bn%7D%7B2%20%5B2a%20%2B%20%28n%20-%201%29d%5D%20%7D%20%3D%20%5Cfrac%7Bn%7D%7B2%5B2a%20%2B%20dn%20-%20d%5D%20%7D)
Simplifying the fraction by multiplying 2 throughout,

Multiply
on both sides

Cancel the
on the right hand side

Multiply s to the terms,

Move
to the right hand side by subtracting
on both sides

On the right hand side of the equation, take out 

Divide Left hand side by

If you are grounded, there are two options - you are only grounded or you have extra chores too. Therefore, at that point, there is a 100% chance of you already being grounded - we need to figure what percentage of 100 the extra chores is. To find that, we can do 50/85= around 59% percent
