Answer:
The center of the circle is 
.
Step-by-step explanation:
The center of the circle is the midpoint of the segment between the endpoints. We can determine the location of the center by this vectorial expression:
(1)
Where:
- Center.
, 
- Location of the endpoints.
If we know that 
and 
, then the location of the center of the circle is:
The center of the circle is .
Answer:
w > -1
Step-by-step explanation:
Hello There!
We want to simplify this expression to be more specific we want to isolate the variable (w) using inverse operations
So we want to get rid of the 8 in 8w
8w is the same as 8 times w (multiplication)
The inverse of multiplication is division so to get rid of the 8 we want to divide by 8 but remember whatever we do to one side we want to do to the other side. So we divide each side by 8
-8/8 = - 1
8w/8=w
we're left with w > -1
Answer:
15%
Step-by-step explanation:
When looking at the problem, you are given the total number of seats and the number of seats that are in the sun. There are two ways that you can go about this problem
1) In this method, you want to find how many seats are not in the sun. First you would take the total number of seats (9400) minus the number of seats in the sun (7990) to find the amount of seats not in the sun. 9400 - 7990 = 1410 seats. After this, you simply want to find the percentage by doing the part over the whole multiplied by 100 and it would look like this: (1410 / 9400) * (100) = 15%
2) You can find the percentage of seats in the sun and you know that it's compliment is the seats out of the sun. So it would look similar to the last one by doing part over whole multiplied by 100: (7990 / 9400) * (100) = 85% in the sun. Then you would subtract that from 100%: 100 - 85 = 15% of seats not in the sun.
I hope that this helps!
