Answer: the percent change in attendance from 2014 to 2015 is 11.54%
Step-by-step explanation:
In 2014, the total attendance at Jefferson school's Fall festival was 650.
In 2015, the attendance was 575. The change in the number of attendees between 2014 and 2015 is 650 - 575 = 75
There was a decrease in the number of attendees between 2014 and 2015.
The percent change in attendance from 2014 to 2015 would be attendance in 2015 divided by attendance in 2014 and multiplied by 100. It becomes
75/650 × 100 = 11.54%
The answer is D 2km it's trying to trick you but no matter what angle the land is at the distance is still the same
Answer:
This may not be entirely satisfied proof but you should get the idea.
Proof: Start with 1 = -1.
Then we know that if a= b then a + c = b + c and also a / c = b / c.
So we can add 1 to both sides.
We have 1 + 1 = -1 + 1 ⇒ 2 = 0.
Now divide both sides by 2 and we would have 1 = 0.
Now add both sides by 1. This yields 2 = 1.
Therefore if 1 = -1 then 2 = 1.
QED
Answer: x=9
Explanation: All 3 angles of a triangle add up to 180, so basically the equation is (3x-5)+(7x+5)+90=180.
Then you add your like terms, so 3x+ 7x=10x and -5+5=0, which cancels out. Now we have 10x+90=180, we subtract the 90 from 180 to see what 10x is equal to and we get 90. So 10x=90. We divide 10 from 90 and we get the value of X, which is 9.
