Answer: -5/2 or 1/6
Step-by-step explanation:
I6n + 7I = 8
Therefore (6n + 7) = 8 or -8 because modulus means we're only getting it's absolute value, (it's positive value) meaning it could equal 8 or -8 before it's modulus'ed.
Therefore 6n + 7 = 8
or 6n + 7 = -8
Leaving us with:
6n = 1
6n = -15
So n = 1/6
or n = -5/2 (-2.5)
Answer:
1) 
2) 
3) 
4) 
Step-by-step explanation:
1) Value of 
since sin45° = 1/√2
Therefore
2).Value of 
Since cos 30° = √3/2
Therefore
3). Value of 
since tan 60° = √3
therefore
4). Value of 
Since sin90°=1
Therefore
The answer is 45 because 2.50 times 18=45
Answer:
1) It would be about a 55% increase. 2) It would be about a 79% increase
Step-by-step explanation:
I used process of elimination to figure out how much of a percentage would be needed by just multiplying 210 by different percentages until I found the answer.
Sorry I don't have like a definite formula or anything for you to figure these questions out... I hope someone else answers with a more definite answer!
