The area of a sector = 0.5 * radius^2 * central angle measure (in radians)
So that:
![Area_{sector}= \frac{1}{2} * 6^2* \frac{120}{180}*\pi=12\pi=37.69911 \\ Area_{sector}=37.7](https://tex.z-dn.net/?f=Area_%7Bsector%7D%3D%20%20%5Cfrac%7B1%7D%7B2%7D%20%2A%206%5E2%2A%20%5Cfrac%7B120%7D%7B180%7D%2A%5Cpi%3D12%5Cpi%3D37.69911%0A%5C%5C%0AArea_%7Bsector%7D%3D37.7%20%20%20)

Basically, the higher the price an item is the more you will be taking off of it if it is 10 percent off. For example, at $50, 10 percent off is $5, but at $55, it’s $5.50. There is more to take away, making the final price less than the original. Hope that make sense!
Answer:
25
Step-by-step explanation:
Cancel out 19^0, then exponentiate and simplify by multiplying exponents. Then simplify the terms. This leaves you with 2^-16*5^10*5^-8*2^16 which equals 5^2 which is 25
W= width
L= length= 2W-4
Perimeter= 70
FIND WIDTH:
P= 2(L + W)
P= 2L + 2W
substitute 2W-4 for L
70= 2(2W-4) + 2W
multiply 2 by all in parentheses
70= (2*2W) + (2*-4) + 2W
70= 4W - 8 + 2W
combine like terms
70= 6W - 8
add 8 to both sides
78= 6W
divide both sides by 6
13= W
FIND LENGTH:
substitute w=13 to find width
L= 2W-4
L= 2(13)-4
L= 26-4
L= 22
CHECK:
P= 2(L + W)
70= 2(22 + 13)
70= (2*22) + 2(13)
70= 44 + 26
70= 70
ANSWER:
length= 22 inches
width= 13 inches
Hope this helps! :)
