Answer:
$324
Step-by-step explanation:
We need to make a proportion:
![\frac{259.20}{x} = \frac{80}{100}](https://tex.z-dn.net/?f=%20%5Cfrac%7B259.20%7D%7Bx%7D%20%20%3D%20%20%5Cfrac%7B80%7D%7B100%7D%20)
![25920 = 80x](https://tex.z-dn.net/?f=25920%20%3D%2080x)
![x = 324](https://tex.z-dn.net/?f=x%20%3D%20324)
x is 1%. So 100% = 324*100 = 32400 cents = $324
Hope I helped :)
-8d-7=0 i think but not sure i guessed
Answer:
![(C)2\sqrt{7}](https://tex.z-dn.net/?f=%28C%292%5Csqrt%7B7%7D)
Step-by-step explanation:
Given a circle Q represented by the equation:
![(x -11)^2 + (y + 15)^2 = 7.](https://tex.z-dn.net/?f=%28x%20-11%29%5E2%20%2B%20%28y%20%2B%2015%29%5E2%20%3D%207.)
Comparing with the standard form of the equation of a circle center (h,k) of radius r:
![(x-h)^2+(y-k)^2=r^2](https://tex.z-dn.net/?f=%28x-h%29%5E2%2B%28y-k%29%5E2%3Dr%5E2)
We have:
![r^2=7](https://tex.z-dn.net/?f=r%5E2%3D7)
We take the square root to obtain the radius, r of the circle.
![r=\sqrt{7}](https://tex.z-dn.net/?f=r%3D%5Csqrt%7B7%7D)
Since segment KL is a diameter of circle Q; and
Diameter =Radius X 2
Therefore:
![|KL|=2\sqrt{7}](https://tex.z-dn.net/?f=%7CKL%7C%3D2%5Csqrt%7B7%7D)
