Answer:
3.92$
Step-by-step explanation:
The first step is to deduct 20% of 4.50 from 4.50.
20% of 4.50 is 0.2 x 4.50 = .90
4.50 - 0.90 = 3.60
That's the new price without the sales tax.
Now we need to add 9% of 3.60 to 3.60 to get the final cost.
9% of 3.60 is .09 x 3.60 = 0.32
3.60 + .32 = $3.92
Hope it helps.. If yes mark me BRAINLIEST

Answer:
2 + x
2 + (x)
x + (2)
Step-by-step explanation:
Switch them around.
The volume of a cone is (1/3)πr2h.
In this problem r=2h or h=(1/2)r
Hence V = (1/6)πr3
dV/dt = (1/2)πr2 dr/dt
With this information you should now be able to answer the question. Remember the relation between r and h!
never mind i was right
im also so sorry if you dont understand or its not one of the answers
We have the equation:
![9x^2-12x+4=0](https://tex.z-dn.net/?f=9x%5E2-12x%2B4%3D0)
so:
![a=9\qquad b=-12\qquad c=4](https://tex.z-dn.net/?f=a%3D9%5Cqquad%20b%3D-12%5Cqquad%20c%3D4)
and:
![\Delta=b^2-4ac=(-12)^2-4\cdot9\cdot4=144-144=\boxed{0}](https://tex.z-dn.net/?f=%5CDelta%3Db%5E2-4ac%3D%28-12%29%5E2-4%5Ccdot9%5Ccdot4%3D144-144%3D%5Cboxed%7B0%7D)
This equation has one solution.
