150/100 = 1.5, so each 1 percent is equal to 1,5, then times 1.5 by 80 and you get 120

Plzzz answer both questions and I will give you 100 points

Answer: 0.79

Hmm <em>ok</em>, so the first step to <em>solve</em> this problem is to find the area of Kimora's living room. The way to do this is:

L*W=A\\Where L= Length, W= Width, and A= Area\\\\L=16, W=10.5\\16*10.5=168

<u>So</u> we have now figured out how many <em>square feet of carpet we need.</em> Now to wrap this up and find the answer, Just simply divide the "A" value by the total cost of the carpet like this:

\frac{132.72}{168}=0.79

And thats it, be sure to Punch that like button and don't be afraid to ask me more questions. I'm here to help!

<h2>Thanks!</h2>

The quadratic equation whose roots are 1/2 and - 1/2 is<br>​
lesya692 [45]

Answer:

4x^2 - 1 = 0

Step-by-step explanation:

x = 1/2, x = -1/2

2x = 1, 2x = - 1

2x - 1 = 0, 2x + 1 = 0

( 2x - 1 )( 2x + 1 ) = 0

4x^2 - 1 = 0

A hovercraft takes off from a platform. Its height (in meters), xx seconds after takeoff, is modeled by: h(x)=-2x^2+20x+48h(x)=?
tangare [24]

Answer: 5 seconds

<u>Step-by-step explanation:</u>

Maximum height is the y-value of the vertex. The number of seconds at maximum height is the x-value (aka axis of symmetry).

h(x) = -2x² + 20x + 48

      a=-2    b=20   c=48

Axis of symmetry: x = \frac{-b}{2a}

                                 = \frac{-20}{2(-2)}

                                 = \frac{-20}{-4}

                                 = 5
