You just set up a proportion. 
36/80=18/x
x= 40
36/80=x/20
x=9

The first answer is 40, and the second is 9

hope this helps (:

A zombie lost 3 limbs each day for 4 days.
blondinia [14]

Answer:

-12 tells us the amount of limbs lost.

Explanation:

-3 means that the zombie lost 3 limbs.

If the zombie loses three limbs every day for 4 days, it results in the zombie losing 12 limbs and so therefore -12.

-3 x 4 = -12

-12 is the product of the equation.

hope that helps

The vertex of this parabola is at (-5,-2). when the x-value is -4, the y-value is 2. what is the coefficient of the squared expr
Westkost [7]
Vertex:  (-5,-2); parabola opens up; 

General form of the equation for a vertical parabola opening up is:

y-k = a(x-h)^2; knowing that the vertex is at (-5,-2), we can write:

y+2 = a(x+5)^2.  We need to find the value of the coefficient a.

From the graph we see that y is 10 when x is approx. -1 3/4 (or -7/4).

subst. these values into y+2 = a(x+5)^2, we get:

10 + 2 = a(-7/4 + 5)^2, or 12 = a(13/4)^2, or   1 = a(169/16).

Solving for a:  a = 16/169 = 0.09, or approx 16/160, or 1/10.  Unfortunately, this is not close to any of the four answer choices.

I thought it best to try again, and fortunately my second try was correct:

10+2 = a(13/4)^2, or  (169/16)a.  Thus, 12 = a(169/16)

                                   12
Solving for a:  a = ------------- = 1.14.  The answer choice closest to this is 1.
                                169/16

Answer A is correct.

Can someone please help me find the volume?
Mrac [35]

Answer:

C

Step-by-step explanation:

Volume = base * height.

The area of the base = base * height/2

That means the area of the triangular base is 8 * 5.1/2 = 20.4

The height is 9, so the volume is 20.4 * 9.

That means the volume is 183.6, which is C
