You have to do 3        2
                         ---  +  ---. You have to do 3 + 2 which is 5, and leave the 
                         8        8    denominators the same, so the answer is 5/8.

The denominator ( the bottom number in a fraction ) has to stay the same so you put the amount of Mary's pizza over 8 = 3/8

Now you do the same for the actor = 2/8

Now keep the denominator the same and add 2 and 3 to give you 5.

And thats your answer! = 5/8

The graph below shows the height of a tunnel f(x), in feet, depending on the distance from one side of the tunnel x, in feet:
denis23 [38]
Part A) x-intercepts simply show that when the value of the function is zero. Vertex coordinates show that when the function obtains its maximum value. When x=50, function obtains its maximum value and it's 75. The function is increasing in the interval (0, 50) and decreasing in the interval (50, 100). In regard to the height and distance of the tunnel, these numbers show that decreasing and increasing intervals are symmetric. Each number from the intervals has its own pair in the corresponding interval and they are located in the same distance from the midpoint (50,75)

Part B) In order to calculate the average rate of change, we can first write the function. Using the information about the x-intercept and the vertex coordinates, we find that our function is f(x)=-0.03x^{2}+3x.
Plugging 15 and 35 in x, we can find the values of the function, i.e. 
f(15)=38.25 and f(35)=68.25.
Then, the average change is \frac{68.25-38.25}{35-15}=1.5

How do i solve this​
Sophie [7]

Step-by-step explanation:

You're given that ΔUVW is similar to ΔYZW.  The tricky part is identifying which sides in ΔUVW correspond to which sides in ΔYZW.

The triangles share point W, so visually rotate one triangle around W until the two triangles align.  That way, you can see that UW and ZW correspond to each other, and VW and YW correspond to each other.

Now you can find the scale:

VW / YW = 5/12

And you can write a proportion to find x:

UW / ZW = VW / YW

x / 64 = 5 / 12

x = 26 ⅔
