What is the y-coordinate of the midpoint of WU?<br> A 2.5<br> B. -1.5<br> C. -0.5<br> D. 1.5
lilavasa [31]

Option C: -0.5 is the right answer

Step-by-step explanation:

Given is the graph on which different points are indicated.

We have to find the y-coordinae of the mid-point of WU.

The formula for mid-point is:

(\frac{x_1+x_2}{2} , \frac{y_1+y_2}{2})

So we only have to know the y-coordinates of both points to find the mid-points y coordinate

So by observing the graph we get

y_1 =0

y_2 = -1

So,

\frac{0-1}{2}\\= \frac{-1}{2}\\= -0.5

Hence,

Option C: -0.5 is the right answer

Emily thinks the perfect tomato sauce has 8 cloves of garlic in every 500{ mL} of sauce. Raphael's tomato sauce has 12 cloves of
igomit [66]

For perfect solution we need to have :-  8 colves   in 500ml    solution

500   ml     has   8 cloves

1 ml             has     8 / 500 cloves

100ml         has   8 / 500  * 100  =    8/5  = 1.6 cloves

Raphael's mixture  

    900 ml  has 12 cloves

      1 ml     has   12 / 900 cloves

   100 ml has   12 / 900 *  100   =    12 / 9  =   1.33 cloves

so concentration of garlic in 100 ml solution of Raphael's solution is less than Emily's solution    so it is not garlicky enough.     ( option B)
