He should use a 3x3 grid, so 9 squares in total. Mark should then shade in 6 of those 9 boxes. 6/9 = 2/3. He would have shaded in 66.666666% roughly.

Answer:

66 + 1 ( not fully shaded ) squares will be shaded.

66.67% region will be shaded

Step-by-step explanation:

It is given that Marks uses a grid to model percent equivalent of \frac{2}{3}.

Let us assume that Mark uses a model containing 100 grids.

Now, as the grids are divided into region equivalent to \frac{2}{3} i.e. it is divided into 3 parts.

Moreover, 2 out of those 3 parts will be shaded.

As, \frac{2}{3} =0.6667

i.e. \frac{2}{3}=66.67%

So, it gives us that 66 squares in the grid will be fully shaded and one will not be fully shaded.

Hence, 66 + 1 ( not fully shaded ) squares will be shaded and in percent, 66.67% of the region will be shaded.

Plssss help in need of answers soon
vfiekz [6]
My guess is that you're doing the Law of Cosines? You have everything you need for that except the angle theta, which is the thing you need to find.  It's set up like this: (8)^2 = (10)^2 + (5)^2 -[2(10)(5)cos A]  I used A instead of theta. Doing that math, you have: 64 = 100 + 25 -[ 100 cos A]; 64 = 125 - 100 cos A;
-61 = - 100 cos A; -61 / -100 = cos A; .61 = cos A. Now use your inverse function on your calculator to find cos^-1(.61) and that equals 52.4
