What is the value of the expression modeled by the decimal grids?

The value of the expression modeled by the decimal grids is 4.13

Step-by-step explanation:

Question is incomplete (the decimal grids are missing; see attachment for complete question).

Few points to be noted when reading a decimal grid are.

1. The scale of the grid

2. The ratio of the shaded region to the whole region

3. A fully shaded grid represent 1.

The scale of the grids in this question is a 10 x 10 grid.

10 * 10 = 100

Meaning that there are 100 squares in a grid

Having said this, well proceed to getting the decimal value of each individual grids.

For grids before the addition sign (+)

The first grid is fully shaded; so, it'll be represented with 1

The second grid is also fully shaded; thus, it'll also be represented with 1

The third grid has some of its region shaded; 23 of the 100 squares are shaded.

So, the third grid = 23/100 = 0.23

The Summation of the grids before the addition is 1 + 1 + 0.23 = 2.23

We move to the grids after the addition sign.

The first grid is fully shaded; so, it'll be represented with 1.

The second grid has some of its region shaded; 90 of the 100 squares are shaded.

So, the second grid = 90/100 = 0.90

The Summation of the grids after the addition sign is 1 + 0.90 = 1.90

Now, we can properly represent the grids in decimal forms.

This will be represented as

2.23 + 1.90

And that's equal to

4.13

Hence, the value of the expression modeled by the decimal grids is 4.13

noncoplanar points are points that do not lie on the same line.

answer: h=5.6 i don't really know how to put into words, so i though i would let you do that. i hope i was able to some

step-by-step explanation:

18 = 6(h)+1/2

18 = 6h+1/2

18-1 = 6h/2

17 = 3h

17/3 = h

h = 5.6
