Which expression shows the area of the shaded part of the grid? A hundred grid model showing a 7 4 array shaded blue. A. 0.04 ×

aksik [14]

Answer:

$C.\ Area = 0.4 * 0.7$

Step-by-step explanation:

See attachment for grid

From the attachment:

There are 10 cells on the horizontal axis and there are also 10 cells on the vertical axis.

This implies that, the measurement of each cell is:

$Each\ Cell = \frac{10}{10 * 10}$

$Each\ Cell = \frac{1}{10}$

$Each\ Cell = 0.10$

The horizontal axis has 7 selected cells.

This measures

$Horizontal = 7 * 0.10 = 0.70$

The vertical axis has 4 selected cells.

This measures

$Vertical = 4 * 0.10 = 0.40$

So, the selected area is:

$Area = Vertical * Horizontal$

$Area = 0.40 * 0.70$

$Area = 0.4 * 0.7$

Pls pls help for math

yan [13]

Answer and Step-by-step explanation:

The answer would be D. 82%.

All we need to do is add together the amount that can swim.

We do this because all of the numbers added together equals 1, so the parts that are split off represent the percentages (in decimal form) of the total amount of people.

0.34 + 0.48 = 0.82.

Multiply by 100 and we get 82%.
