A grid of a hundred square show 7 shaded squares what decimal number is represented​
Tems11 [23]

Answer:

0.07

Step-by-step explanation:

From the question, a given grid was divided into a definite number of squares with some of the squares shaded.

Total number of squares in the grid = 100

number of shaded squares in the grid = 7

Thus, 7 squares are shaded out of 100 square in the grid.

So that this can be expressed in fraction as;

\frac{number of shaded squares}{total number of squares} = \frac{7}{100}

                                = 0.07

The decimal number of the squares represented is 0.07.

22^2 + 15^2 = c^2

"C", which is the hypotenuse, is approximately 26.63 inches long. So, now add all the sides, and you should have 63.63 inches as your final answer.

So the answer is going to depend on multiply 6x together with 9

(6x +  __ ) ( x  + 9)

Now what goes were the underline is?  

You have 54x. You need but 1 more to get 55x. So a one must go where the underline is.
