Help fastttt please!!!!! When making a pie chart for this data, what percentage of the dresses would the sector label "Blue" inc

lbvjy [14]

Answer:

14%

Step-by-step explanation:

First find the total for all the dresses.

Total = 14 + 37 + 22 + 56 + 33

Total = 162

Now you are concerned about the blue dresses.

% = (22 / 162) * 100 = 13.58 %

Rounded to the nearest % it would be 14%

The number of degrees it would occupy in the pie chart would be 360 * 14/100 = 49 degrees.

What is this problem simplified

Svetlanka [38]

$\frac{x^2 - 5x-6}{x^2 - 36}$

You can begin to simplify this by factoring both the numerator and denominator:

$\frac{x^2 - 5x-6}{x^2 - 36} = \frac{(x-6)(x+1)}{(x-6)(x+6)}$

Next, cancel out any common factors in both the numerator and denominator:

$\frac{(x-6)(x+1)}{(x-6)(x+6)} = \frac{x+1}{x+6}$

Your answer would be $\frac{x+1}{x+6}$ .
