<h2>Answer:</h2>

The percentage of the dresses would the sector labeled "Red" include is:

                A.  9%                        

<h2>Step-by-step explanation:</h2>

Color            Frequency  

Red                   14

Black                37

Blue                  22

White                56

Other                33

Total                162

The percentage of the dresses that would include the sector labeled Red is:

          \dfrac{Frequency\ of\ red}{Total}\times 100\\\\i.e.\\\\=\dfrac{14}{162}\times 100\\\\\\\\=8.642\%

<em>which on rounding to the nearest percent is:</em>

<em>            9%</em>

<em>Hence, the correct answer is: Option: A</em>

Sum=14 + 37 + 22 + 56 + 33 = 152 => 100%
red = 14 => x%

100% / 152 = x / 14
x = 100 × 14 / 152
x = 1400 / 152
x = 9,21% = 9%

A model ship has a mast that is 7 inches tall. A right triangular sail goes from the top of the mast to 1 inch from the bottom o
dezoksy [38]

Answer:

12 square inches.

Step-by-step explanation:

Please consider the complete question.

A model ship has a mast that is 7 inches tall. A right triangular sail goes from the top of the mast to 1 inch from the bottom of the mast. The length of the base of the sail is 4 inches. The height of the sail is along the mast. Find the area of the sail.

The sail will form a right triangle with respect to mast, whose height is 6 inches and base is 4 inches as shown in the diagram.

The area of the sail will be equal to area of triangle.

\text{Area of triangle}=\frac{1}{2}(\text{Base}\times\text{Height})

\text{Area of triangle}=\frac{1}{2}(4\text{ in}\times6 \text{in})

\text{Area of triangle}=2\text{ in}\times 6 \text{in})

\text{Area of triangle}=12 \text{ in}^2

Therefore, the area of the sail is 12 square inches.

Please answer thank you

-x - 9 \geq 5

You want to get x by itself.

First subtract 9 from both sides of the equation.

-x - 9 \geq 5
    +9                 +9

-x \geq 14

Then divide -1 on both sides.

-x/-1 \geq 14/-1

I'm pretty sure when you divide a negative number when solving inequalities, you switch the sign.

x \leq 5
