Could someone with number 2 a

Alona [7]

The sum of the interior angles of a polygon with $n$ sides is

$180(n-2)$

Since a pentagon has 5 sides, the sum of its interior angles is

$180(5-2) = 180 \cdot 3 = 540$

Since it is a regular pentagon, all sides and angles are the same, so one single angle measures

$\dfrac{540}{5} = 108$ degrees.

What is the median for the following scores for Mrs. Johnson's first test? 59, 22, 87, 44, 96, 38, 70, 85, 79

katrin2010 [14]

To work out the median, you need to numerically sort the data (because currently, it's unordered).

The ordered set of data is: 22, 38, 44, 59, 70, 79, 85, 87, 96

Now you just need to pick the middle value, which is 70:

(as you can see: 22, 38, 44, 59, 70, 79, 85, 87, 96)

Therefore, your answer is 70 :)

The area of a rectangle is 20 square inches. If the length is 4 inches less than 6 times the width, then find the dimensions of

Tpy6a [65]

Step-by-step explanation:

Let the width=x

Length =6x-4

As we know that in a rectangle

${\boxed{\sf Area=LB}}$

Substitute the values

$\hookrightarrow\sf x (6x-4)=20$

$\hookrightarrow\sf 6x^2-4x=20$

$\hookrightarrow\sf 6x^2-4x-20=0$

Here a=6, b=-4, c=-20.
use quadratic formula

$\hookrightarrow\sf x=\dfrac {1}{3}+\dfrac {1}{3}\sqrt {31} \quad or \quad \dfrac {1}{3}+\dfrac {-1}{3}\sqrt {31}$
