Answer:

7740 degrees.

Step-by-step explanation:

The sum of the exterior angles of all polygons add up to 360 degrees.

So the number of sides and the number of interior angles in this polygon = 360 / 8 = 45.

Each internal angle = 180 - 8 = 172 degrees, so the sum of all interior angles

= 172 * 45

= 7740 degrees,

Let h represent the number of hits that kyle gets in his last 10 bats of the season . Write a ratio that represents kyles battin

Soloha48 [4]

The ratio that represents Kyle's batting average at the end of the season is h:10

<h3>Mean or Average</h3>

Mean is defined as the sum of data to the total number of samples.

Given the following

Total number of hits = h
Number of bats in a season - 10

Using the formula:

Ratio of the mean = Total number of hits/Number of bats

Ratio of the mean = h/10

Hence the ratio that represents Kyle's batting average at the end of the season is h:10

What number must be added to the expression below to complete the square?

stiv31 [10]

D. 1/4

Explanation:

a perfect square is written in the form

$(x+a)^2 = x^2 + 2ax +a^2$ (1)

In our problem, we have this perfect square:

$x^2 - x + C$ (2)

with C being unknown. However, by comparing (1) and (2), we know that

$2a=-1$

So, we find

$a=-\frac{1}{2}$

and therefore, the missing term must be

$a^2 = \frac{1}{4}$

so the complete square is

$x^2 -x +\frac{1}{4}$
