Answer:
3a. The polygon has 15 sides, so it is a pentadecagon or a 15-gon.
3b. Each interior angle measures 156°.
3c. The measure of an exterior angles is 24°
Step-by-step explanation:
3a
(n - 2)180 = 2340
n - 2 = 13
n = 15
The polygon has 15 sides, so it is a pentadecagon or a 15-gon.
3b
2340/15 = 156
Each interior angle measures 156°.
3c
There are 2 ways to calculate the measure of an exterior angle.
Method 1:
Each exterior angle is supplementary to its adjacent interior angle.
156 + x = 180
x = 24
Method 2:
The sum of the measures of the exterior angles of a polygon, 1 per vertex, is 360, no matter the number of sides.
360°/15 = 24°
The measure of an exterior angles is 24°
The running total is $95.27.
There are two types of records, Active and Inactive. There are also two major classifications, Vital and Important.
<h3>Why is record keeping important?</h3>
- In order to create reliable financial statements, you need good records. These consist of balance sheets and income (profit and loss) statements. These statements might assist you in managing your business and dealing with your bank or creditors.
He opened the account with $299.88. He subsequently wrote many cheques, from which you deduct the sum of 299,88.
He deposited a check, thus 299.88-90.48= 209.40, 209.40 - 65.00= 144.40, and then he added $381.33 to 144.40 to get 525.73.
then you need to deduct more since he wrote more checks.
Consequently, 525.73-54.47=471.26, and 471.26-375.99=95.27, giving him a balance of $95.27.
- Good Records entail documents comprising recorded data that show the efficacy of the quality management system, independent of the format or feature.

Y = 3...I believe in standard form, this would be written as : y = 0x + 3
y = an integer is a horizontal line...and if u have x = an integer, it would be a vertical line
266 tickets were the combined amount of adult and child tickets sold.
Step-by-step explanation:
Adult tickets sold = 152
Ratio of adult tickets to child tickets sold = 4:3
We need to find combined amount of adult and child tickets sold.
First finding child tickets sold making a proportion.
Let child tickets sold = x
4:3=152:x
Solving:
Cross multiplying:
Divide both sides by 4
So, the Child tickets sold are: 114
Combine amount of adult and child tickets sold = 152+114 = 266
So, 266 tickets were the combined amount of adult and child tickets sold.
