Answer:
2340 degrees.
Step-by-step explanation:
The sum of the interior angle measures of any polygon can be calculated using the following expression ([tex]n[/tex] is the number of sides the polygon has):
[tex]180(n-2)[/tex]
For a 15-sided polygon, plug in 15 for n and simplify:
[tex]180(15-2)=180(13)[/tex]
Multiply to solve:
[tex]180(13)=2340[/tex]
For a 15-sided polygon, the sum of the interior angles must be 2340 degrees. You can go a step further and divide 2340 by 15 to figure out the individual measure of each interior angle (156 degrees).
The sum of the interior angles of a fifteen-sided polygon is 2340°.
What is the formula for interior angle of a regular polygon?The formula for calculating the sum of interior angles is (n-2)×180° where is the number of sides. All the interior angles in a regular polygon are equal. The formula for calculating the size of an interior angle is: interior angle of a polygon = sum of interior angles ÷ number of sides.
Given that, a fifteen-sided polygon.
Now, the sum of the interior angle measures is
(15-2)×180°
= 13×180°
= 2340°
Therefore, the sum of the interior angle measures is 2340°.

Answer:
B
Step-by-step explanation:
0.25 = 1/4 = 5/20
0.35 = 35/100 = 7/20
5/20 + 7/20 = 12/20 = 6/10 = 3/5
Answer:
Step-by-step explanation:
so first you would do 0.25+0.35= 0.6
now put 0.6 into a fraction= 6/10 because 6 is in the 10th place then simplify 6/10=3/5 which to find that you divide each side by 2

Answer and Step-by-step explanation:
You're told to find the ordered pair of point E.
E is found on the y-axis.
If you count upwards 8 units, you will see that point E is there.
So, Point E is at the coordinate (0, 8), where 0 represents 0 units on the x axis, and 8 represents 8 units up on the y axis.

Answer:
0. 42
Step-by-step explanation:
any number greater than 0 is significant if it's exactly 0 or less than 0 is not significant. since it's two significant figures you count the first two numbers greater than 0 which is 0.41 and we have 8 will is greater than 5 which will be rounded to 1 then rounded to 0.41 which makes it 0.42

A garden table and a bench cost S585 combined. The garden table costs S65 less than the bench. What is the cost of the bench?
Answer:
Bench costs $325
Step-by-step explanation:
Try setting up an equation
x = cost of garden table
y = cost of bench
equation 1: x + y = 585
We also know that the table costs 65 dollars less than the bench.
cost of garden table = bench - 65
or
equation 2: x = y - 65
Now just substitute equation 2 into equation 1
(y-65) + y = 585
and solve for y
2y-65 = 585
2y = 585 + 65 = 650
y = 325 = cost of bench
