Answer:
7
Step-by-step explanation:
number of diagonals in a regular polygon = number of sides - 2.
A nonagon is a polygon having 9 sides.
Total number of diagonals in a regular nonagon
= 9 - 2
= 7
Answer:
Step-by-step explanation:
Given
<em>Decimal Grid = Hundredths</em>
To solve for each:
We have:
For Amber:
For Grace:
This means that Grace shaded 60 of the hundredth models.
Decimal shaded is:
For Marsha:
Multiply this by 100, to get the number of shaded
This means that Marsha shaded 170 of the hundredth models.
Decimal shaded is:
Answer:
13.3 ft
Step-by-step explanation:
24² - 20² = d²
d = √(576 - 400) = √176 = 13.26649... ≈ 13.3 ft.
We have the following equation:
2 (x-3) ^ 2 + 10 = 82
We must clear x.
We pass the constant terms to one side of the equation:
2 (x-3) ^ 2 = 82 - 10
2 (x-3) ^ 2 = 72
(x-3) ^ 2 = 72/2
(x-3) ^ 2 = 36
Square root to both members:
x-3 = +/- root (36)
x-3 = +/- 6
The solutions are:
x1 = 6 + 3 = 9
x2 = -6 + 3 = -3
Answer:
x1 = 9
x2 = -3
