Answer:
The area of regular polygon with 9 sides is 405 square inches.
Step-by-step explanation:
Given
Perimeter of Polygon = P = 135 inches
Apothem = a = 6 inches
We know that the sides of regular polygon are equal. Let s be the side of the polygon then
[tex]P = 9*s\\135 = 9*s\\s = \frac{135}{9}\\s = 15\ inches[/tex]
Now the formula for area of polygon when apothem, sides and number of sides is known:
[tex]A = \frac{a*n*s}{2}\\A = \frac{6*9*15}{2}\\A=\frac{810}{2}\\A = 405\ in^2[/tex]
Also the formula can be written as:
[tex]A = \frac{1}{2}P*a[/tex]
Hence,
The area of regular polygon with 9 sides is 405 square inches.

someone helpppp pleaseeee
Answer:
138
Step-by-step explanation:
G + H = 180 {G, H are linear pair}
12x + 6 + 4x - 2 = 180
12x + 4x + 6 - 2 = 180
16x + 4 = 180
16x = 180 - 4
16x = 176
x = 176/16
x = 11
G = 12x + 6
= 12*11 + 6
= 132 + 6
= 138

If the Miami Marlins won 14 of their first 27 games and the team continued to win at the
same rate, how many games would they win in a 162-game season?
c. 98 games
d. 56 games
a. 84 games
b. 70 games
This type of problem can be solved in various ways such as in terms of ratios and fractions, Let us go with fractions.
What is a fraction?A fraction is written in the form of p/q, where q ≠ 0.
Fractions are of two types they are proper fractions in which the numerator is smaller than the denominator and improper fractions where the numerator is greater than the denominator.
Given, Miami Marlins won 14 of their first 27 games.
So, their win rate in decimal is,
= 14/27.
= 0.518.
∴ In 162 games at the same rate, Miami Marlins will win,
162×0.518.
= 84 games.
So, after playing 162 games they'll win 84games.

A varies inversely as the square of B. If A is 1 when B is 3, find A when B is 5
Answer:
0.36
Step-by-step explanation:
A= K/B^2
K= A × B^2
K= 1 × 3^2
K= 1×9
K= 9
Therefore if B is 5 then A can be calculated as follows.
K= A × B^2
9= A × 5^2
9= A × 25
9= 25A
A= 9/25
A= 0.36
Hence A is 0.36
find the measure of BE step by step
Answer:
BE = 49 cm
Step-by-step explanation:
Use Pythagorean theorem
(hypotenuse)² = (base)² + (leg)²
ΔDEF,
DE² + EF² = FD²
DE² + 63² = 65²
DE² + 3969 = 4225
DE² = 4225 - 3969
DE² = 256
DE = √256 = √(16*16)
DE = 16 cm
ΔCBD,
BC² + BD² = CD²
56² +BD² = 65²
3136 + BD² = 4225
BD² = 4225 - 3136
BD² = 1089
BD = √1089 = √(33*33)
BD = 33 cm
BE = BD + DE
= 33 + 16
BE = 49 cm
