Answer:
Then, the area is 222,48 in
Step-by-step explanation:
The area of the regular polygon is: 1/2 x perimeter x apothem.
The perimeter 6 times the number of sides of the polygon which is 9*6in = 54 in.
The apothem is: s/2tan(180/n) where "s" is the lenght of the side and "n" the number of sides.
apothem = s/2tan(180/n) = 6in/(2tan(180/9)) = 8.24 in
Then, the area is: 1/2 x 54 in x 8.24 in = 222,48 in
Answer:
16
Step-by-step explanation:
First of all, I think it was "respectively", not "respecfully", =))). A noticeable point.
From the problem, three item's costs are represented by three consecutive even integer.
Thus, we can call cost of spoiler is x, sunroof is x-2, stereo is x + 2. It is conditioned that x is an even number.
Since the sum of the three is 48, we have
(x-2) + x + (x+2) = 48
x+x+x -2 +2 = 48
3x =48
x=16
So the spoiler is 16; thus, the sunroof is 14 and the stereo is 18

Step-by-step explanation:
Answer:
The expression used to find the change in temperature per hour is Algebraic expression
Thus per hour; the temperature falls at the rate of 
Step-by-step explanation:
A temperature falls from 0 to 
in 
Which expression finds the change in temperature per hour.
From the above given information;
The initial temperature is 0
The final temperature is
The change in temperature is 
Thus;
-12.25 ° = 3.5 hours
To find the change in x° per hour; we have;
x° = 1 hour
The expression used to find the change in temperature per hour is Algebraic expression
From above if we cross multiply ; we have;
(- 12.25° × 1 hour) = (x° × 3.5 hour)
Divide both sides by 3.5 hours; we have:
x° = - 3.5
x° = 
Thus per hour; the temperature falls at the rate of
Area of the shaded part is given by:
A=(area of the sector)-(area of triangle)
A=(θ/360πr²)-(1/2sinθab)
A=(120/360*π*6²)-(0.5*6²*sin120)
A=12π-15.59
A=22.1 cm²
Answer: A=22.1 cm²
