Answer:
108°
Step-by-step explanation:
Suppose that circle with center A is a circular arena. Points B, C, D, E and F are 5 lights. These 5 points form regular pentagon (because these 5 lights are equally spaced around the perimeter of the arena).
The sum of all interior angles of pentagon can be calculated using following formula
All interior angles in regular pentagon are of equal measure, so
Thus, the measure of each angle formed by the lights on the perimeter is 108°.
Answer:
4
Step-by-step explanation:
The perimeter of the region is equal to the sum of the perimeter of the four semicircular arc. Since the semicircular arcs have the same measure, therefore:
Perimeter of region = 4 × Perimeter of semicircular arc.
The side of the square = diameter of the semicircle = 2/π.
The radius of semicircle = diameter/2 =
The perimeter of a semicircle = perimeter of a circle ÷ 2
Answer:
Explanation:
First, I plotted both the lines on the graph, then I graphed the inequality.<u> </u><em>Please check out image.</em> Looking at the image, we can tell that the graph matches with Graph-C. Hence, Option C is correct.
Hoped this helped!
Step-by-step explanation:
The price of car purchased 5 years ago = 15000
The price of car sold = 7000
By compound depreciation,
... (1)
where Pn = 7000
P = 15000
R = rate of interest to be calculated
T = 5 ( number of years)
substituting the values in equation (1), we get
0.858 is rounded off as 0.86
R/100 = 0.14
By simplifying the above equation, we get
Rate of depreciation = 14%
