Answer:
60
Step-by-step explanation:
100 x 0.4 = 40 and that is the discount so you subtract that off the price so 100 - 40 = 60
To find the area of a regular figure,the formula would be:
s^2(n)/4tan (180/n)
where
s is the length of any side
n is the number of sides
In this case:
12^2(6)/4tan (180/6)
=144/4tan(30)
=144/120tan
≈374.1 in^2 (correct to the nearest tenth)
Hope it helps!
Answer:
292.45 m
Step-by-step explanation:
Both disk are at an angle of 38.48°
From the image below we calculate as,
For disk B, direct distance is 1.296 km from receiver = 1296 m
Vertical height from ground will be = 1296 x sin38.48 = 806.42 m
For disk A, direct distance is 826 m from receiver
Verival height above ground = 826 x sin38.48 = 513.97 m
Difference in height between disks is 806.42 - 513.97 = 292.45 m
I hope this helps you

Answer:
The diameter is 1 unit
Step-by-step explanation:
The circumference is 3.14 units
C = pi * d
Using 3.14 for pi
3.14 = 3.14 d
Divide each side by 3.14
3.14/3.14 = 3.14 d/ 3.14
1 =d
