Answer:
Length of arc between two cars = 7 feet (Approx.)
Step-by-step explanation:
Given:
Radius of carinal wheel = 18 feet
Number of car equal distance = 16
Find:
Length of arc between two cars
Computation:
Angle between two cars = 360 / 16
Angle between two cars = 22.5°
Length of arc = [θ/360][2πr]
Length of arc between two cars = [22.5/360][(2)(3.14)(18)]
Length of arc between two cars = [0.0625][(6.28)(18)]
Length of arc between two cars = [0.0625][113.04]
Length of arc between two cars = 7.0625
Length of arc between two cars = 7 feet (Approx.)
The amount is $9,350 ,time in years: 4 and interest is 5 percent compounded semiannually.
Use the formula.
Here n =2 .
Substitute the values,
Hence the present value is 7673.98 dollar.
Since 2 inches = 6 ft and length of room in the place = 7 inches,
(2x3.5) inches = 6x3.5 ft
7 inches = 21ft
Actual Length of Room = 21 ft.
Width of Room in plane = 3 inches
(2x1.5) inches = 6 x 1.5 ft
= 9 ft
Actual Length of Rook = 9 ft.
Actual Area of Room = Actual Length of Room x Actual Width of Room = 21 x 9 = 189 ft^2
Answer:
79.605
Step-by-step explanation:
sin 31° = 41/x
x = 41/sin 31°
x = 79.605
A+b=180° because they are a linear pair
(2x+10)+(3x+20)=180
5x+30=180
5x=150
x=30
a=c because they are vertical angles
2(30)+10= C
60+10=C
70=C
