It will move it from one section to another and make the x axis 4 units more to the right
Answer:
central angle ( θ) = 1.91875radians
central angle ( θ) in degrees = 109.92degree
Step-by-step explanation:
Given:
diameter of 320 millimeters
Then the Radius of the circular
brake drum can be calculated as
Radius =Diameter/2
Radius = 320 millimeters/ 2
Radius= 160 millimeters
central angle ( θ) = arc/r
central angle ( θ) = 307 millimeters /160 millimeters
central angle ( θ) = 1.91875radians
Than to convert it to degrees we have
1rad × 180/π = degree
Where π =3.142
central angle ( θ) = 1.91875radians * 180/π
Therefore,central angle ( θ) in degrees = 109.92degree
Answer:
234 students and 151 family members
Step-by-step explanation:
Let x be the amount of students and y be the amount of family members...
x+y=385
x=y+83
We can solve using substitution...
y+83+y=385
Combine like terms
2y+83=385
Subtract 83 from both sides
2y=302
Divide both sides by 2
y=151
x=151+83
x=234
There were 234 students and 151 family members.
