Answer:4320cm
Step-by-step explanation:
(length of the arc)/(length of the radius)=central angle
lengthof the arc/20=216
lengthof the arc=216×20
length of the arc=4320cm
I believe the slopes represent how far each car can go in x number of hours
I plugged the equation in to my graphing calculator and found the zeros at (-2.7,0) and (2.7,0)
If you would like to know what is y when x = 42, you can calculate this using the following steps:
x = 8 ... y = 20
x = 42 ... y = ?
8 * y = 20 * 42 /8
y = 20 * 42 / 8
y = 105
The correct result would be: y = 105 when x = 42.
Answer:
x=30°
Step-by-step explanation:
total angles on a straight line=180°
4x+2x=180°
6x=180°
x=180°/6
:.x=30°.
