that would be four hours.
12x3=36
1 hour 20 minutes x3= 4 hours
To convert from radians to degrees multiply by 180 / π, So:-
3 π / 5 = 180 * 3 * π / 5π
= 540 / 5
= 108 degrees answer
Answer:
A. y=-1/3x+10
Step-by-step explanation:
Perpendicular gradients(slopes) are negative reciprocals so
m=-1/3 then use the point (6,8) to find the equation of the line
y=mx+b
8=(-1/3)(6)+b
8=-2+b
b=10
y=-1/3x+10
