Answer:
1
Step-by-step explanation:
10 = 4x+6
-4x = -10+6
-4x = -4
x = -4/-4
x = 4/4
x = 1
If the diameter is 1/2 mile, that is 0.5 mile, then the radius is 0.25 -half of it!
the angular speed is theta/time, which means
w=theta/time
but another formula for it is Velocity*radians
w=velocity*radians
velocity is 180 mph and radians are (revolution/2

radius), that is:
w=180*(1/2

*0.25)
and if we calculate this, we have: w=114.59, which is the correct answer!
1.99p = x
x = total cost
1.99p = 1.99 per pound of grapes.
Answer:
0.015 km/s
Step-by-step explanation:
40 km/hr
0.015 km/s
0.015 ÷ (1/3600)
0.015 × 3600
= 54 km/hr
