Answer:
plane = 250mi/hr
wind = 5mi/minute
Step-by-step explanation:
speed = distance/time
plane = 1000miles/4hour
wind = 1000miles/200minutes
Use two unit fractions to convert this measurement.
4.6 mm to km
Answer:
0.0000046
Step-by-step explanation:
Intersecting secant angles theorem: The angle between two secants is half the difference of the intersected arcs.
52 = ½ (x − 38)
x = 142
Arc angles add up to 360.
360 = 80 + 38 + z + x
z = 100
Tangent-chord theorem: The angle between a tangent and a chord is half the intercepted arc angle.
y = x/2
y = 71
1. When a number is added to it's opposite it cancels itself out or in other words combines to make zero.
