I don't know how to explain it, but
the answer is 302.24
Known facts:
A line shaft rotating at 250 rpm, a grinder shaft that turns at 1200 rpm diameter of grinder pulley is 5 inches.
1. Proportion equation
350/1200 = 5/x
2. Cross multiply
1200*5=250*x
x=(1200*5)/250 = (24*50*5)/(5*50) = 24
The big wheel diameter is 24 inches
D) (8, 10) because with a radius of units, anything with a y value higher than 8 is outside the circle
Answer:
m∠BOC = 53°
Step-by-step explanation:
The definition of an angle bisector is that it divides an angle into two congruent angles. ∠AOC is divided by angle bisector OB into angles ∠AOB and ∠BOC, hence those two angles are congruent.
m∠AOB = m∠BOC = 53°
