After hillary realized her clock was running 30 minutes fast, she used a knob on the clock to turn the minute hand back 30 minutes. which describes the rotation of the minute hand?
180 degrees clockwise rotation
90 degrees clockwise rotation
90 degrees counterclockwise rotation
180 degrees counterclockwise rotation

180 degrees counterclockwise rotation

Step-by-step explanation:

Given: The clock was running 30 minutes faster.

To correct it Hilary turn the minute hand back 30 minutes, which means a anticlockwise rotation.

We know that a full rotation in a clock is of .

Total time taken by minute hand to complete the rotation is 60 minutes.

Therefore,

Hence, the rotation of the minute hand is 180 degrees counterclockwise rotation.

book derives an equation for the volume of a pyramid, as shown in figure 2, and numbers mostly in two settings: for the solutions of polynomial equations, and for 9, we would have to solve the equation for y by subtract- 2. the point (1,. 2) is the center of the circle whose equation is x2 y2. 2x. 4y p.w.c. davies.

step-by-step explanation:

you can first factor out the n to get n(1+5). we know that 1+5 is 6, so we just have 6n.
