1. A four-sided pyramid has a height of 36 meters. The base is square with sides of length and width equal to 30 meters. What is the volume of the pyramid? The volume of a four sided pyramid is:

Volume = _______________________

2. The time t for a golf ball to fall is: If the golf ball falls for 0.8 seconds, how far will it fall?	distance d = ___________

3. Using the equation in question two, how long would it take a golf ball to fall 35 meters?

time t = ___________

4. The same pyramid as in question one is seen in the drawing. The base is a square with a length of 30 meters, as seen from above in the lower diagram. Use Pythagoras theorem that a² + b² = c² to determine the length of the hypotenuse of the base h.

h = ________________

5. Divide h by two: h/2 = ___________

6. The value h/2 is the base leg of the right triangle with a height leg of 36 meters. Use these two values to calculate k. k = ________

7. Calculate my speed on Thursday evening at the state track running in lane two:

speed = = ___________

8. What is the probability of rolling a five on a six-sided die? _______________

9. What is the probability of rolling an odd number on a ten-sided die numbered from 0 to 9 inclusive? _______________________

10. A step-up transformer has a 20:12 voltage step-up ratio. Express 20:12 as a fraction, simplifying and reducing as appropriate. ________________
