1. Determine the number of significant figures for thefollowing:

A) 4778526

B) 0.075

C) 850

D) 14268.5

E) 25.8 x 10⁵

F) 3310 x 10^-1

2) Convert the following into scientific notation:

A) 0.004288

B) 4200

C) 363000000

D) 0.00000363

Please use these conversion for the following problems:

1mi = 1609m              3.79 L = 1.00gal          1.00 mi = 1.61 km

1 foot = 12inches         1m/s = 2.2mi/hr           1 inch = 2.45 cm = 25.4mm

3) Express 18 mi/h in units of meters per second. (1 mi = 1609m)

4) Convert 775,632 seconds into days

5) Convert 42 miles into feet

6) Your car gets 22.6 mi/gal on a vacation trip in the U.S. Ifyou were figuring your mileage in Europe, how many km/L did itget?

A) The displacement is either greater than or equal to thedistance traveled.

B) The displacement is always equal to the distancetraveled.

C) The displacement is either less than or equal to the distancetraveled.

D) The displacement can be either greater than, smaller than, orequal to the distance traveled.
