Answer:

The answer to your question is:

Step-by-step explanation:

1.-

Data

3.3 x 10 ⁴ pounds of paper

1.5 x 10³ pounds of aluminum

Amount of aluminum / amount of paper = 1.5 x 10³ / 3.3 x 10⁴

                                                                  = 0.045 times

                                                                 = 4.5 x 10 ⁻²

2.-

Data

1.2 x 10 ³ text messages in a month

text messages in a year = ?

                  1.2 x 10³ text messages -------------------  1 month

                     x                                   -------------------  12 months

                    x = (12 x 1.2 x 10³) / 1

                    x = 14400 text messages

                   x = 1.44 x 10⁴ text messages

3.-

Data

distance = 4 x 10⁶ miles I am not sure if the power is 6 or 8

speed = 1.6 x 10³ mi/h

Formula

              time = distance / speed

              time = 4 x 10⁶ / 1.6 x 10³

              time = 2500 h

              time = 2.5 x 10 ³ h
