Question

1.The approximate distance of the moon from Earth is 4 x 10^5 km and the average approximate distance from the Earth to Venus is 4 x 10^7 km. How much farther is Venus from Earth than the moon?
A) 10 times farther
B) 100 times farther
C) 1000 times farther

2. Compare 6 x 10^5 and 3 x 10^4.
A) 6 x 10^5 is 20 times larger than 3 x 10^4
B) 6 x 10^5 is 15 times larger than 3 x 10^4
C) 6 x 10^5 is 10 times larger larger than 3 x 10^4

2 Answer

  • For number 1, the answer would be B, because 10^5 is 100,000 and 10^7 is 10,000,000, and if you divide 10,000,000 by 100,000, your answer is 100.

    For number 2, your answer would be A, because 100,000÷10,000 is 10, and 6÷3 is 2.  Then, you multiply 10x2 to get 20 as your answer.
  • Answer:

    B

    Step-by-step explanation: 4 x 105 is 400,000 and 4 x 107 is 40,000,000, so Venus is 100 times farther from Earth than the moon.
