Question 1022512: It takes 645 pennies to reach one meter. There are 1,000mm in one meter. A penny is 1.55mm thick.
1.) If this pattern continues, in how many days will the stack of pennies be about 1 meter tall? I got this equation for it but I dont know how to solve it
:645 = 2^d (d representing days)
2.) The distance from the earth to the moon is 405,696,000 meters. About how many stacked pennies would it take to reach the moon?
3) After about how many days will the stack of pennies be tall enough to reach the moon?
Please help me and add the steps because I'm at a lost on how to solve these. Thank you! Also on some questions the tutors put the word "log" in front of numbers. If you do that can you please tell me what it symbolizes so I wont get confused please.
