How long would it take for your account to have $1000, if your principle amount was $500 at an annual interest rate of 7% compounded.

=10.24

Step-by-step explanation:

500(1+0.07)^x = 1000

divide both sides by 500

(500(1+0.07)^x)/500 = 1000/500

(1+0.07)^x = 2

1.07^x = 2

convert your it to log format:

x = log(107/100)2

x = 10.24

30 miles

step-by-step explanation:

we know that 60 seconds equals 1 minute and 60 minutes 1 hour

44 ft       60 sec     60 min     158400   ft

  *   *   =

1 sec       1 min       1 hour         hour

we know that there are 5280 ft per mile

158400   ft       1 mile         30 miles

  *   =

1   hour               5280 ft     1 hour

so in 1 hour   it can travel 30 miles
