The Addition Property of Equality justifies Emily's first step. She added 9 to both sides, canceling out the minus 9 while keeping the equation equal.
For this question, this might help.
17.47 degrees is 17 + 0.47 degrees
If you are using minutes instead of decimal degrees, multiply the fraction by 60. So,
0.47 degrees * 60 minutes per degree= 28.2 minutes
Now you have 17 degrees 28.2 minutes
but you can replace fractions of a minute with seconds
0.2 minutes * 60 seconds per minute= 12 seconds
So the answer for
17.47º is equal to 17º 28' 12".
I hope this helps.
Answer:
Increased.
Step-by-step explanation:
In March 2007, the unemployment rate was 4.4 percent. In August 2008 was 6.1 percent. We need to remember that the unemployment rate equals the number of unemployed people divided by the people in the labor force.
Now, if we consider that the labor force remained constant during this period of time (according to the problem) then this would mean that the number of unemployed people actually increased during this period of 17 months.
