Taylor's 7th Blog Review

REVIEW TIME!!!

This is on the last part of my notes from section 7.1.

Now lets learn how to get minutes and seconds from our equations.

ab.cd
.cd x 60 = y minutes y'
y x60 = z seconds z''

This is the formula that we will be using in the following problem.

Covert 18.488 degrees to minutes and seconds.

.488 x 60= 29.28 First we will put .488 into the equation because it is after the decimal point. We will then multiply it by 60 so that we can get 29.28 . Since we have another decimal point we must continue the equation.

.28 x 60= 16.8 We will take the numbers after the decimal and multiply them by 60. Since we don't need the .8 you will simply drop it, since we just need seconds.

18 degrees 29' 16'' This is what your answer should be and what it should look like.

The final thing that you must know is how to convert the minutes and seconds back into degrees. You will use the following formula in order to do this.

x'=minutes y''= seconds

x/60 + y/3600= degrees

Now use it to solve the following problem.

Convert 28 degrees 54' 22'' in to degrees.

54/60 + 22/3600 First place the seconds and minutes in their appropriate location in the formula.

.906 Then you add the fractions together and convert the fraction that you may have gotten if you are doing this by hand into a decimal.

28.906 degrees Than you simply place the decimal behind the number and that is how you get your answer.

That is all the notes from the last part of section 7.1. Until my next blog BYE.
