Approximately how much of a degree is 10 seconds?

0.0028

Step-by-step explanation:

60 minutes in 1 degree, so 1/60 = 0.01666666667

there are 60 seconds in 1 minute and 1 minute is 0.01666666667 of a degree

so  0.01666666667 divided by 60 x 10 or 0.01666666667 divided by 6 is .0028

answer set (b) 0.5, 3/4 80% is in order from least to greatest.  

step-by-step explanation:

in order to compare rational numbers to each other, it is much easier if they are in the same form.   typically, the best form in which to evaluate rational numbers is in decimals.   in order to convert a percent to a decimal, you would divide the given percentage by 100.   you can also accomplish the conversion by moving the decimal point over two places to the left.   for example, the decimal value of 80% is 80/100, or 0.8.   in order to convert a fraction to a decimal, you need to divide the numerator by the denominator.   for example, 3/4 is 0.75.   so, for choice (b) 0.5 3/4 (0.75), 80% (0.8) is the only choice in which the numbers are in order from least to greatest.  

your answer would be 12
