Onvert the angle to decimal degrees and round to the nearest hundredth of a degree. 1315’36’’

The notation used is 1315 minutes and 36 secs. There are 60 minutes in 1 degree So in 1315 minutes we have X degrees So X * 60 = 1315 * 1 X = 21.916 degrees Also there are (60*60) seconds in 1 degree In 36 seconds we have X degrees. Hence X * 3600 = 36 * 1 X = 36/3600 = 0.01 degrees. So we have 21.916 + 0.01 = 21.926 degrees. But Suppose the question meant to write 13°15'36" instead if 1315'36" Then to calculate the decimal degrees, we follow the same method like the one above. So we have 13 + (15/60) + (36/60) = 13 + 0.25 + 0.6 = 13 85

the law of definite proportions states samples of a compound will always contain the same proportion of elements by mass. in other words, a given compound will always contain the same elements in the same proportions by mass.the law of multiple proportions states when two elements combine with each other to form more than one compound, then the weights of one element that combine with a fixed weight of the other are in a ratio of small whole numbers.
