Emerson has 25 homework questions for math. He has already completed 19 of the questions. What percentage
represents the number of homework questions that Emerson
has already completed?

76%

The fraction of questions Emerson has completed is 19/25. To convert this to a percentage, we want to write this as something divided by 100. To do so, multiply the numerator and denominator by 4, to get the fraction 76/100. Therefore, Emerson has completed 76% of the homework questions.

If you have access to a calculator, a more efficient way to solve such a question would be to convert 19/25 to a decimal (it is equal to 0.76), and multiply by 100 to get 76%.

ca = ec

cpctc makes it so that corresponding parts of the triangle you proved to be equal are equal, the other options aren't part of the part of the triangles you proved to be equal.

the degrees would remain the same ( the number to the left of the decimal point.

the multiply the decimal by 60 to get the minutes and use the numbers to the left of the decimal point.

then multiply the decimal portion of that by 60 for the seconds and round off as needed.

39 .956652

the 39 remains the degrees.

the minutes = 0.956652 x 60 = 57.39912

the minutes = 57

the seconds = 0.39912 x 60 = 23.95 = 24 ( rounded to nearest tenth)

so 39.956652 = 39 degrees, 57 minutes and 24 seconds

-75.159809

the -75 remains the degrees

the minutes = 0.159809 x 60 = 9.58854

the minutes = 9

the seconds = 0.58854 x 60 = 35.31, rounded to nearest tenth = 35.3 seconds

so -75.159809 = -75 degrees, 9 minutes and 35.3 seconds.

the first coordinate is north or south, since it it positive it is north.

the second number is east or west, because it is negative it is west.

39 degrees, 57 minutes and 24 seconds n
