Mary made $176 for 8 hours of work. At the same rate, how much would she make for 17 hours of work?

Mary’s rate: $176/8hrs = $22per hr

To put this in another way, for every hour Mary works, she will be making $22.

To find out how much money she will earn working 17 hrs we need to multiply.

17hrs * $22 = $374

16 minutes is correct

Okay so for every triangle has three angles that always add up to 180 degrees. and to tell the difference between whether they are secure, right or obtuse is that acute: has one angle that is less than 90 degrees. right triangle means there is at least one angle that is exactly 90 degrees. and an obtuse angle has an angle that is bigger than 180 degrees. i’ll do #13 as an example: 13. 40 and 50 so if every triangle has 180 degrees 40+50= 90 degrees then180-90= 90 degrees so the third angle is 90 degrees and because this triangle has a 90 degree angle it means it is a right triangle
