An apprentice productively working a 40-hour week earns more wages and is worth considerably more to the local union and the industry than one who works only 30 hours per week. consider two apprentices, a and b, working the same job at the same scale. apprentice a works 40 hours and is paid $160.00 from which $4.80 is paid to the local union. apprentice b only works 30 hours. how much will the local union receive in dues for the 30 hours work?

$3.60

You can get this by determining that the rate of which they are paid is $4 an hour (divide the total by the amount of hours). Then you can find the rate of which they collect dues by dividing the amount they paid by their total (3%). 

Using those numbers you can find the total amount the second person paid. 

50 % is the answer !

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
