You have been cleaning diesel dispensers for 35 minutes. you have completed 6 dispensers. how many minutes has it taken you to clean 1 dispenser? *

6 dispensers within 35 minutes can be shown in a rate of change:

This shows 6 dispensers per 35 minutes.
To find how many minutes it takes for one dispenser, we can divide the numerator and denominator by 6 in order to find the rate of change per one dispenser. The numerator is simplified to one, while the denominator is 35/6.
35/6≈5.8. This means that 1 dispenser takes 5.8 minutes to clean.

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
