For his phone service, deon pays a monthly fee of $18
, and he pays an additional $0.04
per minute of use. the least he has been charged in a month is $61.28
.
what are the possible numbers of minutes he has used his phone in a month?
use m for the number of minutes, and solve your inequality for
m.

(61.28-18)/0.04= 1082 minutes.
So deon spends at least 1082 minutes on his phone.

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

7p=14 so then you would divide by p=2
