Thomas had 5/12 of a pie. his friend, Katelyn ate 1/6 of his pie. How much is left?
Answer:

Step-by-step explanation:
Let suppose that airliners travel at constant speed. The equations for travelled distance of each airplane with respect to origin are respectively:
First airplane

Where t is the time measured in hours.
Since north and west are perpendicular to each other, the staight distance between airliners can modelled by means of the Pythagorean Theorem:

Rate of change of such distance can be found by the deriving the expression in terms of time:

Where
and
, respectively. Distances of each airliner at 2:30 PM are:


The rate of change is:


19^2 + x^2 = 21^2
19^2 = 361
21^2= 441
361 + x^2 = 441
x^2 = 441-361 = 80
x = sqrt(80) = 8.944 round to nearest tenth = 8.9

Answer:
(- ∞ , 88)
Step-by-step explanation:
1) m - 88 < - 176
add 88 to both sides
2) m < -88
3) interval notation: ( - ∞, 88)
