In t minutes, t/20 of the pool is filled and t/30 of it is emptied.
t/20 - t/30 = 1
multiply both sides by LCM 60.
3t - 2t = 60
t = 60
The pool is filled in 60 minutes.
Answer:
d = 69° , e = 32° , f = 79°
Step-by-step explanation:
d and 69° are vertically opposite angles and are congruent , so
d = 69°
e and 32° are vertically opposite angles and are congruent , so
e = 32°
69° , e , f lie on a straight line and sum to 180° , that is
69° + 32° + f = 180°
101° + f = 180° ( subtract 101° from both sides )
f = 79°
Answer:
the slope is -1.5
Step-by-step explanation:
-3/2= -1.5 or - 1 1/2
You would need to distribute the parenthesis. so the equation will be 12r-12<-12+8r
