Answer:
Step-by-step explanation:
Let's say that the time it took him to get to work in the morning is t hours. Then the time it took him to get home in the afternoon must be 1 - t hours. We know that for any trip, distance equals rate times time or d = rt . That means that the distance he drove to work is given by , but we also know that the distance he drove to get home must be the same distance, because he took the same route (and, presumably, no one picked up him house and moved it while he was at work) so for the trip home we can say d = 30 × (1 - t) and since the distances are equal, we can say:
45t = 30 × (1 - t)
45t = 30 - 30t
45t + 30t = 30
75t = 30
t = 30/75
t = 2 /5 hour to drive to work at 45mph
Since , d = rt
d = 45 ×(2/5) = 18miles
It will be a reflex angle
A reflex angle is an angle that is more than 180° and less than 360°
Obtuse: More than 90° but Less than 180°
Acute: Less than 90°
Answer:
3.2w+3.6
Step-by-step explanation:
(−1.2)(−3)+(−1.2)(−w)+2w
=3.6+1.2w+2w
Combine Like Terms:
=3.6+1.2w+2w
=(1.2w+2w)+(3.6)
=3.2w+3.6
