Distance = rate * time
t = d / r
t = 91 / 14 = 6.5 hrs
plus 2 hour rest stop
8.5 hrs
start at 7 AM
end at 3:30 PM
Answer:
9
-3x-12
9+6x-7-9x-5
(Group liked terms)
9+6x-9x-7-5
( subtract the numbers ) -7-5= -12
9+6x-9x-12
( add similar elements ) 6x-9x=-3x
9-3x-12

Answer:
19
Step-by-step explanation:
9+10=19
Answer:
the slope is -3, the slope is negative, the y-intercept is 0
Step-by-step explanation:
this ones are the ones that apply to the graph
We just use the sinus rule to calculate this
a / sin alpha = b / sin beta
Alpha is the 90 degree angle from the wall to the floor
beta is the angle from the top of the ladder to the wall,
wich is 90 degrees - 75 degrees (triangle has 180 degrees angles, one is 90 degrees), so beta = 15 degrees
14 foot / sin 90 = b / sin 15
sin 90 = 1
we move the sin15 over to the other side
14 foot x sin 15 = b
b = 3.62 foot
