Step-by-step explanation:
Let consider that object is regular prism. The height in feet is obtained by dividing the volume by the area of the base:
Answer:
Step-by-step explanation:
The time (minutes) vary directly with the number of walls and inversely to the number of people.
m = kw/p, where m = minutes, w = walls, and p = people
60 = 5k/7
420 = 5k
84 = k
m = 10(84)/10
m = 84

<span>If
two equations have different slopes but equivalent y-intercepts, they
will have one solution and that will be the point where the y-intercept
is. If two equations have different slopes and different y-intercepts,
then there will be one solution where those two lines meet. If two
equations have the same slope but different y-intercepts, the lines will
be parallel, and there is no possible intersection point. And if two
equations have equal slopes and equal y-intercepts, these lines will
have an infinite amount of solutions, because if the equations are one
the same line, every single point on that line is a solution to the
system. </span>
