If the volume of a room is 792 ms and the area of the floor is 132 m2, find the height of the room

the height of the room = 6 meters

Step-by-step explanation:

volume of cuboid = area × height

so,=》 792 = 132 × height

=》height = 792 / 132

=》height = 6 meters

the equation of the parallel line would be y = 2x + 9

step-by-step explanation:

to start we need to find the slope of the original line. we can do that by looking at the coefficient of x, which is 2

since the slope of the original line is 2 and parallel lines have the same slope, we know the new line will also have 2 slope. now we can use that along with the point given in point-slope form to get the find equation.

y - y1 = m(x - x1)

y - 5 = 2(x + 2)

y - 5 = 2x + 4

y = 2x + 9

so mark-up is 0.4 multiplied by 180 = 72
