The roof lines of a building can be described by the system of equations below, where the floor is represented by the x-axis and the y-axis and the height of the building is along the z-axis. measurements are in feet. find the point of intersection of the roof lines, using an ordered triple in the form (x, y, z).

{ x+y+z=52,
3x-2y+z=69,
-x+2y-z=-59}

also part 2:
a support column will be placed under the intersection point. the column must be feet to reach from the floor to the intersection point.
someone me ?

i think is 3 and 6. this took me 10 min to think.hope to and hope that my answer is brainliest.(follow me )

d. millimeters per hour.

step-by-step explanation:

we are given that,

carlo used a rain gauge to measure the amount of water his lawn is receiving from the sprinklers.

since, according to the options, we see that,

water cannot be measured by 'miles per hour', 'meters per second' and 'grams per seconds'.

we get that, the water can be measured by 'millimeters per hour'.

hence, the appropriate rate for describing the amount of water is 'millimeters per hour'.
