He variable z is directly proportional to x, and inversely proportional to y. when x is 5 and y is 19, z has the value 2.8947368421053. what is the value of z when x = 12, and y = 24

Given Z is directly proportional to X and inversely proportional to Y.

This means that

Z=kX/Y where k is a yet-unknown constant.

We are also given that, when X=5, y=19, Z=2.8947368421053, this means

2.8947368421053=k(5/19)

or

k=2.8947368421053*19/5

=11.0000000000001

=>

Z=11.000000000000*X/Y

If X=12, Y=24, then

Z=11.000000000000*X/Y

=11.000000000000*12/24

=5.500000000000

answer: yard ramps with a level off platform are typically 36 feet long. truck, rather than at an angle, enabling access to those pallets at the very back of the truck. if you are using your yard ramp to convert a loading dock into a drive-in door, we even at 60 inches (5 feet) high and a 30 foot ramp, the slope of the ramp will be less
