Answer:
5
Step-by-step explanation:
given that x and y are proportional, they can be expressed as y = rx, where r is the proportionality constant. Thus, we can solve for r by doing y/x in any given point.

Answer:

Step-by-step explanation:
we know that
If CD is parallel to XZ
then
Triangle XYZ is similar to Triangle YCD
therefore
The ratio of their corresponding sides are equal

we have
CX=5\ units, CY=25\ units, YD=20\ units,




substitute the values

Answer:
3
Step-by-step explanation:
Okay, I'm going to skim this down mentally as I type. He has who know how many cubes with a height of 2 inches. The situation does NOT mention the length and their CUBEs so obviously, the dimensions are 2x2x2 making the area 8. He uses 60 inches of foil to wrap all but ONE FACE. This detail makes the question harder. 60 divided by 8? is 7.5. so that strategy wont work. 60 divided by 2 i dunno if that's the answer. so deep thinking goes into the rest of this situation. we dont know the area of each face yet.. so if we make the cube into a square, it would be 2x2 making each face with an area of 4. if he wrapped all but ONE. a cube has 6 faces so 4x5 for each cube wrapped! 4x5= 20. 60 divided by 20 = how many cubes!!! .. the answer is 3!
