Answer:
C. The equation x = 50y represents this situation.
Step-by-step explanation:
Let's examine each statement given and determine if it is correct or not correct based in the information given to in the graph.
Statement A: "The point (2, 100) means that there are 100 pounds of wild rice in 2 bags."
✅This is CORRECT because from the graph, on the x-axis (number of bags), when x = 2, y on the y-axis (pounds of wild rice) is 100.
Statement B: "The data represents a proportional relationship".
✅This is CORRECT because a graph that shows a proportional relationship between x and y, has a line that cuts through the point of origin (0, 0).
Statement C: "The equation x = 50y represents this situation".
❌This is NOT CORRECT. The equation does not represent a proportional relationship between x and y. The correct equation should be y = 50x. Where 50 is the constant of proportionality. That is y/x.
Statement D: "The constant of proportionality is 50."
✅this is CORRECT because constant of proportionality = y/x = 100/2 = 50.
They could be: 12:14, 18:21, 24:28
The answer it -2

The answer would be 7 1/2 because you would add 1 1/2, 2 1/2,3 1/2 so there you go
Answer:
It will be quadrupled
Step-by-step explanation:
we know that
All spheres are similar
so
The ratio of the surface areas of two spheres is equal to the scale factor squared
Let
z ----> the scale factor
x ----> surface area of the sphere with radius doubled
y ----> surface area of the original sphere
so
The scale factor is 2 (because the radius of the sphere will be doubled)
substitute
so
The new surface area is 4 times the original surface area
therefore
The surface area will be quadrupled
