Answer:

In B)  y = x/7 , the constant of proportionality is 7.

Step-by-step explanation:

Two quantities X and Y are said to be in proportion if and only if

X = kY   or, \frac{X}{Y}  = k,

where k =  Proportionality Constant.

Here, 7 is the constant of proportionality. Then,

A .   y = 14x

here, \frac{y}{x}  = 14  ≠ 7

B .   y = x/7

here, \frac{x}{y}  = 7  = constant of proportionality .

C.   y = x

here, \frac{y}{x}  = 1  ≠ 7

What's the error? Jerry says that a cube with edges that measure 10 cm has a volume that is twice as much as a cube with sides t
disa [49]
The quick way to dispute something like this is to simply do the calculation and then create a ratio. 

Cube One (Large Cube)
The formula for a cube is V = e^3 
e = the measurement of an edge. In this case.
e = 10 cm
V = e^3
V = 10^3 = 10*10*10
V = 1000 cm^3

Cube 2 (Small Cube)
V = e^3
e = 5 cm
V = 5*5*5
V = 125 cm^3

Ratio
Large Cube / Small Cube = 1000 / 125 = 8/1.

The difference in size is 8 to 1 not 2 to 1.

Explanation
He's right if he sticks to one side. The ratio of one side of the large cube to the small one is 2 to 1. But once you put that into the formula for volume, three sides are multiplied together and that 2 shows up everytime you multiply the sides together.
