Answer:
5/2 inches
Step-by-step explanation:
If there is 25/4 squared inches, we could set this as an equation:
Now, since 25 and 4 is a perfect square, we could do this:
(distribute the square exponent to both 5 and 2 to get the original)
And since the exponent is the same, we can clearly tell x is 5/2 (or square root it)
Answer:
A
Step-by-step explanation:
Answer:
The constant of proportionality is:
Step-by-step explanation:
We know that when y varies directly with x, we get
y ∝ x
y = kx
k = y/x
where 'k' is called the constant of proportionality
From the graph, it is clear that the point (2/5, 1/2) passes through the line which represents the direct relationship.
so we have the point (2/5, 1/2), and
x = 2/5
y = 1/2
so substituting x = 2/5 and y = 1/2 in the equation
k = y/x
k = [1/2] / [2/5]
k = [1 × 5 ] / [2 × 2 ]
k = 5/4
Therefore, the constant of proportionality is:
Answer:
D: 18
Step-by-step explanation:
Answer:
When a relationship is proportional, all y over x ratios simplify to the slope of the line which is the constant of proportionality or the unit rate, with one as a denominator. Example: Consider the equation y = 60x. The slope is 60. The rate of change is 60 units for every one unit.
