The constant of proportionality is the relationship between variables that are directly proportional
The constant of proportionality of 
is 45.2
The distance measured in miles is given as:
An equation that has a constant proportion is represented as:
Rewrite the equation in terms of d and t.
So, we have:
Where, k represents the proportionality constant.
By comparison:
Hence, the constant of proportionality is 45.2

I believe the answer is B. 24.36 Centimeters.
Answer:
34.98 square units.
Step-by-step explanation:
It is given that DEF is a triangle, EF=10, DF=7 and DE=12.
Information of sides of triangle is relevant to calculating area.
We should use Heron's formula.
According to Heron's formula, the area of triangle is
where,
For triangle DEF, let a=10, b=7 and c=12.
Now,
Area of triangle is
Therefore, the area of triangle DEF is 34.98 square units.
10 (2x + 3) = 15 x 9
20x + 30 = 135
20x = 135-30 = 105
x = 105 / 20 = 5.25
answer: x = 5.25
Answer:
w + d = 797
w = d - 53
Because they are equal, we can take whatever is on one side of the = and replace it for what's on the other side.
d - 53 + d = 797
2d = 850
d = 425
Step-by-step explanation:
