Answer:

The first number is

72.6

Step-by-step explanation:

Let second number be x.

First number= 6x

Third number= 3x

According to question,

6x+x+3x=121

or, 10x=121

or,x=121/10=12.1

First number= 6x=6×12.1=72.6

Third number=3x=3×12.1=36.3

Suppose c is inversely proportional to the square of d. If c=6 when d=3⁢, find the constant of proportionality and write the for
NemiM [27]

Answer:

The constant of proportionality is 54.

k = 54

c as a function of d:

c(d) = \dfrac{54}{d^2}

c(7) = \dfrac{54}{49}

Step-by-step explanation:

We are given the following in the question:

c is inversely proportional to the square of d.

\Rightarrow c\propto \dfrac{1}{d^2}\\\\\Rightarrow c = \dfrac{k}{d^2}\\\\\text{where k is constant of proportionality}

When c = 6, d = 3.

Plugging the values, we get,

6 = \dfrac{k}{3^2}\\\\\Rightarrow k = 6\times 3^2 = 54

Thus, the constant of proportionality is 54.

c as a function of d can be written as:

c(d) = \dfrac{54}{d^2}

We have to find value of c when d = 7.

Putting values, we get,

c(7) = \dfrac{54}{(7)^2}=\dfrac{54}{49}

is the required value of c.
