5 0

Answer:

The formula is connecting R and A

 R = k \frac{1}{A}

The value of 'K' = 18.15

Step-by-step explanation:

<u><em>Step(i):-</em></u>

Given that R is inversely proportional to A

      R ∝ 1 / A

      R = k \frac{1}{A}

Given  R = 12 .1 and A = 1.5

       R = k \frac{1}{A}

       12.1 = K (\frac{1}{1.5} )

      K = 12.1 × 1.5

     K = 18.15

The value of 'K' = 18.15

JulijaS [17]

Barry found a computer at Staples for $989. A week later, the computer went on sale for $849. The percentage change is 14.156 % decrease

<em><u>Solution:</u></em>

Given that Barry found a computer at Staples for $989

A week later, the computer went on sale for $849

To find: percent of change

Percent change is the extent to which a variable gains or loses value. The figures are arrived at by comparing the initial (or before) and final (or after) quantities according to a specific formula.

<em><u>THE PERCENT CHANGE IS GIVEN AS:</u></em>

\text{ percent change } =\frac{\text { final value - initial value }}{\text { initial value }} \times 100

If the result is positive, it is percentage increase

If the result is negative, it is percentage decrease

Here initial value = 989 and final value = 849

Substituting the values in above formula,

\begin{aligned}&\text { percent change }=\frac{849-989}{989} \times 100\\\\&\text { percent change }=-0.14155 \times 100=-14.156 \%\end{aligned}

Here negative sign denotes percentage decrease

Thus percentage change is 14.156 % decrease
