Please help :((((((
Alik [6]

Answer: c)

Step-by-step explanation:

This can be done through trial-and-error. Use the pythagoreas' theorem a^{2} +b^{2} =c^{2} and if the left side of the equation is equal to the right, that is the answer.

(Do take note that c is the longest side.)

a)

0.07^{2} +2.4^{2} =5.7649

2.5^{2}=6.25

Since 2.5^{2} \neq 5.7649, a) is wrong.

b)

17^{2} +30^{2} =1189\\
34^{2} =1156

Since 34^{2}\neq1189, b) is wrong.

c) (answer)

5^{2} +12^{2} =169\\13^{2} =169

Since 13^{2} =169, c) is correct.

d)

(7x)^{2} +(12x)^{2} =193x^{2}\\(13x)^{2} =169x^{2}

Since (13x)^{2} \neq193x^{2}, d) is wrong.

Part A:

Electricity Company | Rate Charged | Rate Rounded |

    Atlas Energy                12.065                12.070

   Big City Light                 9.138                  9.140              

        Connex                      9.143                  9.140

  Dynamon Power            9.707                  9.710

       ElectriCo                    9.503                  9.500

Part B:

Big City Light and Connex.

Part C:

Two companies can have the same rate when they are rounded because two numbers can be rounded to the same number although they are different numbers. For example; 9.138 and 9.143 can both be rounded to 9.140.
