Which of these non-terminating decimals can be converted into a ratinaol number

madreJ [45]

Answer

A. O.8743874374387438743....

Step by step explanation

Let's take a = O.8743874374387438743....

10a = 8.743874374387438743....

Similiarly,

10000a = 8743.874374387438743....

Since four decimal places are repeating.

Now subtract a from 10000a

10000 a - a = 8743.874374387438743.... - O.8743874374387438743....

9999 a = 8743

a = 8743/9999

8743/9999 = O.8743874374387438743....

That's it.

Hope you will understand the concept.

Thank you.

Tracy has a cell phone plan that provides 250 free minutes each month for a flat rate of $29.

natali 33 [55]

Answer:

250 minutes with the flat rate of $29.

$x\leq 250$

x would be the number of minutes called.

$x-250$

Tracy would be charged by $0.35 per minute.

$f(x)=29\\ 0\leq x\leq 250$

$f(x)=0.35(x-250)+29,\\250\leq x\leq ∞$
