Emily and Andy each go to a hardware store to buy wire.The table shows the relationship between the cost and the length of wire.

Lady_Fox [76]

Answer:

So, Emily will spend, 11.52 unit on wire

and, Andy will spend 18.72 unit on wire.

Step-by-step explanation:

Cost of wire is = $\frac {4.80}{120}$

= $\frac {5.40}{135}$

= $\frac {6.00}{150}$

= $\frac {7.00}{175}$

= 0.04 unit/inch

We know that,

12 inch = 1 foot and

1 yard = 3 foot [Note that unit of a quantity always denoted singular].

So, Emily will spend,

$24 \times 12 \times 0.04$ unit

= 11.52 unit on wire

and, Andy will spend,

$13 \times 3 \times 12 \times 0.04$ unit

= 18.72 unit on wire.

Is 12.89 irrational

STatiana [176]

No. It's the ratio of 1,289 to 100 .

Also, it can be written as a fraction with whole numbers
on top and bottom, like this: 1289 / 100 .

Also, it can be written down on paper completely, using
digits and a decimal point or fraction bar. (You did that.)

Any one of these three facts makes it a rational number.
