(a) Let <em>x</em> = 3.12333…. Then 100<em>x</em> = 312.333… and 1000<em>x</em> = 3123.333…, so that

1000<em>x</em> - 100<em>x</em> = 3123.333… - 312.333…

==>   900<em>x</em> = 2811

==>   <em>x</em> = 2811/900 = 937/300

(b) <em>x</em> = 4.38555…   ==>   100<em>x</em> = 438.555… and 1000<em>x</em> = 4385.555…

==>   900<em>x</em> = 3947

==>   <em>x</em> = 3947/900

(c) <em>x</em> = 37.222…   ==>   10<em>x</em> = 372.222…

==>   9<em>x</em> = 335

==>   <em>x</em> = 335/9

(d) <em>x</em> = 16.292929…   ==>   100<em>x</em> = 1629.292929…

==>   99<em>x</em> = 1613

==>   <em>x</em> = 1613/99

(e) <em>x</em> = 2.333…   ==>   10<em>x</em> = 23.333…

==>   9<em>x</em> = 21

==>   <em>x</em> = 21/9 = 7/3

kicyunya [14]

Answer:

B. take up less space than when the data set is not organized

Step-by-step explanation:

Well, in this question, you can analyze one answer after the other.

In A see important values in the data set, this makes sense when determining mode and median of a data set.Median is the center value in a data set, while mode is the repeated value in the set.When data set is arranged from smallest to the largest, the median and mode can be seen clearly.These can be the important values in the data set

In C. More easily see the maximum and minimum values in the data set, is possible especially when data is arranged in an increasing order.The smallest value will start, where as the largest value will be at the end.This applies to D too.

However in B, it will depend with the manner you would like to analyze the data.For example organizing data using tables will make your data easy to understand and present your analysis.Another person will group the data in intervals to identify the frequency of in data set.So, you see, its not about space taken by data but how you would like to present your data when analyzing it.

Hope this helps.

sattari [20]

Answer:

117

Step-by-step explanation:

Okay, the problem is asking that we find the hypotenuse of this triangle (AKA, the lake.)

a²+b²=c²

A= 75

B= 90

C is always the hypotenuse.

75²+90²= c²

5,625+8,100= 13,725

√13,725= 117.15374513859981591194584103639

To the nearest whole number: 117

To the nearest tenth: 117.2
