Find the value of x. if necessary, round to the nearest tenth a=47sq in
kipiarov [429]

the picture in the attached figure


we know that

area of the triangle is equal to

A=(b*h)/2


in this problem

A=47 in²

b=x

h=x

so

47=x*x/2 \\  x^{2} =94 \\ x= \sqrt{94}  \\ x=9.69 in \\ x=9.7in

therefore

the answer is

x=9.7 in

Figure ABCD - Figure EFGH
Colt1911 [192]
<h3><u>Answer:</u></h3>
  • 30.5 units
<h3><u>Step-by-step explanation:</u></h3>

We know that:

  • <u>Trapezoid ABCD has one side that is 25 unit. </u>
  • <u>The other 3 sides (AB, BC, and CD) are 12 units. </u>
  • <u>EF = 6 units</u>
  • <u>EH = 12.5</u>
  • <u>Trapezoid ABCD is congruent to Trapezoid EFGH</u>

<em>If the 3 sides of the trapezoid ABCD are the same sides, then side EF, FG, GH must be of the same length because of congruence. The value of FG and GH must be the same length as EF. We can clearly see in the picture that EF is 6 units. Hence, EF is 6 units, FG is 6 units, and GH is 6 units. The work of the perimeter is shown below.</em>

<u>Work</u>

  • => 6(3) + 12.5
  • => 18 + 12.5
  • => <u>30.5 units</u>

Hence, the perimeter of EFGH is 30.5 units.

From the box plot, it can be seen that for grade 7 students,
The least value is 72 and the highest value is 91. The lower and the upper quartiles are 78 and 88 respectively while the median is 84.

Thus, interquatile range of <span>the resting pulse rate of grade 7 students is upper quatile - lower quartle = 88 - 78 = 10

</span>Similarly, from the box plot, it can be seen that for grade 8 students,
The least value is 76 and the highest value is 97. The lower and the upper quartiles are 85 and 94 respectively while the median is 89.

Thus, interquatile range of the resting pulse rate of grade 8 students is upper quatile - lower quartle = 94 - 85 = 9

The difference of the medians <span>of the resting pulse rate of grade 7 students and grade 8 students is 89 - 84 = 5

Therefore, t</span><span>he difference of the medians is about half of the interquartile range of either data set.</span>
