Please find the exact length of the midsegment of trapezoid JKLM with vertices J(6, 10), K(10, 6), L(8, 2), and M(2, 2). Thank y
I am Lyosha [343]

Answer:

the exact length of the midsegment of trapezoid JKLM  = \mathbf{ = 3 \sqrt{5} } i.e 6.708 units on the graph

Step-by-step explanation:

From the diagram attached below; we can see a graphical representation showing the mid-segment of the trapezoid JKLM. The mid-segment is located at the line parallel to the sides of the trapezoid. However; these mid-segments are X and Y found on the line JK and LM respectively from the graph.

Using the expression for midpoints between two points to determine the exact length of the mid-segment ; we have:

\mathbf{ YX = \sqrt{(x_2-x_1)^2+(y_2-y_1)^2} }

\mathbf{ YX = \sqrt{(8-5)^2+(8-2)^2} }

\mathbf{ YX = \sqrt{(3)^2+(6)^2} }

\mathbf{ YX = \sqrt{9+36} }

\mathbf{ YX = \sqrt{45} }

\mathbf{ YX = \sqrt{9*5} }

\mathbf{ YX = 3 \sqrt{5} }

Thus; the exact length of the midsegment of trapezoid JKLM  = \mathbf{ = 3 \sqrt{5} } i.e 6.708 units on the graph

Use compatible numbers to solve the problem 488 ÷ 62.A. 450 ÷ 50 = 9B. 434 ÷ 62 = 7C. 490 ÷ 70 = 7D. 480 ÷ 60 = 8
ipn [44]

Option D is correct. The required compatible number is 480 ÷ 60 = 8

Compatible numbers are numbers that have a close approximate to a given value

Given the expression  488 ÷ 62

The compatible number for 488 is 480

The compatible number for 62 is 60

Using these compatible numbers to solve the expression will give:

488 ÷ 62

= 480 ÷ 60

= 480/60

= 48/6

= 8

Hence the correct option will be 480 ÷ 60 = 8
