Answer:

8 2/3 units.

Step-by-step explanation:

As bothe the circles and the arcs are congruent, the chords QR and LN are also congruent.

So LN = QR

x + 7 = 4x + 2

7 - 2 = 4x - x

3x = 5

x = 5/3.

Therefore the length of QR = 4x + 2

= 4(5/3) + 2

=  20/3 + 6/3

= 26/3

= 8 2/3 units.

Finke typing speed increased from 40 words per minute to 45 words per minute. What was the percent increase?
Kaylis [27]
In the given question, it is already disclosed that the typing speed of Finke has increased from 40 words per minute to 45 words per minute. Now we have to find the percentage increase in the speed of typing.
For this purpose we have to find the solution in the method described below.
Number of increase in words typed per minute = 45 -40
                                                                           = 5
Then Percentage increase in the speed of typing by Finke = (5/40) * 100
                                                                                              = (1/8) * 100
                                                                                               = 25/2
                                                                                               = 12.5
So the percentage increase in the typing speed of Finke is 12.5%. I hope this has answered your question and the description used to solve this problem is understandable.
