13 3/4 = ((13x4)+3)/4 = 55/4
1 2/3 = ((1x3)+2)/3 = 5/3
55/4 / 5/3
(55x3)/(5x4)
165/20
33/4
8 1/4
Answer:
The circumference is pi times larger than the diameter of a circle.
Step-by-step explanation:
The formula of the circumference of a circle is
C = 2(pi)r = (pi)d
C = (pi)d
To find the ratio of the circumference to the diameter, divide both sides of the equation by d.
C/d = pi
The circumference is pi times larger than the diameter of a circle.
The formula for reflecting preimages about the y-axis is (-x,y). This means that you would have to switch the x-coordinate's sign on each of the coordinates. So the coordinates would be W(-2,2), X(-4,3), Y(-5,2), and Z(-4,1). Now you have to translate the image. Translating it 3 units to the right would make you add 3 to each of the coordinates. The coordinates are now W(1,2), X(-1,3), Y(-2,2), and Z(-1,1). Now, I don't know if you meant that the y-coordinate is translated up or down 4 units, so I'll do both. For up, you would add 4 to each of the y-coordinates, and the new points would be W(1,6), X(-1,7), Y(-2,6), and Z(-1,5). For down, you would have to subtract 4 from each of the y-coordinates. The coordinates would be W(1,-2), X(-1,-1), Y(-2,-2), and Z(-4,-3). Those are your possible answers. I hope this helps.

Answer:
1 1/4 miles
Step-by-step explanation:
I don't know a proper equation but here is how I solved it. 1/2 is 2/4 so I added a fourth of that 2/4 to the mile he ran before he twisted his ankle so 1/4 +3/4 = 4/4 or 1 mile. So then adding what's left of the 2/4, you have 1 1/4 = d.
Let me know if I'm wrong
