Step-by-step explanation:

you can re-write 3 1/2 hours into minutes.

1 hr = 60 minutes,

Therefore:

3 1/2 hours = 3.5 times 60 = 210 minutes

So now we have the ratio:

3 1/2 hours : 36 minutes

210 minutes : 36 minutes

Both numbers can be divided by 6

210/6 = 35 and 36/6 = 6

So now we can re-write the ratio as :

35 : 6

Step-by-step explanation:

For this problem, we can simply plug in the coordinate point into the given formula.

(-8, 6) = (-8 + 5, 6 - 4)

(-8, 6) = (-3, 2)

So, A' is at point (-3, 2)

Now, we have to find the distance from A to A'. We can use the distance formula.

d=\sqrt{(x2-x1)^2+(y2-y1)^2}

d=\sqrt{(-3-(-8))^2+(2-6)^2}

d=\sqrt{(5)^2+(-4)^2}

d=\sqrt{25+16}

d=\sqrt{41}

So, the distance between A and A' is about 6.4 units.
