The answer is 4/15. 3 is the same as 3/1 and when dividing you just invert the second fraction then multiply, so you would take 4/5 / 3/1 and make it 4/5 x 1/3. Which turns out to be 4/15.
Does this help.

Well if that's a division symbol then it's 4/5 x 1/3=4/15.
If it's addition it's 19/5

A circle has its center at the origin, and (5, -12) is a point on the circle. How long is the radius of the circle?

Amanda [17]

Option C

The radius of circle is 13 units

Solution:

The equation of circle is given by formula:

$(x-h)^2+(y-k)^2 = r^2$

Where, the center being at the point (h, k) and the radius being "r"

Given that circle has its center at the origin

(h, k) = (0, 0)

(5, -12) is a point on the circle

(x, y) = (5, 12)

Substituting in equation we get,

$(5-0)^2+(12-0)^2 = r^2\\\\5^2+12^2 = r^2\\\\r^2 = 5^2+12^2\\\\r^2 = 25 + 144\\\\r^2 = 169\\\\Taking\ square\ root\ on\ both\ sides\\\\r = \sqrt{169}\\\\r = \pm 13\\\\Since\ radius\ cannot\ be\ negative\ ignore\ r = -13\\\\Thus\ the\ solution\ is:\\\\ \r = 13$

Thus radius of circle is 13 units
