There are 15 non fiction books and 37 fiction books in the teacher’s collection. Which of the following expresses the ratio of f
2 answers:
To simplify a ratio, first make into the fraction form. a:b = 
Then find the prime factors of both the numerator and denominator.
Now cancel out any common factors. But if there isn't any common factors, then the fraction or ratio is in its simplest formula.
And that is the case here.
And because the question wants the answer in ratio form, make the fraction back into a ratio.
So, A. 15:37 is the answer.

Check the picture below.
keeping in mind that the point of tangency for a radius line and a tangent is alway a right-angle, since the "red" chord is parallel to the "green" tangent line outside, then the chord is cutting the "green" radius there in two equal halves at a right-angle, as you see in the picture.
we know the chord is 10 units long, so 5 + 5, since is perpendicularity with the radius will also cut the chord in two equal halves.
anyhow, all that said, we end up with triangle you see on the right-hand-side, and then we can just use the pythagorean theorem.

Answer:
5 units
Step-by-step explanation:
The distance from a point (m, n ) to the line Ax + By + C = 0 is given by
d =
For the point (- 1, 3 ) , with m = - 1 and n = 3
3x - 4y = 10 ( subtract 10 from both sides )
3x - 4y - 10 = 0
with A = 3 , B = - 4 , C = - 10
d =
=
=
=
= 5
