Answer:
25
Step-by-step explanation:
625 = 11(d) + x(a)
625 = (11x25) + 14a
625 = 275 + 14a
350 = 14a
a = 350/14
a = 25
Therefore, 25 tickets were purchased ahead of time.
Answer:
ill talk
Step-by-step explanation:
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.

.....Jeremy did not make a good inference. The ratio is not in proportion to 2/15. The correct inference would be about 26 students who did not read any books in July. The sample might be biased since it was limited to those at the pool....
