Answer:
Both chords and diameters have two endpoints on a circle. Diameters must intersect the center of a circle.
Step-by-step explanation:
2860 times .12 equals $343.20
1. H+S=40
2. 19H+25S=922
From 1,
19H+19S=760
Subtract this from 2 to eliminate H,
19H+25S-19H-19S=922-760
6S=162
Solve for S, then use either equation to solve for H.
