A chord consists of notes that sound good together. The C major chord, starting at middle C, has the following frequencies: C - 262 Hz
E - 330 Hz
G - 392 Hz

Determine the ratio of the frequency of E to C. Express the answer in a simple integer ratio. (Due to rounding the ratio will be approximate.) How many E waves will fit in the length of four C waves?

Acoffee shop orders at most $3,500 worth of coffee and tea. the shop needs to make a profit of at least $1,900 on the order. the possible combinations of coffee and tea for this order are given by this system of inequalities, where c = pounds of coffee and t = pounds of tea: 6c + 13t ≤ 3,500 3.50c + 4t ≥ 1,900 which graph's shaded region represents the possible combinations of coffee and tea for this order?
