In the model below the anchor of a guy wire is 16 feet away from the telephone pole. John puts a 5 foot pole under the guy-wire parallel to the telephone pole (see image below). John knows the distance he put his pole from the anchor, which is labeled x John says he can use similar triangles to calculate the height of where the guy wire meets the telephone pole.
Do you agree with John's statement that he can prove similarity if we know side x? Provide mathematical justification

Select the correct answer. lisa and daisy work at a hair salon. the salon charges $18 for a hair styling session with lisa and $12 for a session with daisy. the income on a certain day is projected to be $216. this situation can be represented by the equation 18x + 12y = 216, where x is the number of lisa's customers and y is the number of daisy's customers. how many customers would lisa need to serve to attain the projected income if daisy calls in sick that day? (note: x ? 0, y ? 0, and x and y take only integer values.)
