A designer is planning a larger ramp, △PQR △PQR , with the same incline of 30° and a height of 10 meters. In the diagram, △PQR △PQR is a dilation of △PST △PST with scale factor 2. What is the length, PS PS , of the smaller ramp?

Acable company claims that the average household pays $78 a month for a basic cable plan, but it could differ by as much as $20. write an absolute value inequality to determine the range of basic cable plan costs with this cable company. a. |x − 78| ≥ 20 b. |x − 20| ≥ 78 c. |x − 20| ≤ 78 d. |x − 78| ≤ 20
