A scale drawing of a rectangular stage uses a scale factor of 3 from the drawing to the actual stage. One side on the drawing is 6 inches and the adjacent side is 5 inches. What is the actual area represented by the rectangle?
Read the passage: In the greenhouse system, fish waste feeds bacteria that convert ammonia into nutrients plants can use. The plants then remove some dissolved nutrients before water returns to the tank. The system is efficient only when water temperature, oxygen, and feeding rates remain within a narrow range. Why does the author include the contrast in the final sentence?
Read the passage: When a city plants trees along streets, the benefits are not limited to shade. A block with mature trees can feel calmer, but the larger effect is practical: leaves slow rainwater, roots hold soil, and summer pavement temperatures fall. The challenge is that young trees need years of care before those benefits appear. Which statement best expresses the central idea of the passage?
Read the passage: Students placed temperature sensors at three points along a stream. The shaded upstream site changed little during the day, while the open site below the parking lot warmed quickly after noon. Their teacher warned that one warm afternoon could suggest a pattern, but a month of readings could support it. Which detail would be most important to include in a summary?
Read the passage: The boxes in the county archive looked ordinary until a student noticed labels written by three different clerks. Matching those labels to town records showed that the photographs had been reorganized after a flood. The discovery did not solve every mystery, but it changed which dates the researchers trusted. Which inference is best supported by the passage?
