question 3: the city planner wants to know how much water pipe is used per street in her city. choose the correct inputs and action.
water pipe per street (ft/st)

Explanation:

Step1: Identify Q1 input & action

To get total electricity use (kw), multiply electricity use per house (kw/house) by number of houses (houses). The action is multiplication, which is "use conversion factor" here.
Inputs: electricity use per house (kw/house), number of houses (houses)
Action: use conversion factor

Step2: Note Q2 incomplete

Question 2 is cut off, so no valid inputs/action can be determined.

Step3: Identify Q3 logic (general)

To get water pipe per street (ft/st), we need water pipe per house (ft/house) and houses per street (houses/st), then multiply (use conversion factor).
Inputs: water pipe per house (ft/house), houses per street (houses/st)
Action: use conversion factor

Answer:

Question 1:

• Inputs: electricity use per house (kw/house), number of houses (houses)
• Action: use conversion factor

Question 2:

• Sorry, the question is incomplete and cannot be answered.

Question 3:

• Inputs (logical choices): water pipe per house (ft/house), houses per street (houses/st)
• Action: use conversion factor
