PLEASE HELP

Determine the area of the figure shown above

The number of revolutions of two pulleys is inversely proportional to their diameters. if a 24-inch diameter pulley making 400 revolutions per minute is belted to an 8-inch diameter pulley, find the number of revolutions per minute of the smaller pulley.

How can the correlation in the scatter plot graph below best be described? positive correlation negative correlation both positive and negative no correlation

Give me the equations of two lines that have the same slope but are not parallel.
