Which statement best explains whether △pqr is congruent to △xyz? △pqr is congruent to △xyz because △pqr can be mapped to △xyz by a rotation of 180° about the origin. △pqr is congruent to △xyz because △pqr can be mapped to △xyz by a translation 5 units down followed by a reflection across the y-axis. △pqr is not congruent to △xyz because there is no sequence of rigid motions that maps △pqr to △xyz. △pqr is congruent to △xyz because △pqr can be mapped to △xyz by a reflection across the y-axis followed by a reflection across the x-axis.

An airplane consumes fuel at a constant rate while flying through clear skies, and it consumes fuel at a rate of 64 gallons per minute while flying through rain clouds. let c represent the number of minutes the plane can fly through clear skies and r represent the number of minutes the plane can fly through rain clouds without consuming all of its fuel. 56c+64r < 900056c+64r< 9000 according to the inequality, at what rate does the airplane consume fuel while flying through clear skies, and how much fuel does it have before takeoff? the airplane consumes fuel at a rate of gallons per minute while flying through clear skies, and it has gallons of fuel before takeoff. does the airplane have enough fuel to fly for 60 minutes through clear skies and 90 minutes through rain clouds?

1. a parachutist is 800 feet above the ground when she opens her parachute. she then falls at a constant rate of 5 feet per second. select the equation that represents this situation. h = -800t + 5 y = -5x + 800 h = 5t - 800 y = 800x + 5 i need
