Using the formula r=d/t where d is the distance in miles, r is the rate and t is the time in hours at which rate must you travel to cover 337.5 miles in 4.5 hours? a-55mphb-65mphc-75mphd-85mph

337.5 is the distance (d) and 4.5 is the time (t)
to find r it is d/t, so 337.5÷4.5 is 75mph so the answer is c

Answercounterclockwise rotation about the origin by 180 degrees followed by reflection about the y-axisexplanationthe given figure has verticesrecall that for counterclockwise rotation about the origin, when we rotate figure pqrs counterclockwise through an angle of 180° about the origin, the coordinates will becomenext, we reflect in the y-axis by negating the x-coordinates of the resulting figure to obtain,therefore the correct answer is c
