Determine the unit rate of a marathon runner who travels 15/2 miles in 1/4 hour

He that is measured at 220° is a reflex angle. the opposite angle is obtuse. find the measure of obtuse .

The actual length of side t is 0.045cm. use the scale drawing to find the actual side length of w

Simplify the rational expression. state any restrictions on the variable. t^2-4t-12 / t-8 the / is a fraction sign.
