Construct a parallelogram abcd such that ab=9 cm, bc=6cm and abc=115 degress. (1) measure and write down the length of the diagonal bd (2) construct the perpendicular bisector of ab such that it cuts cd. measure and write down the length of at, such that t is the point where the perpendicular bisector of ab cuts cd

Acoffee shop orders at most $3,500 worth of coffee and tea. the shop needs to make a profit of at least $1,900 on the order. the possible combinations of coffee and tea for this order are given by this system of inequalities, where c = pounds of coffee and t = pounds of tea: 6c + 13t ≤ 3,500 3.50c + 4t ≥ 1,900 which graph's shaded region represents the possible combinations of coffee and tea for this order?
