Awindow is shaped like a parallelogram. the base is 16 inches long. the area is 608 square inches. what is the height of the window?

38 because you take the area A and divide it by the base B and you get your answer for height H. H=A/B or A=HB. 

1. 0.3 •4 is the same as 4 groups of 0.32. 7•0.8 is the same as 7 groups of 0.83. it increases by 0.5 every time, so 0.5x4 it increases by 0.9 every time, so 0.9x5. 0.9•12=10.86. 0.47•5=2.35i can finish the next ones in a separate post
