A student made a model of a building. The model was 3 feet high and 10 feet wide. If the actual building is 700 feet wide, how tall is the building?​

210 feet
First you set up a porportion if you know the height of the model is 3 feet and the width is 10 feet then you can set up a porportion for the actual building in the same order. 3/10=x/700. Then you cross multiply

Ifound this on google “that means that the graph of a function with direct variation has these features: it is a straight line: because the slope is the ratio y/x = k. it passes through the origin (0,0): because y = kx = k (0) = 0.” i hope this you for what your looking for
