A cell phone sends a 4-megabyte picture file at a rate of 0.2 megabytes per second. The amount
of data d that is waiting to be sent is a function of
timet. Time is measured in seconds and data
waiting to be sent is measured in megabytes.
Use the equation to complete the function table.
d = 4–0.4

Andy wants to find the distance d across a river. he located points as shown in the figure, then use similar triangles to find that d = 223.5 feet. how can you tell without calculating that he must be wrong? tell what you think he did wrong and correct his error. round your answer to the nearest tenth if necessary. andy must have used the wrong . the distance d is actually feet.
