ben deposited $500 into a savings account at a local bank that earned 5one_half_small. gif% interest per year. how much interest does he earn per year?

Which of the following is an example of an opposing signal? no examplthates given.   i would say, that traffic lights in a city at major intersections direct the flow of traffic in opposite directions so would be an example.also, stop signs on either side of the same street would be an example. at a train crossing, the light for allowing car traffic in opposite directions or not would be another example.

The angle measures would be 70 and 90
