Answer:
Price and quantity supplied
Explanation:
The supply curve is a graphic representation of the relationship between the cost of a good and the quantity supplied of this good for a particular time period. Therefore, two factors that are displayed in the supply curve are the price and quantity supplied. The supply curve changes when these factors change too. Normally, as the price of a commodity increases, the quantity supplied increases too (all else being equal). However, changes in production can cause the curve to move left and right. Similarly, changes in price can cause the graph to shift as well.
Ronald Reagan was elected president in 1981.
It is the League of Nations
Answer:
The contour interval is 15 meters.
Explanation:
A is not correct because if that was the case we would have had much more contour lines, and if the starting point is 15 meters then 5 contour intervals up would have been an elevation of 40 meters, not 90.
B is not correct because is that was the case we wouldn't have had a contour line of 15 meters, as all contour lines would have been tens, like 10, 20, 30, etc.
C is correct because the elevation distance between the contour line of 15 meters and one of 90 meters is 75 meters, and if we divided that by five (the number of contour lines from one to another marking) we get a value of 15 meters.
D is not correct because just as with the interval of 10, there wouldn't have been a contour line 15, but they would have been 20, 40, 60, etc.
