I would say that it is the first one since it is for a mathematical notation
If the ratios form a proportion, the ratios will be equal. first we'll simplify the ratios:
14/21
divide top and bottom by 7
2/3
26/39
divide top and bottom by 13
2/3
ss you can see now, the ratios are indeed equal, so they do form a proportion
Given that the tornado traveled 260 miles in 4 hours, its initial speed is 65 mi/h. Then, slowing by 20% every hour, the speed after 2 hours can be calculated through the equation,
speed = (65 mi/h) x (1-0.2)^2
speed = 41.6 mi/h
Thus, the speed of the tornado after 2 hours is approximately 41.6 mi/h.
Answer:
(8,-2)
Step-by-step explanation:
270 counterclockwise is the same as 90 clockwise. Rotate on a graph.
