The Richter scale is used for measuring the magnitude of an earthquake.
The Richter magnitude is given R = 0.67log(0.37E) + 1.46 where E is the
energy (in kilowatt hours) released by the earthquake. If an earthquake
release 15,500,000,000 kilowatt hours of energy, what is the earthquake's
magnitude?

Juliana says that she can use the patterns of equivalent ratios in the multiplication table below to write an infinite number of ratios that are equivalent to 6: 10. which statement explains whether juliana is correct? she is correct because she can multiply 6 and 10 by any number to form an equivalent ratio. she is correct because 6: 10 can be written as 1: 2 and there are an infinite number of ratios for 1: 2. she is not correct because the multiplication table does not include multiples of 10. she is not correct because 6: 10 is equivalent to 3: 5 and there are only 9 ratios in the multiplication table that are equivalent to 3: 5.
