Power usage is measured in kilowatt-hours, kWh. After 7 a. m., the power usage on a college campus increases at a rate of 21% per hour. Prior to 7 a. m., 15,040 kWh have been used. The university has a daily goal to keep their power usage less than or equal to 100,000 kWh. Which inequality can be used to determine the number of hours, t, after 7 a. m. when the power usage on campus will be less than or equal to 100,000?

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.
