Jen recently rode her bicycle to visit her friend who lives 12 miles away. on her way there, her average speed was 7 miles per hour faster than on her way home. if jen spent a total of 1 hour bicycling, find the two rates.

How do you summarize data in a two-way frequency table?

The magnitude, m, of an earthquake is defined to be m=log l/s, where i is the intensity of the earthquake (measured by the amplitude of the seismograph wave) and s is the intensity of a “standard” earthquake, which is barely detectable. what is the magnitude of an earthquake that is 1,000 times more intense than a standard earthquake? use a calculator. round your answer to the nearest tenth.

For each polynomial, determine the degree and write the polynomial in descending order. a. –4x^2 – 12 + 11x^4 b. 2x^5 + 14 – 3x^4 + 7x + 3x^3
