The mass of the particles that a river can transport is proportional to the sixth power of the speed of the river. a certain river normally flows at a speed of 3 miles per hour. what must its speed be in order to transport particles that are 200 times as massive as usual? round your answer to the nearest hundredth. the speed of the river must be about blank miles per hour

Match each inequality to the number line that represents its solution

Pls the last one and it has to be like number 6

(01.03 mc) which of the following is a step in simplifying the expression x multiplied by y to the power of 2 over x to the power of negative 3 multiplied by y to the power of 3, the whole to the power of negative 4. select one: a. x to the power of negative 4 multiplied by y to the power of negative 2, the whole over x to the power of negative 7 multiplied by y to the power of negative 1. b. x to the power of negative 4 multiplied by y to the power of negative 8, the whole over x to the power of 12 multiplied by y to the power of negative 12. c. x to the power of negative 4 multiplied by y to the power of negative 8, the whole over x to the power of negative 3 multiplied by y to the power of 3. d. x to the power of negative 4 multiplied by y to the power of negative 2, the whole over x to the power of negative 3 multiplied by y to the power of 3.
