4. Find the circumference of the circle. Use 3.14 for the value of x. Round your answer to the nearest tenth. 20 in

Which of the following is the equation that says that the product of a number and ten is equal to 20 percent of that number ? a) 10n= 2.0n b) 10+n=.20n c) n+ .20n=10 d) 10n=0.20n

If a || b and b | y, then ? a) x || y. b) x | a. c) a | y. d) a || y.

Graph the line that represents a proportional relationship between d and t with the property that an increase of 33 units in t corresponds to an increase of 44 units in d. what is the unit rate of change of dd with respect to t? (that is, a change of 11 unit in t will correspond to a change of how many units in d? )
