Lucky Purchased a prepaid phone card for 20$. long distance calls cost 21 cents a minute using this card. Lucy used her card only to make one long distance call. if the remaining credit on her card is $12.02 how many minutes did her call last?

Two angles are complementary. the large angle is 36 more than the smaller angle. what is the measure of the large angle?

Joe has some money in his bank account he deposits 45$ write an expression that represents the amount of money in joe's account

I've been working on this for a few days and i just don't understand, it's due in a few hours. you. the direction of a vector is defined as the angle of the vector in relation to a horizontal line. as a standard, this angle is measured counterclockwise from the positive x-axis. the direction or angle of v in the diagram is α.part a: how can you use trigonometric ratios to calculate the direction α of a general vector v = < x, y> similar to the diagram? part bsuppose that vector v lies in quadrant ii, quadrant iii, or quadrant iv. how can you use trigonometric ratios to calculate the direction (i. e., angle) of the vector in each of these quadrants with respect to the positive x-axis? the angle between the vector and the positive x-axis will be greater than 90 degrees in each case. part cnow try a numerical problem. what is the direction of the vector w = < -1, 6 > ?
