An electronics store makes a profit of $30 for every portable dvd player sold and $60 for every dvd recorder sold. the manager’s target is to make at least $250 a day on sales of the portable dvd players and dvd recorders. write an inequality that represents the number of both kinds of dvd players that can be sold to reach or beat the sales target. let p represent the number of portable dvd players and r represent the number of dvd recorders. a. 60p + 30r ≥ 250 b. 30p + 60r ≤ 250 c. 30p + 60r ≥ 250 d. 30p + 60r > 250

the answer is c.30p+60r>250 just read the question or poses of elimination on the questions.

false

step-by-step explanation:

false.   two legs of the trapezoid would be congruent, but the other two would not.   were all the legs congruent, then we'd have a square; were the 2 shorter sides congruent and the 2 longer sides also congruent, we'd have a rectangle.

take the logarithm of both sides (the base of the log doesn't matter):

apply the exponent property - this says that :

distribute the log terms on both sides:

group like terms together:

divide through both sides by the coefficient on :

you can do some additional rewriting here using the properties of the logarithm to simplify things if you like:
