The x- and y-coordinates of P, Q, and R are to be integers that satisfy the inequalities-4 ≤ x≤ 5and 6≤y≤16. How many different triangles with these properties could be constructed?

If Greg assembled at least 30 units on each of two days and was paid a total of $180.00 for assembling units on the two days, what is the greatest possible number of units that he could have assembled on one of the two days ?

In a certain bathtub, both the cold-water and the hot-water fixtures leak. The cold-water leak alone would fill an empty bucket in c hours, and the hot-water leak alone would fill the same bucket in h hours, where c < h. If both fixtures began to leak at the same time into the empty bucket at their respective constant rates and consequently it took t hours to fill the bucket, which of the following must be true?I 0<t<hII c<t<hIII c/2<t<h/2
