Wilmer spends at least 13 hours reading for his assignments each week, plus 1 hour completing each reading response assignment. the inequality that represents the total number of hours, y, wilmer reads for his various assignments each week is y≥x+13, where x represents the number of reading response assignments he completes.
this week, wilmer can spend only 5 hours total reading for his various assignments.
which explanation correctly analyzes whether there is a solution for this scenario?
there is no solution. for the inequality to be true, the value of x has to be negative. this is impossible because wilmer can't have a negative number of reading response assignments.
the ordered pair (−8,5) is a solution to the inequality y≥x+13. this ordered pair shows that wilmer can complete 8 reading responses in the 5 hours.
the ordered pair (5,18) is a solution to the inequality y≥x+13. this ordered pair shows that wilmer can complete 18 reading responses in the 5 hours.
there is no solution. for the inequality to be true, the value of x has to be a fraction. this is impossible because wilmer can't have a fractional number of reading response assignments.

Cone w has a radius of 8 cm and a height of 5 cm. square pyramid x has the same base area and height as cone w. paul and manuel disagree on how the volumes of cone w and square pyramid x are related. examine their arguments. which statement explains whose argument is correct and why? paul manuel the volume of square pyramid x is equal to the volume of cone w. this can be proven by finding the base area and volume of cone w, along with the volume of square pyramid x. the base area of cone w is π(r2) = π(82) = 200.96 cm2. the volume of cone w is one third(area of base)(h) = one third third(200.96)(5) = 334.93 cm3. the volume of square pyramid x is one third(area of base)(h) = one third(200.96)(5) = 334.93 cm3. the volume of square pyramid x is three times the volume of cone w. this can be proven by finding the base area and volume of cone w, along with the volume of square pyramid x. the base area of cone w is π(r2) = π(82) = 200.96 cm2. the volume of cone w is one third(area of base)(h) = one third(200.96)(5) = 334.93 cm3. the volume of square pyramid x is (area of base)(h) = (200.96)(5) = 1,004.8 cm3. paul's argument is correct; manuel used the incorrect formula to find the volume of square pyramid x. paul's argument is correct; manuel used the incorrect base area to find the volume of square pyramid x. manuel's argument is correct; paul used the incorrect formula to find the volume of square pyramid x. manuel's argument is correct; paul used the incorrect base area to find the volume of square pyramid x.
