1) there are 80 grams of salt in a 32% solution. find the weight of the solution

2) how much water should be evaporated from a 300 grams of a 20% salt solution to get a 25% salt solution

3) salt was mixed with pure water in a 1: 3 proportion. what is the percentage of salt in the new solution

4) 24 grams of salt and 16 grams of pure water were added to 160 grams of a 35% solution. what is the percentage of salt in the new solution

The width of a rectangle is 20 units. can the perimeter p of the rectangle be 64 units when its length x is 11 units? no, because p = 2x + 2(20) no, because p ≠ 2x + 2(20) yes, because p ≠ 2x + 2(20) yes, because p = 2x + 2(20)

Pls brainliest will be awarded if answer is correct

Write the contrapositive of the conditional statement. determine whether the contrapositive is true or false. if it is false, find a counterexample. a converse statement is formed by exchanging the hypothesis and conclusion of the conditional. a) a non-converse statement is not formed by exchanging the hypothesis and conclusion of the conditional. true b) a statement not formed by exchanging the hypothesis and conclusion of the conditional is a converse statement. false; an inverse statement is not formed by exchanging the hypothesis and conclusion of the conditional. c) a non-converse statement is formed by exchanging the hypothesis and conclusion of the conditional. false; an inverse statement is formed by negating both the hypothesis and conclusion of the conditional. d) a statement not formed by exchanging the hypothesis and conclusion of the conditional is not a converse statement. true
