Achemist needs 180 ml of a 52% solution but has only 44% and 62% solution available. find how many milliliter of each that should mixed to get the desired solution

100 ml of 44% solution   and    80 ml of 62% solution

Step-by-step explanation:

44% solution + 62% solution = Mixture

      0.44x      + 111.6 - 0.62x   =   93.6

                         111.6 - 0.18x    =   93.6      added 0.44x and -0.62x

                                 - 0.18x    =  -18         subtracted 111.6

                                          x    =  100        divided by -0.18

44% solution + 62% solution = Mixture

        100       +         ____      =  180

                                 ____      =   80

proofs involving isosceles triangles often require special consideration because an isosceles triangle has several distinct properties that do not apply to normal triangles.(more about triangle types) therefore, when you are trying to prove that two triangles are congruent, and one or both triangles, are isosceles you have a few theorems that you can use to make your life easier.

step-by-step explanation:

an isosceles triangle has two congruent sides and two congruent angles. the congruent angles are called the base angles and the other angle is known as the vertex angle. ∠bac and ∠bca are the base angles of the triangle picture on the left. the vertex angle is ∠abc
