Ametallurgist has one alloy containing 32% copper and another containing 65% copper. how many pounds of each alloy must he use to make 44 pounds of a third alloy containing 42% copper? (round off the answers to the nearest hundredth.)

Step-by-step explanation:

        First alloy contains 32% copper and the second alloy contains 65% alloy.

We wish to make 44 pounds of a third alloy containing 42% copper.

       Let the weight of first alloy used be in pounds and the weight of second alloy used be in pounds.

       Total weight =        

      Total weight of copper =

       Subtracting 32 times first equation from second equation,

∴ 30.67 pounds of first alloy and 13.33 pounds of second alloy were used.

you divide the cost ($15) by the quantity (6) to get your questions answer. the yo-yo costs $2.50. hope this : )!

step-by-step explanation:

answer: domain and range mean all possible values of x and y that could be substituted to the inequality. a solution means all possible values that make the inequality statement true. so while the range is still all real numbers, the solution is the shaded area, for which y will always be greater than the line of the function.
