)tim and judy mix two kinds of feed for pedigreed dogs. they wish to make 25 pounds of feed worth $0.32 per pound by mixing one kind worth $0.14 per pound with another worth $0.39 per pound. how many pounds of the cheaper kind should they use in the mix? (round to the nearest pound.)

we use 18 pound use cheaper mix and  7 pound of expensive mix

Explanation:

we consider here

food 1  = x

and food 2 = y

so

total cost of food 1 is = 0.14 x

total cost of food 2 is = 0.39 y

total cost when mix (x+y)  is = 25 × 0.32 = 8

we know here x + y = 25

so y = 25 -x

so adding total cost

0.14 x + 0.39 y = 8

put here y value

0.14 x + 0.39 ( 25 - x) = 8

x = 7  pounds

and

y = 25 - 7

y = 18 pounds

so we use 18 pound use cheaper mix and  7 pound of expensive mix

    racial conflict and discrimination has existed ever since man learned to kill with rocks and bones. these conflicts arose from disputes between territory, power, wealth, religion, or simple difference. some of the most infamous racial disputes include slavery, the holocaust, and the civil rights movement.

    these listed disputes often resulted in casualties from all sides. riots, wars, imprisonment, and lynching are all commonly associated with racial conflict on severe levels.

      however, racism is an improving issue in recent decades. people are being more accepting and welcoming of diverse populations. though, the world isn't perfect and it will take much more time, if ever, until the world is rid of racism.
