Soybean mean is 14% protein; cornmeal is 7% protein. How many pounds of each should be mixed together in order to get 280-lb mix
Marianna [84]

I have to form a couple of equations in order to solve it.

let the amount of soybean in the mixture be x and that of cornmeal be y

Step-by-step explanation:

x+y = 280

y = 280 - x

x*(14/100) + y*(7/100) = 280*(12/100)

Multiplying the whole equation by 100;

14x + 7y = 3360

in this equation,put y = 280 - x

14x +7 (280-x) = 3360

14x +1960 - 7x = 3360

14x - 7x = 3360 - 1960

7x = 1400

x = 200lbs

y = 280 - x

= 280 - 200

= 80 lbs

Inorder to make a 280lbs mixture having 12% protein, we should mix 200lbs of soyabean and 80 lbs of cornmeal

PLEASE HELP ASAP<br><br> Why was the Mexican-american war just or unjust. Explain with facts.
N76 [4]
As a result of the war, the Tejanos, Nuevo Mexicanos, and Californianos lost their homeland. Since neither nation would accept these individuals as full citizens, they were forced to assimilate into either culture by essentially erasing their own traditions. In this way they became second-class citizens. Therefore, the Mexican-American War was certainly unjust. Both nations, especially Mexico, endured hardships following the two year w

Pls help<br> Enter the equation for the graph.
prisoha [69]

Answer:

y=[1]cos([\frac{2\pi }{3}]x)

Step-by-step explanation:

Looking at the graph, we can see the domain to be from (0 , 2π).

Now we have to find one period that corresponds to cos(x).

The half-period of cos(x) for this graph appears to be pi/3 and adding another pi/3 gets us 2pi/3 to be our cosine period.

b = 2pi/3

a is the same range as cos(x). Range: (0,0)

y = [a] * cos ([b]*x)

y = [1] * cos([2pi/3]x)
