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

ok hear me out
Step-by-step explanation:
she crochets at a rate of 1/15 per day but if she can manage to get 3/15 done within maybe a day or two, then she will get 1 blanket done in 5 to 10 days. then 3 blankets could take anywhere from 15 - 30 days which leaves 30 days to spare. this probs isn’t what ur looking for but i have a pointttt
First you find your slope which is rise/run, so, 1/3, and a line this way (/) is positive, so it's positive 1/3.
Then you see where it crosses the y axis: -1.
Plug that into y=mx+b giving you y=1/3x-1.
Your answer is D.
The formula for the volume of a cylinder is:
r is the length of the radius and h is the height. Plug in the given values:
To the nearest hundredth, the volume is 28.27 in³.
