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
It is 4 feet
Because it just is
Answer:
Should be 1 if im not wrong Then Mark Me brainliest
Step-by-step explanation:
a negative times a neg equals a posative
Neg x pos = neg
pos x neg = neg
pos x pos = pos
neg x neg = pos
so if there greater then over neg<, >,=
You would look at the problem for given f(x)=
x → -1 and neg times neg more or less
-1 x -1 = 1
Answer:
(a)
(b)$5955.71
(c)15.02 years
Step-by-step explanation:
For an initial principal P deposited in an account at an annual interest r compounded for a number of period k, the amount in the account after n years is given by the model:
(a)Aunt Ga Ga gave you $5,500 to save for college.
P=$5,500
Annual Interest, r=4%=0.04
Since interest is compounded quarterly, Number of Periods, k=4
Therefore, an exponential function modeling this situation is:
(b)After 2 years, i.e. when n=2
(c)When A(n)=$10000, we have:
