⟼ c = 22/7 × 4 m
⟼ c = 88/7 m
⟼ c = 12•57 m.

An animal feed to be mixed from soybean meal and oats must contain at least 168 lb of protein, 27 lb of fat, and 14 lb of mineral ash. each sack of soybeans costs $21 and contains 70 lb of protein, 9 lb of fat, and 7 lb of mineral ash. each sack of oats cost $7 and contains 21 lb of protein, 7lb of fat, and 1 lb of mineral ash. how many sacks of each should be used to satisfy the minimum requirements at minimum cos
Answers
Answer:
The animal farm should buy 1.775 bags of soybeans and 1.575 bags of oats
[tex]Cost = 51.275[/tex]
Step-by-step explanation:
The given parameters can be summarized as:
[tex]\begin{array}{cccc}{} & {x} & {y} & {Total} & {Protein} & {70} & {21} & {168} &{Fats}& {9} & {7} & {27} & {Minerals} & {7} & {1} & {14}& {Cost} & {21} & {7} & {} \ \end{array}[/tex]
Where: x = Soybeans and y = Oats.
So, the system of equations are:
[tex]70x + 21y = 168[/tex]
[tex]9x +7y = 27[/tex]
[tex]7x + y = 14[/tex]
[tex]Cost = 21x + 7y[/tex]
The best way to solve this, is using graph
Plot the following equations on a graph, and get the points of intersection:
[tex]70x + 21y = 168[/tex]
[tex]9x +7y = 27[/tex]
[tex]7x + y = 14[/tex]
From the attached graph, we have:
[tex](x_1,y_1) = (1.636,2.545)[/tex]
[tex](x_2,y_2) = (1.775,1.575)[/tex]
[tex](x_3,y_3) = (2.023,1.256)[/tex]
Substitute each of the values of x's and y's in the cost function to get the minimum cost:
[tex]Cost = 21x + 7y[/tex]
[tex](x_1,y_1) = (1.636,2.545)[/tex]
[tex]Cost = 21 * 1.636 + 7 * 2.545[/tex]
[tex]Cost = 52.171[/tex]
[tex](x_2,y_2) = (1.775,1.575)[/tex]
[tex]Cost = 21 * 1.775 + 7 * 1.575[/tex]
[tex]Cost = 48.3[/tex]
[tex](x_3,y_3) = (2.023,1.256)[/tex]
[tex]Cost = 21 * 2.023 + 7 * 1.256[/tex]
[tex]Cost = 51.275[/tex]
The values of x and y that gives the minimum cost is:
[tex](x_2,y_2) = (1.775,1.575)[/tex]
and the minimum cost is:
[tex]Cost = 48.3[/tex]
Hence, the animal farm should buy 1.775 bags of soybeans and 1.575 bags of oats

Answers
Answer:
m<JMK = 54
m<JKH = 63
m<HLK = 90
m<HJL = 27
m<LHK = 63
m<JLK = 27
Step-by-step explanation:
1. Solve for m<JMK
It is given that (<HMJ) and (<JMK) form line (HK), meaning that they are supplementary angles. Thus, their degree measures add up to (180), using this one can form the following equation,
(<HMJ) + (<JMK) = 180
126 + (<JMK) = 180
(<JMK) = 54
2. Solve for m<JKH
It is given that the figure is a rectangle, one of the properties of a rectangle is that diagonals are congruent, and the diagonals bisect each other. This means that segments (JM) and (MK) are congruent. Hence, the triangle (JMK) is an isoceles triangle. Therefore, one can use the base-angles theorem, which states that (<MJK) is congruent to (<JKH). Since the sum of angle measures in any triangle is (180), one can form the following equation,
(<JMK) + (<MJK) + (<JKH) = 180
54 + 2(<JKH) = 180
<JKH = 63
3. Solve for m<HLK
As per its definition, the corner angles in a rectangle are always (90) degrees, this property is applicable for the given rectangle. Thus, (<HLK) = 90 degrees.
4. Solve for m<HJL
To solve for this angle, one can use similar logic as they did to solve for (<JKH). Form the following equation and solve,
(<HMJ) + (<HJL) + (<JHK) = 180
126 + 2(<HJL) = 180
(<HJL) = 27
5. Solve for m<LHK
The vertical angles theorem states that when two lines intersect, the opposite angles are congruent. One can apply this theorem here and say (<JMK) = (<HML). Then, to solve for this angle, one can use the same logic that they used to solve for (<JKH) and (<HJL). Form the equation and solve,
(<HML) +(<LHK) + (<HLJ) = 180
54 + 2(<LHK) = 180
<LHK = 63
6.Solve for m<JLK
To solve for this angle, one can use the same logic that they used to solve for (<LHK). Form the equation and solve,
(<LMK) + (<JLK) + (HKL) = 180
126 + 2(<JLK) = 180
<JLK = 27

We have 6 total options.

Is figure B a scale copy of Figure A ?? Yes Or No
Answers
Answer:
No
Step-by-step explanation:
Figure A has an horizontal length of 2 units and a vertical length of 2 units.
Figure B has an horizontal length of 9 units and a vertical length of 7 units
Thus:
Horizontal length of Figure B / Horizontal length of figure A = 9/2
Horizontal length of Figure B / Horizontal Length of Figure A = 7/2
Thus,
9/2 ≠ 7/2
This implies that their corresponding lengths are not corresponding to each other. Therefore, Figure B is not a scale copy of Figure A.

x = 0,5 ft

V = 2 ft³
Step-by-step explanation: See annex
c) V = y*y*x
d-1) y = 3 - 2x
d-2) V = (3-2x)* ( 3-2x)* x ⇒ V = (3-2x)²*x
V(x) =( 9 + 4x² - 12x )*x ⇒ V(x) = 9x + 4x³ - 12x²
Taking derivatives
V¨(x) = 9 + 12x² - 24x
V¨(x) = 0 ⇒ 12x² -24x +9 = 0 ⇒ 4x² - 8x + 3 = 0
Solving for x (second degree equation)
x =[ -b ± √b²- 4ac ] / 2a
we get x₁ = 1,5 and x₂ = 0,5
We look at y = 3 - 2x and see that the value x₂ is the only valid root
then
x = 0,5 ft
y = 2 ft and
V = 0,5*2*2
V = 2 ft³

Answer:
A) t = 0.25c +25
B) c = 52
C) 3 weekday shifts
Step-by-step explanation:
A. The amount Ella earns is $0.25 per cupcake, so for c cupcakes, that is ...
0.25c
In addition, she is paid $25, so her total amount she is paid is ...
t = 0.25c +25
__
B. In order to earn $38, the number of cupcakes sold must be ...
38 = 0.25c +25
13 = 0.25c . . . . . . subtract 25
52 = c . . . . . . . . . multiply by 4
Ella sold 52 cupcakes to earn $38.
__
C. On one of the average weekdays, Ella could be expected to earn ...
t = 0.25(36) +25 = 34
Then for 3 weekday shifts, her earnings would be 3($34) = $102. (It would take Ella 3 weeks to earn $300.)
On one of the average weekend shifts, Ella could be expected to earn ...
t = 0.25(62) +25 = 40.50
Then for 2 weekend shifts, her earnings would be 2($40.50) = $81. (It would take Ella 4 weekends to earn $300.)
Ella would earn $300 more quickly by working weekday shifts.
