(a picture will be provided as well)

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.

Answer:

No solution

Step-by-step explanation:

They must intersect  to have one solution. For infinite many solutions, the lines would be on top of each other.

Direct and Inverse proportionality was discussed with examples.

Direct proportionality: Direct proportionality means the change of a similar kind.

For example, as pressure increases, density also increases, which means both the parameters (pressure and density) are experiencing a similar kind of change i.e. increment in their magnitude.

The constant of proportionality is the ratio that relates two given values.

For example, Density ∝ pressure

Density = k(Pressure)

Here k  is the constant of proportionality

Inverse proportionality: Inverse proportionality means the change of the opposite kind.

For example, as the population increases, natural resources decrease, which means parameters(population and natural resources) are experiencing the opposite kind of change i.e one is increasing other is decreasing.

Thus, Direct and Inverse proportionality were discussed with examples.

x  =  0,5 ft

y =  2 ft   and

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:

6:3

Step-by-step explanation:

Answer and Step-by-step explanation:

3 of the options are not to be chosen, and 3 are wanted.

That means that anything above 3 (so, 4, 5, or 6) are the numbers that are wanted, while the numbers 1, 2, and 3 are not wanted.

We have 6 total options.

The ration would be:

3:6, or 3 to 6. This reduces down to 1:2, or 1 to 2.

That means that there is a 50% chance of getting 4, 5, or 6.

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

Answer:

this is correct on plato/edmentum

Step-by-step explanation:

For an equation to be viable, the result of the equation must be positive (i.e. greater than 1).

The 2 templates, the farmer created have two solutions, but only one of the solutions are viable.

For the first template, we have:

[tex]x \to[/tex] length of the shorter leg of the triangle

[tex]z \to[/tex] length of the longer leg of the triangle

From the question, we have:

[tex]z = 4 + 6x[/tex]

The area (y) of the first template is:

[tex]y = \frac{1}{2}xz[/tex] --- area of a triangle

So, we have:

[tex]y = \frac{1}{2}x(4 + 6x)[/tex]

Open bracket

[tex]y = 2x + 3x^2[/tex]

For the second template, we have:

[tex]Width = 5 + x[/tex]

[tex]Length = 3[/tex]

So, the area (y) of the second template is:

[tex]y = Length \times Width[/tex] --- area of a rectangle

This gives:

[tex]y = 3 \times (5 + x)[/tex]

[tex]y = 3(5 + x)[/tex]

[tex]y = 15 + 3x[/tex]

So, the expression for both areas are:

[tex]y = 2x + 3x^2[/tex] --- template 1

[tex]y = 15 + 3x[/tex] --- template 2

Both areas must be equal. This is represented as:

[tex]2x + 3x^2 = 15 + 3x[/tex]

Collect like terms

[tex]3x^2 +2x - 3x - 15 = 0[/tex]

[tex]3x^2 - x - 15 = 0[/tex]

Solve for x using quadratic formula, we have:

[tex]x = \frac{-b \± \sqrt{b^2 - 4ac}}{2a}[/tex]

Where:

[tex]a = 3; b =-1; c=-15[/tex]

So, we have:

[tex]x = \frac{-(-1) \± \sqrt{(-1)^2 - 4\times 3 \times -15}}{2 \times 3}[/tex]

[tex]x = \frac{1 \± \sqrt{181}}{6}[/tex]

[tex]x = \frac{1 \± 13.5}{6}[/tex]

Split

[tex]x = \frac{1 + 13.5}{6} \ or \ x = \frac{1 + 13.5}{6}[/tex]

[tex]x = \frac{-12.5}{6} \ or \ x = \frac{14.5}{6}[/tex]

[tex]x = -2.08 \ or \ x = 2.42[/tex]

We can see that x has 2 solutions, but only 1 of the solutions is viable because the other is negative.

Hence, option (a) is correct

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.

Step-by-step explanation:

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
