Answer:

0.125 and 1/8

Step-by-step explanation:

To convert a percentage to a decimal, divide by 100 to move 2 decimal places to the left.

12.50% / 100 = 0.125

To convert a percentage into a fraction, rewrite the decimal number you got and put it over 1. Multiply the numerator and denominator by 1000 to move 3 decimal places to the right and get your fraction.

[tex]\frac{0.125}{1}[/tex] · [tex]\frac{1000}{1000}[/tex] = 125/1000

Divide the numerator and denominator by the GCF, 125, to get your simplified fraction.

125/125 = 1

1000/125 = 8

125/1000 = 1/8

Answer:

To prove that two lines are parallel, we find their slope and verify that those slopes are equal. Perpendicular lines are lines that create 90 degree angles where they intersect. We can prove that two lines are perpendicular by finding their slopes and verifying that the slopes are negative reciprocals of one another.

The product of slope of both line is -1.

A line's slope is determined by how its y coordinate changes in relation to how its x coordinate changes. y and x are the net changes in the y and x coordinates, respectively. Therefore, it is possible to write the change in y coordinate with respect to the change in x coordinate as,

m = Δy/Δx where, m is the slope

As, We determine the slopes of two lines and confirm that they are equal in order to demonstrate that the lines are parallel.

Lines that connect at 90 degree angles are said to be perpendicular.

By determining the slopes of two lines and confirming that the slopes are negative reciprocals of one another, we can demonstrate that the lines are perpendicular.

Hence, the product of slope of both line is -1.

Answer:

y=3x-7

Step-by-step explanation:

we use the equation of the line:

y=mx+b

if the line is parallel, then the slope(m) of the line stays the same:

y=3x+b

we then substitute the ordered pair into the equation and solve for b:

-13 = 3(-2)+b

-13 = -6+b

-13+6 = b

-7 = b

now we substitute the b value into the original equation and the answer:

Step-by-step explanation:

The rate change of the distance between the car and the person at that instant will be 15.69 meter.

What is Pythagoras theorem?

The Pythagoras theorem states that in a right triangle, the square of the hypotenuse is equal to the sum of the square of the other two sides.

Given that;

A person stands 30 meters east of an intersection and watches a car driving away from the intersection to the north at 17 meters per second.

At a certain instant, the car is 161616 meters from the intersection.

Now,

Let the distance of the car from the intersection and from the person be x and y at any time t respectively.

So, We can apply the Pythagoras theorem as;

y² = x² + 10²

y = √ x² + 10²

Differentiate with respect to t , we get;

[tex]\frac{dy}{dt} = \frac{1}{2\sqrt{x^2 + 100} } 2x \frac{dx}{dt}[/tex]

[tex]\frac{dy}{dt} = \frac{1}{\sqrt{x^2 + 100} } x \frac{dx}{dt}[/tex]

Since, the person standing towards the intersection at 17 m/s.

dx/dt = 17

Hence, [tex]\frac{dy}{dt} = \frac{1}{\sqrt{x^2 + 100} } x *17[/tex]

At x = 16 meters

So, [tex]\frac{dy}{dt} = \frac{1}{\sqrt{24^2 + 100} } 24 *17[/tex]

[tex]\frac{dy}{dt} = 408 / \sqrt{676}[/tex]

[tex]\frac{dy}{dt} = 408 / 26[/tex]

[tex]\frac{dy}{dt} = 15.69[/tex]

Thus, The rate change of the distance between the car and the person at that instant will be 15.69 meter.

Answer:

There are 126 boys on the honor roll and 247 girls on the honor roll.

Step-by-step explanation:

Out of the 1,480 students in Gila Monster High School, a total of 373 of the students made the honor roll.

Let the number of girls that made the honor roll be g.

Let the number of boys that made the honor roll be b.

This means that:

b + g = 373_________________(1)

The number of girls who appeared on the honor roll was 5 less than twice the number of boys.

This means that:

g = 2b - 5___________________(2)

Let us insert (2) in (1):

b + (2b - 5) = 373

=> b + 2b - 5 = 373

3b = 373 + 5

3b = 378

=> b = 378 / 3 = 126

From (1):

b + g = 373

=> 126 + g = 373

g = 373 - 126

g = 247 girls

Therefore, there are 126 boys on the honor roll and 247 girls on the honor roll.

Step-by-step explanation:

Omar should use the system of equations y₁ = logx/log6, and y₂ = log(x+4)/log2 option second is correct.

It is another way to represent the power of numbers, and we say that 'b' is the logarithm of 'c' with base 'a' if and only if 'a' to the power 'b' equals 'c'.

The fraction 3/2 and square root of 2 are not equivalent because their decimal approximations (1.5 and about 1.41 respectively) are not the same.

To determine if a fraction like 3/2 is equal to the square root of 2, we would need to compare their decimal values.

First, divide 3 by 2 to get the decimal value for the fraction, which is 1.5.

For the square root of 2, we can use a calculator and find that its approximate decimal value is 1.41.

Therefore, since 1.5 is not equal to 1.41, the fraction 3/2 is not equivalent to the square root of 2.

The fraction 3/2 is not equal to the square root of 2. By comparing the values directly or using fractional exponents, we can see that squaring 3/2 gives us 9/4, which is not equal to 2, and numerically the square root of 2 is approximately 1.414.

To determine if the fraction 3/2 is equal to the square root of 2, we can compare them directly or convert them into the same format. Recall that fractional exponents serve as another way to represent roots. Specifically, an exponent of 1/2 equates to taking the square root of a number. Thus, [tex](3/2)^{2}[/tex] would equal 3/2 multiplied by itself, which is 9/4, and that is not equal to 2. Therefore, 3/2 is not the square root of 2. We can also numerically evaluate the square root of 2, which is approximately 1.414, and see that it does not equal 3/2, which is 1.5.

Another consideration is that the square root of any number x can be expressed as [tex]x^{1/2}[/tex]. For instance, [tex](\sqrt{2})^2[/tex] = 2 because [tex](2^{1/2})^2[/tex] equals [tex]2^{1/2 * 2}[/tex] = 2. When we do this with 3/2, we would have [tex](3/2)^{1/2} * (3/2)^{1/2}[/tex] = 3/2, which does not satisfy the equation for the square root of 2. Therefore, 3/2 is not equal to the square root of 2.

Let x represent number of redwood trees and y represent number of spruce trees.

We have been given that a park ranger bought 12 trees. We can represent this information in an equation as:

[tex]x+y=12...(1)[/tex]

[tex]y=12-x...(1)[/tex]

We are also told that redwood trees cost $24 each, so cost of x redwood trees would be [tex]24x[/tex].

Each spruce tree costs $16, so cost of y spruce trees would be [tex]16y[/tex].

Since the park ranger spent $208 on trees, so we can represent this information in an equation as:

[tex]24x+16y=208...(2)[/tex]

Upon substituting equation (1) in equation (2), we will get:

[tex]24x+16(12-x)=208[/tex]

[tex]24x+192-16x=208[/tex]

[tex]8x+192=208[/tex]

[tex]8x+192-192=208-192[/tex]

[tex]8x=16[/tex]

[tex]\frac{8x}{8}=\frac{16}{8}[/tex]

Answer:

The maximum profit of $  10277.32____ can be made when the selling price of the dog food is set to $ _34___ per bag.

Step-by-step explanation:

Profit = Revenue - Cost

P(x) = R(x) -C(x)

       = -31.72x^2 + 2,030x -( -126.96x + 26,391)

Distribute the minus sign

       = -31.72x^2 + 2,030x+126.96x - 26,391

 Combine like terms

      =   -31.72 x^2 + 2156.96 x - 26391

This is a parabola.  It is facing downwards.  The maximum profits is at the vertex ( where the max is)

vertex = h = -b/2a = -(2156.96)/(2*-31.72) = -2156.96/-63.44=34

Evaluate P(x) at x=34 to determine the profit

P(34) =  -31.72 (34)^2 + 2156.96 (34) - 26391

          -36668.32+73336.64-26391

          10277.32

The maximum profit of $10,243.32 can be made when the selling price of the dog food is set to $947.17. per bag.

1. Define the profit function: Profit [tex](\( P(x) \))[/tex] is calculated by subtracting the cost function [tex](\( C(x) \))[/tex] from the revenue function [tex](\( R(x) \)):[/tex]

[tex]\[ P(x) = R(x) - C(x) \][/tex]

2. Substitute the given revenue and cost functions:

[tex]\[ R(x) = -31.72x^2 + 2,030x \][/tex]

[tex]\[ C(x) = -126.96x + 26,391 \][/tex]

3. Plug in the revenue and cost functions into the profit function:

[tex]\[ P(x) = (-31.72x^2 + 2,030x) - (-126.96x + 26,391) \][/tex]

[tex]\[ P(x) = -31.72x^2 + 2,156.96x - 26,391 \][/tex]

4. Find the x-coordinate of the vertex of the profit function:

  The x-coordinate of the vertex is given by:

[tex]\[ x = \frac{-b}{2a} \][/tex]

  where [tex]\( a = -31.72 \) and \( b = 2,156.96 \).[/tex]

[tex]\[ x = \frac{-2,156.96}{2*(-31.72)} \][/tex]

  x ≈ 34

5. Calculate the maximum profit:

  Substitute x ≈ 34  into the profit function:

P(34) ≈ [tex]-31.72(34)^2 + 2,156.96(34) - 26,391[/tex]

P(34) ≈ 10,243.32

6. Determine the selling price per bag that maximizes profit:

  Plug x ≈ 34 into the revenue function to find the corresponding revenue:

[tex]\[ R(34)[/tex] ≈ [tex]-31.72(34)^2 + 2,030(34)[/tex]

[tex]\[ R(34)[/tex] ≈ [tex]32,183.68[/tex]

  Divide the revenue by the quantity x ≈ 34  to find the selling price per bag:

[tex]\[ \text{Selling price per bag}[/tex] ≈ [tex]\frac{32,183.68}{34}[/tex] ≈ [tex]947.17[/tex]

So, the maximum profit is approximately $10,243.32, and the selling price per bag that maximizes profit is approximately $947.17.
