Inventory for a company is taken hourly from 10 to 4:00. At the start of the day, the warehouse had 65 boxes. Between 10 and 11, 7 boxes were shipped. From 11 to noon, 5 were sent, and another 9 between noon and 1 p.m.

The relationship between the cans of food and boxes of food that Ingrid collected can be determined by the mathematical equations involving addition/subtraction and multiplication/division.

 For addition/subtraction:

   D = x – y

Where D is difference, x is the number of cans of food, and y is the boxes. Substituting the known values,

    D = 6 – 8 = -2

 For multiplication/division:

   R = x/y

Where R is the ratio. Substituting the known values,

   R = 6/8 = ¾ = 0.75

The relationship between the number of cans of food and boxes of food collected by Ingrid is a ratio of 1 can to 3 boxes after simplification. This means there is 1 can for every 3 boxes.

Ingrid collected 6 cans of food and 18 boxes of food for the food bank. To describe the relationship between cans of food and boxes of food, we can use a mathematical ratio.

The ratio of cans to boxes is calculated by dividing the number of cans by the number of boxes. This gives us:

6 cans : 18 boxes

To simplify this ratio, we divide both numbers by their greatest common divisor, which is 6:

6 ÷ 6 = 1

18 ÷ 6 = 3

Therefore, the simplified ratio is:

1 can : 3 boxes

This means there is 1 can of food for every 3 boxes of food. This ratio helps us understand the proportional relationship between the two quantities.

The ratio of the perimeters of two squares with a side ratio of 3:1 is 3:1.

The ratio of the sides of two squares is 3:1. To find the ratio of their perimeters, we need to compare the lengths of their sides. Let's assume the length of the larger square is 3x and the length of the smaller square is x. The perimeter of the larger square is 4 times the length of its side, so it is 4 × 3x = 12x. The perimeter of the smaller square is 4 times the length of its side, so it is 4 × x = 4x. Therefore, the ratio of their perimeters is 12x:4x. Simplifying this ratio gives us 3:1.

The correct inequality to solve for the number of boxes of crayons Mr. Valentino can purchase with his budget is $1.75x ≥ $25.

The correct inequality to solve for the number of boxes of crayons Mr. Valentino can purchase with his budget of $25 is b. $1.75x ≥ $25.

This inequality states that the product of the cost per box, $1.75, and the number of boxes, x, must be greater than or equal to $25 to remain within his budget.

You can solve this inequality by dividing both sides by $1.75 to find the minimum number of boxes he can buy and still stay within his budget.

Answer:

[tex]\frac{m - 4}{m + 4} / (m + 2)[/tex] is equivalent to   [tex]\frac{(m - 4)}{(m + 4)(m + 2)}[/tex]

Step-by-step explanation:

Given Parameters;

(m-4)/(m+4) and (m+2)

Required:

To divide and write out the equivalent expression.

Two or more expressions are said to equivalent if and only if they give the same result.

Solving (m-4)/(m+4) divided by (m+2)

We have

[tex]\frac{m - 4}{m + 4}[/tex] divided by [tex]m + 2[/tex]

[tex]= \frac{m - 4}{m + 4} / (m + 2)[/tex]

Convert division to multiplication

[tex]= \frac{m - 4}{m + 4} *\frac{1}{(m + 2)}[/tex]

= [tex]\frac{(m - 4) * 1}{(m + 4) * (m + 2)}[/tex]

[tex]= \frac{(m - 4)}{(m + 4)(m + 2)}[/tex]

We can't simplify any further;

Hence, [tex]\frac{m - 4}{m + 4} / (m + 2)[/tex] is equivalent to   [tex]\frac{(m - 4)}{(m + 4)(m + 2)}[/tex]

To check if this is true

Let m = 1

[tex]\frac{m - 4}{m + 4} / (m + 2)[/tex] becomes

[tex]\frac{1 - 4}{1 + 4} / (1 + 2)[/tex]

[tex]\frac{-3}{5} / (3)[/tex]

[tex]\frac{-3}{5} * \frac{1}{3}[/tex]

[tex]\frac{-1}{5}[/tex]

And

[tex]\frac{(m - 4)}{(m + 4)(m + 2)}[/tex] becomes

[tex]\frac{(1 - 4)}{(1 + 4)(1 + 2)}[/tex]

[tex]\frac{(-3)}{(5)(3)}[/tex]

[tex]\frac{-1}{5}[/tex]

Hence, [tex]\frac{m - 4}{m + 4} / (m + 2)[/tex] is equivalent to   [tex]\frac{(m - 4)}{(m + 4)(m + 2)}[/tex]

To find the total cost of an item with sales tax, convert the tax rate to a decimal, multiply by the item's price, add the result to the original price, and round to the nearest cent. A $17.50 item with a 7% sales tax would cost a total of $18.73 after tax.

To calculate the total cost of an item with sales tax, you first need to determine the amount of sales tax by converting the percentage to a decimal and then multiplying by the item's cost. For an item priced at $17.50 with a 7% sales tax, you would convert 7% to a decimal (0.07) and then multiply this by $17.50. Therefore, the calculation would be:

Sales Tax = $17.50 x 0.07 = $1.225

Once you have the sales tax amount, you add it to the original price to find the total cost:

Total Cost = Original Price + Sales Tax

$17.50 + $1.225 = $18.725. After rounding to the nearest cent, the total cost would be $18.73.

hi therrre you are an awesome person

The value of d that makes the lines 2dx - y = -4 and 4x - y = -6 perpendicular is -1/8, as this value makes the product of their slopes equal to -1.

To determine which value(s) of d would make the two lines perpendicular, we have to evaluate the slopes of the two lines and set their product to be -1, since perpendicular lines have slopes that are negative reciprocals of each other. Rearranging the first equation, 2dx - y = -4, we get y = 2dx + 4, which has a slope of 2d. For the second equation, 4x - y = -6, rearranging gives y = 4x + 6, with a slope of 4.

The product of the slopes of two perpendicular lines should be -1, so:

(2d) * 4 = -1

Solving for d: d = -1/8.

Thus, when the value of d is -1/8, the two lines are perpendicular.

We want to find the equation of a cosine function after we apply some given transformations to it.

The equation of the resulting cosine curve is:

g(x) = -(1/4)*cos(x + 5) - 9/4.

Let's see how we got that equation:

First, we need to define all the transformations that we will be using:

Vertical shift:

For a given function f(x) a vertical shift of N units is written as:

g(x) = f(x) + N.

Horizontal shift:

For a given function f(x) a horizontal shift is written as:

g(x) = f(x + N).

Vertical compression.

For a function f(x) a vertical compression by a factor k is written as:

g(x) = (1/k)*f(x).

Vertical flip (or vertical reflection).

For a general function f(x) a vertical reflection is written as:

g(x) = -f(x).

So we start with:

f(x) = cos(x).

First we shift it to the left 5 units, so we get:

g(x) = f(x + 5)

Then we shift it up 9 units, then we get:

g(x) = f(x + 5) + 9

Then we compress it vertically by a factor of 4:

g(x) = (1/4)*(f(x + 5) + 9)

Then we flip it vertically:

g(x) = -(1/4)*(f(x + 5) + 9)

Replacing f by the cosine function we get:

g(x) = -(1/4)*( cos(x + 5) + 9)

g(x) = -(1/4)*cos(x + 5) - 9/4.

This is the equation of the resulting cosine curve.

After standardizing the given value using a Z-score, it is found that the probability of a person producing more than 76.7% of the cholesterol in their body is essentially zero.

The question is asking for the probability that a person produces more than 76.7% of the cholesterol in their body, given this production is normally distributed with a mean of 75% and a standard deviation of 0.5%. To calculate this, we can utilize Z-score which standardizes the deviation of a value from the mean, considering the standard deviation.

The Z-score for the value 76.7% is calculated as follows: (76.7 - 75) / 0.5 = 3.4.

Using the standard normal distribution, the probability of a Z-score being above 3.4 is extremely low, it's practically zero. Therefore, the probability that a person produces more than 76.7% of the cholesterol in their body is essentially zero.

To predict the behavior of the autonomous differential equation as t -> infinity, analyze the phase portrait of the system. The behavior of X(t) as t approaches infinity depends on the initial conditions. Verify the explicit solution of the DE when k=1 and a=B. Graph the solutions and observe their behavior as t-> infinity.

To predict the behavior of the autonomous differential equation dX/dt = k(a-X)(B-X) as t -> infinity, we can analyze the phase portrait of the system. The phase portrait will show the equilibrium points and the direction of the solutions as time increases. In this case, there will be two equilibrium points, one at X = a and one at X = B, assuming a < B. The behavior of X(t) as t approaches infinity depends on the initial conditions. If X(0) < a, the solution will approach X = a, and if X(0) > a, the solution will approach X = B.

To verify the explicit solution of the differential equation when k=1 and a=B, we substitute these values into the equation: X(t) = a - 1/(t+c). For the solution that satisfies X(0) = a/2, we substitute t=0 and X(0) = a/2 into the equation and solve for c. Similarly, for the solution that satisfies X(0) = 2a, we substitute t=0 and X(0) = 2a into the equation and solve for c. We can then graph these two solutions and observe that as t approaches infinity, X(t) approaches a for both solutions, which confirms our analysis from part (b).
