Each box needs to have a minimum space of 576 cubic inches to hold the toy.

What is a cuboid?

A cuboid is a three-dimensional solid shape that has six rectangular faces, where each face meets at right angles with adjacent faces.

To calculate the space required for each box to hold a toy that is 8 inches tall by 12 inches wide and 6 inches deep, we need to calculate the volume of the toy.

The volume of the toy can be calculated as:

Volume = height x width x depth

Volume = 8 inches x 12 inches x 6 inches

Volume = 576 cubic inches

Therefore, each box needs to have a minimum space of 576 cubic inches to hold the toy.

Answer:

y = \(-\frac{1}{3}x+5\)

Step-by-step explanation:

Let the equation of the given line is,

y = mx + b

where 'm' = slope of the line

b = y-intercept of the line

Since slope of a line passing through two points \((x_1, y_1)\) and \((x_2, y_2)\) is represented by,

m = \(\frac{y_2-y_1}{x_2-x_1}\)

If the points are (0, 5) and (-3, 6),

Slope of the line 'm' = \(\frac{6-5}{-3-0}\)

                                 = \(-\frac{1}{3}\)

y-intercept of the line 'b' = 5

Therefore, equation of the given line will be,

y = \(-\frac{1}{3}x+5\)

The height of the skyscraper is 226.32 meters (rounded to the nearest hundredth of a meter)

An illustrative diagram is shown in the attachment below:

In the diagram, /TB/ is the height of the skyscraper

/BL/ is the horizontal distance from the base of the skyscraper to where London is standing

Point E is her eye level

From the diagram, we observe that the height of skyscraper

/TB/ = /TM/ + /MB/ = x + 1.73m

Now, to determine the height of the skyscraper, we will first determine the value of x

Consider ΔTME

∠TEM = 30°

/TM/ is the opposite and

/ME/ is the adjacent

From the formula

\(tan \theta =\frac{opposite}{adjacent}\)

/TM/ = x

/ME/ 389 m

Then, we can write that

\(tan30^{o} = \frac{x}{389}\)

∴ x = 389×tan30°

x = 224.58925 m

Recall that the height of the skyscraper /TB/ =  x + 1.73m

∴ /TB/ =  224.58925m + 1.73m

/TB/ = 226.31925m

/TB/ ≅ 226.32m

Hence, the height of the skyscraper is 226.32 meters (rounded to the nearest hundredth of a meter)

Scale drawings are used to represent a large drawing using smaller measurements

The equivalent of 5" in the drawing is 30' i.e. 30 feet

The scale is given as:

\(\mathbf{\frac 12" = 3'}\)

A single quote means feet, while a double quote means inches

So, the scale can be rewritten as:

\(\mathbf{\frac 12\ inches= 3\ feet }\)

Multiply both sides by 10

\(\mathbf{\frac 12\ inches \times 10 = 3\ feet \times 10}\)

Simplify

\(\mathbf{5\ inches = 30\ feet }\)

Rewrite as:

Step-by-step explanation:

Let's say we need t $2 bills and v $5 bills.

We need 9 more $2 bills than $5 bills, so:

t = 9 + v

We also know that the amount of money in t $2 bills is 2 * t = 2t. The amount of money in v + 9 $5 bills is 5 * (v + 9) = 5v + 45. These amounts are equal:

5v + 45 = 2t

Plug v + 9 in for t in 5v = 2t + 18:

5v = 2t + 18

5v = 2 * (9 + v) + 18

5v = 18 + 2v + 18

3v = 36

v = 12

We have 12 $5 bills, so that total cost is 12 * 5 = $60.

The gradient of the function \(f(x, y) = 9x^2 + 4y^2\)at point P(2, -1) is (36, -8).

Given function,

\(f(x, y) = 9x^2 + 4y^2\)at point P(2, -1),

we need to compute the partial derivatives with respect to x and y.

Step 1: Find the partial derivative with respect to x.
∂f/∂x = 18x

Step 2: Find the partial derivative with respect to y.
∂f/∂y = 8y

Step 3: Evaluate the partial derivatives at point P(2, -1).
∂f/∂x|_(2, -1) = 18(2) = 36
∂f/∂y|_(2, -1) = 8(-1) = -8

Step 4: Write the gradient as a vector.
Gradient = (∂f/∂x, ∂f/∂y) = (36, -8)

So, the gradient of the function\(f(x, y) = 9x^2 + 4y^2\)at point P(2, -1) is (36, -8).

To find the domain, you measure or count the widest part of this oval horizontally. So that is 3 units to the right of 0 and 3 units to the left of 0. I counted it exactly on the axis because that is the widest part of the oval.

To find the range, you again count or measure the widest part of the oval vertically. So that is 4 units above 0 and 4 units below 0.

The metric unit from pounds to tons is 250 pounds = 0.125 tons

From the question, we have the following parameters that can be used in our computation:

250 pounds = how many tons

As a general rule, we have

1 pound = 0.0005 tons

Multiply both sides of the equation by 250

So, we have

250 * 1 pound = 0.0005 tons * 250

Evaluate the products

250 pounds = 0.125 tons

Hence, the conversion is 250 pounds = 0.125 tons

The solution to system (M) using Cramer's Rule is x = 1 - k and y = 2k - 2, which corresponds to option (d).

Cramer's Rule can be used to solve a system of linear equations by finding the determinants of coefficient matrices. For system (M), the coefficient matrix is:

| S 1 |

| 2 1 |

The determinant of this matrix, denoted as D, is calculated as D = (S * 1) - (2 * 1) = S - 2.

Next, we create two matrices by replacing the corresponding column of the coefficient matrix with the constants from the right-hand side of the equations. The determinant of the first matrix, denoted as Dx, is calculated by replacing the first column with [0, k-1]:

| 0 1 |

| k-1 1 |

Similarly, the determinant of the second matrix, denoted as Dy, is calculated by replacing the second column with [2, k-1]:

| S 0 |

| 2 k-1 |

Using Cramer's Rule, the solution for the variables x and y can be found as x = Dx / D and y = Dy / D.

Substituting the determinants, we have:

x = (0 - (k-1)(S)) / (S - 2) = 1 - k

y = ((S)(k-1) - 2(0)) / (S - 2) = 2k - 2

Therefore, the solution to system (M) using Cramer's Rule is x = 1 - k and y = 2k - 2, which matches option (d).

The height of the building is 71 meters.

We can solve this problem using the similar triangles. The height of the building can be determined by setting up the following proportion:

(the height of pole) / (length of pole's shadow) = (height of building) / (length of building's shadow)

Substituting the given values:

2.8 / 1.49 = (height of building) / 37.5

To find the height of the building, we can cross-multiply and solve for it:

(2.8 * 37.5) / 1.49 = height of building

Calculating the expression on the right side:

(2.8 * 37.5) / 1.49 ≈ 70.7013

The required inequality x + m ≤ 510, and the distance is 316 miles.

Inequity occurs when two phrases are joined by a sign such as "not equal to," "more than," or "less than." The inequality illustrates the larger than and less than the relationship between variables and numbers.

Given that Mr. Estrada's car can only drive 510 miles on a full tank of petrol. He drove the car 194 miles after filling up the tank with gasoline.

Let,

x miles = distance already traveled

m miles = distance miles can travel with remaining gas

510 = max. miles can travel on a full tank

As per the given question,

The inequality will be written as,

x + m ≤ 510

194 + m ≤ 510

m ≤ 510 - 194

Apply the subtraction operation, and we get

m ≤ 316

Therefore, the required inequality x + m ≤ 510, and the distance is 316 miles.
