The foam are used to package this product is cubic centimeters.

The Area of the rectangular prism is the product of the length, breadth, and height of the given prism.

Area of rectangular prism = 2(length x width + length x height + width x length)

Area of rectangular prism = 2( 36 x 30 + 30 x60 + 60 x 36)

= 10080 cubic centimeters

Let's find the base area:

The formula to find the base area is,

B = ½bh

Triangle area = 1/2 x 15 x 20 x 6

Triangle area = 900

10080 - 900 = 9180

The SAA (Side-Angle-Angle) criterion is not a triangle similarity theorem.

Triangle similarity theorems are used to determine if two triangles are similar. Similar triangles have corresponding angles that are equal and corresponding sides that are proportional.  There are three main triangle similarity theorems:  AA (Angle-Angle) Criterion.

SSS (Side-Side-Side) Criterion: If the lengths of the corresponding sides of two triangles are proportional, then the triangles are similar. SAS (Side-Angle-Side) Criterion.

Option (d) is correct.

The standard deviation of the number of new built houses that will comply with municipal regulations is approximately 1.65

To find the standard deviation of the number of new built houses that will comply with municipal regulations, we can use the binomial distribution formula:

Standard Deviation (σ) = √(n * p * (1 - p))

where n is the number of trials (17 houses) and p is the probability of success (compliance rate of 8/10 or 0.8).

Plugging in the values, we have:

σ = √(17 * 0.8 * (1 - 0.8))

= √(17 * 0.8 * 0.2)

= √(2.72)

Therefore, the standard deviation of the number of new built houses that will comply with municipal regulations is approximately 1.65 (option d).

Step-by-step explanation:

After reducing all the book prices by 50%, the new median price is determined to be $7.70 (B)

To find the new median price after reducing all the book prices by 50%, we first need to calculate the reduced prices. By reducing each given price by 50%, we get $6.375, $7.40, $9.995, $4.975, $8.00, and $8.975 respectively.

Next, we arrange these reduced prices in ascending order: $4.975, $6.375, $7.40, $8.00, $8.975, and $9.995. The median is the middle value in this ordered list. Since there are six prices, the middle two values are $7.40 and $8.00.

To find the median, we take the average of these two values, which gives us ($7.40 + $8.00) / 2 = $7.70.

Therefore, the new median price, after reducing all the book prices by 50%, is $7.70 (B). This means that the median price of the books, after the reduction, is $7.70.

Step-by-step explanation: slope is the difference between the y values over the difference of the x values

The slope of the line that passes through A(0,−5) and B(3,−4) will be 1/3.

A slope is a tangent or angle at a point and a slope is the intensity of inclination of any geometrical lines.

Slope = Tanx where x will be the angle from the positive x-axis at that point.

The slope could be positive or negative.

The slope associated with two points (x₁, y₁) and (x₂, y₂) is given by

Slope = (y₂ - y₁)/(x₂ - x₁)

Slope m = (-4 + 5)/(3 - 0)

m = 1/3

Hence "The slope of the line that passes through A(0,−5) and B(3,−4) will be 1/3".

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

Rounding to the nearest meter, the height of the building is approximately 71 meters.

Answer:

Step-by-step explanation:

The sum of exterior angles for any polygon is 360.

so first add up all the given exterior angle:

30+35 = 65.

next, find all the exterior angles that you can find:

Exterior angle = 180-interior angle

so:

180-90 = 90

180-135 = 45

180-120 = 60

180-90=90

These are all that we can find.

now add these to 65:

90+45+60+90+65 = 350

To find x, subtract 350 from 360, which is the sum of exterior angles.

360-350 = 10

According to information given,  `a = (-16)T + (0)N = (-16)(2i + j - 2k) + 0(0i + 0j + k)` at `t = -1`, which is the correct answer.

`r(t) = (2t + 4)i + (t)j + (t^2)k, t = -1`.

To find `a=a_TT+a_NN` at `t = -1`.

First, find `T = r'(t)` and `N = T'/|T'|`,

where `r'(t)` is the unit tangent vector of the curve r(t) and `T'` is the derivative of T with respect to `t`.

To find `T = r'(t)`, differentiate r(t) with respect to t.

We get: `r'(t) = 2i + j + 2tk`.

So, `T = r'(-1) = 2i + j - 2k`.

Differentiating `T` with respect to `t`, we get `T' = 0i + 0j + 2k`.

So, `|T'| = 2`.

Therefore, `N = T'/|T'| = 0i + 0j + k`.

We know that `a = a_TT + a_NN`.

We have found `T` and `N`.

We need to find `a_T` and `a_N`.

To do that, find `a = r''(t)` where `r''(t)` is the acceleration vector of the curve r(t)

Differentiating `r'(t)`, we get `r''(t) = 0i + 0j + 2k`.

So, `a_T = r''(-1) .

T = 0i + 0j + 2k . (2i + j - 2k) = -4`.

Therefore, `a_T = -4` and `a_N = a - a_T = (r''(-1) . N) = 0`.

Hence, `a = (-4)T`.

Now, substituting `T` and `N`, we get

`a = (-4)(2i + j - 2k)

= -8i - 4j + 8k`.

Therefore, `a = -8i - 4j + 8k`.

So, `a = (-8)T + (0)N`.

Therefore, `a = (-8)T + (0)N

= (-8)(2i + j - 2k) + 0(0i + 0j + k)`.

Simplifying, we get `a = -16i - 8j + 16k`.

Hence, `a = (-16)T + (0)N

= (-16)(2i + j - 2k) + 0(0i + 0j + k)` at `t = -1`.

For Quadrilateral ABCD and Quadrilateral PQRS, if AD = 3, DC = 2x + 4, PS = 2, and SR = 5, the value of x is = 3.

Here's how to solve the problem:

Given, AD = 3, DC = 2x + 4, PS = 2 and SR = 5. Now, we need to find x.

A quadrilateral is a four-sided figure. The given quadrilateral ABCD and quadrilateral PQRS are shown below:

From the above figure, we can see that:

AB + BC + CD + DA = PQ + QR + RS + SP (Opposite sides of a quadrilateral are equal)

So,

3 + BC + (2x + 4) + DA = 2 + 5 + QR + 2 (Substituting the given values)

Simplifying the above equation, we get:

BC + DA + 2x = QR - 4

Let us consider the below figure:

From the above figure, we can see that:

QR + RS = AD (Sum of two opposite sides of a parallelogram is equal to the sum of the other two opposite sides)

QR + 5 = 3 + DC

QR + 5 = 3 + (2x + 4)

QR = 2x + 2

Simplifying the above equation, we get:

QR = 2(x + 1)

Substituting the value of QR in the above equation, we get:

BC + DA + 2x = 2(x + 1) - 4

BC + DA + 2x = 2x - 2

Simplifying the above equation, we get:

BC + DA = - 2

But the length of a line segment is always a positive number.

So,BC + DA > 0

Putting the values of BC and DA as BC = x + 1 and DA = 2, we get:

x + 1 + 2 > 0x + 3 > 0x > - 3

So, the value of x is greater than - 3.

Hence, the correct answer is (3) 3.
