Step-by-step explanation:

To find the perimeter of a triangular prism, you need to add up the lengths of all three sides of the triangular base and all three sides of the rectangular lateral faces.

The formula for the perimeter of a triangular prism is P = a + b + c + 3l, where a, b, and c are the lengths of the sides of the triangular base, and l is the length of each of the rectangular lateral faces.

The perimeter of the triangular prism is solved

A three-dimensional solid object called a prism has two identical ends. It consists of equal cross-sections, flat faces, and identical bases. Without bases, the prism's faces are parallelograms or rectangles.

The volume of a prism is the product of its base area and height

Volume of Prism = B x h

where B = base area of prism

h = height of prism

Given data ,

To find the perimeter of a triangular prism, you need to add the lengths of all the edges. The edges of a triangular prism include the three sides of the base triangle and three additional edges connecting the corresponding vertices of the two base triangles.

So, the formula for finding the perimeter of a triangular prism is:

Perimeter = (Sum of the lengths of the three sides of the base triangle) + (Sum of the lengths of the three edges connecting the corresponding vertices of the two base triangles)

The stated combination of coins is not possible as the number of quarters are highly more than the number of dimes and nickels.

Let the number of dimes be x. So, the number of an nickels will be 2x. The number of quarters will be (30 - 3x). As per the known information, the one nickel is 0.05 dollars, one dime is 0.1 dollars and one quarter is with 0.25 dollars.

Now forming the expression -

x×0.1 + 2x×0.05 + (30-3x)×0.25 = 3

Performing multiplication on Left Hand Side of the equation

0.1x + 0.1x + 7.5 - 0.75x = 3

Performing addition on Left Hand Side of the equation

0.2x - 0.75x = 3 - 7.5

On subtraction we will find the value on Left Hand Side will be negative. Thus, the stated combination is not possible.

The rule that describes the composition transformation that maps ABCD to A''B''C''D'' is;

''Translation of negative 6 units x, 1 units y composition reflection across the x-axis''.

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

The given coordinates of parallelogram ABCD are;

⇒ (3, 5), (6, 5), (4, 1), (1, 1)

The coordinates of the parallelogram A'B'C'D' are;

⇒ A'(3, -5), B'(6, -5), C'(4, -1), D(1, -1)

The coordinates of the parallelogram A''B''C''D'' are;

⇒ D(-5, 0), C''(-2, 0), A''(-3, -4), B''(0, -4)

The image of the point (x, y), following a reflection about the x-axis is the point (x, -y).

And, The difference in the coordinates of the parallelogram ABCD and A'B'C'D' is the change in the sign of the y-coordinates

Therefore, the transformation that gives the parallelogram A'B'C'D' from the parallelogram ABCD is a reflection about the x-axis

Thus, The difference between the coordinates of the vertices of the parallelogram A'B'C'D' and the parallelogram A''B''C''D'', is a change in the x-value by (-6), and a change in the y-value by (+1)

Therefore, the parallelogram A''B''C''D'' can be obtained from parallelogram A'B'C'D', by a translation of -6 units (left) in the x-direction and a translation of 1 unit, x in the y-direction.

Which gives;

The composition transformation that maps the pre-image ABCD to the final image A''B''C''D'', (given that in a composition transformation, the transformation to the right is done first) are; which is the option;

Now,

[tex]AB = \left[\begin{array}{ccc}2&3\\-1&1\end{array}\right] \left[\begin{array}{ccc}1&9\\-3&k\end{array}\right] = \left[\begin{array}{ccc}-7&18+3k\\2&-9-k\end{array}\right][/tex]

Thus, in order for AB = BA, we must have that

[tex]\left[\begin{array}{ccc}-7&18+3k\\2&-9-k\end{array}\right] = \left[\begin{array}{ccc}-7&-6\\-6-k&-9-k\end{array}\right][/tex]

Equate the values, and we get

18 + 3k = -6

3k = -6 - 18

3k = -24

k = -8

and 2 = -6 - k

k = -6 - 2

k = -8

Step-by-step explanation:

You would need 100 ounces of apples to get 100% of your daily vitamin C.

We know that 8 ounces of apples contains 8% of your daily vitamin C.

To find out how many ounces of apples are needed to get 100% of your daily vitamin C, we can use the following proportion:

(8 ounces / 8%) = (x ounces / 100%)

where x represents the number of ounces needed for 100% of the daily vitamin C.

To solve for x, we can cross-multiply and divide:

8 ounces * 100% = 8% * x ounces

8 ounces * 100 = 8 * x ounces

800 = 8x

x = 100

Therefore, you would need 100 ounces of apples to get 100% of your daily vitamin C.

The quarter mile grounding rule for rural electric utilities for direct-buried jacketed distribution cables says that they must have at least 4 grounds per mile.

A utility cooperative is a specific kind of cooperative that is responsible for providing its members with a public utility, such as power, water, or telecommunications. Profits are either distributed to members as "patronage" or "capital credits," which are dividends paid on a member's investment in the cooperative, or they are reinvested for infrastructure. 

Every consumer is a shareholder and a member of the company. This means that, in contrast to investor-owned utilities where the amount of individual authority is determined by the number of shares held, all members have the same level of personal authority. Many utility cooperatives operate their business in accordance with a set of ideals based on the Rochdale Principles, just like cooperatives active in other industries.

Absolute value of expression | 6 - 10 | can be simplified into 4.

The absolute value of a number is its distance from zero on the number line, regardless of its sign. It is represented by enclosing the number inside two vertical bars (| |) and is always a non-negative number.

In mathematical terms, the absolute value of x is defined as:

|x| =

a) x if x >= 0

b) -x if x < 0

So, for any number x, its absolute value is always positive or zero.

The expression |6 - 10| represents the absolute value of the difference between 6 and 10. To find the absolute value, we need to consider only the magnitude of the result and ignore its sign. In this case, the difference between 6 and 10 is -4, which is a negative number. Therefore, to find the absolute value, we need to take the absolute value of -4, which is 4. So, the simplified expression is:

|6 - 10| = 4

If 29 student tickets were sold, then all possible values for the number of adult tickets that the drama club must sell in order to meet the show's expenses are 54 and 55 .

the price for each student ticket is $4.50 and adult is $8 ;

The number of people auditorium can hold is = no more than 84 people ;

the number of children tickets sold is = 29 tickets ;

Let "x" be number of adult tickets sold.

The total revenue from ticket sales = $4.50×29 + $8×(x)

⇒ $130.5 + $8x.

The total revenue must be at least $560,

So , $130.5 + $8x ≥ $560.

Subtracting $130.5 from both sides, we get $8x ≥ $429.5   ;

Dividing both sides by 8, we get x ≥ 53.69    ;

Since the number of adult tickets sold must be an integer, the minimum number of adult tickets that must be sold is 54.

The maximum number of people allowed in the auditorium is 84, so the maximum number of adult tickets that can be sold is 84 - 29 = 55.
