The area and volume based on the information will be area 144 √3 square meters and 240√3 cubic meters
How to calculate the areaTo calculate the area of the hexagonal prism, you need to calculate the area of each face and add them up. To calculate the area of one face of the hexagon, you can use the following formula:
Area of a regular hexagon = (3 * √3) / 2 * side^2
Plug in the side length of 4m:
Area of a face = (3 * √3) / 2 * 4^2 = (3 * √3) / 2 * 16 = 24 * √3
So the area of one face is 24 * √3 square meters. There are a total of 6 faces, 3 of which are hexagons, so the total area of the hexagonal prism is:
Total area = 6 * (24 * √3) = 144 * √3 square meters
To calculate the volume of the hexagonal prism, multiply the area of one face by the height:
Volume = (24 * √3) * 10 = 240 * √3 cubic meters
So the volume of the hexagonal prism is 240 * √3 cubic meters

Which of the following is equal to the rational expression when x ≠ -2 or 3?
The simplification of the given rational expression when x is not equal to 2 or negative 3 is determined as (x + 1)/(x + 3).
What is Simplification of expression?Expressions can be made simpler by expanding any brackets, multiplying or dividing any terms, using the laws of indices if necessary, grouping like terms together by adding or subtracting, and finally rewriting the expression. The BODMAS rule states that when an expression has brackets ((),, []), we must first solve or simplify the bracket before moving on to "order" (which refers to powers and roots, etc.), followed by division, multiplication, addition, and subtraction from left to right.
The simplification of the given expression when x is not equal to 2 or negative 3 is determined as follows;

Find the HCF :
2x^3+x^2-3x and x^3-x
Answer: To find the highest common factor (HCF) of two polynomials, we can use the Euclidean algorithm for polynomials. The Euclidean algorithm involves dividing the larger polynomial by the smaller polynomial and continuing the division process until the remainder is zero. The last non-zero remainder is the HCF of the two polynomials.
In this case, we have:
2x^3 + x^2 - 3x = (2x^3 - x^3) + x^2 - 3x
= x^3 + x^2 - 3x
Now, we divide x^3 + x^2 - 3x by x^3 - x
x^3 + x^2 - 3x = x^3 - x * (1 + x - 3)
= x^3 - x * (x^2 - 2x + 3)
We cannot simplify this expression further, so the HCF of 2x^3 + x^2 - 3x and x^3 - x is x^3 - x.

3. A bumblebee of mass 0.015 kg is traveling at 21.0 m/sec when it collides with a windshield. How much kinetic energy does the bee have as it hits the windshield? Show work thanks for the help
Answer:
Step-by-step explanation:
KE = (1/2) * m * v^2
where KE is the kinetic energy, m is the mass of the object, and v is the velocity of the object.
We are given the mass of the bumblebee as 0.015 kg and its velocity as 21.0 m/sec. We can plug these values into the formula to calculate its kinetic energy:
KE = (1/2) * m * v^2
= (1/2) * 0.015 kg * (21.0 m/sec)^2
= (1/2) * 0.015 kg * 441.0 m^2/sec^2
= 2.92625 J
Therefore, the bumblebee has 2.92625 Joules of kinetic energy as it hits the windshield.
Answer:
The kinetic energy of the bumblebee as it hits the windshield is given by the equation KE = 0.5 x 0.015 kg x (21.0 m/s) squared. This gives us a total of 945 J of kinetic energy.

The value of "n" is approximately 2.6666667.
What is exponent ?Exponent is a mathematical operation that represents repeated multiplication of the same number.
We can start by simplifying the left side of the equation:
(2^(2n))^4 * (2^n)^2 = 2^16 - 1
Using the exponent rules:
a^m * a^n = a^(m + n)
We can simplify the left side of the equation further:
2^(4n + 2n) = 2^16 - 1
Combining the exponents:
2^(6n) = 2^16 - 1
Now we can use the fact that if a^m = a^n, then m = n to solve for "n":
6n = 16
Dividing both sides by 6:
n = 16/6 = 8/3

Two types of memberships are available for a water park
an unlimited use membership for $70 per month, or
a monthly $10 fee plus $5. 00 per visit
enter an equation that can be used to find the number of visits (v) per month needed for the two membership types to cost the same amount
Answer:
10+5v=70
Step-by-step explanation:
this is because you need to consider the outright monthly cost of $10 first. then you don't know how many visits you'll need so you have to fill in v and multiply it by the cost per visit. and it must equal 70 so that it is equal to the other membership.
The equation 70 = 10 + 5v is used to determine the number of visits per month needed for two membership types to cost the same. Solving the equation would provide that 12 visits a month will make both memberships cost the same.
Explanation:The subject of this question is Mathematics, and it is related to the topic of linear equations. Given the problem, we know that there are two types of membership options:
An unlimited use membership for $70 per month. This can be represented as: Y = 70, A membership that costs a monthly $10 fee plus $5 per visit. This can be represented as: Y = 10 + 5v.Here, Y represents the total cost of the membership each month and v represents the number of visits to the water park per month. You can set these two equations equal to each other in order to find the number of visits (v) needed for the two membership types to cost the same amount:
70 = 10 + 5v
You solve the equation for v to get: v = (70 - 10) / 5 = 12
Therefore, it would take 12 visits per month for both memberships to cost the same.

Shalu cycles to her school at an average speed of 12 km/hr. It takes her 20 minutes to reach the school. If she wants to reach her schoo n 15 minutes, what should be her average speed?
Answer:
She should walk at a rate of 16 km/hr
Step-by-step explanation:
At a rate of 12 km/hr, she would have traveled 4 km in 20 minutes. This can be calculated by finding the ratio of 20 minutes to 1 hour which is 1/3. We then multiply this ratio by the rate to find the distance Shalu needs to walk to school.
We then need to find the necessary km/hr in order for Shalu to travel 4 km in 15 minutes. 15 minutes is a quarter of 1 hr. Therefore a rate of 4 km/15 minutes is equal to a rate of 16 km/hr. This means that the average speed Shalu would have to walk is 16 km/hr.

3. Roma makes scented candles, which she sells for $5 each or $11 for 3. Yesterday she took 200 candles with her to a craft fair and sold them all, taking a total of $788.
How many of her candles did Roma sell for $5 at the craft fair?
Let's call the number of candles Roma sold for $5 each "x".
What is the unitary method's formula?
What is the unitary method's formula? The unitary method's formula is to identify the value of a single unit, then multiply that value by the number of units to obtain the required value.
Since she sold 200 candles in total, we know that x + 3y = 200, where y is the number of sets of three candles she sold for $11.
We also know that the total revenue was $788, so we can set up another equation based on the total revenue:
5x + 11y = 788
Now that we have two equations, we can use substitution to solve for x. First, let's solve for y:
y = (200 - x) / 3
Plugging this expression for y into the second equation:
5x + 11((200 - x) / 3) = 788
Expanding and simplifying the equation:
5x + (2200 - 11x) / 3 = 788
Multiplying both sides by 3 to get rid of the fraction:
15x + 2200 - 11x = 2364
Combining like terms:
4x = 164
Finally, dividing both sides by 4 to solve for x:
x = 41
