The surface area of the prism is 224 ft².
What is a prism?Having identical endpoints in three dimensions, a prism is a solid object. This combination consists of flat faces, identical bases, and equal cross-sections.
We are given a figure of a prism having a square base.
We know that
Surface Area of Prism (A) = 2a² + 4ah
We are given the following information:
a = 4 ft
h = 12 ft
On substituting these values in the formula, we get
⇒A = 2(4)² + 4(4)(12)
⇒A = 2(16) + (16)(12)
⇒A = 32 + 192
⇒A = 224 ft²
Hence, the surface area of the prism is 224 ft².

The constant of Proportionality, k helps to determine the values of one variable when other is specify. The value of x when y = 3 is equals to the 3/4 or 0.75.
Proportionality defined as ratio that exists between two quantities. Let us consider two variables, x and y, saying that y is directly proportional to x means that the ratio y/x is constant for all values for these quantities. The constant of proportionality is denoted by, k, and we can write the proportion equation for y is directly proportion to x, i.e., y = kx, --(1), where k is constant of proportionality
Also, y =24 when x= 6
To determine the value of k, substitute the known value, y = 24, x = 6
=> 24 = k×6
=> k = 24/6 = 4
so, equation (1) is y = 4x --(2)
To determine the value of x by substituting y = 3,
=> y = 4x
=> 3 = 4x
=> x = 3/4

First divide 97.65625 by 2.5. True? Or false
True, 39.0625 is the value of First division .
What is division, and how does it work?
Multiplication is the opposite of division. When you divide 12 into three equal groups, you get four in each group if three groups of four add up to 12, which they do when you multiply. The primary objective of division is to count the number of equal groups that are created or the number of individuals in each group after a fair distribution.
In mathematics, division is the process of dividing a number into equal parts and determining how many of those parts there are in total. For instance, breaking 15 into 3 equal groups of 5 is equivalent to dividing 15 by 3.
= 97.65625 / 2.5
= 39.0625

There are 1,000 grams in 1 kilogram. Lucas has a bucket with 2 kilograms of sand. Mac has a bucket with 4 kilograms of sand. How many grams of sand do they have in all?
In total, they have 6000 grams of sand.
What are basic arithmetic operations?
The basic arithmetic operations are the four fundamental mathematical operations used to manipulate numerical values. They are addition, subtraction, multiplication, and division.
To solve the problem, we need to know the conversion factor between kilograms and grams, which is 1 kilogram = 1000 grams.
First, we can find out how many grams of sand Lucas has in his bucket. We are given that he has 2 kilograms of sand, so we can use the conversion factor to convert kilograms to grams:
2 kilograms x 1000 grams/kilogram = 2000 grams
Therefore, Lucas has 2000 grams of sand in his bucket.
Next, we can find out how many grams of sand Mac has in his bucket. We are given that he has 4 kilograms of sand, so we can use the conversion factor again:
4 kilograms x 1000 grams/kilogram = 4000 grams
Therefore, Mac has 4000 grams of sand in his bucket.
To find out the total amount of sand they have in grams, we can add the amount of sand each of them has:
2000 grams + 4000 grams = 6000 grams
Therefore, in total, they have 6000 grams of sand.

Step-by-step explanation:
these 2 parallel lines create similar triangles.
that mags they're is one common scaling factor for the side lengths bergen the 2 triangles.
and that means they must have the same ratio.
the large triangle has the side lengths
24 + 9 = 33
32 + x
the smaller triangle has the corresponding side lengths
24
32
so, the equal ratios are
24/33 = 32/(32+x)
24(32 + x) = 32×33
32 + x = 32×33/24 = 4×11 = 44
x = 44 - 32 = 12
Suppose you place $1,500 in an account that will pay annual
interest of 5% compounded continuously. What will be your balance
in your account after 10 years?
The balance in your account after 10 years will be $2,473.08.
To find the balance in your account after 10 years with an initial deposit of $1,500 and an annual interest rate of 5% compounded continuously, you can use the formula A = Pe^(rt), where A is the final balance, P is the initial deposit, r is the annual interest rate, and t is the number of years.
In this case, P = $1,500, r = 5%, and t = 10. Plugging these values into the formula, we get:
A = $1,500 * e^(0.05 * 10)
A = $1,500 * e^(0.5)
A = $1,500 * 1.64872
A = $2,473.08
the balance in your account after 10 years will be $2,473.08.

Are rectangles always squares?Every square is also a rectangle because a square is a parallelogram with all particular corners at right angles. Yet not all rectangles are squares; for a rectangle to be a square, all of its sides must be the same length.
We can infer that the two rectangles may have a similar shape but differ in size because we can see how similar they are to one another.
By using the fact that the ratio of the adjacent angles of two comparable rectangles is the same, we can determine the length of the following rectangle.
Let x be the second rectangle's length. Then we can establish a ratio:

For a control to reference trajectory, a robot at (5, 0) should
join a line trajectory line from (2, 3) to (8, 7). Calculate the
normalized orthogonal distance.
The normalized orthogonal distance between the robot and the reference trajectory line is approximately 4.16.
The normalized orthogonal distance is the distance between the robot and the reference trajectory line. We can use the following formula to calculate the normalized orthogonal distance:
normalized orthogonal distance = |(y2 - y1)x0 - (x2 - x1)y0 + x2y1 - y2x1| / √((y2 - y1)^2 + (x2 - x1)^2)
Where (x0, y0) is the position of the robot, and (x1, y1) and (x2, y2) are the positions of the two points on the reference trajectory line.
Plugging in the values given in the question, we get:
normalized orthogonal distance = |(7 - 3)5 - (8 - 2)0 + 8*3 - 7*2| / √((7 - 3)^2 + (8 - 2)^2)
Simplifying the equation, we get:
normalized orthogonal distance = |20 - 0 + 24 - 14| / √(16 + 36)
normalized orthogonal distance = |30| / √(52)
normalized orthogonal distance = 30 / √(52)
normalized orthogonal distance ≈ 4.16

We are given that;
Radius=5units
Radian=180 degrees
Now,
The arc length of a circle is given by the formula:
arc length = (r * theta)
where r is the radius of the circle and theta is the angle in radians subtended by the arc at the center of the circle.
We know that the radius of the circle is 5 units, and we want to find the radian measure of an arc that subtends an angle of 180 degrees.
Since 180 degrees is half of a full circle, the arc length of this arc will be half of the circumference of the circle:
arc length = (1/2) * 2 * pi * r
= pi * r
Plugging in r = 5, we get:
arc length = pi * 5 = 5pi
Now we can use the formula for arc length to find the radian measure of the arc:
arc length = r * theta
5pi = 5 * theta
theta = pi
Therefore, by the arc length the answer will be [tex]\pi[/tex] radians.

What are the characteristics of a parallelogram?A quadrilateral with the opposing sides parallel is known as a parallelogram. It has numerous crucial traits, including:
A parallelogram has equal-length opposite sides. A parallelogram has opposite angles that are equally sized. A parallelogram's diagonals cut each other in half. A parallelogram is divided into four equal-sized triangles by its diagonals. A parallelogram's internal angles add up to 360 degrees. A parallelogram is classified as a rectangle if it also contains four right angles, making it a rectangle-shaped parallelogram.
Let us suppose the smaller angle = x.
The other angle is thus x + 36.
In a parallelogram the opposite angles are equal thus:
x + x + x + 36 + x + 36 = 360
4x + 72 = 360
