What is the minimum surface area of a box whose base is a square and with no top that holds 32 cm³. a 16 b 32 c 64 d 48
Answers
The minimum surface area of the box is 68 cm², which corresponds to option (d).
How to calculate the surface area of box?Let the side length of the square base be x and the height of the box be h. Then, we have:
Volume of the box = x²h = 32
h = 32/x²
The surface area of the box is given by:
S = x² + 4(xh) = x² + 4x(32/x²) = x² + 128/x
To find the minimum surface area, we can differentiate S with respect to x, set the derivative equal to zero, and solve for x:
dS/dx = 2x - 128/x² = 0
2x = 128/x²
x⁴ = 64
x = 2 cm
Note that we need to check that this critical point gives us a minimum surface area. We can do this by checking the second derivative:
d²S/dx² = 2 + 256/x³
d²S/dx² at x = 2 is positive,
indicating that this critical point gives us a minimum surface area.
Substituting x = 2 in the equation for S, we get:
S = 2² + 128/2 = 4 + 64 = 68
Therefore, the minimum surface area of the box is 68 cm², which corresponds to option (d).

What are reasonable domain and range values for this function, if the longest side length of the box can be no greater than 20 in. ? Write the answers in interval notation
Answers
The range of the function f(x) is Range: [0, 125] In interval notation, this can be written as [0, 125] if the longest side length of the box can be no greater than 20 in.
The function f(x) = 1.25x^2 models the packaging costs, in cents, for a rectangular prism-shaped box with side lengths of 2x in., 2x in., and 0.5x in.
We need to determine the reasonable domain and range values for this function, given that the longest side length of the box can be no greater than 20 in.
Since the longest side length is 20 in., we know that:
2x ≤ 20
x ≤ 10
Therefore, the domain of the function f(x) is all real numbers less than or equal to 10, or: Domain: [-∞, 10]
To find the range of the function, we need to examine the behavior of the function as x varies. Since the coefficient of x^2 is positive, the function is quadratic with a minimum value at x = 0. Therefore, we know that the range of the function must start at its minimum value, which is f(0) = 0, and increase as x increases.
To determine the upper limit of the range, we can evaluate f(x) when x = 10 (the maximum value of x allowed):
f(10) = 1.25(10)^2 = 125
Therefore, the range of the function f(x) is:
Range: [0, 125]
In interval notation, this can be written as [0, 125].

Calculate the change in entropy of the system when 10. 0 g of ice at −10. 0 °C is converted into water vapour at 115. 0 °C and at a constant pressure of 1 bar. The molar constant-pressure heat capacities are: Cp,m(H2O(s)) = 37. 6 J K−1 mol−1; Cp,m(H2O(l)) = 75. 3 J K−1 mol−1; and Cp,m(H2O(g)) = 33. 6 J K−1 mol−1. The standard enthalpy of vaporization of H2O(l) is 40. 7 kJ mol−1, and the standard enthalpy of fusion of H2O(l) is 6. 01 kJ mol−1, both at the relevant transition temperatures
Answers
Answer:
Step-by-step explanation:
To calculate the change in entropy, we need to consider each step of the process separately and then add up the individual entropy changes.
Step 1: Heating ice from -10.0°C to 0°C
The heat required for this step can be calculated using the formula:
q = m * Cp * ΔT
where m is the mass of ice, Cp is the molar constant-pressure heat capacity of ice, and ΔT is the change in temperature.
q = 10.0 g / 18.01528 g/mol * 37.6 J/K/mol * 10.0°C = 20.8 J
The entropy change for this step can be calculated using the formula:
ΔS = q / T
where T is the temperature in Kelvin.
ΔS = 20.8 J / 263.15 K = 0.079 J/K
Step 2: Melting ice at 0°C
The heat required for this step can be calculated using the formula:
q = n * ΔHfus
where n is the number of moles of ice and ΔHfus is the standard enthalpy of fusion of water.
n = 10.0 g / 18.01528 g/mol = 0.555 mol
q = 0.555 mol * 6.01 kJ/mol = 3.33 kJ = 3330 J
The entropy change for this step can be calculated using the formula:
ΔS = q / T
where T is the melting point of water in Kelvin (273.15 K).
ΔS = 3330 J / 273.15 K = 12.2 J/K
Step 3: Heating water from 0°C to 100°C
The heat required for this step can be calculated using the formula:
q = m * Cp * ΔT
where m is the mass of water (which is equal to the mass of ice that melted), Cp is the molar constant-pressure heat capacity of water, and ΔT is the change in temperature.
q = 10.0 g / 18.01528 g/mol * 75.3 J/K/mol * 100.0°C = 415.9 J
The entropy change for this step can be calculated using the formula:
ΔS = q / T
where T is the average temperature during the heating process (which is 50°C).
ΔS = 415.9 J / 323.15 K = 1.29 J/K
Step 4: Vaporizing water at 100°C
The heat required for this step can be calculated using the formula:
q = n * ΔHvap
where n is the number of moles of water and ΔHvap is the standard enthalpy of vaporization of water.
n = 10.0 g / 18.01528 g/mol = 0.555 mol
q = 0.555 mol * 40.7 kJ/mol = 22.6 kJ = 22600 J
The entropy change for this step can be calculated using the formula:
ΔS = q / T
where T is the boiling point of water in Kelvin (373.15 K).
ΔS = 22600 J / 373.15 K = 60.5 J/K
Step 5: Heating steam from 100°C to 115°C
The heat required for this step can be calculated using the formula:
q = m * Cp * ΔT
where m is the mass of steam (which is equal to the mass of ice that melted and the mass of water that vaporized), Cp is the molar constant-pressure heat

A. 327$/print
B. 552$/print
C. 752$/print
D. 227$/print
Answers
The rate of change of cost when the number of magazines printed per day is 17 is 752 dollars per print. The correct option is C.
The function C(x) = 25x² - 98x represents the cost of printing magazines per day at a printing press. To find the rate of change of cost when 17 magazines are printed per day, we need to calculate the derivative of the function with respect to x (the number of magazines printed), which represents the rate of change at a given point.
The derivative of C(x) with respect to x can be found using the power rule for differentiation. For a function of the form f(x) = [tex]ax^n[/tex], its derivative is f'(x) = [tex]n*ax^{(n-1)[/tex].
Applying the power rule to our function, we get:
C'(x) = 2(25x) - 98 = 50x - 98.
Now, we need to evaluate C'(x) when x = 17 (the number of magazines printed per day):
C'(17) = 50(17) - 98 = 850 - 98 = 752.
Therefore, the rate of change of cost when the number of magazines printed per day is 17 is 752 dollars per print. So, the correct answer is: C. 752$/print.

The slant height if the cone is 26 cm. what is the volume of a cone having a radius of 10 cm and a slant height of 26 cm.
Answers
Therefore, the volume of the cone is approximately 800π cubic centimeters, or approximately 2512.44 cubic centimeters when rounded to two decimal places.
What is volume?Volume is a measure of the amount of space occupied by a three-dimensional object or a substance. The volume of a solid object can be determined by measuring its dimensions, such as its length, width, and height, and applying an appropriate mathematical formula depending on its shape.
Here,
The volume of a cone can be calculated using the formula:
V = (1/3)πr²h
where r is the radius of the base, h is the height of the cone, and π is a constant equal to approximately 3.14. In this case, we are given the radius of the cone as 10 cm and the slant height as 26 cm. We can use the Pythagorean theorem to find the height of the cone:
h² = (slant height)² - (radius)²
h² = 26² - 10²
h² = 576
h = √576
h = 24
Now that we have the height of the cone, we can use the formula for the volume of a cone:
V = (1/3)πr²h
V = (1/3)π(10²)(24)
V = (1/3)π(100)(24)
V = (1/3)(2400π)
V = 800π

Verify that the two planes are parallel, and find the distance between the planes. (Round your answer to three decimal places.)
2X - 42 = 4
2x - 4z = 10
Answers
the distance between the two planes is |x - 19|. Since we don't have any information about the value of x, we cannot compute the exact distance. We can only give the answer in terms of |x - 19|, rounded to three decimal places.
To verify that the two planes are parallel, we need to check if their normal vectors are parallel. The normal vector of the first plane is <2, 0, 0> and the normal vector of the second plane is <2, 0, -4>. We can see that these vectors are parallel because they have the same direction but different magnitudes. Therefore, the two planes are parallel.
To find the distance between the planes, we can use the formula:
distance = |ax + by + cz + d| / √(a² + b² + c²)
where a, b, and c are the coefficients of the variables x, y, and z in the equation of one of the planes, and d is the constant term.
Let's use the first plane: 2x - 42 = 4
We can rewrite this as 2x - 38 = 0, which means that a = 2, b = 0, c = 0, and d = -38.
Substituting these values into the formula, we get:
distance = |2x + 0y + 0z - 38| / √(2² + 0² + 0²)
distance = |2x - 38| / 2
distance = |x - 19|
Therefore, the distance between the two planes is |x - 19|. Since we don't have any information about the value of x, we cannot compute the exact distance. We can only give the answer in terms of |x - 19|, rounded to three decimal places.

Answers
The area of the sign can be calculated by finding the area of the trapezoid shape. The formula for the area of a trapezoid is A = (1/2) * (base1 + base2) * height. In this case, the bases are 5.5 feet (half of 11 feet, which is the flat top of the five-sided figure) and 9 feet (the entire length of the image), and the height is 4 feet. Plugging these values into the formula, we get:
A = (1/2) * (5.5 + 9) * 4
A = (1/2) * 14.5 * 4
A = 7.25 * 4
A = 29
So, the area of the sign is 29 square feet.
The volume of a rectangular prism is calculated by multiplying its length, width, and height. In this case, the length is given as 71.5 inches, the width is given as 60 inches, and the volume is given as 43,972.5 in^3. We can solve for the height by dividing the volume by the product of the length and width:
Height = Volume / (Length * Width)
Height = 43,972.5 / (71.5 * 60)
Height ≈ 10.25 inches
So, the height needed to reach the desired volume is approximately 10.25 inches.
The area of the rectangular box face can be calculated by finding the length of the sides of the rectangle using the given coordinates, and then using the formula for the area of a rectangle, which is A = length * width. In this case, the length is the difference between the x-coordinates of the two points on the x-axis (4 - (-8) = 12) and the width is the difference between the y-coordinates of the two points on the y-axis (4 - (-2) = 6). Plugging these values into the formula, we get:
A = 12 * 6
A = 72
So, the area of the label needed to cover the face of the box is 72 square inches.
The perimeter of a rectangle is calculated by adding the lengths of all four sides. In this case, we can use the given coordinates of the four points to find the lengths of the sides. The length is the difference between the x-coordinates of the two points on the x-axis (3 - (-2) = 5) and the width is the difference between the y-coordinates of the two points on the y-axis (6 - (-3) = 9). Since the opposite sides of a rectangle have equal lengths, the perimeter is twice the sum of the length and width:
Perimeter = 2 * (Length + Width)
Perimeter = 2 * (5 + 9)
Perimeter = 2 * 14
Perimeter = 28
So, the perimeter of the rectangle created by the points is 28 units.
The volume of a rectangular prism is calculated by multiplying its length, width, and height. In this case, the length is given as 14.2 yards (14 and one-fifth yards), the width is given as 7 yards, and the height is given as 8 yards. Plugging these values into the formula, we get:
Volume = Length * Width * Height
Volume = 14.2 * 7 * 8
Volume ≈ 795.2
So, the volume of the rectangular prism is approximately 795.2 cubic yards. Answer: seven hundred ninety-five and one-fifth yd3
A whole wall is split in half and we painted half of the wall 3 colors what fraction of the wall does each color occupy?
Answers
The total fraction of the wall that has been painted is 1/2. If a whole wall is split in half and we painted half of the wall 3 colors, each color occupies 1/6 of the painted area.
To answer your question, we need to first determine the total fraction of the wall that has been painted. Since the wall has been split in half, we can say that the painted area covers half of the wall. Therefore, the total fraction of the wall that has been painted is 1/2.
Now, we need to divide this 1/2 fraction among the three colors that were used. Let's say the three colors are red, blue, and green. We can represent the fraction of the wall occupied by each color as follows:
- Red: 1/3 x 1/2 = 1/6
- Blue: 1/3 x 1/2 = 1/6
- Green: 1/3 x 1/2 = 1/6
So each color occupies 1/6 of the painted area, which is equivalent to 1/12 of the whole wall. This means that if the wall was not split in half and we painted the entire wall with the same 3 colors, each color would occupy 1/12 of the total wall area.
In summary, if a whole wall is split in half and we painted half of the wall 3 colors, each color occupies 1/6 of the painted area, which is equivalent to 1/12 of the whole wall.

The simplified form of the given expression is (x-7)/3x.
The given expression is (2x²-8x-42)/6x² ÷ (x²-9)/(x²-3x)
Here, (x²-4x-21)/3x² ÷ (x-3)(x+3)/x(x-3)
= (x²-4x-21)/3x² ÷ (x+3)/x
= (x²-4x-21)/3x² × x/(x+3)
= (x²-4x-21)/3x × 1/(x+3)
= (x²-4x-21)/3x(x+3)
= (x²-7x+3x-21)/3x(x+3)
= [x(x-7)+3(x-7)]/3x(x+3)
= (x-7)(x+3)/3x(x+3)

Answer:
(c) 12.5
Step-by-step explanation:
You want the unknown leg of a right triangle with one leg 10 and hypotenuse 16.
Sanity checkThe triangle inequality tells you the unknown leg of the triangle will have a length between the difference of the two known legs, and the longest leg of the triangle.
Since this is a right triangle, its longest leg is the hypotenuse. The unknown side cannot be longer than that, so must be less than 16.
The difference of the given lengths is ...
16 -10 = 6
so the missing leg must be longer than 6.
Only one answer choice is between 6 and 16: 12.5.
The missing leg length is 12.5 units.
__
Additional comment
If you want to figure the length, you can use the Pythagorean theorem:
c² = a² +b²
16² = 10² +b²
b² = 256 -100 = 156
b = √156 ≈ 12.49 ≈ 12.5
The length of the unknown leg is 12.5 units.

The calculated number of times you would expect to roll a three or a six is 32 times
How many times would you expect to roll a three or a six?From the question, we have the following parameters that can be used in our computation:
Cube = 96
In a cube, we have the following probability equation
P(3 or 6) = 1/6 + 1/6
When the sum is evaluated, we have
P(3 or 6) = 2/6
So, when the die is rolled 96 times, we have
Expected value = 2/6 * 96
Evaluate the products

A cuboid has a volume of 1815 cm³. Each side of the cuboid is a whole number of centimetres and each side is longer than 1 cm. Find all the possible dimensions of the cuboid
Answers
There are 4 possible sets of dimensions for the cuboid with a volume of 1815 cm³.
How to solve for the dimensionsFirst, find the prime factors of 1815:
1815 = 3 × 5 × 11 × 11
Now, we need to find all possible combinations of these factors into three whole numbers. Each combination of three numbers, when multiplied, should give 1815. We can do this by finding the different ways the prime factors can be distributed among the three dimensions:
3 × 5 × (11 × 11) = 15 × 121 (height × width × length)
3 × 11 × (5 × 11) = 33 × 55
5 × 11 × (3 × 11) = 55 × 33
11 × 11 × (3 × 5) = 121 × 15
We have found 4 different sets of dimensions for the cuboid:
15 × 121 × 1
33 × 55 × 1
55 × 33 × 1

Square oabc is drawn on a centimetre grid.o is (0,0) a is(3,0) b is(3,3) c is (0,3)write down how many invariants points there are on the perimeter of the square when oabc is translated by the vector (1 3)
Answers
There are 4 invariant points on the perimeter of the square when oabc is translated by the vector (1 3).
To find the invariant points on the perimeter of the square when oabc is translated by the vector (1 3), we need to apply this translation to each vertex of the square and see which ones remain on the square.
If we add the vector (1 3) to each vertex, we get:
o + (1 3) = (1 3)
a + (1 3) = (4 3)
b + (1 3) = (4 6)
c + (1 3) = (1 6)
Now we need to check which of these points are still on the square. We can see that points (1 3) and (4 3) are on two adjacent sides of the square, and points (1 6) and (4 6) are on the other two adjacent sides.
Therefore, there are 4 invariant points on the perimeter of the square when oabc is translated by the vector (1 3). These invariant points are the points where the sides of the original square intersect with the sides of the translated square.

Answers
human hair to grow 20 inches, considering the length of hair is proportional to the number of months it has grown.
First, let's establish the proportionality constant, which is the average rate at which human hair grows. On average, human hair grows approximately 0.5 inches per month.
Now, let's find out how many months it takes for hair to grow 20 inches. We can set up a proportion equation as follows:
Length of hair (in inches) / Number of months = Proportionality constant
Let "x" be the number of months it takes for hair to grow 20 inches. We can write the equation as:
20 inches / x months = 0.5 inches/month
To solve for x, we can multiply both sides by x months, which gives us:
20 inches = 0.5 inches/month * x months
Now, we can divide both sides by 0.5 inches/month:
x months = 20 inches / 0.5 inches/month
x months = 40 months
So, it takes 40 months for human hair to grow 20 inches, considering the length of hair is proportional to the number of months it has grown.

5) If the price charged for a bolt is p cents, then x thousand bolts will be sold in a certain hardware store, where p = 82 - x 26 . How many bolts must be sold to maximize revenue?
Answers
To maximize the revenue, we need to find the maximum value of the revenue function.
The revenue function, R(x), is given by the product of the price per bolt (p) and the number of bolts sold (x thousand), which is R(x) = p * x.
Given the price function p = 82 - 26x,
we can substitute this into the revenue function:
R(x) = (82 - 26x) * x
Now, we need to find the maximum value of R(x). We'll do this by taking the derivative of R(x) with respect to x and setting it to zero:
R'(x) = d/dx[(82 - 26x) * x] R'(x) = 82 - 52x
Now, we set R'(x) = 0 and solve for x: 0 = 82 - 52x 52x = 82 x = 82 / 52 x ≈ 1.58
So, approximately 1.58 thousand (or 1580) bolts must be sold to maximize revenue in the hardware store.

The height of the storage space is 6 feet. The length is 2 times the width. The volume of the storage is 48 cubic feet. What is the width and length of the storage space
Answers
Step-by-step explanation:
Let's use the formula for the volume of a rectangular prism, which is:
V = lwh
where V is the volume, l is the length, w is the width, and h is the height.
We are given that the height is 6 feet, and the volume is 48 cubic feet. Therefore, we can solve for the product of the length and width:
lw = V / h = 48 / 6 = 8
We are also given that the length is twice the width, so we can substitute 2w for l:
(2w)w = 8
Simplifying this equation, we get:
2w^2 = 8
Dividing both sides by 2, we get:
w^2 = 4
Taking the square root of both sides, we get:
w = 2
Therefore, the width of the storage space is 2 feet. Since the length is twice the width, the length is:
l = 2w = 2(2) = 4
So the length of the storage space is 4 feet.

Answers
Mrs. Vilakazi will make a profit of r233,88 if she bakes 204 scones and sells 171.
The profit is the difference between the total revenue and the total cost.
The total cost is the cost per scone multiplied by the number of scones baked:
total cost = r0,53/scone × 204 scones = r108,12
The total revenue is the selling price per scone multiplied by the number of scones sold:
total revenue = r2,00/scone × 171 scones = r342,00
Therefore, the profit is:
profit = total revenue - total cost
profit = r342,00 - r108,12
profit = r233,88
