Mr. Woods is buying ice cream for two of his students, Moses and Gaby. They each get one scoop of ice cream. Gaby wants ice cream in a cone, but she is a slow eater. Moses wants a cup because he is a bit messy and doesn’t want to drip any ice cream. Each scoop is a perfect sphere and has a radius of 5 cm. The height of the cup and cone are both 12 cm. and the radius of each container is the same as each scoop of ice cream.
the volume of one scoop of ice cream is 523.6 cc. The cup can hold a volume of 942.5 cc, which is more than one scoop of ice cream. Therefore, Moses's cup can hold one scoop of ice cream without overflowing or spilling.
let's break down the problem step by step.
First, we need to calculate the volume of one scoop of ice cream. Since each scoop is a perfect sphere with a radius of 5 cm, we can use the formula for the volume of a sphere, which is:
V = (4/3)πr³
where V is the volume and r are the radius. Substituting r = 5 cm, we get:
V = (4/3)π(5³) = 523.6 cubic centimeters (cc)
So, the volume of one scoop of ice cream is 523.6 cc.
Next, we need to calculate the volume of the cup and the cone. Since both have the same radius as the scoop of ice cream, we can use the formula for the volume of a cylinder and a cone, respectively, with height 12 cm and radius 5 cm:
For the cup:
[tex]V_{cup}[/tex]= πr²h = π(5²) (12) = 942.5 cc
For the cone:
[tex]V_{cone}[/tex] = (1/3)πr²h = (1/3)π(5²)(12) = 314.2 cc
So, the volume of the cup is 942.5 cc, and the volume of the cone is 314.2 cc.
Now, we can determine how much ice cream each container can hold. Since each person gets one scoop of ice cream, we need to compare the volume of one scoop of ice cream to the volume of each container.
For Gaby's cone:
We know that the volume of one scoop of ice cream is 523.6 cc. The cone can hold a volume of 314.2 cc, which is less than one scoop of ice cream. Therefore, Gaby's cone can only hold one scoop of ice cream.
For Moses's cup:
Again, the volume of one scoop of ice cream is 523.6 cc. The cup can hold a volume of 942.5 cc, which is more than one scoop of ice cream. Therefore, Moses's cup can hold one scoop of ice cream without overflowing or spilling.

PLS HELP Triangle ABC
maps to triangle XYZ
by a rotation of 90∘
counterclockwise about the origin followed by a reflection across the line y=x.
In triangle ABC,
m∠A=45∘,
m∠B=55∘,
and m∠C=80∘.
What is the measure of ∠Y?
Enter your answer as the correct value, like this: 42
Based on the given information, the measure of angle Y is 30 degrees.
What is transformation?A transformation is a process or operation that changes the position, shape, or orientation of a geometric figure or an object in space.
There are several types of transformations, including:
Rotation: A transformation that rotates a figure around a fixed point, called the center of rotation, by a certain angle.
Reflection: A transformation that produces a mirror image of a figure across a line, called the line of reflection.
To start, let's first find the vertices of triangle XYZ after the given transformations:
Rotation of 90 degrees counterclockwise about the origin:
The rotation of point (x, y) by 90 degrees counterclockwise about the origin gives us the point (-y, x). So we can apply this transformation to each vertex of triangle ABC to get the vertices of triangle XYZ after rotation:
A = (cos(45), sin(45)) = (√2/2, √2/2) → A' = (-√2/2, √2/2)
B = (cos(55), sin(55)) → B' = (-sin(55), cos(55))
C = (cos(80), sin(80)) → C' = (-sin(80), cos(80))
Reflection across the line y=x:
To reflect a point (x, y) across the line y=x, we simply swap the x and y coordinates to get (y, x). So we can apply this transformation to each vertex of triangle XYZ to get the final vertices:
A'' = (√2/2, -√2/2)
B'' = (cos(55), -sin(55))
C'' = (cos(80), -sin(80))
Now we can use the law of cosines to find the measure of angle Y:
cos(Y) = [B''C''² + A''C''² - A''B''²] / [2 * B''C'' * A''C'']
= [cos(55)² + cos(80)² - (√2/2)²] / [2 * cos(55) * cos(80)]
≈ 0.866
So we have cos(Y) = 0.866, which means Y ≈ 30 degrees. Therefore, the measure of angle Y is approximately 30 degrees.

Find the maximum value of = √ subject to the cost constraint K + 4L = 16.
Estimate the change in the optimal value of Q if the cost constraint is changes to K +
4L = 17
The maximum value of Q was found to be 26.49 subject to the cost constraint K+4L=16.2, and the optimal value of Q decreased by approximately 9.39 when the cost constraint was changed to K+4L=17.
To find the maximum value of Q subject to the cost constraint, we can use the method of Lagrange multipliers. We first define the Lagrangian function:
L(K, L, λ) = 10√(KL) + λ(K + 4L - 16.2)
where λ is the Lagrange multiplier.
∂L/∂K = 5√(L/K) + λ = 0
∂L/∂L = 5√(K/L) + 4λ = 0
∂L/∂λ = K + 4L - 16.2 = 0
K = 3.24, L = 2.16, λ = -2.5
Therefore, the maximum value of Q is:
Q = 10√(3.24*2.16) = 10√7.0224 ≈ 26.49
If the cost constraint is changed to K+4L=17, we can repeat the same process with the new constraint to get:
K = 4.25, L = 0.6875, λ = -2.5
Therefore, the new maximum value of Q is:
Q = 10√(4.25*0.6875) = 10√2.9297 ≈ 17.10
The change in the optimal value of Q is then:
17.10 - 26.49 ≈ -9.39
The optimal value of Q decreases by approximately 9.39 when the cost constraint is changed from K+4L=16.2 to K+4L=17. This indicates that the optimal value of Q is sensitive to changes in the cost constraint.

What is division?
Division is a basic arithmetic operation in mathematics that involves dividing one number by another. It is denoted by the symbol "/", or by the horizontal fraction bar. The number being divided is called the dividend, while the number it is being divided by is called the divisor. The result of the division is called the quotient. For example, if we divide 10 by 2, the dividend is 10, the divisor is 2, and the quotient is 5. The formula for division is:
dividend / divisor = quotient
In some cases, division may result in a remainder. For example, if we divide 10 by 3, the quotient is 3 with a remainder of 1. This can be expressed as 10 / 3 = 3 remainder 1, or as a mixed number, 3 1/3. In other cases, the division may result in a decimal or a fraction.
Here,
1) To divide (x² + 6x + 9) by (x + 3), we can use polynomial long division as follows:
x + 3 | x² + 6x + 9
- x² - 3x
-------
3x + 9
3x + 9
-----
0
Therefore, the quotient is x + 3 , dividend is x² + 6x + 9, divisor is (x+3) and the remainder is 0.
So, (x² + 6x + 9) = (x+3)×(x-3) + 0
2) To divide (x² - 9x + 18) by (x - 6), we can use polynomial long division as follows:
x - 6 | x² - 9x + 18
- x² + 6x
-------
-15x + 18
-15x + 90
--------
-72
Therefore, the quotient is x - 3, dividend is (x² - 9x + 18), divisor is x-6 and the remainder is -72.
So, (x² - 9x + 18) = (x-6)×(x-3) + (-72)
3) To divide (x² + 4x - 7) by (x + 5), we can use polynomial long division as follows:
x + 5 | x² + 4x - 7
- x² - 5x
-------
-x - 7
-x - 5
------
-2
Therefore, the quotient is (-x + -1), dividend is x² + 4x - 7, divisor is x+5 and the remainder is -2.
So, (x² + 4x - 7) = (-x-1)×(x+5) + (-2)

What did Archimedes discover in the bath? Why was he so excited? Describe the discovery using geometric terms. What do you predict Archimedes did next with his new discoveries? Explain.
According to the popular legend, Archimedes discovered a principle of buoyancy while taking a bath.
what was his discovery ?
He realized that the volume of water displaced by his body was equal to the volume of his body. This insight led him to formulate the principle of buoyancy, which states that an object placed in a fluid experiences an upward force equal to the weight of the fluid it displaces.
Archimedes was reportedly so excited by this discovery that he ran through the streets of Syracuse shouting "Eureka!" (meaning "I have found it" in Greek). This principle has numerous practical applications, including in shipbuilding and the design of submarines and other underwater vehicles.
In geometric terms, the principle of buoyancy can be explained using the concept of displacement. When an object is submerged in a fluid, it displaces a certain volume of fluid, which is equal to the volume of the object. This volume of fluid has weight, and the fluid exerts an upward force on the object that is equal to the weight of the displaced fluid. This is what causes objects to float in water or other fluids, as long as their weight is less than the weight of the fluid they displace.
As for what Archimedes did next with his new discoveries, it's difficult to say for certain, as there are many stories and legends about his life. However, we do know that he was a prolific inventor and mathematician, and he likely continued to explore the implications of his principle of buoyancy and other discoveries. He may have also used this principle in his work as an engineer and designer, creating new machines and devices that were more efficient and effective thanks to his insights into fluid mechanics.

The linear equation that represents the cost of visiting the gym x times is: y = 2x + 25
What is Algebraic expression ?
An algebraic expression is a mathematical phrase that can contain variables, constants, and operators (such as addition, subtraction, multiplication, and division) that are used to represent quantities and their relationships.
The cost of joining a gym includes an initial fee of $25 and then $2 per visit. Let y be the total cost of visiting the gym x times.
To find the equation that represents this relationship, we need to determine the slope and the y-intercept.
The slope represents the rate of change of the cost with respect to the number of visits, which is the cost per visit. Since the cost per visit is $2, the slope is 2.
The y-intercept represents the initial cost of joining the gym, which is $25.
Therefore, the linear equation that represents the cost of visiting the gym x times is: y = 2x + 25
In this equation, x represents the number of visits to the gym, and y represents the total cost of those visits.

Solve the system by substitution
if you get a decimal round to the nearest hundred
We can use the quadratic formula to solve for x, and the system of equations to solve for y. We have two possible solutions for x: x = 4 + [tex]\sqrt{28}[/tex] ≈ 8.29, and y = 7 - x ≈ -0.29.
What is substitution method?A system of linear equations can be solved using the substitution approach. In this procedure, one variable in one of the equations is solved in terms of the other, and that expression is then replaced into the other equation. This yields an equation with a single variable that can be solved. Once one variable has been identified, it may be swapped into one of the original equations to determine the second variable.
We can use the first equation to solve for one of the variables in terms of the other, and then substitute that expression into the second equation to get an equation in just one variable. Let's solve the first equation for y:
x + y = 7
y = 7 - x
Now we can substitute this expression for y into the second equation:
[tex]y = x^2 - 9x - 5[/tex]
[tex]7 - x = x^2 - 9x - 5[/tex]
Rearranging terms, we get:
[tex]x^2 - 8x - 12 = 0[/tex]
Now we can use the quadratic formula to solve for x:
x = (-b ± [tex]\sqrt{(b^2 - 4ac)}[/tex]) / 2a
where a = 1, b = -8, and c = -12. Plugging these values in, we get:
x = (-(-8) ± [tex]\sqrt{(-8)^2 - 4(1)(-12))}[/tex]) / 2(1)
Simplifying:
x = (8 ± [tex]\sqrt{(64 + 48)}[/tex]) / 2
x = (8 ± [tex]\sqrt{(112)}[/tex]) / 2
x = 4 ± [tex]\sqrt{(28)}[/tex]
So we have two possible solutions for x:
x = 4 + [tex]\sqrt{(28)}[/tex] ≈ 8.29
x = 4 - [tex]\sqrt{(28) }[/tex]≈ -0.29
Now we can use either equation to solve for y. Let's use y = 7 - x:
When x = 4 + [tex]\sqrt{(28)}[/tex], we have:
y = 7 - (4 + [tex]\sqrt{(28)}[/tex]) = 3 - [tex]\sqrt{(28)}[/tex]
When x = 4 - [tex]\sqrt{(28)}[/tex], we have:

I’m doing some homework and I completely forgot how to do perimeter since 5th. Just answer the first question so I can understand it againn :’)
Answer:
You can start by changing 12 3/4 into a decimal, which would be 12.75.
The formula for perimeter of a rectangle is (l + w) x 2, so you could write it like this:
(12.75 + 6.4) x 2
Then solve the question in the parenthesis...
19.15 x 2 = 38.30
Now, the question says to write the perimeter into simplest fraction form.
38.30 = 38 3/10.
So, there you have it!
38 3/10 meters

The diagram shows the curve y = -x²-x+ 20.
(i) The curve cuts the x-axis at two points A and B, and the y-axis at the point C. Find the coordinates of A, B and C.
(ii) The point D(3, h) lies on the curve. Find the value of h.
Plotting the equation shows that the graph crosses the
y axis at A (-5, 0) and B (4, 0) and x axis at C (0, 20)The value of h is 8
How to find the value of hTo find the value of y when x is 3, we need to substitute 3 for x in the given equation -x^2 - x + 20:
y = -x^2 - x + 20 (substitute x = 3)
y = -(3)^2 - 3 + 20
y = -9 - 3 + 20
y = 8
Therefore, when x is 3, y is 8.

stretch by 2, left 4, down 1
stretch by 2, right 4, down 1
stretch by 2, right 3, down 1
O right 8, down 1
Answer:
stretch by 2, right 4, down 1
Step-by-step explanation:
In a function in the form:
f(x) = a(x - h)² + k
the number in front, a, shows vertical stretch (if its bigger than 1. Its a shrink or smash if its a fraction less than 1)
Horizontal shifts are shown in close next to the x, inside the parenthesis shown here with an h. Horizontals shifts are maybe the opposite of what you might think they should be. + anumber is a left shift and - anumber is a right shift.
Vertical shifts are shown by a number tacked onto the end of the equation, k These shifts are more intuitive. + anumber shifts up and - anumber shifts down.
For your equation:
f(x) = 2(x-4)²-1
The 2 is a vertical stretch. The -4 by the x is a right shift 4. The -1 tacked into the end is a shift down 1
Peter makes a weekly payment of $56.74 towards the mortgage. He need to make payments for 85 weeks to pay off the loan. Estimate the total amount Peter will pay back.
Round each weekly payment to the nearest whole dollar before calculating.
Answer: $4845
Step-by-step explanation:
First, round Peter's weekly payment to the nearest whole dollar:
$56.74 ≈ $57
Next, multiply the rounded weekly payment by the number of weeks he needs to make payments:
$57 * 85 weeks = $4845
So, Peter will pay back an estimated total of $4845.
Find
1-The mid point
2-The slop
3-The length
4 - The equation
1) the midpoint of the line segment is (2, 2.5). 2) the slope of the line is -3.25. 3)the length of the line segment is approximately 13.60. 4) the equation of the line is y = -3.25x + 9.
what is slope ?
In mathematics, the slope of a line is a measure of its steepness, defined as the ratio of the vertical change (rise) between two points on the line to the horizontal change (run) between the same two points. It is often denoted by the letter "m".
In the given question,
To find the midpoint of the line segment that connects the points (4,-4) and (0,9), we use the midpoint formula:
Midpoint = ((x₁ + x₂)/2, (y1 + y₂)/2)
Midpoint = ((4 + 0)/2, (-4 + 9)/2)
Midpoint = (2, 2.5)
So the midpoint of the line segment is (2, 2.5).
To find the slope of the line that passes through the two given points, we use the slope formula:
Slope = (y₂ - Ly₁)/(x₂ - x₁)
Slope = (9 - (-4))/(0 - 4)
Slope = 13/-4
Slope = -3.25
So the slope of the line is -3.25.
To find the length of the line segment that connects the two given points, we use the distance formula:
Length = √((x₂ - x₁)² + (y₂ - y1)²)
Length = √((0 - 4)² + (9 - (-4))²)
Length = √(16 + 169)
Length = √(185)
Length ≈ 13.60
So the length of the line segment is approximately 13.60.
Now, we can use the point-slope formula to find the equation of the line that passes through the point (4,-4) with slope -3.25:
y - y1 = m(x - x₁)
y - (-4) = -3.25(x - 4)
y + 4 = -3.25x + 13
y = -3.25x + 9

Simplify: 5(y+2) +5(y-1)
Answer:
Step-by-step explanation:
To simplify 5(y+2) +5(y-1), we distribute the 5 to each term inside the parentheses, and then combine like terms as follows:
5(y+2) +5(y-1)
= 5y + 10 + 5y - 5 // Distribute the 5
= 10y + 5 // Combine like terms
Therefore, 5(y+2) +5(y-1) simplifies to 10y + 5.

The rectangular prism, which has sides measuring 12 feet, 14 feet, and 20 feet, has a surface area of 1376feet².
What does surface area mean?The space a two-dimensional flat surface occupies is the area. Its unit of measurement is the square. A three-dimensional object's surface area is the area occupied by its exterior surface. It is also measured in units².
We must first determine the surface area of each face of a rectangular prism with sides measuring 12 feet, 14 feet, and 20 feet before adding them all up.
Let's first determine the area of the top and bottom faces, which are both rectangles measuring 12 feet by 20 feet each:
480feet² is equal to 2 x (12 ft x 20 ft) for the top and bottom faces.
The front and back faces, which are both rectangles with measurements of 12 feet by 14 feet, can now be calculated as follows:
2 x (12 ft) x (12 ft) x (12 ft) = 336feet² is the area of the front and back faces.
Let's finally determine the area of the rectangles that make up the left and right faces, both of which measure 14 feet by 20 feet:
2 x (14 ft x 20 ft) = 560feet² is the area of the left and right faces.
We add up the areas of all six faces to determine the total surface area:
Overall surface area equals the sum of the areas on the top, bottom, front, and back, as well as the left and right faces.
Overall surface area equals 480feet² + 336feet² + 560feet² =1376 feet².
As a result, the rectangular prism with measurements of 12 feet, 14 feet, and 20 feet has a surface area of 1376 feet².

Blake collects stamps. He collected a total of 275 stamps. If 88% of the stamps he collected were foreign, how many other stamps did he collect?
If 88% of the stamps were foreign, then the remaining 12% must be domestic stamps.
To find out how many domestic stamps Blake collected, we can start by calculating what 12% of 275 is:
12% of 275 = 0.12 x 275 = 33
The remaining stamps are foreign stamps.
Therefore, Blake collected 33 domestic stamps.

The algebraic rule for a reflection over the y-axis is
Answer:
(x, y) → (-x, y)
Step-by-step explanation:
The coordinates of the points that make up the function are equal to (x, y).
If we reflect the function over the y-axis, the sign of the y-value stays the same due to still being on the same side of the x-axis. The x-value sign will be the opposite of its current value due to being reflected over the y-axis.
This leads us to the algebraic expression:
(x, y) → (-x, y)
