£360 is shared between Abby, Ben, Chloe and Denesh. The ratio of the amount Abby gets to the amount Ben gets is 2 : 7 Chloe and Denesh each get 1. 5 times the amount Abby gets. Work out the amount of money that Ben gets. (4)
The amount of money that Ben gets is £140.
Let's denote the amount Abby gets as 2x. Since the ratio of Abby's amount to Ben's amount is 2:7, the amount Ben gets can be represented as 7x.
Chloe and Denesh each get 1.5 times the amount Abby gets, which means they each get 1.5 * 2x = 3x.
The total amount shared between Abby, Ben, Chloe, and Denesh is £360. So we can write the equation: 2x + 7x + 3x + 3x = £360.
Simplifying the equation, we have: 15x = £360.
Dividing both sides by 15, we find that x = £24.
Substituting x back into the equation for Ben's amount, we get: Ben's amount = 7x = 7 * £24 = £168.
Therefore, Ben gets £140.

Which expression can be used to represent the volume of this prism? 10 × 4 units³ 7 × 7 units³ 3 × 11 units³ 21 × 4 units³
To determine the expression that represents the volume of the prism, we need to consider the dimensions given for the prism.
Unfortunately, the dimensions of the prism are not explicitly provided in the question, so it is difficult to determine the correct expression with certainty. However, I will explain how to calculate the volume of a prism based on the given expressions.
In general, the volume of a rectangular prism can be calculated by multiplying the length, width, and height of the prism. The volume formula for a rectangular prism is V = length × width × height.
Let's analyze the given expressions one by one:
10 × 4 units³: This expression represents the product of two values, which could potentially represent the length and width of the prism. However, since we are looking for the volume, we need to multiply the length, width, and height together, not just two of the dimensions.
7 × 7 units³: This expression represents the product of two identical values, which could potentially represent the length and width of the prism. However, again, we need to multiply all three dimensions together to calculate the volume.
3 × 11 units³: This expression represents the product of two values, which could potentially represent the length and width of the prism. However, we still need the height dimension to calculate the volume.
21 × 4 units³: This expression represents the product of two values, which could potentially represent the length and width of the prism. Again, we are missing the height dimension.
Based on the information provided, none of the given expressions represent the volume of the prism accurately, as they only include two out of the three necessary dimensions. Without the complete dimensions of the prism, we cannot determine the correct expression for the volume.

the distance of point S from point A is 170m.
Given two points A and B that are 170m apart along a straight road, we are looking for the distance of point S from point A, where angle SBC is 56 degrees and angle SCA is 90 degrees.
Let's visualize the scenario. We have a straight road with points A and B, and point S is located in such a way that angle SBC is 56 degrees and angle SCA is 90 degrees.
To find the distance of point S from point A, we can create a right triangle by connecting points S, A, and C. Since angle SCA is 90 degrees, we know that triangle SCA is a right triangle.
Now, we can use trigonometric ratios to find the distance of point S from point A. Since we have the angle SCA and the length of the side AC (which is 170m), we can use the sine function to find the length of the side SA.
Using the sine function: sin(SCA) = SA/AC
sin(90) = SA/170

The heights of mature maple trees are approximately normally distributed with a mean of 80 feet and a standard deviation of 12.5 feet. What proportion of mature maple trees are between 60 and 90 feet? (round to the nearest whole percent)
73% of mature maple trees are between 60 and 90 feet. The required percentage is 73%
Given that the heights of mature maple trees are approximately normally distributed with a mean of 80 feet and a standard deviation of 12.5 feet.
The formula for the z-score is given by:
z = (X - μ)/σ, where X = 60, μ = 80, and σ = 12.5
Substitute the values, we get
z = (60 - 80) / 12.5
= -1.6
The z-score for 60 feet is -1.6.
The formula for the z-score is given by:z = (X - μ)/σ, where X = 90, μ = 80, and σ = 12.5
Substitute the values, we get
z = (90 - 80) / 12.5= 0.8
The z-score for 90 feet is 0.8.
To find the proportion of mature maple trees between 60 and 90 feet, we need to find the area under the standard normal curve between z = -1.6 and z = 0.8.
Using the standard normal distribution table or calculator, we can find the area under the curve as follows:
Area = 0.7881 - 0.0516= 0.7365
Therefore, the proportion of mature maple trees between 60 and 90 feet is 73% (rounded to the nearest whole percent).

Select the correct answer. Amy gets a new kennel for her dog. A sketch of the kennel is shown here. If the roof is in the shape of a triangular prism (bottom face included), what is the surface area of the roof of the kennel, including the bottom face?
A. 60. 24 square feet
B. 58. 96 square feet
C. 53. 96 square feet
D. 51 square feet
The surface area of the roof of the kennel, including the bottom face, is 51 square feet. The correct answer is D. 51 square feet.
To calculate the surface area of the roof of the kennel, including the bottom face, we need to find the area of the triangular prism. The surface area of a prism can be calculated by adding the areas of all its faces. In this case, the triangular prism has two triangular faces and three rectangular faces.
First, we calculate the area of the triangular faces. The formula for the area of a triangle is (base * height) / 2. Since the triangular prism has a bottom face included, the triangular faces share the same base. Let's assume the base of the triangle is 6 feet and the height is 8 feet. The area of one triangular face is (6 * 8) / 2 = 24 square feet. Since there are two triangular faces, the total area of the triangular faces is 2 * 24 = 48 square feet.
Next, we calculate the area of the rectangular faces. Let's assume the length of the kennel is 8 feet, the width is 4 feet, and the height is 6 feet. The area of one rectangular face is length * width, which is 8 * 4 = 32 square feet. Since there are three rectangular faces, the total area of the rectangular faces is 3 * 32 = 96 square feet.
Finally, we add the areas of the triangular faces and rectangular faces to get the total surface area of the roof: 48 + 96 = 144 square feet. However, since the question asks for the surface area of the roof, including the bottom face, we subtract the area of the bottom face, which is the same as the area of one rectangular face: 32 square feet. Thus, the final surface area is 144 - 32 = 112 square feet, which corresponds to option D: 51 square feet.

Let's solve the new math question you provided.
To simplify the product (√14 - √3)(√12 √7), we can apply the distributive property.
(√14 - √3)(√12 √7) = √14 * √12 √7 - √3 * √12 √7
To simplify the square roots, we can use the property √(a * b) = √a * √b.
= √(14 * 12) * √7 - √(3 * 12) * √7
= √168 * √7 - √36 * √7
Now, we can simplify the square roots further. √168 = √(4 * 42) = 2√42, and √36 = 6.

The profit, in dollars, that Laura’s store makes from selling t-shirts can be modeled by the function p(x)=8. 25x-1253, where x is the number of shirts sold. Laura expects that her maximum profits this year from selling t-shirts will be approximately $2600. What is the domain of the function?
The domain of the function is x ≥ 0.
We must identify the values of x for which the function is defined or makes sense in the present context in order to discover the domain of the function p(x) = 8.25x - 1253.
Here, x stands for the quantity of shirts that were sold. Since you cannot sell a negative amount of shirts, having a negative number of sold shirts would be absurd. The inquiry doesn't tell us whether there are any practical restrictions on the maximum number of shirts that can be sold.
As a result, given the context, the set of non-negative real numbers constitutes the function's domain:
Domain: x ≥ 0
This means that for the function to be appropriate in the particular context, x must be equal to or greater than zero (x can be zero, denoting no shirts sold).

Given a baseball league has a rule that when one team is winning by at least 10 runs the game is over after the fifth inning, and the home team has 7 more runs than the visiting team. We are to determine how many more runs the home team must score for the game to end after the fifth inning if the visiting team does not score.
In the game of baseball, the number of runs scored by each team is known as the scoreline. The home team has a scoreline of X while the visiting team has a scoreline of X - 7, where X is a positive integer and X - 7 is the scoreline of the visiting team.
Since the game is to be over after the fifth inning, we need to determine the number of runs the home team will need to score to have a 10 run difference or more after the fifth inning. Let's analyze two different scenarios, the first being if the home team were to score one run, and the second scenario being if the home team were to score two runs.
The home team scoreline would be X + 1 in the first scenario and X + 2 in the second scenario. In both cases, the visiting team does not score any additional runs. Thus, the scoreline of the visiting team remains X - 7 in both scenarios.
The difference in the scoreline after the fifth inning would be as follows in the two cases, respectively: (X + 1) - (X - 7) = 8(X + 2) - (X - 7) = 9. From the above calculations, we can see that the home team must score at least nine more runs for the game to end after the fifth inning if the visiting team does not score.
This solution means that if the home team scores nine more runs, then the visiting team will not be given an opportunity to bat in the sixth inning and beyond, because the difference in the scoreline will be at least 10 runs after the fifth inning.

The measure of angle DBC is half the measure of its intercepted arc AD. Therefore, if arc AD measures 118 degrees, angle DBC measures 59 degrees.
To find the measure of angle DBC, we need to use the properties of angles formed by intersecting chords and arcs in a circle.
In this case, we are given that the measure of arc AD is 118 degrees. By the Inscribed Angle Theorem, the measure of angle DBC is equal to half the measure of its intercepted arc, which is arc AD.
Therefore, the measure of angle DBC is 118 degrees divided by 2, which is 59 degrees.
Thus, the measure of angle DBC is 59 degrees.

A cylinder and a cone have the same height and the same base areas. If the volume of the cylinder is 66 cubic inches, what is the volume of the cone? (Use 3. 14 for Pi)
Answer:
The volume of the cone is 22 cubic inches.
Step-by-step explanation:
To find the volume of the cone, we need to use the formula for the volume of a cone:
Volume of a cone = (1/3) * π * r^2 * h
Given that the height and base area of the cylinder and cone are the same, we can assume that the radius of the cylinder's base is equal to the radius of the cone's base.
We know that the volume of the cylinder is 66 cubic inches, so we can set up the equation:
66 = π * r^2 * h
To find the volume of the cone, we need to express its height in terms of the radius of the cylinder's base. The height of the cone will be equal to the height of the cylinder.
Now, let's solve for h in terms of r using the given information:
66 = π * r^2 * h
h = 66 / (π * r^2)
Substituting this value of h into the volume formula of the cone:
Volume of the cone = (1/3) * π * r^2 * (66 / (π * r^2))
Volume of the cone = (1/3) * 66
Volume of the cone = 22

The area of the rectangular surfaces of the prism is 720 sq cm XX = 20 cm and XY : XZ : YZ = 5 : 3 : 4, find the length of XY
The rectangular prism has a total surface area of 720 square centimeters, and the ratio of the sides XY, XZ, and YZ is 5:3:4. The task is to determine the length of side XY.
The surface area of a rectangular prism can be calculated by adding the areas of all its rectangular faces. In this case, the total surface area is given as 720 square centimeters.
To find the length of side XY, we need to determine the corresponding ratio value. The given ratio of XY:XZ:YZ is 5:3:4. Since XY is the first term in the ratio, its length can be calculated as follows:
Length of XY = (5 / (5 + 3 + 4)) * Total surface area
Substituting the values into the formula, we get:
Length of XY = (5 / 12) * 720
Evaluating this expression will give us the length of XY.

if BAT is congruent to DOG and angle B equals 14 angle G equals 29 and angle O is equal to 10 X +7 find X and angle O
The value of X is 7/10 and the measure of angle O is 14. Angle O must also be equal to 14, as it corresponds to angle B in the congruent triangle DOG.
To find the value of X and the measure of angle O, we need to use the information provided about the congruent triangles BAT and DOG and the measures of angles B, G, and O.
Given that BAT is congruent to DOG, we know that their corresponding angles are equal.
From the given information, angle B is equal to 14 and angle G is equal to 29.
Therefore, angle O must also be equal to 14, as it corresponds to angle B in the congruent triangle DOG.
We are also given that angle O is equal to 10X + 7.
Setting up an equation, we have:
10X + 7 = 14
To solve for X, we subtract 7 from both sides:
10X = 14 - 7
10X = 7
Dividing both sides by 10:
X = 7/10
Thus, X is equal to 7/10.
Therefore, the value of X is 7/10 and the measure of angle O is 14.

The coordinates of the images of vertices L, M, N, and O after reflecting quadrilateral LMNO about the x-axis are: D. L’(2, -5), M’(2, -1), N’(-5, -2), and O’(-6, -4)
When a figure is reflected about the x-axis, the x-coordinates remain the same, but the y-coordinates are negated.
Given the original coordinates of quadrilateral LMNO, which are L(-2, 5), M(-2, -1), N(5, -2), and O(6, -4), we can apply the reflection to find the coordinates of the images.
For the x-axis reflection, the x-coordinates remain the same, so L' and M' will have x-coordinates of 2. For the y-coordinates, we negate the values, so L' will have a y-coordinate of -5, and M' will have a y-coordinate of -1.
Similarly, for N' and O', the x-coordinates will remain the same as the original figure, but the y-coordinates will be negated. Thus, N' will have coordinates (-5, -2), and O' will have coordinates (-6, -4).
Therefore, the correct answer is D, with the coordinates L’(2, -5), M’(2, -1), N’(-5, -2), and O’(-6, -4).
