Answers

Answer 1

When the base of a triangle is doubled, the height must be halved to maintain the same area. This is because the area of a triangle is proportional to the product of its base and height. Area of the new triangle is b₁h₂.

Given that a triangle has base b and height h, and the base is doubled. We need to find how the height must change so that the area remains the same.

The area of the original triangle is (1/2) b₁h₁.

Let's assume that the original base is b₁ and the original height is h₁.

Now, the base is doubled, so the new base is 2b₁.

Using the formula for the area of a triangle, we can find the area of the new triangle as

Area of the new triangle = (1/2) × base × height

= (1/2) × 2b₁ × h₂

= b₁h₂

where h₂ is the new height of the triangle.

Since we want the area of the new triangle to be equal to the area of the original triangle, we can equate the two expressions for the area

b₁h₁ = b₁h₂

Simplifying, we get

h₂ = h₁/2

Therefore, the height must be halved when the base is doubled to keep the area of the triangle constant.

game?


From the collected data, what


is the median number of


rebounds Jamie had for her


final 10 games?

Answers

Step-by-step explanation:

1. To find the mean number of rebounds Jamie had per game, we need to add up all the rebounds she had and then divide by the total number of games played:

Mean = (8 + 12 + 8 + 11 + 15 + 6 + 9 + 8 + 10 + 13) / 10

Mean = 100 / 10

Mean = 10

Therefore, the mean number of rebounds Jamie had per game was 10.

2. To find the median number of rebounds Jamie had for her final 10 games, we need to first arrange the data in order from least to greatest:

6, 8, 8, 8, 9, 10, 11, 12, 13, 15

Since there are an even number of data points, the median will be the average of the two middle values, which are 9 and 10:

Median = (9 + 10) / 2

Median = 9.5

Therefore, the median number of rebounds Jamie had for her final 10 games was 9.5.

There are (2a+b) books in a pile. The thickness of each book is 2cm. Find the height of the pile of books in terms of a and b, expressing the answer in the expanded form

Answers

The height of the pile of books in terms of a and b is 4a cm + 2b cm.

To find the height of the pile of books in terms of a and b, we need to multiply the number of books by the thickness of each book. Since there are (2a+b) books in the pile and the thickness of each book is 2cm, the height of the pile can be expressed as:

(2a+b) x 2cm

Expanding this expression, we get:

4a cm + 2b cm

Therefore, the height of the pile of books in terms of a and b is 4a cm + 2b cm. This means that for every additional 'a' book, the height of the pile will increase by 4cm and for every additional 'b' book, the height of the pile will increase by 2cm.

It's important to note that this formula assumes that all the books are the same size and have the same thickness. If there are any variations in size or thickness, the formula may not accurately represent the height of the pile. Additionally, it's important to ensure that all units of measurement are consistent (in this case, cm for both the thickness of the book and the height of the pile).

The equation of the ellipse is x^2/9 + y^2/6.75 = 1

Finding the equation of the ellipse

To find the equation of an ellipse, we need to know the center, the major and minor axis, and the foci.

Since we are given the eccentricity and foci, we can use the following formula:

c = (1/2)a

Since the foci are (0, +/-3), the center is at (0, 0). We know that c = 3/2, so we can find a:

c = (1/2)a

3/2 = (1/2)a

a = 3

The distance from the center to the end of the minor axis is b, which can be found using the formula:

b = √(a^2 - c^2)

b = √(3^2 - (3/2)^2)

b = √6.75

So the equation of the ellipse is:

x^2/a^2 + y^2/b^2 = 1

Plugging in the values we found, we get:

x^2/3^2 + y^2/6.75 = 1

Simplifying:

x^2/9 + y^2/6.75 = 1

Therefore, the equation of the ellipse is x^2/9 + y^2/6.75 = 1

A rectangular garden has an area of 100 square meters. The length of the garden is 10 meters more than the width. What is the perimeter of the garden?

Answers

Answer:

40 meters

Step-by-step explanation:

Let's assume the width of the garden is x meters, then the length of the garden would be (x+10) meters since we know that the length is 10 meters more than the width.

We also know that the area of the garden is 100 square meters, therefore:

Area = Length x Width

100 = (x+10) x x

Expanding the equation we get:

100 = x^2 + 10x

Rearranging the terms we have:

x^2 + 10x - 100 = 0

Solving for x using the quadratic formula, we get:

x = 5 or x = -20

Since the width cannot be negative, we discard the negative solution and conclude that the width of the garden is 5 meters. Therefore, the length of the garden is (5+10) = 15 meters.

The perimeter of the garden is the sum of the four sides, which is:

Perimeter = 2 x (Length + Width)

Perimeter = 2 x (15 + 5)

Perimeter = 2 x 20

Perimeter = 40 meters

Therefore, the perimeter of the garden is 40 meters.

Answer:

Let's start by using algebra to solve for the width of the garden:

- Let w be the width of the garden.

- Then the length of the garden is w + 10.

- The area of the garden is length x width, so we can write the equation: (w + 10)w = 100.

- Expanding the left side of the equation, we get: w^2 + 10w = 100.

- Rearranging the equation, we get: w^2 + 10w - 100 = 0.

- Factoring the left side of the equation, we get: (w + 20)(w - 10) = 0.

- Solving for w, we get: w = -20 or w = 10. Since the width cannot be negative, we have w = 10.

Now that we know the width of the garden is 10 meters, we can find the length by adding 10 meters:

- Length = width + 10 = 10 + 10 = 20 meters.

Finally, we can find the perimeter of the garden by adding up the lengths of all four sides:

- Perimeter = 2(length + width) = 2(20 + 10) = 2(30) = 60 meters.

Therefore, the perimeter of the garden is 60 meters.

Step-by-step explanation:

The quantity of a substance can be modeled by the function R(t) that satisfies the differential equation dR/dt= -1/5(R – 20). One point on this function is R(2) = 35. Based on this model, use a linear approximation to the graph of Rat t = 2 to estimate the quantity of the substance at t 1.9. \

Answers

The estimated quantity of the substance at t = 1.9 is approximately 35.3 units.

To estimate the quantity of the substance at t = 1.9 using linear approximation, we can use the formula:

ΔR ≈ dR/dt * Δt

Given the point R(2) = 35 and the differential equation dR/dt = -1/5(R – 20), we can first find the value of dR/dt at t = 2.

dR/dt(2) = -1/5(R(2) – 20) = -1/5(35 – 20) = -1/5(15) = -3

Now, we can calculate Δt, which is the difference between the given t-value (2) and the desired t-value (1.9):

Δt = 1.9 - 2 = -0.1

Next, we can calculate ΔR using the linear approximation formula:

ΔR ≈ dR/dt * Δt ≈ -3 * (-0.1) = 0.3

Finally, we can estimate the quantity of the substance at t = 1.9 by adding ΔR to the given value of R(2):

R(1.9) ≈ R(2) + ΔR ≈ 35 + 0.3 = 35.3

Therefore, the estimated quantity of the substance at t = 1.9 is approximately 35.3 units.

where (x1, y1) and (x2, y2) are the coordinates of the two points, and d is the distance between them.

Using the given coordinates of the two points, we have:

x1 = -2, y1 = 7

x2 = -5, y2 = 9

Substituting these values into the distance formula, we get:

d = √[(-5 - (-2))² + (9 - 7)²]

d = √[(-3)² + 2²]

d = √(9 + 4)

488 green tickets, 523 yellow tickets, and 331 red tickets have been sold. at the drawing, one ticket of each color will


be drawn, and four identical prizes will be awarded. which color ticket would you buy? explain your answer.

Answers

Buy yellow or green ticket for best chance of winning.

Which color ticket to buy?

To determine which color ticket to buy, we need to calculate the probability of winning with each color.

First, we need to determine the total number of possible combinations of one ticket of each color. This can be calculated by multiplying the number of tickets of each color together:

Total number of possible combinations = 369 x 488 x 523 x 331 = 39,123,833,144

Next, we need to determine the probability of winning with each color. Since there are four identical prizes, the probability of winning with any one color is the same. We can calculate the probability of winning with a specific color by dividing the number of tickets of that color by the total number of possible combinations:

Probability of winning with blue ticket = 369 / 39,123,833,144 ≈ 0.00000943

Probability of winning with green ticket = 488 / 39,123,833,144 ≈ 0.00001248

Probability of winning with yellow ticket = 523 / 39,123,833,144 ≈ 0.00001337

Probability of winning with red ticket = 331 / 39,123,833,144 ≈ 0.00000846

From the calculations above, we can see that the highest probability of winning is with the yellow ticket, followed closely by the green ticket. Therefore, if we want to maximize our chances of winning one of the prizes, we should buy the yellow or green ticket.

It's important to note that the difference in probabilities between the yellow and green tickets is very small, so the decision of which color to choose ultimately depends on personal preference.

Therefore, the number of different waffle cone options that James has is:

5 x 4 = 20

So, James has 20 different waffle cone options if he chooses a different flavor of ice cream for each scoop.

What is the approximate area of the triangle?





A. 12. 5 square units


B. 18 square units


C. 21. 5 square units


D. 31 square units

Answers

The approximate area of the triangle is 21. 5 square units (option c).

Triangles are three-sided polygons that can have different shapes and sizes. Now, let's focus on your question about finding the area of a triangle.

To begin with, the area of a triangle is given by the formula:

Area = (base × height) ÷ 2

where the base is the length of the side that is perpendicular to the height. The height, on the other hand, is the distance between the base and the opposite vertex.

In your problem, the base of the triangle is given as 7 units, and the height is given as 6.1 units. So, we can substitute these values into the formula to get:

Area = (7 × 6.1) ÷ 2

Area = 21.35 square units

Therefore, the approximate area of the triangle is 21.35 square units. In the answer choices provided, the closest option is C, which is 21.5 square units.

What can be the universal sets from which the following substes can be formed? a) set of cricket players of class 9.
b)set of cricket players of the school.
c)The set of odd numbers less than 10.​

Answers

The only option that represents the universal set from the subsets is:

B: A set of cricket players of the school.

How to identify the universal set?

The universal set is defined as a set that is said to consist of all the elements or objects, which includes its own elements. This universal set is represented by just a symbol 'U'

Now, a subset is also defined as a part of the universal set which is basically a group under the universal set.

Now, from the given options, the only one that could possible represent a universal set of all the options given is "a set of cricket players of the school."

Therefore we conclude that Option B provides the correct answer to the universal set definition.

Find the surface area of the square pyramid (above) using its net (below).

Answers

The surface area of the square pyramid is approximately 41.83 cm².

To start with, let's define a square pyramid.

The slant height of the pyramid can be found using the formula:

l = √(h² + (s/2)²)

where h is the height of the pyramid and s is the length of one side of the base.

Plugging in the given values, we get:

l = √(7² + (4/2)²) = √(57)

Now that we know the slant height, we can find the area of each triangular face using the formula:

A = (1/2)bh

where b is the base of the triangle, and h is the height of the triangle.

Plugging in the given values, we get:

A = (1/2)(4)(√(57)) = 2√(57)

Since there are four triangular faces, the total area of all the triangular faces is:

4A = 8√(57)

Finally, we can find the total surface area of the pyramid by adding the area of the square base to the area of all the triangular faces:

surface area = 16 + 8√(57) = approximately 41.83 cm²

Javier and ellema both get there cars wash and filled there gas tanks at the same gas station javier pays 26. 96 for a car wash and 5. 6 gallon of gas. Ellema pays 48. 62 for a car wash and 13. 2 gallons of gas

Answers

We can start by finding the cost per gallon of gas for each person:

Javier: 5.6 gallons of gas for $26.96, so cost per gallon = 26.96/5.6 = $4.79/gallon

Ellema: 13.2 gallons of gas for $48.62, so cost per gallon = 48.62/13.2 = $3.68/gallon

Now we can find the cost of just the car wash for each person:

Javier: $26.96 - (5.6 gallons * $4.79/gallon) = $-1.344, which doesn't make sense. It's possible there was a mistake in the numbers given.

Ellema: $48.62 - (13.2 gallons * $3.68/gallon) = $1.958, which also doesn't make sense. There may be an error in the given information.

The matrix that represents a dilation by a factor of 3 followed by a reflection over the horizontal axis is given as follows:

[tex]\left[\begin{array}{cc}3&0\\0&-3\end{array}\right][/tex]

What is a dilation?

A dilation can be defined as a transformation that multiplies the distance between every point in an object and a fixed point, called the center of dilation, by a constant factor called the scale factor.

The scale factor for this problem is given as follows:

k = 3.

Hence the matrix is:

[tex]\left[\begin{array}{cc}3&0\\0&3\end{array}\right][/tex]

For the reflection over the horizontal axis, we have that the y-coordinate is multiplied by -1, hence the matrix rule is:

[tex]\left[\begin{array}{cc}3&0\\0&-3\end{array}\right][/tex]
