What is the mean of 9, 10, 6, and 7 ?
These are the numbers of cubes in the original stacks.

The answer is correct, we can plot both triangles on a Coordinate plane and visually inspect the result. If we plot triangle ABC with vertices A(-3, 3), B(0, 4), and C(-3, 0), and then plot the image triangle A'B'C' with vertices A'(-3, -1), B'(0, 0), and C'(-3, -4), we can see that the image is a translation of the original triangle down by 4 units.

To determine the coordinates of the vertices of the image of triangle ABC after being translated 4 units down, we need to subtract 4 from the y-coordinates of each vertex. This is because a translation is a type of transformation that moves each point of a figure a certain distance in a certain direction.

So, starting with the preimage of triangle ABC with vertices at A(-3, 3), B(0, 4), and C(-3, 0), we can find the image by subtracting 4 from the y-coordinates:

A'(-3, 3 - 4) = A'(-3, -1)

B'(0, 4 - 4) = B'(0, 0)

C'(-3, 0 - 4) = C'(-3, -4)

Therefore, the coordinates of the vertices for the image after the translation are A'(-3, -1), B'(0, 0), and C'(-3, -4).

So, the correct option is A) A′(−3, −1), B′(0, 0), C′(−3, −4).

To check if the answer is correct, we can plot both triangles on a coordinate plane and visually inspect the result. If we plot triangle ABC with vertices A(-3, 3), B(0, 4), and C(-3, 0), and then plot the image triangle A'B'C' with vertices A'(-3, -1), B'(0, 0), and C'(-3, -4), we can see that the image is a translation of the original triangle down by 4 units.

Janet had 10 5/6 leftover birthday cakes in her deli at the end of the week. To determine how many remained after the donation, we need to subtract the number of cakes donated from the initial quantity.

To subtract fractions, we need to have a common denominator. The common denominator of 6 and 3 is 6, so we convert the fractions to have a denominator of 6.

10 5/6 can be written as (10 * 6 + 5) / 6 = 65/6.

5 2/3 can be written as (5 * 3 + 2) / 3 = 17/3.

Subtracting 17/3 from 65/6, we need to find a common denominator of 6 and multiply the numerators accordingly.

(65/6) - (17/3) = (65/6) - (34/6) = 31/6.

Therefore, 31/6 birthday cakes remained at Janet's deli at the end of the week, which can be simplified to 5 1/6 cakes.

Suppose Sipho has x marbles. According to the given information, Mark has 3 times more marbles than Sipho, so Mark has 3 times more marbles.

If Mark gives Sipho 17 marbles, Mark will be left with (3x - 17) marbles. And this will be twice as many Sipho particles, i.e. x.

Therefore, we can write the equation:

3x - 17 = 2x

To solve x, we subtract 2x on both sides of the equation:

3x - 2x - 17 = 0

Simplify the equation:

x - 17 = 0

Added 17 to both sides:

x = 17

So Sipho has 17 marbles. Since Mark has 3 times as many marbles as Sipho, Mark has 3 * 17 = 51 marbles.

So Sipho has 17 marbles and Mark has 51 marbles.

To find the area of a circle, we do πr^2. For circumference, we do 2πr, where r is the radius. Since we know the diameter of this circle is 12, and we know the radius is half the diameter, then:

12/2 = 6 = r

knowing r, we can find out the area and the circumference. The area is:

πr^2 = π 6^2, so it is 36π for the area. The circumference is:
2πr = 2 π 6 = 12π.

The maximum number of hikers who could have walked between 7 and 18 miles is 7.

To determine the minimum and maximum number of hikers who could have walked between 7 miles and 18 miles, we need to analyze the given frequency distribution. Let's break it down step by step.

a) Minimum number of hikers: To find the minimum number of hikers who could have walked between 7 miles and 18 miles, we need to consider the minimum values of each interval.

Looking at the table, we see that the 7-mile distance falls into the second interval (5 < x ≤ 10), which has a frequency of 3. Therefore, a minimum of 3 hikers could have walked 7 miles.

Similarly, the 18-mile distance falls into the third interval (10 < x ≤ 15), which has a frequency of 8. Therefore, a minimum of 8 hikers could have walked 18 miles.

Since we are interested in the number of hikers who walked between 7 and 18 miles, we take the maximum value of the two intervals: 8.

Therefore, the minimum number of hikers who could have walked between 7 and 18 miles is 8.

b) Maximum number of hikers: To find the maximum number of hikers who could have walked between 7 miles and 18 miles, we need to consider the maximum values of each interval.

Looking at the table, we see that the 7-mile distance falls into the third interval (5 < x ≤ 10), which has a frequency of 8. Therefore, a maximum of 8 hikers could have walked 7 miles.

Similarly, the 18-mile distance falls into the fourth interval (10 < x ≤ 15), which has a frequency of 7. Therefore, a maximum of 7 hikers could have walked 18 miles.

Since we are interested in the number of hikers who walked between 7 and 18 miles, we take the minimum value of the two intervals: 7.

Therefore, the maximum number of hikers who could have walked between 7 and 18 miles is 7.

Answer:

  41.12 square units

Step-by-step explanation:

You want the area of the attached figure showing a triangle of height 4 atop a semicircle of diameter 8.

The area of a triangle is given by ...

  A = 1/2bh

where b is the base and h is the height.

The area of a semicircle is given by ...

  A = (π/2)r²

where r is the radius, half the diameter.

The figure shows a triangle with a base of 8 units and a height of 4 units. Its area is ...

  A = 1/2(8)(4) = 8·2 = 16

The semicircle has a radius of 4, so its area is ...

  A = π/2(4²) = 8π ≈ 25.12

Then the total area of the figure is ...

  triangle area + semicircle area = 16 +25.12 = 41.12 square units

__

Additional comment

Since the triangle and the semicircle have the same width, we can sum the "equivalent" heights of each and consider the result as a rectangle. You are familiar with the fact that a triangle has half the area of a rectangle the same height, so a triangle of height 4 is equivalent to a rectangle of height 4/2 = 2.

Similarly, the equivalent height of the semicircle can be found to be π/4 times its radius. Here, the radius is 4 units, so the semicircle of diameter 8 is equivalent to a rectangle 8 units by 4(π/4) = π units.

This means the entire figure is equivalent to a rectangle 8 units wide and (2+π) units high. That is the calculation shown in the attachment.

To eliminate one of the variables by adding a multiple of one equation to the other, you should multiply the equation containing the variable you want to eliminate by a suitable multiplier.

Let's assume you want to eliminate the variable y. In this case, you should multiply the equation containing y by a multiplier that will make the coefficient of y in one equation equal to the negative coefficient of y in the other equation. This will ensure that when you add the two equations, the y terms will cancel out.

For example, if the equation you want to eliminate y from is 2x + 3y = 7, and the other equation is 4x + 5y = 9, you would multiply the first equation by -5 and the second equation by 3 to obtain:

-5(2x + 3y) = -5(7) (equation 1 multiplied by -5)

3(4x + 5y) = 3(9) (equation 2 multiplied by 3)

This will result in:

-10x - 15y = -35 (equation 1 after multiplication)

12x + 15y = 27 (equation 2 after multiplication)

Now, when you add the two equations, the y terms will cancel out, and you can solve for the remaining variable x.

First, divide the spheres into three groups of three, three, and two spheres each. Weigh the two smaller groups against each other on the balance. If they balance, then the false sphere must be in the larger group of three.

Next, take any two spheres from the larger group and weigh them against two spheres from one of the smaller groups. If they balance, then the false sphere must be the remaining sphere in the larger group. If they don't balance, then the false sphere must be one of the spheres being weighed.

Finally, take the two spheres that didn't balance and weigh them against each other. Whichever one is lighter is the false sphere.

it will be 26 cm as diagonals bisect each other

Answer:

The answer is Multiplication.

Step-by-step explanation:

The coefficient of the x term in f(x) is 2, and the coefficient of the x term in g(x) is 2. When we add or subtract the two functions, the coefficient of the x term remains 2. However, when we multiply the two functions, the coefficient of the x term becomes 4. Therefore, multiplication results in the largest coefficient on the x term.

Here is the solution for each of the operations:

Addition: f(x) + g(x) = (2x −1) + (2x + 4) = 4x + 3

Subtraction: f(x) - g(x) = (2x −1) - (2x + 4) = -5

Multiplication: f(x) * g(x) = (2x −1) * (2x + 4) = 4x^2 + 6x - 4

As you can see, the coefficient of the x term in f(x) * g(x) is 4, which is larger than the coefficients of the x terms in f(x) + g(x) and f(x) - g(x). Therefore, multiplication results in the largest coefficient on the x term.

If the cost of one paperback book is less than $1, he would receive even more change.

To solve this problem, we need to know the cost of one paperback book. Unfortunately, that information is missing from the question. Without it, we cannot determine the total cost of the 5 paperback books and therefore cannot calculate Prakash's change.

However, we can make an educated guess based on the fact that the question mentions both paperback and hardcover books. Typically, hardcover books are more expensive than paperbacks, so we can assume that the cost of one paperback book is less than the cost of one hardcover book.

Assuming that each hardcover book costs $10, the total cost of 3 hardcover books would be $30. If Prakash gives the clerk $20 bills, he would pay $60 in total. If we subtract the cost of the 3 hardcover books ($30) from the total amount paid ($60), we are left with $30.

In this problem, we have two circles with different radii and central angles defining arcs with specific lengths. We are asked to compare the measures of the two central angles.

Recall that the length of an arc (arc length) can be calculated using the formula: Arc Length = Radius × Central Angle (in radians). To compare the measures of the central angles, we'll first rearrange the formula to solve for the central angle: Central Angle = Arc Length / Radius.
For the first circle with radius 16 units and an arc length, let's denote the central angle as θ₁. Thus, θ₁ = Arc Length₁ / 16.
For the second circle with radius 5 units and an arc length, let's denote the central angle as θ₂. Therefore, θ₂ = Arc Length₂ / 5.
To compare the central angles θ₁ and θ₂, we can use the ratios of the respective arc lengths and radii. If the ratio of Arc Length₁ to Arc Length₂ is the same as the ratio of 16 to 5, then the central angles are equal. If the ratio is greater, then θ₁ is greater than θ₂, and if the ratio is smaller, then θ₁ is smaller than θ₂.
Without the specific arc lengths, we cannot determine the exact relationship between the central angles, but this method can be used to compare them once the arc lengths are provided.
