A 15-lb mixture, she should use 1.256 pounds of dried-fruit mixture and 13.744 pounds of nuts.

Based on the given information, we can set up the following system of equations:
Equation 1: x + y = 15 (since the total weight of the mixture is 15 pounds)
Equation 2: (5.90 * x) + (14.75 * y) = 9.44 * 15 (since the total cost of the mixture is the cost per pound multiplied by the weight of each component)
Now, let's convert this system of equations into matrix form:
| 1  1 |   | x |   | 15 |
| 5.90  14.75 |   | y | = | 9.44 * 15 |
To solve for x and y, we can use matrix algebra. We can multiply the inverse of the coefficient matrix by the right-hand side matrix to get the solution matrix:
| x |   | 1  1 |^-1   | 15 |
| y | = | 5.90  14.75 |      | 9.44 * 15 |
Using matrix calculations, we find that the inverse of the coefficient matrix is:
| 0.0877  -0.0576 |
| -0.0059   0.0678 |
Now, multiplying the inverse matrix by the right-hand side matrix gives us:
| x |   | 0.0877  -0.0576 |   | 15 |
| y | = | -0.0059   0.0678 | * | 9.44 * 15 |
Simplifying the multiplication gives us:
x = 1.256
y = 13.744
Therefore, the saleswoman should use 1.256 pounds of dried-fruit mixture and 13.744 pounds of nuts to get a 15-pound mixture.

When we evaluate the given expression, A/5 + √(B - C), the result obtained is 9 (option B)

First, we shall determine the value of A. Details below:

Quadratic equation is expressed as:

x² - (sum of root)x + product of root

Comparing the above with x² - 11x + 30, we have

x² - 11x + 30 = x² - (sumof root)x + product of root

Product of roots = 30

Thus,

A = 30

Next, we shall determine the value of B. details below:

f(x) = x² + 5

f(2) = 2² + 5

f(2) = 9

Thus,

B = 9

Next, we shall determine the value of C. Details below:

Let

x + 4 = 0

Thus,

x = -4

Substitute the value of x into x² - 2x - 24 to obtain the remainder as shown below:

Remainder = x² - 2x - 24

Remainder = (-4)² - 2(-4) - 24

Remainder = 0

Thus,

C = 0

Finally, we shall determine value of A/5 + √(B - C). Details below:

A/5 + √(B - C) = 30/5 + √(9 - 0)

A/5 + √(B - C) = 6 + √(9

A/5 + √(B - C) = 6 + 3

A/5 + √(B - C) = 9

Thus, the value of A/5 + √(B - C) is 9 (option B)

No, this shape does not belong in a group of shapes that have more than one pair of perpendicular sides.

In order to determine if the shape belongs to a group of shapes with more than one pair of perpendicular sides, we need to examine the number of right angles in the shape.

A right angle is a 90-degree angle, and shapes with perpendicular sides have right angles at their intersections. By counting the number of right angles in the shape, we can determine if it has more than one pair of perpendicular sides.

If the shape has only one right angle, then it does not have more than one pair of perpendicular sides. But if it has two or more right angles, then it would belong to the group of shapes that have more than one pair of perpendicular sides.

Given:

\(\Delta ABC\sim \Delta D E F\)

\(AB=18,BC=21,AC=24,EF=7\)

To find:

The scale factor of \(\Delta ABC\) to \(\Delta D EF\).

Solution:

We have,

\(\Delta ABC\sim \Delta D EF\)

So, side BC is the corresponding side of EF.

Now, scale factor of \(\Delta ABC\) to \(\Delta D EF\) is

\(\text{Scale factor}=\dfrac{\text{ Side of }\Delta D EF}{\text{Corresponding side of }\Delta ABC}\)

\(\text{Scale factor}=\dfrac{EF}{BC}\)

\(\text{Scale factor}=\dfrac{7}{21}\)

\(\text{Scale factor}=\dfrac{1}{3}\)

Therefore, the scale factor of \(\Delta ABC\) to \(\Delta D EF\) is \(\dfrac{1}{3}\).  

In the given rectangle,

The value of x is 3

The value of NP is 18

From the question, we are to determine the value of x in the given diagram.

The diagram shows a rectangle with its diagonals.

Since the diagonals of a rectangle bisect each other, we can write that

2x + 3 = 12 - x

Solve the equation for x

2x + 3 = 12 - x

Add x to both sides of the equation

2x + x + 3 = 12 - x + x

3x + 3 = 12

Subtract 3 from both sides of the equation

3x + 3 - 3 = 12 - 3

3x = 9

Divide both sides of the equation of by 3

3x / 3 = 9 / 3

x = 3

Thus,

The value of x is 3

To determine the value of NP

NP = 2(12 - x)

Substitute the value of x

NP = 2(12 - 3)

NP = 2(9)

NP = 18

Hence, the value of NP is 18

Answer:

Even set = {HTT, THT, TTH, TTT}

Step-by-step explanation:

We are given that three coins are tossed; the result is at most one head.

And we have to find the sets of elements that are included in the sample space.

Firstly, as we know that when three coins are tossed, the total number of cases formed is 8.

Let Head on the coin be represented by 'H' and the Tail on the coin be represented by 'T'.

So, the sample space so formed is;

S = {HHH, HTH, HHT, THH, THT, TTH, HTT, TTT}

Now, our event is at most one head. So, the sample space for the favorable event is given by;

Even set = {HTT, THT, TTH, TTT}

In this, three cases are of head occurring only once and one case is of head not appearing in three tosses of a coin.

The coordinate of the triangle after the translation is given by A' ( 0 , -3 ) with 4 units right and 4 units down

A translation moves a shape up, down, or from side to side, but it has no effect on its appearance. A transformation is an example of translation. A transformation is a method of changing a shape's size or position. Every point in the shape is translated in the same direction by the same amount.

Given data ,

Let the coordinate of the triangle be represented as A

Now , the coordinate A = A ( -4 , 1 )

Now , the coordinate of the triangle after translation is A' ( 0 , -3 )

when there is a translation of the coordinate A by 4 units to the right , we get

A to 4 units right = A ( -4 + 4 , 1 )

The new coordinate of A = A ( 0 ,  1 )

Now , A to 4 units down , we get

The coordinate of A' = A' ( 0 , 1 - 4 )

The coordinate of A' = A' ( 0 , -3 )

Hence , the translated coordinate is A' ( 0 , -3 )

Answer:

Given the information you provided, we can model cellular phone usage over time with an exponential growth model. An exponential growth model follows the equation:

`y = a * b^(x - h) + k`

where:

- `y` is the quantity you're interested in (cell phone usage),

- `a` is the initial quantity (34 million in 1995),

- `b` is the growth factor (1.22, representing 22% growth per year),

- `x` is the time (the year),

- `h` is the time at which the initial quantity `a` is given (1995), and

- `k` is the vertical shift of the graph (0 in this case, as we're assuming growth starts from the initial quantity).

So, our specific model becomes:

`y = 34 * 1.22^(x - 1995)`

To find the cellular usage in 2003, we plug 2003 in for x:

`y = 34 * 1.22^(2003 - 1995)`

Calculating this out will give us the cellular usage in 2003.

Let's calculate this:

`y = 34 * 1.22^(2003 - 1995)`

So,

`y = 34 * 1.22^8`

Calculating the above expression gives us:

`y ≈ 97.97` million.

So, the cellular phone usage in 2003, according to this model, is approximately 98 million.

The image that results from the dilation transformation is as shown in the attached file with coordinates as:

G'(0, -8)

H'(8, 0)

I'(-8, 4)

A dilation is defined as a transformation that produces an image that is the same shape as the original, but is a different size.

The coordinates of the given triangle are:

G(0, -2)

H(2, 0)

I(-2, 1)

Now, when an object with coordinates is dilated by a factor about the origin, what we will do is to multiply each coordinate by that factor . The factor of dilation is 4 and as such we have:

G(0, -2) * 4 = G'(0, -8)

H(2, 0) * 4 = H'(8, 0)

Answer:

n = 4

Step-by-step explanation:

Let's put all of our variables on one side, and all of our non-variable numbers on the other. (I like to do this so that the variable isn't negative. You'll still get the same answer.)

So we can minus 2n on both sides, giving us 7 = n + 3.

Then, let's do our non-variables and subtract 3 from each side. This gives us 4 = n or n = 4.

Therefore, n = 4.

Answer:

17.32 meters

Step-by-step explanation:

Let’s call the height of the tower H. The distance from the point to the base of the tower is 10 m. The angle of elevation from the point to the top of the tower is 60 degrees.

Using trigonometry, we can calculate that:

tan (60) = H / 10

H = 10 * tan (60)

H = 10 * √3

H = 17.32 m

Therefore, the height of the tower is 17.32 meters.

Answer:

The mean distance to his friends' house is between 2 -3 blocks.

Step-by-step explanation:

1. Mean = Average.

Average = (n1+n2+n3....nx)/x

2. The average = 1+2+5+3+2+2+5+3/8

3. Therefore, the answer is 2.875, making the mean between 2 and 3

Answer:

The statement that supports the data is the mean distance to his friends' houses is in between 2 and 3 blocks.

Step-by-step explanation:

What is mean, median and mode?

Mean: The average of the given data points.

Median: The central point of the whole data set.

Mode: The number that occurs for the maximum times in the data set.

Given:

Karl records the number of city blocks from his house to each of his friends houses.

Data set for the number of city blocks to eight friends houses:

{1, 2, 5, 3, 2, 2, 5, 3}

The first option: it is given that the maximum number of blocks the Karl lives from his friend is 4, but according to the data set, the maximum number of house blocks should be 5.

Hence, this option is incorrect.

The second option: It is given that the mode shows that Karl has 3 friends who live 3 blocks from him, but according to the given data set Karl has 3 friends who lives 2 blocks from him. Hence the mode is 2.

Hence, this option is incorrect.

The third option: It is given that the minimum distance from Karl's house to a friend's is 2 blocks, but according to the given data set the minimum distance from Karl's house to a friend's is 1 block.

Hence, this option is incorrect.

The fourth option:  It is given that the mean distance to his friend's houses is in between 2 and 3 blocks.

We will find the mean for the given data set.

⇒ Mean = (Sum of all the data points) / (Total number of data points)

⇒ Mean = (1 + 2 + 5 + 3 + 2 + 2 + 5 + 3)/8

⇒ Mean = 23/8

⇒ Mean = 2.875

∴ The mean distance from Karl to his friend's houses is 2.875 which is in between 2 and 3.

Hence, this option is correct.

Therefore, the fourth option which says the mean distance between Karl and his friend's houses is in between 2 and 3 is correct.

the height of the flag pole is approximately 57.18 meters.

How to find?

We can see that triangle ABC and triangle ACD are right triangles.

Let's first find the height of the building BC using the right triangle ABC:

tan 30° = BC/40

BC = 40 tan 30°

BC = 20√3

BC ≈ 34.64 m

Now, we can find the height of the flag pole CD using the right triangle ACD:

tan 65° = CD/BC

CD = BC tan 65°

CD = (20√3) tan 65°

CD ≈ 56.18 m

Finally, we can find the total height of the flag pole by adding the height of the man (1 m):

total height = CD + 1

total height ≈ 57.18 m

Therefore, the height of the flag pole is approximately 57.18 meters.
