The amount of money that Charlie saves each week is directly proportional to the amount he earns. Last week Charlie saved $32 on his earnings of $512. At the same rate, how much will Charlie save this week on his earnings of $448?

The correct scenario is B) She picked nine flowers from each of 3 flower beds.

The question posed asks which scenario accurately describes the mathematical expression 9×3 in the context of picking flowers.  The expression 9×3 implies that the number 9 (the number of flowers picked from one bed) is multiplied by 3 (the total number of beds from which flowers are picked), thus resulting in a total count of flowers picked. Therefore, the multiplication of these two numbers indicates repeated addition, such as picking a set number of flowers from multiple identical sets.

Additionally, if we were to consider other aspects such as flower color ratios or Darwinian genetics, we could take example scenarios such as: "50% of the flowers are blue and 50% of the flowers are red" or "You would expect 300 homozygous dominant blue flowers, 300 heterozygous blue flowers, and 200 homozygous recessive red flowers", but these do not pertain directly to the mathematical operation represented by 9×3 in this context.

Answer:

The frequency of the wave is 109.52 Hz.

Step-by-step explanation:

Given : A wave traveling at 230 m/sec has a wavelength of 2.1 meters.

To find : What is the frequency of the wave?

Solution :

We know that,

[tex]\text{Velocity} =\text{ Wavelength}\times \text{Frequency}[/tex]

We have given,

Velocity of wave is 230 m/s.

Wavelength is 2.1 meters.

Substitute in formula,

[tex]230 =2.1\times \text{Frequency}[/tex]

[tex]\text{Frequency}=\frac{230}{2.1}[/tex]

[tex]\text{Frequency}=109.52[/tex]

Therefore, The frequency of the wave is 109.52 Hz.

The 7 in .6667 when Kyle divided 2 3 came from rounding the decimal during the calculation process in the calculator.

The 7 in .6667, when Kyle divided 2 3 on his calculator, came from rounding the decimal.

When a calculator displays a decimal, it often rounds the number to a specific decimal place, causing the appearance of non-repeating numbers like 7 in this case.

Limited by the display's capacity for decimal places, calculators round off the result, leading to the appearance of additional digits beyond the actual result.

The vertical height of the blimp above the ground, which is seen by Jay and Libby while working outside, is 7027 ft.

In a right angle triangle, the ratio of the opposite side to the adjacent side is equal the tangent angle between the adjacent side and hypotenuse side.

[tex]\tan\theta=\dfrac{b}{a}[/tex]

Here, (a) is the adjacent side, (b) is the opposite side.

Let the height of the blimp from the ground is y ft and the length of the ground to the Libby's position is x ft shown in the attached image below.

As the angle made by the Libby at the height of the blimp is 43 degrees. Therefore,

[tex]\tan43=\dfrac{y}{x}\\x=1.0724y[/tex]          ......1

Here, Jay is mowing the lawn approximately 2,500 feet (ft) from Libby when they both see the blimp.

Libby looks up from her gardening at an angle of while Jay looks up at an angle of 35 degrees. Therefore,

[tex]\tan35=\dfrac{y}{x+2500}[/tex]

Put the value of x in the above equation from equation one as,

[tex]\tan35=\dfrac{y}{1.0724y+2500}\\0.7002(1.0724y+2500))=y \\y\approx7027 \rm \; ft[/tex]

Hence, the vertical height of the blimp above the ground, which is seen by Jay and Libby while working outside, is 7027 ft.

Answer:

B) 20/4

Step-by-step explanation:

Required rate = [tex]\frac{Number of balls launched}{Time}[/tex]

From the graph, it is evident that (4, 20), (8, 40), (12, 60) and (16, 80) are points.

This means that

20 balls launched in 4 seconds and the rate = 20/4

40 balls launched in 8 seconds and the rate = 40/8 = 20/4

60 balls launched in 12 seconds and the rate = 60/12 = 20/4

80 balls launched in 16 seconds and the rate = 80/16 = 20/4

Hence, the rate per second at which the machine launches the balls is 20/4 and the correct option is (B).

To determine which transformation created triangle q'r's' from triangle QRS, one would compare the vertices of the original and translated triangles. This comparison would reveal the horizontal and vertical distances each point has been moved, indicating the correct translation.

The question asks which transformation created triangle q'r's' from triangle QRS. The correct answer will be the translation that moves triangle QRS to the new position of triangle q'r's'. When a figure is translated, all points move the same distance in the same direction. Given the options, we need to choose the translation that shifts the triangle in the correct direction and by the correct number of units.

Without specific coordinates, we cannot determine the exact translation from the given options. However, if we had the positions of triangles QRS and q'r's', we could compare their corresponding vertices to find the difference in their 'x' (horizontal) and 'y' (vertical) coordinates. This difference would tell us how far and in which direction the triangle has been translated.

The difference between the mean times is about 16 times the mean absolute deviation of the data sets.

We are given the mean and mean absolute deviation of two teams in a table as:

                                              Team A           Team B

             Mean                        127.9 s             127.4 s

Mean Absolute Deviation     0.26 s             0.23 s

The difference of mean between two team is: 0.5 s

( Since 127.9-127.4=0.5 s)

Also, the difference of Mean absolute deviation is: 0.03 s

( Since, 0.26-0.23=0.03 s)

Now let the difference of the mean times be equal t n times the difference  of the mean absolute deviation of two teams

i.e.

      0.5=n×0.03

⇒ n=0.5/0.03

⇒ n=16.6667

which is approximately equal to 16.

Hence, The difference between the mean times is about 16 times the mean absolute deviation of the data sets.
