[tex]Scale= 1 : 2000[/tex]

Required

Fill in the table

The scale implies that:

To fill in the gaps of actual measurements, we simply multiply the scale measurement by 2000

To fill in the gaps of scalar measurements, we simply divide the actual measurement by 2000

For the flag height, we have:

[tex]Scale\ Measurement = 13.2\ cm[/tex]

Using the analysis above:

[tex]Actual = 2000 * 13.2\ cm[/tex]

[tex]Actual = 26400\ cm[/tex]

Convert to meters

[tex]Actual = 26400m/100[/tex]

[tex]Actual = 264m[/tex]

For the flag length, we have:

[tex]Actual\ Measurement = 396\ m[/tex]

Using the analysis above:

[tex]Scale\ Measurement = 396\ m /2000[/tex]

[tex]Scale\ Measurement = 0.198\ m[/tex]

Convert to centimeters

[tex]Scale\ Measurement = 0.198\ cm * 100[/tex]

[tex]Scale\ Measurement = 19.8\ cm[/tex]

For the height of crescent moon, we have:

[tex]Actual\ Measurement = 99\ m[/tex]

Using the analysis above:

[tex]Scale\ Measurement = 99\ m /2000[/tex]

[tex]Scale\ Measurement = 0.0495\ m[/tex]

Convert to centimeters

[tex]Scale\ Measurement = 0.0495\ cm * 100[/tex]

[tex]Scale\ Measurement = 4.95\ cm[/tex]

First convert [tex]\frac{1}{5}[/tex] to a decimal : 0.2

y represents how many strawberries Zoe ate

x represents how many strawberries Nora ate

If you take the equation- y = 0.2x and plug how many strawberries Nora ate you would claculate how many Zoe ate.

       For example: say Nora ate 10 strawberries the equation would be- y(how many strawberries Zoe ate) = 0.2 · 10 ( the naumber of strawberries Nora ate)

Answer:

[tex]L + W \leq 9[/tex]

Step-by-step explanation:

Given

Represent lifeguarding cars with L

Represent washing cars with W

[tex]Hours = 9\ hours[/tex] --- at most

Required

Express the scenario as an inequality

First, we need to determine the number of hours Lauren can work.

This is calculated as follows:

[tex]Total\ Hours = L + W[/tex]

From the question, we understand that the total hours cannot exceed 9 hours.

This can be expressed as [tex]\leq 9[/tex]

So, we have:

[tex]Total\ Hours \leq 9[/tex]

Substitute L + W for Total Hours

[tex]L + W \leq 9[/tex]

Answer:he should build them 25x10

Step-by-step explanation:

Encik Ahmad can build 10 square plots with three different sizes.

Rectangle is a polygon in two dimensional geometry which has four sides and four angles and each angle being right angles.

Length of the rectangular plot = 85 m

Width of the rectangular plot = 30 m

We have to find the number of square plots Encik Ahmad can built of three different sizes.

For that first we take a 45 m length of the plot.

Divide it to three equal lengths. We get three lengths with each 15 m length.

Along the width also, divide into two equal width, each having a width of 15 m.

Each 15 m length, we will get two square plots.

Along 45 m length, we get 3 × 2 = 6 square plots.

The remaining rectangle has length 40 m and width 30 m.

Divide this length as 30 m and 10 m.

So we get a square of dimension 30 m.

Remaining is a rectangle whose remaining length is 10 m and width 30 m.

Along the width, divide into three equal widths, each 10 m.

So there we get three square plots with side length 10 m.

So we have 10 square plots, 6 having the side length 15m, 1 having the side length 30 m and 3 having the side length 10 m.

Hence he get 10 square plots having three different sizes as 15 m, 30 m and 10 m.

Answer:

15 + 3.75x = Y

Step-by-step explanation:

Answer:

The graph shows a line of best fit because the points are plotted evenly above and below the line.

Step-by-step explanation:

The best explanation is that the graph shows a line of best fit because the points are plotted evenly above and below the line option (D) is correct.

A mathematical notion called the line of the best fit connects points spread throughout a graph. It's a type of linear regression that uses scatter data to figure out the best way to define the dots' relationship.

[tex]\rm m = \dfrac{n\sum xy-\sum x \sum y}{n\sum x^2 - (\sum x)^2} \\\\\\\\rm c = \dfrac{\sum y -m \sum x}{n}[/tex]

We have a line of best fit shown in the picture.

As we know if the slope of the line is positive then the correlation will be positive.

From the line of best fit:

Because the points are evenly spaced above and below the line, the graph displays a line of best fit.

Thus, the best explanation is that the graph shows a line of best fit because the points are plotted evenly above and below the line option (D) is correct.

Answer:

y = - [tex]\frac{3}{4}[/tex] x + 3

Step-by-step explanation:

Assuming you require the equation of the line

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Here m = - [tex]\frac{3}{4}[/tex] , thus

y = - [tex]\frac{3}{4}[/tex] x + c ← is the partial equation

To find c substitute (- 4, 6) into the partial equation

6 = 3 + c ⇒ c = 6 - 3 = 3

y = - [tex]\frac{3}{4}[/tex] x + 3 ← equation of line

The equation of a line with given coordinate point and slope is y = -3/4 x + 3.

The given coordinate point is (-4, 6) and slope (m) = -3/4.

The slope of the line is the ratio of the rise to the run, or rise divided by the run. It describes the steepness of line in the coordinate plane.

Put, (x, y) = (-4, 6) and m=-3/4 in y=mx+c, we get

6 = -3/4 (-4) + c

⇒ 6 = 3 + c

⇒ c = 3

Substitute m=-3/4 and c=3 in y=mx+c, we get

y = -3/4 x + 3

Therefore, the equation of a line with given coordinate point and slope is y = -3/4 x + 3.

Answer:

6,37

Step-by-step explanation:

Dado que la energía de la bomba atómica = 8,9 x 10 ^ 13 Joules

se nos dio que la magnitud del terremoto M viene dada por

M = 0,667 ∙ log⁡ (E / 〖10〗 ^ 4,4)

Sustituyendo valores en consecuencia;

 M = 0,667 ∙ log⁡ (8,9 x 10 ^ 13 Julios / 1 * 10 ^ 4,4)

 M = 0,667 ∙ log⁡ (8,9 x 10 ^ 8,6)
