Scale Question Rush Rush !!!!!!!!!!!!!!! Extra points for details!!

The distance between the two places is 420 kilometers, and how many centimeters should be drawn on a map with a scale of 1:3000000?

420 km 42000000 cm.

should be drawn. 42000000 1 3000000 cm) 2On the scale is 1:

The distance from city A to city B is measured on the map of 2,000,000 centimeters, and a car can drive from city A to city B at a speed of 60 kilometers per hour.

The actual distance between the two cities is.

cm) 150 (km).

Arrive at the need. 150 60 hours).

3.The length of a part drawn on the drawing is 8 cm, and its actual length is 2 mm, what is the scale of this drawing?

Scale Distance on Graph: Actual distance.

8 cm: 2 mm.

80 mm: 2 mm.

Hello! The correct answers are cm in that order

2. The distance between A and B can be obtained, s=150km, t=s v=hours.

3. The scale is: 2:80=1:40

Hope mine helps you! Thank you!!

1 1 m = 100 cm 14 cm should be drawn in proportion.

2 hours.

Proportions, different sizes, different dissemblement:: 6 Length: 51 cm, Width: 34 cm.

3 Length: 48 cm, Width: 36 cm.

Calculation method:Take 9:6, for example.

24 inches (in) = centimeters (cm) 61 (cm).

9x）²+6x）²=61。

x=。9x=51。

6x=34。

DisplaycompositionSection:

1. LCD module.

Glass substrate: Inside are liquid crystals and grid-like printed circuits. Timing control:

It is used to generate the timing and voltage required to control the deflection of liquid crystal molecules. Lamp: Produces a white light source.

Backlight: Reflects the light generated by the lamp onto the LCD screen.

2. Wheel royal finch control wax early board.

The control board plays the role of signal conversion. Converts signals from various input formats into signals with fixed output formats. For example, the input signal to the screen of 1024 x768 can be 768, etc., and finally converted into the output format 1024 768.

3. Inverter.

High pressure is generated and used to light the tube.

1.In the case of the same width, the larger the scale of the map, the smaller the representation range, and the more detailed the representation. Conversely, the smaller the scale of the map, the larger the scale range, and the more brief the content is represented

2.Name a few common types of maps: teaching maps, topographic maps, aeronautical charts, astronomical maps.

3.On the contour topographic map, where the contour line is sparse, it means that the terrain is flat and open; Where the contour lines are dense, it means that the terrain is dense and undulating

1.In the case of the same size, the larger the map scale, the smaller the representation range and the less content is represented such as 1:5000; Conversely, the smaller the scale of the map, the larger the scale and the more content it represents, such as 1::

100 thousand. 2.List a few common types of maps: administrative maps, mineral distribution maps, population density distribution maps, and three-dimensional maps (3D stereoscopic maps, such as sand tables, model stereoscopic maps, three-dimensional maps made by computer software).

3.On the contour topographic map, where the contour lines are sparse, it indicates that the terrain is gently undulating and the drop gradient is small Where the contour lines are dense, it means that the terrain is undulating with large drops, large gradients, and steep slopes

Map classification is to classify certain characteristics of maps into certain categories. The method of classification is usually divided according to its scale, content, use, scope of cartographic area and form of use.

Maps are divided into large-scale maps (scales greater than 1:10,000), medium-scale maps (scales between 1:10,000 and 1:1,000,000), and small-scale maps (scales less than 1:1,000,000).

Maps are divided into general maps and thematic maps according to their contents. Normal map.

It is a kind of general map, which comprehensively depicts the physical geography and general socio-economic characteristics of a region. The contents of the representation include: water system, residential land, road network, landform, soil, vegetation, boundary line, economic phenomena, cultural signs, etc.

Ordinary maps are further divided into topographic maps and overview maps. Topographic map, whose scale is greater than 1:1 million, its outstanding features:

Detailed and accurate, the projection distortion is small, and it can be measured on the map. It is an important topographical data for the country's economic construction, national defense construction, and military operations and training. This kind of diagram is generally measured or based on a measured map.

Thematic maps. Also known as "special map" or "subject map", it is a map that uses an ordinary map as the base map, focusing on a certain or several elements, and is suitable for the special needs of a certain professional department. Thematic maps are usually divided into:

Natural maps, population maps, economic maps, political maps, cultural maps, historical maps, etc.

According to its use, maps are divided into: reference maps, teaching maps, topographic maps, aeronautical charts, nautical charts, coastal maps, astronomical maps, traffic maps, tourist maps, etc.

Maps are divided into world maps, hemisphere maps, continent maps, ocean maps, sea maps, country (regional) maps, province maps, city and county maps, etc.

According to the form of use, maps are divided into: wall charts, desktop maps, atlases (books), etc.

In addition, maps can also be divided into micromaps, digital maps, electronic maps, image maps, etc. according to their form of expression.

The actual length is: 20 1 400 8000 (cm) 80 (m).

The actual width is: cm) 34 (m).

Actual land area: 80 34 2720 (sq.m.).

10.The centimeters on a part diagram represent the actual distance in meters, and the scale of this diagram is ( ).

11.The scale of a map is 1 200,000, the distance from A to B is known to be 5,000 meters, and the distance between A and B on the map is ( ).

12.The scale of a floor plan is 1 2000, the distance on the map is 4 cm, and the actual distance is ( ) meters.

13.A 4 cm line segment on a floor plan represents 200 meters. The scale of this floor plan is ( ).

14.On a drawing, the longest part of the measurement is centimeters, and the actual longest part of this part is 24 centimeters. The scale of this figure is ( ).

15.The distance from the school to Nanhu is 1,800 meters, and this distance is represented by 4 decimeters on a floor plan, and the scale of this plan is ( ).

16.On a map with a scale of 1:500,000, the distance from city A to city B is measured in centimeters, and the actual distance from city A to city B is ( ).

All converted to the same unit of centimeters, and then according to the distance on the algorithm diagram, the actual distance == scale.

The distance on the map is x centimeters.

1:90000=x：450000

The x=5 method goes like this: you do the math again.

1km=100000mm

With the actual distance * scale.

For example, if the numerical scale is 1:5000000, it means that 1cm on the figure is equal to the actual 5000000cm

The Hound runs two steps away the rabbit runs three steps--- the Hound runs 1 2 per step, the rabbit runs 1 3 per step The Hound runs three steps, the rabbit can run four steps--- in the same time the Hound runs 3 * 1 2 = 3 2, the rabbit runs 4 * 1 3 = 4 3

Hound speed: rabbit speed = 3 2 : 4 3 = 9: 810 (9-8) 9 = 90 meters.
