A room has a length of 7 m.
A scale diagram is drawn of the room.
In the diagram, the room has a length of 1 cm.
What is the scale of the diagram?
Give your answer as a ratio in the form 1 : k, where k is an integer.
Answer:
Step-by-step explanation:
A ratio is used in scale drawings of maps and buildings.
That is:
The scale of a drawing = Drawing Length : Actual Length
A scale is usually expressed in one of two ways:
-using units as in 1 cm to 1 km
-without explicitly mentioning units as in 1 : 100,000.
A scale of 1 : 100,000 means that the real distance is 100,000 times the length of 1 unit on the map or drawing.
In your case, where the room has a length of 7m and 1cm on the diagram:
1 cm to 7m = 1cm : 7m
= 1cm : 700cm
= 1 : 700
Find the distance between (4, -1) and (-2, -1). Round answer to the nearest tenth. *
Answer:
6
Step-by-step explanation:
You substitute the points into the distance formula. There aren't decimals in this answer, so I don't think you need to round to the nearest tenth. You can also check by plotting these points down on a graph.
(4, -1) (-2, -1)
The y coordinates are the same, you just need to count from -2 to 4. There are 2 steps before 0 and 4 steps after 0. So 2 + 4 is 6.
===========================================
Work Shown:
[tex]\text{Distance Formula}\\\\d = \sqrt{(x_1-x_2)^2 + (y_1-y_2)^2}\\\\d = \sqrt{(4-(-2))^2 + (-1-(-1))^2}\\\\d = \sqrt{(4+2)^2 + (-1+1)^2}\\\\d = \sqrt{(6)^2 + (0)^2}\\\\d = \sqrt{36}\\\\d = 6\\\\[/tex]
This value is exact. No rounding is needed.
-------------
A shortcut is to subtract the x coordinates and apply absolute value
So either |x1-x2| = |4-(-2)| = |4+2| = |6| = 6
Or |x2-x1| = |-2-4| = |-6| = 6
This shortcut only works because the y coordinates the same for both points.
On a graph, you can plot the two points and count the spaces between them. You should count out 6 spaces.

Conjecture: Twice the number of units in the length of any side of a rectangle is equal to the number of square units in the area of the rectangle.
The area of ABDE is 4 and 2 X AB = 4
The area of ABCF is 2 and 2 x BC = 2.
The area of ABCF is 2 and 2 x AB = 4
The area of ABDE is 4 and 2 x BD = 4
The statement proves that the conjecture is
Answer:
The area of ABCF is 2 and 2 × AB = 4
The statement proves that the conjecture is false
Step-by-step explanation:
A conjecture is a proposition or conclusion that is presumed to be true or correct but which is based on incomplete details or information
Given the length of the sides of rectangle ABDE, we have;
Length AB = 2 units
Length DE = 2 units
The area of ABDE = 2 × 2 = 4 unit²
Therefore, the area of the rectangle ABDE is equal to 2 × the length of either AB or DE
However, the are of rectangle ABCF = 2 × 1 = 2 unit²
While the area of rectangle 2 × the length of side AB = 2 × 2 = 4 unit², which is not equal to the number of square units in the area of the rectangle.
Therefore;
The area of ABCF is 2 and 2 × AB = 4
The statement (above) proves that the conjecture is false.

a rectangle is 3x feet long and 4feet wide.the value of the perimeter (in feet) is equal to the value of the area in square feet. find x
Answer:
x = [tex]\frac{4}{3}[/tex]
Step-by-step explanation:
Rectangle:
Length = 3x feet
Width = 4 feet
Perimeter = 2*(length +width)
= 2* (3x + 4)
= 2*3x + 2*4
= 6x + 8
Area = length * width
= 3x * 4
= 12x
Area of rectangle = perimeter of rectangle
12x = 6x + 8 {Subtract 6x form both sides}
12x - 6x = 8
6x = 8 {Divide both sides by 6}
x = 8/6
x = [tex]\frac{4}{3}[/tex] feet
Answer:
3 feet x 4 feet= 12 feet

Solve the inequality. −2≤x−11≤6
Answer:
9≤x≤17
Step-by-step explanation:
In order to solve this equation, you need to just add 11 to each side
-2≤x-11≤6
to
9≤x≤17
The reason that 11 was added to this equation was that we were trying to isolate x, and it goes without saying that (x-11)+11 is x . 11 was added to the other sides because it is an inequality and that will keep it balanced.
The value of the variable 'x' will be more than or equal to 9 and less than or equal to 17.
What is inequality?Inequality is defined as an equation that does not contain an equal sign. Inequality is a term that describes a statement's relative size and can be used to compare these two claims.
The inequality is given below.
−2 ≤ x − 11 ≤ 6
Add 11 on each side of the inequality. Then we have
−2 + 11 ≤ x − 11 + 11 ≤ 6 + 11
9 ≤ x ≤ 17
The value of the variable 'x' will be more than or equal to 9 and less than or equal to 17.

Jaycie has 21 gallons of gas in her car and uses approximately .05 gallons of gas each mile that she drives. Which equation shows the linear relationship between x, the number of miles Jaycie has driven, and y, the total gallons of gas in her car? a. Y = 21x - .05 b. Y = -.05(x+21) c. Y = 21 - .05x d. Y =21 + .05x
Given:
Jaycie has 21 gallons of gas in her car and uses approximately .05 gallons of gas each mile that she drives.
To find:
The equation which shows the linear relationship between x, the number of miles Jaycie has driven, and y, the total gallons of gas in her car.
Solution:
We have,
Initial amount of gas in car = 21 gallons
So, y-intercept of the linear relationship is 21.
It uses approximately .05 gallons of gas each mile that she drives.
It means, the gas is decreased by .05 gallons for each mile.
So, slope of the linear relationship is -0.05. Here, negative sign represents the decrease in amount of gas.
Slope intercept form of a line is
[tex]y=mx+b[/tex]
where, m is slope and b is y-intercept or initial value.
Substitute m=-.05 and b=21 in the above equation.
[tex]y=-.05x+21[/tex]
[tex]y=21-.05x[/tex]
So, the equation [tex]y=21-.05x[/tex] represents the linear relationship between x, the number of miles Jaycie has driven, and y, the total gallons of gas in her car.
Therefore, the correct option is c.
