Perimeter of a rectangle = 2l + 2w
where
l is the length
w is the width
From the question
l = 12m
w = 400 cm
First we must convert the length from meters to centimeters
1 m = 100 cm
12 m = 12 × 100 = 1200 cm
So l = 1200 cm
Substitute the values into the above formula
We have
Perimeter = 2(1200) + 2(400)
= 2400 + 800
We have the final answer as
Perimeter = 3200 cmHope this helps you

13 people fit comfortably in a 5 foot by 5 foot area. Use this value to estimate the size of a crowd that is 5 feet deep on one side of the street along a 4 mile section of a parade route.
Answer:
There are 203069 people in the crowd
Step-by-step explanation:
The first step in solving this problem is to ensure that we are working with the same units throughout the solution process. To do this, we will have to convert 4 miles to feet. (This is because every other unit is in feet).
Note: ( 1 mile =5280 feet)
4 miles = 21120 feet.
The next step is to calculate the area that the entire parade is occupying. This can be done by multiplying the length of the parade by the breadth. In this case, it will be 21120ft X 5 ft = 105600 square feet.
We can now at this point, find the area occupied by only one person.
if 13 people occupy 25 square feet (5ft X5 ft)
1 person will occupy 25/13 = 1.92 square feet
We can finally get the number of people in the crowd by multiplying the area occupied by the whole crowd by the area of one person. This will be
105600 X 1.92= 203069 people in the crowd

A rectangular flour canister has dimensions of 512 inches by 4 inches by 10 inches. A smaller sugar canister has dimensions of 312 inches by 3 inches by 8 inches. How much smaller is the volume of the sugar canister than the flour canister?
Answer:
The amount by which the sugar canister is smaller than the flour canister is 136 in³
Step-by-step explanation:
The dimensions of the flour canister = 5 and 1/2 inches by 4 inches by 10 inches
(5 and 1/2 = (5 1/2))
(3 and 1/2 = (3 1/2))
The dimensions of the smaller sugar canister = 3 and 1/2 inches by 3 inches by 8 inches
The volume of the rectangular prism = Length × Width × Height
∴ The volume of the flour canister = (5 1/2) × 4× 10 = 220 in.³
The volume of the sugar canister = (3 1/2) × 3 × 8= 84 in.³
The difference in volume between the flour canister and the sugar canister is given as follows;
220 in.³ - 84 in.³ = 136 in.³
The amount by which the sugar canister is smaller than the flour canister = 136 in.³.

Answer: -24.8 or 24 4/5
Step-by-step explanation:
How to find the mean: add up ALL the number you want or need then DIVIDE by how many there are.
So: -28 + -26 + - 13 + -39 + -18 = -124
You are not done though.
You HAVE to divide -124 by 5.
so your mean should be -24.8 degrees feriheit,
Choose the number line that correctly compares 24 and 4.256
A number line shows the comparison between numbers, at a regular interval.
The correct number line that compares [tex]\sqrt{24[/tex] and [tex]4.256[/tex] is (c)
The numbers are given as:
[tex]n_1 = \sqrt{24}[/tex]
[tex]n_2 = 4.256[/tex]
So, we have:
[tex]n_1 = \sqrt{24}[/tex]
Take square roots
[tex]n_1 = 4.899[/tex]
4.899 is greater than 4.256 i.e. [tex]n_1 > n_2[/tex]
So, we have:
[tex]\sqrt{24} > 4.256[/tex]
Number lines increases in value towards the right. This means that:
[tex]\sqrt{24}[/tex] will be at the right-hand side of 4.256[tex]\sqrt{24[/tex] will be between 4.8 and 4.9Hence, the correct number line is: (c)

Examine the table of input (x) and output (y) values below. Is there a relationship between the input and output values? If so, write an equation for this relationship.
Answer:
y = 3x -1
Step-by-step explanation:
y = mx +/- b
To find the y-intercept, using the table, we look for when x = 0. In this question, when x=0, y = -1. Therefore the y-intercept is -1.
to find the slope (m), we just plug in an "x" value and "y" value, and solve for "m".
i.e.
2 = 1m - 1
3 = 1m
m = 3 = slope
If you use this with any of the other values you will get the same result.

1. A man pushes a lawn mower with a force of 30 lb exerted at an angle of 30° to the ground. Find the
horizontal and vertical component of the force.
Answer:
3
Step-by-step explanation:
The horizontal component of the force is 25.98 lb and the vertical component is 15 lb.
What is vector?A vector quantity has both magnitude and direction. It is added using parallelogram law of addition.
The sum of two vector quantities is always a vector quantity.
The sum of two vector quantities can vary from their scalar difference to their scalar addition.
Given that,
The force applied by the man is 30 lb.
The angle the force makes with ground is 30°.
For a vector A making angle x with the horizontal axis the horizontal and vertical component are given as,
The horizontal component is ACos(x)
And, the vertical component is ASin(x)
Thus, the horizontal and vertical component of the force are
Horizontal component = 30Cos(30°)
= 30 × √3 / 2
= 25.98
Vertical component = 30Sin(30°)
= 30 × √3/2
= 15
Hence, the horizontal and vertical components of the force are 25.98 lb and 15 lb respectively.

Step-by-step explanation:
We have to assume that the question is referring to the doubly-shaded length, the one that is 10 bright blue units long.
You can read the overall length of the shaded area as 5/4, from the markings.
For the next part, you need to count the number of units that are shaded bright blue (10) and the number that are shaded blue overall (15). As a fraction of those shaded blue overall, the ones shaded bright blue are 10/15 = 2/3.
So, the length shaded bright blue is 2/3 of the overall length of 5/4. It is represented by the product ...

Ask Richard swim underwater his elevation changes and family for six minutes altogether a change in -30 feet what was the change in elevation drink each minute what was the change in elevation during each minute
Answer:
The change of elevation during each minute is -5 feet per minute
Step-by-step explanation:
Here in this question, we are interested in calculating the change in elevation during each minute given that there was a total change of -30 feet in six minutes altogether.
Now, to calculate the change in elevation during each minute, we need to assume that the change in elevation per each of the minutes is the same.
So to calculate the change in elevation during each of the six minutes, we simply divide the total change in elevation by the total number of minutes.
Mathematically, that would be -30 feet/6 minutes = -5 feet per minute

What is Proportion?
The proportion formula is used to depict if two ratios or fractions are equal. The proportion formula can be given as a: b::c : d = a/b = c/d where a and d are the extreme terms and b and c are the mean terms.
Given data ,
Let the equation be represented as A
Now , the value of A is calculated as
Let the number of thin paintbrushes in the kit be = x
The value of x = 4
Let the number of thick paintbrushes in the kit be = y
The value of y = 6
Now , the proportion is given by
The ratio of thick paintbrushes to thin paintbrushes = number of thick paintbrushes in the kit / number of thin paintbrushes in the kit
Substituting the values in the equation , we get
The ratio of thick paintbrushes to thin paintbrushes = 6 / 4
The ratio of thick paintbrushes to thin paintbrushes = 3 / 2
The ratio of thick paintbrushes to thin paintbrushes = 3 : 2
Therefore , the value of A is 3 / 2
Hence , the ratio of the paintbrushes is 3 : 2

According to Euclidean geometry, a plane contains at least points that on the same line.
Answer:
According to Euclidean geometry,a plane contains at least THREE points that DO NOT LIE on the same line.
Step-by-step explanation:
Three non-collinear points (points not on a single line). A line and a point not on that line. Two distinct but intersecting lines.
According to Euclidean geometry, a plane contains at least; 3 Points
The 3 points; do not lie on the same line
In Euclidean Geometry, a plane is defined as a flat surface that extends infinitely in all directions. It further states that for any three non-collinear points, there exists exactly one plane passing through them.Now, planes can either be parallel or they can possibly intersect each other in a line and the three collinear points must not lie on the same lineIn conclusion, looking at the question we can say that a plane contains at least 3 points on the same line.
