What is a perimeter?The total length of a shape's boundary is referred to in geometry as the perimeter of the shape. A shape's perimeter is calculated by adding the lengths of all of its sides and edges. Its dimensions are expressed in linear units like centimetres, metres, inches, and feet.
A regular polygon's perimeter is equal to the product of all of its sides, which is equal to the number of sides times the length of a side.
We use the general method to get the perimeter of an irregular shape since the sides of an irregular polygon might not all be the same length.
Therefore, the irregular polygon's perimeter equals the total of its sides.

A 2-lb sample of an unknown liquid occupies a volume of 47.6 in.3 for the liquid determine (a) the specific volume, in ft3/lb, and (b) the density, in lb/ft3.
The specific volume is 0.0135 ft^3
The density is 74.07 lb/ft^3
Here,
A 2-lb sample of an unknown liquid occupies a volume of 47.6 in^3.
We have to find the specific volume and density.
What is Specific volume?
Volume is a measure of the amount of space occupied by an object.
Now,
Mass = 2 lb
Volume = 47.6 in^3
= 0.027 ft^3
Hence, Specific volume = volume/ mass = 0.027/2 = 0.0135 ft^3
And, Density = mass/ volume = 2/ 0.027 = 74.07 lb/ft^3
So, The specific volume is 0.0135 ft^3
The density is 74.07 lb/ft^3

The converse statement is: If it is daytime, then the sun is out.
The inverse statement is: if the sun is not out, then is not daytime.
The contrapositive statement is: if it is not daytime, then the sun is not out.
How to find the converse, inverse, and contrapositive statements?
If we have two propositions P and Q, then we have a conditional statement:
If P then Q.
The converse statement is: if Q then P
The inverse statement is: if Not P, then Not Q.
The contrapositive statement is: if Not Q, then Not P.
The conditional statement is:
"If the sun is out, then it is daytime"
So we have:
P = the sun is out.
Q = it is daytime.
Then the 3 statements are:
The converse statement is: If it is daytime, then the sun is out.
The inverse statement is: if the sun is not out, then is not daytime.
The contrapositive statement is: if it is not daytime, then the sun is not out.

Anne’s family drives to her uncle’s house for vacation, and they take two separate cars. anne’s car travels 383.5 miles between 10:15 am and 4:45 pm. the equation y = 58x represents the relationship between the distance, y, in miles and the time, x, in hours that anne’s sister’s car traveled. if both cars are traveling at constant rates, which car â€" anne’s or her sister’s â€" would you expect to arrive at their uncle’s house first? explain how you know.
Anne's family wouldn't have gotten there until about 5:55 pm.
How Distance is that?
Distance is the sum of an object's movements, regardless of direction. Distance can be defined as the amount of space an object has covered, regardless of its starting or ending position.The arrival time is the travel time added to the start time. The travel time is given by ...
time = distance/speed
At 50 miles per hour, the travel time would be ...
time = 383.5/50 = 7.67 . . . . hours
The fraction of an hour is ...
(0.67 hours)×(60 min/hour) = 40.2 min
Adding the travel time to the start time, we get an arrival time of ...

What is an expression?
Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Given that;
The difference of two numbers is 12.
And, one of the numbers is 19.
Now,
Let two numbers are x and y.
So, We get;
x + y = 12
Here, one of the numbers is 19.
So, x = 19
We get;
x + y = 12
19 + y = 12
y = 12 - 19
y = - 7
Thus, The other number will be - 7.
Yes, There is only one answer.

The area of a rectangular carpet is given by the quadratic function A(x) = x(x + 30), where A(x) is the area and x is the width of the carpet in feet. What are the restrictions on the domain of the function and its inverse?
The inverse of the function is; f⁻¹(x) = - 15 ± √(x + 225)
What is the Inverse of the Function?We have been given a quadratic function f(x) = x(x + 30) and we need to restrict the domain such that it becomes a one to one function.
Now, the given function can also be written in vertex form as;
f(x) = (x + 15)² - 225
We know that vertex of this quadratic function occurs at (-15, -225).
Further, we know that range of this function is (-225, ∞).
If we restrict the domain of this function to either (-∞, -225) or (-225, ∞) , it will become one to one function.
Let us know find its inverse;
y = (x + 15)² - 225
Upon interchanging x and y, we get:
x = (y + 15)² - 225
Solving for y gives;
y = - 15 ± √(x + 225)

The angle measures, in order from least to greatest, of the dilated image 45°,55° and 80°.
A dilation is a function f from a metric space M into itself that satisfies the identity d=rd for all points x, y \in M, where d is the distance from x to y and r is some positive real number. In Euclidean space, such a dilation is a similarity of the space.
Euclidean space, In geometry, a two- or three-dimensional space in which the axioms and postulates of Euclidean geometry apply; also, a space in any finite number of dimensions, in which points are designated by coordinates (one for each dimension) and the distance between two points is given by a distance formula.
Dilations preserve angle measures, regardless of the scale factor. Therefore, the angle measures of the image will be the same of that of the pre-image, so our answer is still 45 °, 55 °, and 80 °.

The function f(x) = x² is transformed and became g(x) = 3(x+2)² -1 has the graph of g(x) is wider than f(x) and is shifted to the left 3 units and down 3 unit.
What are graph transformations ?By applying suitable graph transformation we can shift, stretch, shrink, a given graph along x and y axis.
According to the given question given a graph f(x) = x² and g(x) is 3(x+3)² - 3.
Let us break transformations of g(x) one by one.
g(x) = 3f(x) which implies it's amplitude or vertical stretch is increased by a factor of 3.
Now, g(x) = 3(x+3)² implies the graph is shifted towards left by 3 units as x + 3 = 0 is x = -3.
Now, g(x) = 3(x+3)² - 3 implies that the whole graph has been shifted 3 units down along the y axis.
Hence the graph of g(x) is wider than f(x) and is shifted to the left 3 units and down 3 units.
