The term "length" is used to describe an object's size or the separation between two points. Lindsey must buy 4 feet of the board for the ramp itself.
What is meant by length?The term "length" refers to the measurement or size of something from end to end. In other terms, it is the greater of the upper two or third dimension of a geometric shape or object.
Distance exists estimated in length. The length contain the dimension of distance in the International System of Quantities. The majority of measurement systems select a base unit for length from which all other units exists derived. The meter serves as the foundational unit of length in the International System of Units.
A rectangle, for instance, has length and width as its dimensions.
1/x = 15°
x = 1/sin 15°
simplifying the above equation, we get
x = 3.9ft

A 45° - 45° - 90° right triangle is inscribed in a circle. If the radius of the circle is given, explain how to find the lengths of the right triangle's legs.
Answer:
X = √2 R , where X is the length of the legs as R is the length of the radius .
Step-by-step explanation:
The opposite sides of two same angled triangle is also same . So in this case we can say two legs are in same length as their opposite angles are same (45°)
Now , suppose the given radius is R (look at the diagram) then total diameter is 2R ( DIAMETER = 2 × RADIUS )
Now , we will consider the length of the legs are X ( as the are same ).
Now, we will apply Pythagoras theorem ( The squares on the legs of a right triangle is equal to the square on the hypotenuse . )
∵ X² + X² = (2R)²
or , 2X² = 4R²
or, X² = 2R²
We will root both side
X = √2R
So , X is the length of the legs as R is the length of the radius .

What is slope?A number that describes a line's direction and steepness is known as the slope or gradient of a line in mathematics. There is no obvious reason why the letter m is used to represent slope, although it first appears in English in O'Brien (1844), who wrote the equation for a straight line as "y = mx + b," and it may also be found in Todhunter (1888), who wrote it as "y = mx + c."
Let us write the given data in slope-intercept form that is
y = m(x) + b
where m = slope of the line
b = y-intercept
So substituting the values we get
0 = 32(-5) + b
-b = -160
b = 160
so we have the slope intercept form
0 = 32(-5) + 160

Answer:
Common difference = x - 2.
Step-by-step explanation:
Differences:
-2x - 9 - (-3x - 7)
= -2x - 9 + 3x + 7
= x - 2
-x - 11 - (-2x - 9)
= - x - 11 +2x + 9
= x - 2
So, it is Arithmetic.
Answer:
Arithmetic sequence.
Common difference = -x - 11
Step-by-step explanation:
This is an arithmetic sequence.
-3x - 7, -2x - 9, -x - 11, ...
Find the common difference.
Common difference =second term - first term.
= -2x - 9 - (-3x - 7)
= -2x - 9 + 3x +7
= -2x + 3x - 9 + 7 {Combine like terms}
= x - 2
If we add the common difference to the second term, we will get the third term.
Third term = second term + common difference
= -2x - 9 + x - 2
= -2x + x - 9 - 2
= -x - 11.
Hence this is an arithmetic sequence.
A square is inscribed in a circle. What is the ratio of the area of the circle to the area of the square?
The side of the square inscribed in a square be a units then the required ratio is π : 2.
What is an inscribed square?
A square is inscribed in a circle or a polygon if its four vertices are on the circle's circumference or the polygon's sides.
Inscribed in the circle is a square that fits snugly inside a circle. The square's corners will touch but not intersect the circle's boundary, and the diagonal of the square will equal the diameter of the circle. Furthermore, as with any square's diagonal, it equals the hypotenuse of a 45°-45°-90° triangle.
Let the side of the square inscribed in a square be a units.
Hence, the required ratio is 2 : 1.
Let ABCD be a square inscribed in a circle of radius 'r'.
Now, the diameter of the circle is the diagonal of the square.
Therefore, BD = 2r.
In △BDC, using Pythagoras theorem
[tex]BC^2+CD^2=BD^2[/tex]
⇒ [tex]a^2+a^2=(2r)^2[/tex]
⇒ [tex]2a^2=4r^2[/tex]

y = 2x - 1 , 3x - y = -1
By substitution, the solution of the system of equations, y = 2x - 1 and 3x - y = -1, is (-2 , -5).
A system of linear equations is a set of two or more equations which includes common variables. To solve system of equations, we must find the value of the unknown variables used in the equations that must satisfy both equations.
There are three methods that can be used to solve system of linear equations.
1. Elimination
2. Substitution
3. Graphing
Using substitution method, given two linear equations in x and y,
y = 2x - 1 (equation 1)
3x - y = -1 (equation 2)
Since the first equation is already expressed in y in terms of x, substitute the value of y to the second equation.
3x - y = -1 (equation 2)
3x - (2x - 1) = -1
3x - 2x + 1 = -1
Combining all terms containing the variable x on one side and the constants on the other side of the equality, and solving for x.
3x - 2x + 1 = -1
3x - 2x = -1 - 1
x = -2
Substitute the value of x in the first equation.
y = 2x - 1 (equation 1)
y = 2(-2) - 1
y = -4 - 1
y = -5
Hence, the solution of the given system of equations is (-2 , -5).

The sequence 3/32, 3/16, 3/8, 3/4, 3/2, 3,6, ... is a geometric sequence with common ratio 2.
To determine whether the sequence is an arithmetic or geometric one, we need to check how the consecutive terms relate to each other.
If it is an arithmetic sequence, then:
a(n) = a(n-1) + d
where d is the common difference.
If it is a geometric sequence, then:
a(n) = a(n-1) . r
where r is the common ratio.
The given sequence is:
