Answer:
4 11/16 m²
Step-by-step explanation:
The formula for the area of a rectangle = Length × Width
From the question:
Length = 1 1/4 m
Width = 3 3/4m
Area of the rectangle =
1 1/4 m × 3 3/4 m
= 5/4 m × 15/4 m
= 75/16 m²
= 4 11/16 m²
Area of the rectangle = 4 11/16 m²
Autumn takes 39 minutes to walk to work.
After getting a new job, the time it takes
Autumn to walk to work has decreased by
35%. How many minutes does it take
Autumn to walk to work now?
We are required to calculate how many minutes does it take Autumn to walk to work now
The number of minutes does it take Autumn to walk to work now is 25.35 minutes
Time taken to walk to work = 39 minutes
Percentage decrease = 35%
Decrease in time = 35% of 39 minutes
= 35/100 × 39 minutes
= 0.35 × 39 minutes
= 13.65 minutes
Number of minutes does it take Autumn to walk to work now
= 39 minutes - 13.65 minutes
= 25.35 minutes
Therefore, the number of minutes does it take Autumn to walk to work now is 25.35 minutes

6900 dollars is placed in account with an annual interest rate of 8.25%. How much will be in the account after 26 years, to the nearest cent.
Answer:
$54196.92
Step-by-step explanation:
6900x1.0825^26
1.0825 is the multiplier
The correct answer is $54196.92.
Step by step =
6900x1.0825^26 = 54196.92.
How do you calculate the annual interest rate?
The formula and calculations are as follows:
Effective annual interest rate = (1 + (nominal rate / number of compounding periods)) ^ (number of compounding periods) - 1.For investment A, this would be: 10.47% = (1 + (10% / 12)) ^ 12 - 1.And for investment B, it would be: 10.36% = (1 + (10.1% / 2)) ^ 2 - 1.Is the interest rate annual or monthly?
The interest rate is the amount a lender charges a borrower and is a percentage of the principal of the amount loaned. The interest rate on a loan is typically noted on an annual basis known as the annual percentage rate (APR).

Step-by-step explanation:
Bert made 3 batches of his uncle's signature spicy wing sauce for a barbecue last weekend.
He didn't want the sauce to be too spicy, so he tweaked the recipe, reducing the amount of
hot sauce he put in each batch by 2 ounces. Bert used 24 ounces of hot sauce in all to make
the wing sauce.
Which equation can you use to find u, the amount of hot sauce Bert's uncle usually puts in
each batch of spicy wing sauce?
3(u - 2) - 24
2(0 - 3) - = 24
3u - 2 = 24
2u - 3 = 24
How much hot sauce does Bert's uncle usually put in each batch of spicy wing sauce?
Write your answer as a whole number or a simplified fraction.
ounces
Algebraic equations are equations that have coefficients and unknown variables in them.
The equation to show how many ounces of spicy sauce Bert's uncle usually put in is given as: 3(u - 2) = 24
The amount of hot sauce Bert's uncle usually puts in each batch of spicy wing sauce is 10 ounces.
a) We are told in the question that Bert made 3 batches of his uncle's spicy sauce. He reduced the amount of hot sauce and used 2 ounces in each batch. He used 24 ounces of hot sauce in all to make the wing sauce.Let's represent each ounce of hot sauce as u
Hence, the equation to show how many ounces of spicy sauce Bert's uncle usual put in is given as:
3(u - 2) = 24
b) How much hot sauce does Bert's uncle usually put in each batch of spicy wing sauce?The amount of hot sauce Bert's uncle puts in the spicy wing sauce
3(u - 2) = 24
3u - 6 = 24
Collect like terms
3u = 24 + 6
3u = 30
Divide both sides by 3
u = 30/3
u = 10
Bert's uncle puts 10 ounces of hot sauce in the spicy wing sauce.

Answer:
Step-by-step explanation:
there are several ways. if u have angels use cos or sin therom. if u have a 90 degree angle use The Pythagorean Theorem. send it completely
Answer:
Before one can solve for the width of a rectangle(the value of the area or perimeter must be given and the length)
Using the area
Length = l
Width =w
Area = a
a = l × w ; a = lw
w = a/l
using perimeter(p)
p = 2(l+w)
p/2 = l+w
p/2 - l = w
w = p/2 -l

Step-by-step explanation:
If everything is kept in terms of x then:
For part A the general area would just be side times side.
Here it would be (30x)(4x)
=[tex]120x^{2}[/tex]
For part B since you have 5 sections divide the long side by 5.
[tex]\frac{30x}{5} =6x[/tex]
Then multiply by the other side of the rectangle to find the area of one section.
6x(4x)=[tex]24x^{2}[/tex]

Step-by-step explanation:
The procedure for solving simultaneous linear equations now called Gaussian elimination appears in the ancient Chinese mathematical text Chapter Eight: Rectangular Arrays of The Nine Chapters on the Mathematical Art. Its use is illustrated in eighteen problems, with two to five equations.[4]
Systems of linear equations arose in Europe with the introduction in 1637 by René Descartes of coordinates in geometry. In fact, in this new geometry, now called Cartesian geometry, lines and planes are represented by linear equations, and computing their intersections amounts to solving systems of linear equations.
The first systematic methods for solving linear systems used determinants, first considered by Leibniz in 1693. In 1750, Gabriel Cramer used them for giving explicit solutions of linear systems, now called Cramer's rule. Later, Gauss further described the method of elimination, which was initially listed as an advancement in geodesy.[5]
In 1844 Hermann Grassmann published his "Theory of Extension" which included foundational new topics of what is today called linear algebra. In 1848, James Joseph Sylvester introduced the term matrix, which is Latin for womb.
Linear algebra grew with ideas noted in the complex plane. For instance, two numbers w and z in {\displaystyle \mathbb {C} }\mathbb {C} have a difference w – z, and the line segments {\displaystyle {\overline {wz}}}{\displaystyle {\overline {wz}}} and {\displaystyle {\overline {0(w-z)}}}{\displaystyle {\overline {0(w-z)}}} are of the same length and direction. The segments are equipollent. The four-dimensional system {\displaystyle \mathbb {H} }\mathbb {H} of quaternions was started in 1843. The term vector was introduced as v = x i + y j + z k representing a point in space. The quaternion difference p – q also produces a segment equipollent to {\displaystyle {\overline {pq}}.}{\displaystyle {\overline {pq}}.} Other hypercomplex number systems also used the idea of a linear space with a basis.
Arthur Cayley introduced matrix multiplication and the inverse matrix in 1856, making possible the general linear group. The mechanism of group representation became available for describing complex and hypercomplex numbers. Crucially, Cayley used a single letter to denote a matrix, thus treating a matrix as an aggregate object. He also realized the connection between matrices and determinants, and wrote "There would be many things to say about this theory of matrices which should, it seems to me, precede the theory of determinants".[5]
Benjamin Peirce published his Linear Associative Algebra (1872), and his son Charles Sanders Peirce extended the work later.[6]
The telegraph required an explanatory system, and the 1873 publication of A Treatise on Electricity and Magnetism instituted a field theory of forces and required differential geometry for expression. Linear algebra is flat differential geometry and serves in tangent spaces to manifolds. Electromagnetic symmetries of spacetime are expressed by the Lorentz transformations, and much of the history of linear algebra is the history of Lorentz transformations.
The first modern and more precise definition of a vector space was introduced by Peano in 1888;[5] by 1900, a theory of linear transformations of finite-dimensional vector spaces had emerged. Linear algebra took its modern form in the first half of the twentieth century, when many ideas and methods of previous centuries were generalized as abstract algebra. The development of computers led to increased research in efficient algorithms for Gaussian elimination and matrix decompositions, and linear algebra became an essential tool for modelling and simulations.[5]
Vector spaces
Main article: Vector space
Until the 19th century, linear algebra was introduced through systems of linear equations and matrices. In modern mathematics, the presentation through vector spaces is generally preferred, since it is more synthetic, more general (not limited to the finite-dimensional case), and conceptually simpler, although more abstract.
A vector space over a field F (often the field of the real numbers) is a set V equipped with two binary operations satisfying the following axioms. Elements of V are called vectors, and elements of F are called scalars. The first operation, vector addition, takes any two vectors v and w and outputs a third vector v + w. The second operation, scalar multiplication, takes any scalar a and any vector v and outputs a new vector av. The axioms that addition and scalar multiplication must satisfy are the following. (In the list below, u, v and w are arbitrary elements of V, and a and b are arbitrary scalars in the field F.)[7]
