In the evening Amy swims for 30 minutes, as per the given condition.

The equation model is defined as the model of the given situation in the form of an equation using variables and constants.

Here,
Let Amy swim x minutes in the morning,
So in the evening, she swims for 1 1/2 × x minutes,
According to the quesiton,
Each day she swims for 50 minutes.
x + 1 1/2 x = 50
5x/ 2 = 50
x = 20 minutes

Now,
In the evening,
= 3/2x
= 3/2{20}
= 30 minutes

Thus, in the evening Amy swims for 30 minutes.

A system of equations comprises two or more equations and seeks common solutions to the equations. "A system of linear equations is a set of equations which are satisfied by the same set of variables."

A finite collection of equations for which we searched for the common solutions is referred to as a system of equations, also known as a set of simultaneous equations or an equation system. Similar to single equations, a system of equations can be categorized. In everyday life, systems of equations are used to model issues when the unknown values may be represented by variables.

A system of equations has only one unique solution if the L.H.S. and R.H.S. of all the provided equations in the system are identical when the variable or point of intersection of the lines representing those equations is substituted.

A percentage can be larger than 100 and a fraction can be greater than 1.

A percentage is a figure or ratio that can be stated as a fraction of 100 in mathematics. If we need to determine a percentage of a number, multiply it by 100 and divide it by the total. So, a part per hundred is what the percentage refers to. Percent signifies for every 100. The sign "%" is used to denote it.

A percentage can be larger than 100 and a fraction can be greater than 1. We are limited to looking at the whole only when the fraction or percentage relates to a portion of it.

In addition to being stated as a decimal or a fraction, a percentage is a number that indicates how many out of 100 it is. Three for the price of one! Simply enter the % as the numerator and 100 as the denominator to convert the percentage to a fraction.

Therefore, the correct answer is 35%.

What is a linear equation?

A linear equation is one that has the highest degree of 1 possible. This indicates that there are no variables in a linear equation with exponents greater than 1. Such an equation on the graph, forms a straight line.

We are given equation- 2(n + 1) = 2n

On distributing, we get

⇒2n+2=2n

Now, subtracting 2 from both sides, we get

⇒2n+2-2=2n-2

⇒2n=2n-2

On subtracting 2n from both sides, we get

The values for the trigonometric functions for given coordinates are,

sin θ = 0.406, cos θ = 0.914,

tan θ = 0.444, cosec θ = 2.46,

sec θ = 1.04,  cot θ = 2.25

The ratio of sides of a right-angled triangle is the basis for trigonometric functions and identities. Trigonometric formulas are used to determine the sine, cosine, tangent, secant, and cotangent values for the perpendicular side, hypotenuse, and base of a right triangle.

Given the standard position on the coordinate plane with the point (9,4)

x = 9 and y = 4

Start by sketching the related triangle and the terminal side in the standard position.

Calculate the hypotenuse's missing side using the Pythagorean Theorem.

so h² = 4² + 9²

h² = 16 + 81

h² =97

h = √97

so sinθ = y/h = 4/√97 = 0.406

cosθ = x/h = 9/√97 = 0.914

tanθ = y/x = 4/9 = 0.444

cosecθ = h/y = √97/4 = 2.46

secθ= h/x = √97/9 = 1.04

cotθ = x/y = 9/4 = 2.25

Hence values for functions are,

sin θ = 0.406, cos θ = 0.914,

tan θ = 0.444, cosec θ = 2.46,

sec θ = 1.04,  cot θ = 2.25

Answer: Based on the information provided, Bank Y is the best option for Henry. Although Bank Y has a $25 minimum balance requirement, Henry only usually has $300 in his account, so this will not be a problem. Furthermore, Bank Y has no monthly fees as long as Henry uses his check card less than 6 times per month, which he is likely to do. Additionally, Bank Y offers online banking services, which Henry is interested in.

Bank X has a monthly fee of $7 if the balance stays below $500, which Henry is likely to incur as he usually only has $300 in his account. Bank Z has a $5 monthly fee regardless of the balance, which is not ideal for Henry.

In terms of ATM fees, Bank Y has the lowest fee at $1.50 per transaction, which is lower than the fees charged by Bank X and Bank Z.

So, based on the information provided, Bank Y is the best option for Henry.

The inverse function returns the original value for which a function gave the output.

A function that can reverse into another function is known as an inverse function or anti function. In other words, the inverse of a function "f" will take y to x if any function "f" takes x to y. When a function is written as "f" or "F," its inverse is written as "f-1" or "F-1." Here, (-1) should not be confused with an exponent or a reciprocal.

Angela makes 150 necklaces on average each month making necklaces for 2.5 hours each day.

What is an average of given data?

An average of a list of data is a mathematical expression for the centre value of a set of data. It is defined mathematically as the ratio of the total of all the data to the number of units in the list. In statistics, the average of a particular collection of numerical data is also known as the mean.

for e.g.

The average of 2, 3, and 4 equals (2+3+4)/3 = 9/3 = 3. As a result, the central value of 2,3, and 4 is 3. Thus, the definition of average is to determine the mean value of a set of data.

Now,

Angela works 20 days in a month making necklaces for 2.5 hours each day

so, Total hours she worked = 20*2.5

                                              = 50 hours

She makes 3 necklaces in an hour

Hence,

Necklaces made by her on average in a month = 50*3

                                                                       =150/month

The first step to solve the equation -1/2(x+4) = 6 is to multiply both sides by -2

A linear equation is an algebraic equation where each term has an exponent of 1 and when this equation is graphed, it always results in a straight line.

The equation -1/2( x+4) = 6 is an example of linear equation. It is a linear equation with one variable and x is the variable.

The equation -1/2(x+4) = 6

multiply both sides by -2

-1/2( x+4) ×-2 = 6 ×-2

x+4 = -12

Step-by-step explanation:

Point-slope form is [tex]y - y_{1} = m(x - x_{1} )[/tex]

y1= -7 , x1= -5

Substitute (-5,-7) and m=-7 into the equation

y - ( -7) = -7(x - (-5))

y - ( -7) = -7(x + 5)

y + 7 = -7(x + 5)

The number of solutions to the equation y = ( 7/10 )x + 6y is infinite number of solutions as the equations are the same

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

The total of the measurements of the two non-adjacent internal angles of a triangle determines the size of its exterior angle.

The angle created when a transversal cuts one of two lines and is located outside of the line. It describes the angle between a side of a polygon and an expanded neighboring side.

Exterior angles are those that run parallel to a polygon's inner angles but are located outside of it. The sum of the two internal opposed angles determines the size of an outside angle.

The angle between any side of a form and a line that extends from the next side is known as the exterior angle. The result of adding the interior and outside angles is a 180° straight line. "Supplementary Angles" is what they are.
