Answer: To find out how long it took the class to paint the whole mural, you need to first find out how many square feet the mural is. To do this, you can multiply the length and width of the mural together:

4.75 feet x 3.25 feet = 15.4375 square feet

You know that it takes 30 minutes to paint 1 square foot, so you can multiply the number of square feet by the time per square foot to find the total time:

15.4375 square feet x 30 minutes/square foot = 463.125 minutes

So, it took the class approximately 463.125 minutes to paint the whole mural. To convert it to hours, you can divide the minutes by 60:

463.125 minutes / 60 = 7.71875 hours

So, it took the class about 7.71875 hours to paint the whole mural.

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 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%.

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.

Step-by-step explanation:

Find 2 easy to read points: (1, -3) and (3, 0).

The expression (x-6)² is equivalent to (x-6)(x-6)

An expression is combination of variables, numbers and operators.

(x-6)²=(x-6)(x-6)

We know the algebraic identity that (a-b)²=a²+b²-2ab

(x-6)²=x²+6²-2x(6)

=x²-12x+36

Now we have to factorize the expression

Step-by-step explanation:

First look at the 130. Since we know all these lines are straight, that means 130 and the angle adjacent to it is a supplementary angle. This means that you can take 180 and subtract 130 to get the inside angle. Now that you have two of three angles of the triangle, you can take 180 and subtract both of the known angles to get your final answer.

Step-by-step explanation:

usually, when asked about the equation for a line, we give it in slope-intercept form :

y = ax + b

"a" is the slope, "b" is the y-intercept (the y-value when x = 0).

the graph tells us the y-intercept right away : 6

the scope is the ratio

y coordinate difference / x coordinate difference

when going from one point on the line to another.

I recommend to always look for points with integer coordinates (the line goes through a vertex of a grid square).

the y-intercept gives us the first point

(0, 6)

and then I see easily at the other end of the visible line :

(4, 10)

between these 2 points

x changes by + 4 (from 0 to 4).

y charges by + 4 (from 6 to 10).

the slope is then +4/+4 = 1

so, our equation is

y = x + 6

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

The inequality system represented by the graph is Option A: y = x + 3; y = x2 - 3x.

We can see from the inequality graph that one of the shaded zones is below the parabola and the other is between the parabola and the bottom of the line.

Due to the thickness of the boundary lines and the fact that both shaded regions are below their respective parabola and line borders, we will use the "less than or equal to" indications for each inequality.

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.

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.
