Answer: The Commutative Law of Addition states that the order in which numbers are added does not affect the result. This means that for any two numbers a and b, we have a + b = b + a.

We can use the Commutative Law of Addition to rewrite the equation 177 + 563 = 740 as follows:

177 + 563 = 740

563 + 177 = 740

Both of these equations are equivalent to the original equation, because they represent the same mathematical statement.

Note that in the first equation, we simply reordered the terms of the original equation. In the second equation, we added the numbers in a different order, but the result is still the same.

The other equations you provided are not equivalent to the original equation and do not use the Commutative Law of Addition.

Customers are subject to a charge known as sales tax when they buy goods and services.

It is a pass-through tax, which means you must collect it from clients and send the money to your state or local government. the seller do not contribute sales tax.

The sales tax is first calculated by

= price after tax - price before tax

= 513 - 475

= 38

sales tax percentage is calculated using the formula

= (Tax amount / Price before tax) × 100%

The area of the triangle from the vertices is 27 square units

From the question, we have the following parameters that can be used in our computation:

$A\left(2,\ -2\right)$ , $B\left(4,\ -2\right)$ , and $C\left(6,\ -11\right)$ .

Represent the vertices properly

So, we have

A = (2, -2)

B = (4, -2)

C = (6, -11)

The area of the triangle is calculated using

Area = 0.5 * |Ax(By - Cy) + Bx(Ay - Cy) + Cx(Ay - By)|

Substitute the known values in the above equation, so, we have the following representation

Area = 0.5 * |2 * (-2 + 11) + 4 * (-2 + 11) + 6 * (-2 + 2)|

Evaluate the sum of products

Area = 0.5 * |54|

Remove the absolute bracket

Area = 0.5 * 54

Evaluate

Area = 27

Hence, the area of ABC with vertices is 27 square units

The measure of Angle JKL mJ = 159.4°, mK = 3.8°, and mL = 16.8°.

A ray is rotated about its endpoint, or vertex, to create an angle. The rotational difference between a ray's starting and ending positions is what is measured by an angle's degree.

If x = mJ, y = mK, and z = mL, then

Angle L exceeds Angle K by thirteen, hence z = y + 13 is the result (1)

Since angle J exceeds angle K by a factor of 7, x = 7(6y) = 42y (2)

X + Y + Z = 180 because the triangle's angles add up to 180°.

In place of (1) and (2) (3).

42y + y + (y + 13) = 180

44y + 13 = 180

44y = 167

y = 3.8°

x = 42y = 159.4°

z = y + 13 = 16.8°

If the slope is negative, the function is downward-sloping because y falls off as x rises. If the slope is zero, y remains constant—a horizontal line—and does not vary.

A line's steepness and direction are measured by the line's slope.

Without actually using a compass, determining the slope of lines in a coordinate plane can assist in forecasting whether the lines are parallel, perpendicular, or none at all

Any two different points on a line can be used to calculate the slope of any line.

A line's slope is determine by how its y coordinate changes in relation to how its x coordinate changes. y and x are the net changes in the y and x coordinates, respectively.

Two locations located on a straight line can be used to determine a line's slope. We can use the slope of line formula if we know the two spots' coordinates. These two points' coordinates should be-

P1 = (x1, y1) and P2 = (x2, y2)

Hence, If the slope is negative, the function is downward-sloping because y falls off as x rises. If the slope is zero, y remains constant—a horizontal line—and does not vary.

The bare minimum required is $4500 to reserve 5 blocks totaling at least 34 rooms.

In mathematics, a relationship between two expressions or values that are not equal to each other is called "inequality".

Here,

The number of rooms Joe company needs is 50. Let the number of rooms needed be n, this can be represented by the inequality:

n ≥ 50

Joe has already reserved 16 rooms, therefore the number of additional rooms needed to be reserved = 50 - 16 = 34 rooms. At least 34 rooms have to be reserved, if B is the number of additional blocks that Joe reserves, the inequality is:

B ≥ 34

Each block contains 8 rooms therefore the minimum number of block (a) needed to be reserved = 34/8 = 4.25 = 5 to the next whole number. Therefore the minimum number of blocks needed is given as:

a ≥ 5

Since each block cost $900, let c represent the minimum amount of money needed, therefore the least amount of money needed is given as:

c = $900(5) = $4500

c ≥ $4500

The least amount of money needed is $4500 for booking 5 blocks that will reserve at least 34 rooms.

The interest rate would be 13%.

What is the simple interest?

Simple Interest (S.I.) is the method of calculating the interest amount for a particular principal amount of money at some rate of interest. For example, when a person takes a loan of Rs. 5000, at a rate of 10 p.a. for two years, the person's interest for two years will be S.I. on the borrowed money.

To find the interest rate, we can use the formula for simple interest:

I = Prt

where I is the amount of interest earned, P is the principal (the initial amount of money deposited), r is the interest rate, and t is the time in years.

In this case, we know that I = $3,900, P = $10,000, and t = 3 years. We can use this information to solve for r:

I = Prt

$3,900 = $10,000r3

r = $3,900/($10,000*3)

r = 0.13 or 13%

Hence, the interest rate is 13%.

In which the parameters are listed as follows:

The points for the railroad are given as follows:

(-8, 0) and (0,5).

When x = 0, y = 5, hence the intercept is of:
