Michelle pays $185.76 for a table and chair. If the actual price is $172, what is the sales tax rate?

Answer:

Yeah, they are not equal.

Step-by-step explanation:

Given statement,

→ -3 to the second power is not equal to (-3) to the second power.

Forming the equation,

→ -3² ≠ (-3)²

Let's check the equation,

→ -3² = (-3)²

→ -(3)² = (-3)²

→ -9 ≠ 9

→ LHS ≠ RHS

Hence, they are not equal.

Area is the total amount of space that an object's shape or a flat (2-D) surface occupy.

Create a square on paper by using a pencil. Two dimensions make it up. A shape's area on paper is the space it takes up.

Imagine that your square is made up of smaller unit squares.

The area of a figure is equal to the number of unit squares required to completely cover the surface area of a particular 2-D shape. Square cms, square feet, square inches, square meters, etc. are a few common units for measuring area.

To get the area of the square figures presented below, draw unit squares with 1-centimeter sides. Therefore, the shape will be measured.

Hence, 5 scoops of powder are combined with 8 glasses of water by Noah.

The value of the equation 3d/ac x 2ad/30 is ( d² / 5c )

What is an Equation?

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

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the equation be represented as A

Now , the value of A is given by

A = 3d/ac x 2ad/30   be equation (1)

On simplifying the equation , we get

A = 3d/ac x 2ad/30  

A = 6ad² / 30ac

On further simplification of the equation , we get

The value of A = 1/5 ( ad² / ac )

The value of A = 1/5 ( d²/c )

Therefore , the value of A is  ( d² / 5c ) or A = 1/5 ( d²/c )

Hence , The value of the equation 3d/ac x 2ad/30 is ( d² / 5c ) or

A = 1/5 ( d²/c )

Answer:

9/10 =0.9

Step-by-step explanation:

We have been given to calculate 1 1/2 times 3/5 . First of all ,we shall convert 1 1/2 ( a mixed fraction form) to a proper fraction form .

1 1/2 is actually 1 + 1/2 =3/2

1 1/2 X 3/5  =3/2 X 3/5 =9/10

9/10  is actually 0.9

Therefore we have finally converted this into division sentence too

If Alan had ran 1 10/11 kilometer and walked the ret so his remaining distance from school is 6 5/11 kilometer.

Distance is the sum of an object's movements, regardless of direction. Distance can be defined as the amount of space an object has covered, regardless of its starting or ending position.

Learn how to apply the Pythagorean theorem to find the distance between two points using the distance formula. The Pythagorean theorem can be rewritten as d=√((x_2-x_1)²+(y_2-y_1)²) to calculate the separation between any two locations.

As the total travel of alan from his school is

=8 2/3 kilometer

according to given condition;

he has traveled;

=1 10/11 kilometer

so his remaining travel from his school is;

=8 2/3 kilometer-1 10/11 kilometer

A rectangle is constructed on a semicircle so that the length equals the diameter. The width of the rectangle is approximately 10.65 inches.

Generally, Let the width of the rectangle be x. Then the length of the rectangle is 3x.

The diameter of the semicircle is also the length of the rectangle, so it is 3x.

The area of the rectangle is x*(3x) = 3x^2. The area of the semicircle is (1/2)πr^2, where r is the radius of the semicircle. Since the diameter of the semicircle is 3x, the radius is (3x)/2. The area of the semicircle is (1/2)π((3x)/2)^2 = (9/8)πx^2.

The total area of the figure is the sum of the area of the rectangle and the area of the semicircle. We can set up the equation:

3x^2 + (9/8)πx^2 = 750

(21/8)πx^2 = 750

x^2 = 750/(21/8)*π

x = √(750/(21/8)*π)

To find the approximate dimensions of the rectangle, we can use the fact that pi is approximately 3.14. This gives us:

x = √(750/(21/8)*3.14)

= √(750/6.71)

= √(112.64)

= approximately 10.65 inches.

The width of the rectangle is approximately 10.65 inches. The length of the rectangle is 3 times the width, so it is approximately 31.95 inches.

The chance that a student is selected at random from the class who passed the exam and finished the assignment is 0.2105

Probability refers to potential. The occurrence of a random event is the subject. Probability values are limited to the range of 0 to 1. Its fundamental notion is that something is probable to occur. It is the proportion of favorable events to all other events.

A exam and an assignment were due on the same day in a math class with 19 pupils.

There were 14 students that finished the assignment, and 11 of them completed the test.

3 pupils both failed the exam and didn't finish the assignment.

Then the probability that a student is chosen randomly from the class passed the test and completed the homework will be

The number of the student who has done at least one assignment or passed the test is 19 - 3 = 16

n(A) = passes student

n(B) = given assignment

Then we have

n(A ∩B) = n(A) + n(B) - n (A ∪B )

n(A ∩B) = 11 + 14 - 16

n(A ∩B) = 9

Then the probability will be

P = 9C2 /19C2

P = 36/171

P = 0.2105

Using mathematical operations, we can conclude that the length of LK is 1.25 units in triangle JKL.

A mathematical "operation" is indeed the method by which a value utilizes operands and a math operator.

The supplied operands or numbers must conform to a set of predefined rules that are connected to the symbol of the math operator.

Parentheses, Exponents, Arithmetic, Division, and Addition Simple arithmetic is also known as PEMDAS (from left to right).

So, we know that the given triangles are similar:

Then, the length of line LK will be:

JK/ST = LK/UT

Solve this as follows:

JK/ST = LK/UT

2.5/10 = LK/5

10LK = 2.5(5)

10LK = 12.5

LK = 12.5/10

LK = 1.25

Therefore, using mathematical operations, we can conclude that the length of LK is 1.25 units in triangle JKL.

The Poisson distribution would be used to calculate the likelihood that different counts of the same event will occur within a constrained time period. It is viewed as a discrete distribution since it evaluates counts. The distribution displays identical mean and dispersion values.

The pmf of the Poisson distribution is

[tex]p(x)=\frac{e^{\lambda} \lambda^{x}}{x!}[/tex]

The mean total number of small business failures λ=14

Let x represent the number of failed small businesses in a given month.

X~P(14)

X follows the Poisson distribution since the likelihood of failure stays constant for two months and the mean number of failures per month is 14.

The likelihood that precisely four small firms would fail in a given month must be calculated.

I think it's y=x² +6 because this is a quadratic equation

Answer:

i think 3

Step-by-step explanation:

Answer:

  a)  y = 16/x²

  b)  x = 4/5

Step-by-step explanation:

You want the equation for y in terms of x when y is inversely proportional to the square of x, and y is 16 when x is 1. Further, you want the value of x when y is 25.

The wording "inversely proportional to the square" means the form of the equation is ...

  y = k/x² . . . . . . where k is the constant of proportionality

The value of k can be found from the given (x, y) pair.

  k = x²y = (1)²(16) = 16

The equation is ...

  y = 16/x²

Solving for x gives ...

  x = √(16/y)

Then the value of x for y = 25 is ...

  x = √(16/25)

  x = 4/5

a local winery bottles 14 different white wines. to help customers with their purchasing choice, the winery offers customers 5 white wine tasting samples free of charge 2002 many ways does a customer have to choose 5 different white wines to taste, using the concept of combination formula.

The number of possible ways to choose items from a collection when the order of choice is irrelevant is determined using the combination formula. Combination, to put it simply, is the process of choosing items or things from a bigger group where order is irrelevant.

The combination formula is: n! / (n-r)! r! , where n is the total number of items (14 in this case) and r is the number of items being selected at once (5 in this case),

Plugging our numbers into the formula we get:

= 14! / (14-5)! 5!

= 2002

After simplifying, we get 2002.

So, there are 2002 ways of picking 5 different white wines to taste from a group of 14 local winery bottles.
