A large auditorium has stadium with stadium seating. There are 8 seats in the first row, 10 seats in the second row, 12 seats in the third row and 300 seats in the last row. How many rows of seats are in the auditorium

Answer:

48/5≈ 9 3/5

Step-by-step explanation:

12 is the same thing as 12/1

so your multiply fractions

4/5 times 12/1

numerator=top

denominator=bottom

so to multiply a fraction you multiply the numerator times the numerator

so in that case your multiplying 4 times 12

=48

to find the bottom half you multiply the denominator times the denominator

in that case is 5 times 1

=5

numerator/denominator

48/5

if you want to simplify it further simply divide 48/5

5 goes into 48 about 9 times

and were left with 3/5

so 9 and 3/5

Answer: neither

Step-by-step explanation:

To get rid of the fractions, we pick a useful number and multiply both sides of the equation by that number. The number is useful if multiplying eliminates all fractions.

If intersection of A & B null set and P(A) = 0.4, P(A ∪ B) = 0.9 then P(B) = 0.5

In mathematics, a set is a collection of distinct objects, called elements, which can be anything from numbers, to letters, to functions, or even other sets. The objects in a set are unordered, meaning their position or arrangement doesn't matter. Sets are often denoted using curly braces {} and the elements within the set are separated by commas.

For example, the set of positive even numbers less than 10 can be written as {2, 4, 6, 8}.

Given that,

A ∩ B = ∅,

P(A) = 0.4,

P(A ∪ B) = 0.9,

P(B) = ?

P(A ∪ B) = P(A) + P(B) - P(A ∩ B)

0.9 = 0.4 + P(B) - 0

P(B) = 0.9 - 0.4

       = 0.5

Hence, the probability of event B is 0.5

Answer:

Step-by-step explanation:

The formula to find arc length is

\(AL=\frac{\theta}{360}*\pi d\) where theta is the measure of the central angle and d is the diameter. If we are dealing with a semicircle, the measure of the central angle is 180 degrees. Filling in:

\(AL=\frac{180}{360}*\pi (18)\) which simplifies a bit to

\(AL=\frac{1}{2}*\pi (18)\) and a bit more to

AL = 9π. That answer is obviously in terms of π; if you need it in terms of whatever your measurement is (feet, inches, cm, etc.) the answer would be, rounded to the nearest tenth, 28.3 units

∠ GJK = 102°

Step-by-step explanation:

(2x + 92) and (3x + 63) are same- side interior angles and sum to 180° , so

2x + 92 + 3x + 63 = 180

5x + 155 = 180 ( subtract 155 from both sides )

5x = 25 ( divide both sides by 5 )

x = 5

Then

∠ GJK = 2x + 92 = 2(5) + 92 = 10 + 92 = 102°

The equivalent expression to 5/8)⁻¹ × (0.42)²  is the expression

(1.6)(0.42)²

Equivalent expressions can be defined as expressions that work the same even though they look different. If two algebraic expressions are equivalent, then the two expressions have the same value when we plug in the same value for the variable.

Generally, when two expressions are equivalent, they must be equal to one another. It can often be a simplification of the previous expression to give a resultant or concise value.

In the expression given;

(5/8)⁻¹ × (0.42)²

Taking the inverse of the first variable

(5/8)⁻¹ = 8/5

8/5 = 1.6

We can rewrite the expression as

(5/8)⁻¹ × (0.42)² = (1.6)(0.42)²

The expression (1.6)(0.42)² is equivalent to (5/8)⁻¹ × (0.42)²

Step-by-step explanation:

Given: \(y=x^2-x-6\)

To find: a factored form of the given equation

Solution:

The equation \(y=ax^2+bx+c\) can be written in factored form as \(y=a(x-r_1)(x-r_2)\).

To find the x-intercepts, put \(y=0\).

Graph of the equation \(y=a(x-r_1)(x-r_2)\) represents a parabola.

\(y=x^2-x-6\\=x^2+(-1)x-6\\=x^2+(-3+2)x-6\\=x^2-3x+2x-6\\=x(x-3)+2(x-3)\\=(x+2)(x-3)\\\Rightarrow y=(x+2)(x-3)\)

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

Let the price of the paint be = $ 36.92

Let the price of the building blocks be = $ 51.86

So , the total price of the purchase = price of the paint + price of the building blocks

Substituting the values in the equation , we get

The total price of the purchase = 36.92 + 51.86

The total price of the purchase = $ 88.78

Now , the total amount Glitter gave = $ 100

So ,

The amount balance Glitter receives A = total amount Glitter gave - total price of the purchase

Substituting the values in the equation , we get

The amount balance Glitter receives A = 100 - 88.78

The amount balance Glitter receives A = $ 11.22

Therefore,  the value of A is $ 11.22

Hence , the amount balance Glitter receives is $ 11.22

To ensure that there is an equal number of glass bears in each group, Mrs. Dryson constructed a total of 17 groups, which can be calculated using arithmetic operations.

What is arithmetic operations?

The study and application of numbers in all other fields of mathematics are covered in the area of mathematics known as arithmetic operations. Addition, subtraction, multiplication, and division are included in the basic operations.

As given in the question,

Mrs. Dryson divided her collection of 52 glass bears into equal groups and She had one bear left over

The steps listed below can be used to calculate the total amount of Mrs. Dryson's products:

Step 1: Arithmetic operations can be utilized to calculate Mrs. Dryson's overall output.

Step 2: Keep in mind that there are 52 glass bears in all, and after separating them into equal groups, she was left with just one bear.

Step 3 - The total bear population to divide into groups of an equal number is calculated as follows:

= 52 - 1 = 51

Step 4: The number that is divided by 51 such that the result is an integer is 3.

Step 5 - As a result, Mrs. Dryson created a total of the following groups:

= 51/3 = 17.
