The closure property is defined below.

According to Closure Property, the set of numbers on which the mathematical operation like addition, subtraction, and multiplication are performed the result will be the number of the same set.

An example of this is if addition is done on two whole numbers the output will be a whole number.

The closure Property is valid for Whole numbers, Natural Numbers, Rational Numbers, Real Numbers, and Integers

For Natural Numbers: Addition of a + b = N

(a, b and N = natural numbers)

The expression which shows the amount of money, in dollars Maddie spent on mailing letters in March is 3.7 +0.74 y.

Given Maddie mailed y letters in January. She mailed 3 times as many letters in February. In March she mailed 10 letters more than half of what she mailed in January and February.

Expression  is combination of numbers, symbols, fraction, coefficients which are not found in equal to form.

Letters mailed in January=y

Letters mailed in February=3y

Letters mailed in March=10+(y+3y)/2

=10+2y

Amount of mailing of 1 letter=$0.37.

Amount of mailing of letters in March=0.37(10+2y)

=3.7+0.37*2y

There are 3 tolls where Stephanie pays $ 4.05.

The distance between two points is the length of the path connecting them.

Here,

Distance covered by Stephanie = 12 1/4 miles

                                                     = 12.25 miles

Distance between two toll tax = 3 1/2 miles

                                                   = 3.5 miles

Number of Tolls = Total distance covered / Distance between two tolls

                            = 12.25 / 3.5

                            = 3.5

                            ≈ 3 tolls.

Cost of 1 toll = $ 1.35

Total amount paid on toll = 3 X 1.35

Answer:

Step-by-step explanation:

In a 45-45-90 right triangle, the hypotenuse is sqrt(2) times the length of the leg.

Answer:

P = $900

Step-by-step explanation:

Simple Interest Formula: [tex]A = P(1+rt)[/tex]

Where A is the final amount,

P = Principal

r = Interest Rate in Percent or [tex]\frac{r}{100}[/tex] per annum

t = time in years

From the information given in the question,

A = $918

r = 2% per annum or [tex]\frac{2}{100}[/tex]

t = 1 year

Lets substitute these values to find P, the principal.

[tex]P(1+(\frac{2}{100} )(1))=918\\P(1+0.02)=918\\1.02P=918\\P = \frac{918}{1.02} \\=$900[/tex]

Therefore, P = $900

The relative frequency for cat is 0.35.

The relative frequency for bird is 0.15.

The relative frequency for fish is 0.1

The ratio of the total number of events occurring in a scenario to the number of times an event occurs is known as relative frequency.

Relative Frequency = Subgroup frequency/ Total frequency.

n = subgroup frequency

Calculation for the relative frequencies of the pet types:

(1) Relative frequency for dog:

Total frequency is 20.

The frequency for dog is 8.

Relative frequency for dog =  frequency for dog/total frequency

                                             = 8/20

The algebraic expression for "m decreased by 47%" is m - 0.47m.

To translate "m decreased by 47%" into an algebraic expression, we first need to understand the meaning of the phrase. "Decreased by" indicates a subtraction operation, and "47%" represents 47 percent, which is equal to 0.47 in decimal form.

Let's break down the expression step by step:

"m" represents the original quantity we want to find.

"Decreased by" indicates subtraction.

"47%" is equivalent to multiplying the original value "m" by 0.47.

Combining all these elements, the algebraic expression for "m decreased by 47%" is:

Answer:

9/28 and 32.1%

Step-by-step explanation:

So the sample space consists of all products for (5 * 1, 5 * 2, 5 * 3.... and the same thing for 6, 7, and 8)

This gives you the sample space: {5, 10, 15, 20, 25, 30, 6, 12, 18, 24, 30, 36, 7, 14, 21, 28, 35, 42, 8, 16, 24, 32, 40, 48}.

The size of the sample space is 4 * 6, since for each number (5, 6, 7, 8), there are 6 products (the dice have six numbers). This means the sample space has 24 combinations, you can also verify this by manually counting the sample space.

Now filtering the sample space so you only get a product that is 28 or higher you get: {30, 30, 36, 28, 35, 42, 32, 40, 48} which has 9 possible combinations that have a product greater than or equal to 28. Divide this by the entire sample space and you get a probability of: 9/28, which in decimal form is approximately: [tex]0.3214[/tex]. Multiplying this by 100 gives you: [tex]32.1[/tex]%

Answer: [tex]128^{\circ}[/tex]

Step-by-step explanation:

By the inscribed angle theorem, minor arc EG measures 92 degrees.

Since the circumference of a circle measures 360 degrees, arc EF measures [tex]360-140-92=128^{\circ}[/tex]

The measure of the arc EF = 128°.

Arc is that part of the circumference of the circle which is formed by two points on the circle.

The angle subtended by an arc on the center of the circle is twice that it subtends on the circumference of the circle.

So,

The measure of arc EG = 2 * 46 = 92

The measure of arc GF = 140°

The complete circle has an angle of 360° at the center

The measure of the arc EF = 360 -mEG - mGF

The measure of the arc EF = 360 - 92 -140

The measure of the arc EF = 128°.

Therefore, The measure of the arc EF = 128°.

  (a)  The number of positive zeros is either 2 or 0. The number of negative zeros is either 2 or 0.

Step-by-step explanation:

The possible numbers of real zeros can be found using Descarte's Rule of Signs.

When signs of coefficients of terms of the polynomial are listed in order of decreasing degree, the number of sign changes can be counted. That number is the number of possible positive real zeros of the polynomial.

When the signs of odd-degree terms are changed, the number of sign changes becomes the possible number of negative real zeros.

The actual number of real zeros may be less by a multiple of 2. (The zeros may be complex, and complex zeros come in pairs.)

The signs of the terms in the given polynomial are ...

  + - + + + . . . . . 2 sign changes: 2 or 0 positive real zeros

When the signs of odd-degree terms are changed, they become ...

  + + + - + . . . . . 2 sign changes: 2 or 0 negative real zeros

Descarte's rule of signs lets us conclude ...

The number of feet in the length of the handrail is 17.3 ft.

The easiest way to see this is to imagine that we can "unfold" the spiral to create a rectangle

The bottom side of the rectangle is just the arc length of a circle with a radius of 3 ft  turned through 270°= (3/4) of a whole revolution

(3/4) (2pi) (3)  =  (9/2)pi ft =   4.5 pi ft

The side of the rectangle will be the rise of the staircase = 10ft

And the diagonal of the rectangle will be the length of the handrail

We can use the Pythagorean Theorem to solve this

Handrail length = √ [ (4.5 pi)^2 + 10^2 ]  ≈  17.3 ft
