simplify the expression 8 + (7 + x)

Step-by-step explanation:

Divide, the same as ÷

divide 6 by 3

by is the same as the symbol

6 ÷ 3 = 2

Difference, This is another way of saying take away or minus

the difference of 6 and 3 is

6 - 3 = 3

Product, This is another word for multiply or times

the product of 2 and 3 is

2 × 3 = 6

divide (÷)  the difference of 20 and 6 (20 - 6) by the product of 7 and 2       (7 × 2)

so

(20 - 6) ÷ (7 × 2)

can you do the rest???

Answer:

6666

Step-by-step explanation:

Answer:

87.9646 millimeters.

Step-by-step explanation:

The circumference (C) of a circle is given by the formula:

C = πd

Where d is the diameter of the circle and π (pi) is a mathematical constant approximately equal to: 3.14159.

In this case, the diameter of the circle is given as 28 millimeters, so we can substitute this value into the formula to find the circumference:

C = πd = π(28 mm) = 87.9646 mm (rounded to 4 decimal places)

Therefore, the circumference of the circle is approximately 87.9646 millimeters.

Answer:

y + x > -2

Step-by-step explanation:

slope is negative and is -1

y-intercept is -2

equation of dashed line is y = -x - 2

shading is above the line, and line is dashed, so inequality is

y > -x - 2

Add x to both sides.

y + x > -2

Lowest price of an iPhone in Paris is €800 because they stated that one euro is equal to one dollar; when multiplied, the result is 944; this indicates that the iPhone is priced lower in Paris.

It is possible to compare the conversion rates of sterling into the euro and the dollar using the same amount of pounds.

Sterling to Euro : \($750 \times 1.14=6855$\)

Pounds to dollars : \($750 \times 1.39=\$ 1042.5$\)

One phone may be purchased with one pound. The dollar is insufficient to purchase a cell phone, but the euro has enough money to do so. Paris has the lowest pricing for the iPhone from this perspective.

The iPhone SE (2020), which costs Rs 40,000, costs more over a lakh rupees according to the most recent Apple price list for India. Everywhere in the globe, the USA market offers the cheapest prices for iPhones.

The solution is, sinФ = √45/7 & cotФ =2/√45.

Trigonometry is a branch of mathematics that studies relationships between side lengths and angles of triangles.

here, we have,

secФ = 7/2

so, cosФ = 2/7

cos^2Ф = 4/49

i.e. sin^2Ф = 1- cos^2Ф

                  = 1 - 4/49

                  = 45/49

so, sinФ = √45/7

now, we know,

cotФ = cosФ/sinФ

        = 2/√45

According to census the total number of male and female was 88,51,84,692, if number of male was 45,40,34,570 the number of female population is 43,11,50,122.

To find the wide variety of girl population, we will subtract the quantity of male population from the full population.

Total population = 88,51,84,692

Number of male = 45,40,34,570

Number of female = Total population - Number of male

= 88,51,84,692 - 45,40,34,570

= 43,11,50,122

Therefore, the number of female population is 43,11,50,122.

Answer:

$0.33 per cookie

Step-by-step explanation:

The unit rate (cost per cookie) is

     $4

---------------- = $0.33 per cookie

12 cookies

Answer:

Roughly $0.34

Step-by-step explanation:

Set up an equation:

Variable x = cost of one cookie

12cookies/$4 = 1cookie/x

12/4 = 1/x

Cross multiply

12 × x = 4 × 1

12x = 4

Divide both sides by 12

12x ÷ 12 = 4 ÷ 12

1x = 4/12

x = 0.333333

x = is about $0.34

On solving the query we can say that The slant height, along with the function cone's height and radius, makes a right triangle as it measures from the apex to a certain point on the circular base.

Mathematics is concerned with numbers and their variations, equations and related structures, shapes and their places, and possible placements for them. The relationship between a collection of inputs, each of which has an associated output, is referred to as a "function". An relationship between inputs and outputs, where each input yields a single, distinct output, is called a function. Each function has a domain and a codomain, often known as a scope. The letter f is frequently used to represent functions (x). X is the input. The four main types of functions that are offered are on functions, one-to-one functions, many-to-one functions, within functions, and on functions.

You are informed that the cone in this scenario has a volume of 4.5 cubic inches. Using the aforementioned calculation, you can determine the radius if you know the cone's height.

Alternately, you may use the Pythagorean theorem to calculate for the radius if you know the cone's slant height. The slant height, along with the cone's height and radius, makes a right triangle as it measures from the apex to a certain point on the circular base.

Part A :

Yes, the statement is true that  P( A and B ) = 0 .

Given,

Event A and Event B are mutually exclusive.

Thus P ( A and B ) = 0

Part B:

A and B are mutually exclusive events if they do not occur at the same time.

This means that A and B do not share any common outcomes and

P(A and B) = 0.

Part C:

Let,

The sample space W = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10}.

Let A = {1, 2, 3, 4, 5}, Y = {4, 5, 6, 7, 8}, and B = {7, 9}.

A and B do not have any numbers in common so P(A and B) = 0.

Note that the size of angle x = 115°. This is a problem relating to the sum of angles in a circle. See the computation below.

The sum of angles in a circle is always equal to 360 degrees or 2π radians.

This means that the sum of the measures of the angles formed by any number of rays or line segments that meet at a common point, or vertex, and whose endpoints lie on the circle, will always add up to 360 degrees or 2π radians. This property is often used in geometry and trigonometry to solve problems involving circles and angles.

With regard to the above problem,

We are given three angles in a circle named as follows:

a) 81°

b) 164°

c) x

The above rule state that

81 + 164 + x = 360°

thus, x = 360 - 81 - 164

x = 360 -245

x = 115°

Answer: 3x^4+7x^3+7x^2+11x+4

Step-by-step explanation:

(x^2+3x+4)(3x^2-2x+1)

3x^4-2x^3+x^2+9x^3-6x^2+3x+12x^2-8x+4

Collect like terms

3x^4-2x^3+9x^3+x^2-6x^2+12x^2+3x+8x+4

3x^4+7x^3+7x^2+11x+4

Answer:

To multiply (x^2 + 3x + 4) and (3x^2 - 2x + 1), we need to distribute each term of the first polynomial to every term in the second polynomial:

(x^2 + 3x + 4)(3x^2 - 2x + 1)

= x^2 * (3x^2 - 2x + 1) + 3x * (3x^2 - 2x + 1) + 4 * (3x^2 - 2x + 1)

Now, let's simplify each term:

= 3x^4 - 2x^3 + x^2 + 9x^3 - 6x^2 + 3x + 12x^2 - 8x + 4

Combining like terms:

= 3x^4 + (-2x^3 + 9x^3) + (x^2 - 6x^2 + 12x^2) + (3x - 8x) + 4

= 3x^4 + 7x^3 + 7x^2 - 5x + 4

So, the product of (x^2 + 3x + 4) and (3x^2 - 2x + 1) is 3x^4 + 7x^3 + 7x^2 - 5x + 4.

Therefore, the correct answer is option C: 3x^4 + 7x^3 + 7x^2 - 5x + 4.

Answer:

4x^4+39x+30/3x

Step-by-step explanation:

The length of AC = 3.55.

In the given triangle,

AB = 20 m = c

BC = 31 m = b

AC = a = ?

∠A = 95 degree

We know the cosine rule,

CosA = (b² + c² - a²)/2bc

Therefore,

⇒  Cos95 = (31² + 20² - a²)/(2x31x20)

⇒  -0.087 = (1361 - a²)/1240

⇒ -107.88 = (1361 - a²)

⇒          a² = 12.62

⇒          a  = 3.55

AC = 3.55.

Answer:

D. erosion

Step-by-step explanation:

The wind is a stronger erosional force in arid regions than it is in humid regions because winds are stronger. In humid areas, water and vegetation bind the soil so it is harder to pick up. In arid regions, small particles are selectively picked up and transported. As they are removed, the ground surface gets lower and rockier, causing deflation. What is left is desert pavement, a surface covered by gravel-sized particles that are not easily moved by wind.
