Answer:

294 - 150 divided by 8 = A

Step-by-step explanation:

So, we already know, that we have $294 as our total. If we subtract $150, we get $144. The final step would be to divide it by $8 and that would be 18. There is 18 guests at the party.

The length of AC and AB is 19 and 11.

It is the measurement of something from end to end or along its longest side or a measurement of a particular part of something:

We have,

BC = 8

AC = 3x - 8

AB = 2x - 7

We can  make the line as:

A______B______C

We can write as:

AC = AB + BC

3x - 8 = 2x - 7 + 8

Simplify all the like terms together.

3x - 2x = 8 - 7 + 8

x = 16 - 7

x = 9

Now,

AC = 3x - 8 = 3 x 9 - 8 = 27 - 8 = 19

AB = 2x - 7 = 2 x 9 - 7 = 18 - 7 = 11

Thus the length of AC and AB is 19 and 11.

The equation of the (g • h)(n) is (g • h)(n) = -4n³ - 8n² - 24n - 20 if the g(n)=-4n- 4 and h(n)=n² +5+n.

It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.

It is given that:

g(n) = -4n - 4

h(n) =  n² +5+n

(g • h)(n) = g(n)h(n)

= (-4n - 4)(n² +5+n)

= -(4n + 4)(n² +5+n)

After simplification:

(g • h)(n) = -4n³ - 8n² - 24n - 20

Thus, the equation of the (g • h)(n) is (g • h)(n) = -4n³ - 8n² - 24n - 20 if the g(n)=-4n- 4 and h(n)=n² +5+n.

The maximum number of people who can go to the amusement park is 7 based on tickets cost of $20.50 per person

What is the total cost function for the amusement park?

The total cost is made up of cost of admission and parking and the tickets cost per person, which means that the total cost can be modeled as shown below based on the fact the number of persons that can attend is x

total cost=6.25+20.50x

total cost=155

155=6.25+20.50x

answer is  y ≤ [tex]\frac{1}{3}x (-4)[/tex]

Given that,

Area of shaded inequality below solid line is positive

and  y-intercept of the solid line is equal to  - 4

therefore,

The inequality must be

y ≤ [tex]\frac{1}{3}x (-4)[/tex]

In Mathematics, inequality represents the mathematical expression in which both sides are not equal. If the relationship makes the non-equal comparison between two expressions or two numbers, then it is known as inequality in Maths. In this case, the equal sign “=” in the expression is replaced by any of the inequality symbols such as greater than symbol (>), less than symbol (<), greater than or equal to symbol (≥), less than or equal to symbol (≤) or not equal to symbol (≠). The different types of inequalities in Maths are polynomial inequality, rational inequality, absolute value inequality.

A system of linear inequalities in two variables includes at least two linear inequalities in the identical variables. When we solve linear inequality then we get an ordered pair. So basically, in a system, the solution to all inequalities and the graph of the linear inequality is the graph displaying all solutions of the system. Let us see an example to understand it.

the Linear inequality: 2x – y >1, x – 2y < – 1

The symbols ‘<‘ and ‘>’ express the strict inequalities and the symbols ‘≤’ and ‘≥’ denote slack inequalities. A linear inequality seems exactly like a linear equation but there is a change in the symbol that relates two expressions.

here is given step to easily find the value of inequality:

Step 1: The inequality is already in the form that we want. That is, the variable y y is isolated on the left side of the inequality.

Step 2: Change inequality to equality. Therefore, y > x + 1y>x+1 becomes y = x + 1y=x+1.

Step 3: Now graph the y = x + 1y=x+1. Use the method that you prefer when graphing a line. In addition, since the original inequality is strictly greater than symbol, \Large{>}>, we will graph the boundary line as a dotted line.

Step 4: The original inequality is y > x + 1y>x+1. The greater than symbol implies that we are going to shade the top area or region.

Answer: C

Step-by-step explanation:

Answer: C is the correct answer

Step-by-step explanation:

Answer: The first one is 15 and the second one is 1.

Step-by-step explanation: I plugged in -4 where x is so the equation was (-4)^2-1 which equals 15.For other one i did the same thing except with the 2 so the equation was 3(2)-5 which equals 1.

[tex]range = 119.1 - 78 .4 = 40.7[/tex]

First determine the mean average:

[tex]mean = \frac{119.1 + 95.2 + ... + 90.1}{10} = 99.76[/tex]

[tex]stdev = \sqrt{ \frac{ \sum(x - mean) {}^{2} }{n - 1} } = \sqrt{ \frac{(119.1 - 99.76) {}^{2} + ... }{10 - 1} } = 15.285[/tex]

Applying the linear pair postulate:

y = 30

m<ACB = 160°

According to the linear pair postulate, the sum of two adjacent angles that form a linear pair is equal to 180 degrees.

Given the following:

m<ACB = (4y + 40)°

m<DCE = (y - 10)°

Angles ACB and DCE are a linear pair. Therefore:

m<ACB + m<DCE = 180°

Substitute

(4y + 40) + (y - 10) = 180

Solve for y

4y + 40 + y - 10 = 180

Combine like terms

5y + 30 = 180

Subtract 30 from both sides

5y + 30 - 30 = 180 - 30

5y = 150

Divide both sides by 5

5y/5 = 150/5

y = 30

Find m<ACB:

m<ACB = (4y + 40)°

Plug in the value of y

m<ACB = 4(30) + 40

m<ACB = 120 + 40

m<ACB = 160°

Thus, applying the linear pair postulate:

y = 30

m<ACB = 160°

There are 40128 peoples in the parade route by proportion.

According to the given question.

You can fit 19 people in a 5ft x 5ft square.

Here we need to find the number of peoples in the 10ft x 1 mile parade.

Since, we have to convert miles into feet then,

1 mile = 5280 feet

We know that the parade route is in the form of rectangle.

Also, the process of proportion reasoning involves understanding the multiplicative relationships between rational quantities.

Now we will find the number of peoples by proportions,

Let us consider the number of people in the rectangle as x.

Therefore,

19/25  = x/5280

⇒ (19/25)(5280) = x

⇒ x = 40128

The simplified form of (2 + i)/(2 - i) is (3 + 4i)/5

A Simple Form or simplified form can be defined as When a fraction's numerator and denominator share only one common factor, it is said to be in its simplest form.

Consider the given complex number(2 + i)/(2 - i)

Multiply both numerator and denominator with the complex number (2 + i), and we get

{(2 + i) × (2 + i)} / {(2 + i) × (2 - i)}= {(2 + i) × (2 + i)} / (2² - i²)          

(using the formula (x + y)(x - y) = x² - y²)= {(2 + i) × (2 + i)} / (4 - (-1))= {(2 + i) × (2 + i)} / (4 + 1)= {(2 + i) × (2 + i)} / 5= (2² + 2i + 2i + i²)/5= (4 + 4i + (-1))/5= (3 + 4i)/5

The original price of the helmet is 300.

In mathematics, a percent is a number or ratio expressed as a fraction of 100. It is often denoted using percentage sign "%".

Now it is given that,

Price of helmet = 195

Discount on helmet = 35% = 0.35

Let the original price be x.

Now since Price of helmet = 195

Thus, Original price = x - 0.35x = 0.65x

Hence we get

0.65x = 195

Dividing both the side by 0.65 we get

x = 195/0.65

Solving we get

x = 300

this is the required original price of the helmet.

Thus, the original price of the helmet is 300.
