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 ,

The number of planes that land every 8 minutes = 4 planes

The number of planes that land every minute =
The number of planes that land every 8 minutes / 8

The number of planes that land every minute = ( 4 / 8 ) planes

                                                                            = 1/2 plane

Now ,

1 hour = 60 minutes

The number of planes that land every hour =
The number of planes that land every minute x 60

The number of planes that land every hour = ( 1/2 ) x 60

                                                                        = 30 planes

Hence , the number of airplanes that land every hour is 30 airplanes

Answer:  option 2 describes best

Step-by-step explanation:Given Marisol grouped the terms and factored the GCF out of the groups of the polynomial 6x3 – 22x2 – 9x + 33. Her work is shown.  

Step 1: (6x3 – 22x2) – (9x + 33)

Step 2: 2x2(3x – 11) – 3(3x + 11)

Marisol noticed that she does not have a common factor. Which accurately describes what Marisol should do next?

Marisol should realize that her work shows that the polynomial is prime.

Marisol should go back and group the terms in Step 1 as (6x3 – 22x2) – (9x – 33).

Marisol should go back and group the terms in Step 1 as (6x3 – 22x2) + (9x – 33).

Marisol should refactor the expression in Step 2 as 2x2(3x + 11) – 3(3x + 11).

According to question Marisol grouped the terms and has done factorisation of the given polynomial 6x^3 – 22x^2 – 9x + 33.

In step 1 she has written as (6x^3 – 22x^2) – (9x + 33)

Marisol has to go to step 1 in order to correct her mistake. She has to group the expression as (6x^3 – 22x^2) – (9x – 33) so that she will be able to get the expression as

6x^3 – 22x^2 – 9x + 33 after opening the brackets.

The accurately describes what Marisol should do next will be;

⇒ Marisol should go back and group the terms in Step 1,

as (6x³ - 22x²) - (9x - 33)

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

Marisol noticed that she does not have a common factor.

And,  Her work is shown.

Step 1: (6x³ -  22x²) - (9x + 33)

Step 2: 2x²(3x – 11) - 3(3x + 11)

Now,

Since, The polynomial is,

⇒ 6x³ - 22x² - 9x + 33

And, Her work is shown.

Step 1: (6x³ -  22x²) - (9x + 33)

Step 2: 2x²(3x – 11) - 3(3x + 11)

Clearly, She make mistake on step 1 as to take negative sign common.

Hence, The accurately describes what Marisol should do next is;

⇒ Marisol should go back and group the terms in Step 1,

as (6x³ - 22x²) - (9x - 33)

Answer: a. machine learning, use of statistical methods, large amounts of data

Step-by-step explanation: Deriving patterns, insights and information which aren't visible from raw information or data could be done through the data mining process. Data mining is performed through a combination of statistical methods and machine learning applied on large amount of dataset, machine learning affords systems the ability to learn on their own without hardcoding or explicitly programmed with statistical methods being a core part of the algorithm used to drive the process of making accurate prediction.

Steps to solve:

(12x + 4) - 8 = 12

~Combine like terms

12x - 4 = 12

~Add 4 to both sides

12x = 16

~Divide 12 to both sides

x = 16/12 or x = 4/3

Answer:

9 meters

Step-by-step explanation:

189 divided by 21 is 9 (:

Answer:

9m

Step-by-step explanation:

To find the width of a rectangle given area and length all you need to do is take your area (189 in this case) and divide it by your length. (In this case 21.)

Here's our equation:

189 ÷ 21 = 9

(remember the meters squared is important if you're finding area. This doesn't apply in our case as we're only finding the width. To be more clear the "m² and/or m^2")

9m is your answer.

Hope this helps and have a nice day!

Answer:   y= 64  

Step-by-step explanation:

If y is 16 when  x is 2  This means if  x is 8 y will be 64.

Set up the proportional equation

[tex]\frac{2}{16} = \frac{8}{y}[/tex]     Cross multiply  

2y = 128

y= 64

The value of y when x=8 is 256.

It is given that

y ∝ x²

So, y = kx²....(1)

where k = constant of proportionality

It relates two parameters that are mutually dependent.

It is given that

When, x=2, y=16

This means, (1) becomes, 16=k.2² ⇒k =4

So, (1) becomes, y =4x²

So, when x= 8, y= 4*8²

So, y =256 when x=8

Therefore, The value of y when x=8 is 256.

Answer:

In fraction form: 1/25

In percent: 4%

Step-by-step explanation:

Answer: The musical group sold  60%of the white hats and  70%of the black hats.

A greater percentage of  black hats were sold.

Step-by-step explanation: to answer this question we have to divide the number of hats sold by the number of total hats for each case.

Then, we have to multiply that result by 100, to obtain the result in percentage form.

White Hats: (120/200) x 100 =60%

Black hats: (210/300) x 100= 70%

The musical group sold 60%of the white hats and 70%of the black hats.  

A greater percentage of black hats were sold. (Since 70 > 60 )
