If there were 18 students in each group and they were asked to form six equal groups, then there would be a total of 108 students.

i.e. (18 students x 6 groups = 108 students)

When a group of students are asked to form a certain number of equal groups, the total number of students can be determined by multiplying the number of students in each group by the number of groups.

In this case, the students were asked to form six equal groups and there were 18 students in each group.

To find the total number of students, we simply multiply 18 by 6.

Therefore, there were 108 students in total.

This is because when you have x number of groups and y number of students in each group, the total number of students is xy.

In this case x=6 and y=18, so the total number of students is 6*18 = 108.

Answer:

A

Step-by-step explanation:

Angle A=Angle X

AB=XY

AC=XL

Given that the polynomial is 12xy - 9x - 8y + 6, we must determine its fully factored form.

There are two variables in the given polynomial.

12xy - 9x - 8y - 6 = 3x(4y - 3) Now, 12xy - 9x - 8y - 6 = 3x(4y - 3) - 2(4y - 3) = (3x - 2)(4y - 3) The polynomial's fully factored form is (3x - 2)(4y - 3)

(3x - 2)(4y - 3) is the fully factored form of 12xy - 9x - 8y + 6.

One approach to factoring expressions is factoring by grouping. If the expression can be broken down into its component parts, this approach is helpful. On the other hand, we can employ additional strategies.

A polynomial is an expression made up of variables, constants, and exponents that are added, subtracted, multiplied, and divided using mathematical operations (no division by a variable).

Test score of a student who does not study for the test 70%.

A figure or ratio that may be stated as a fraction of 100 is a percentage. If we need to calculate a percentage of a number, we should divide it by its entirety and then multiply it by 100.

The proportion therefore refers to a component per hundred. Per 100 is what the word percent means. The sign "%" is used to denote it.

Out of a hundred is what the word "percent" refers to. Percentages are used in mathematics to represent subsets of a whole, just like fractions and decimals are. The whole is thought of as being composed of 100 equal parts when using percentages. As a less common alternative, the abbreviation "pct" may be used to indicate that a number is a percentage.

No, the number 52 is not a perfect square. Because the square root of 52 is an irrational number.

An irrational number is a real number that cannot be expressed as a ratio of two integers, or in other words, as a fraction. Irrational numbers include numbers such as pi (π), the square root of 2, and the square root of 3, which are not terminating or repeating decimals. They cannot be written as a finite decimal or a fraction of integers. Irrational numbers have an infinite number of decimal places, which means they cannot be represented exactly as a decimal.

They are also non-repeating and non-terminating decimals. Irrational numbers have many important properties and applications in mathematics, such as in geometry, where they are used to calculate the lengths of curves and the areas of circles. They also appear in trigonometry and calculus. Irrational numbers are also important in physics and engineering as well as other branches of science and technology.

The degree of the polynomial p(x) = 3x²y³ - 4xy⁴ + x⁶ + y⁵ is 6.

A degree of a polynomial is the highest power of the variable in the polynomial. For example, in the polynomial 2x^3 + 4x^2 - 5x + 7, the degree is 3 (the highest power of x is x^3). A polynomial of degree 0 is a constant polynomial and a polynomial of degree 1 is a linear polynomial.

To find the degree of a polynomial, you can do the following:

→ Write the polynomial in standard form, with the terms arranged in descending order of exponents.

→ Take the exponent of the term with the highest exponent. This exponent is the degree of the polynomial.

Given,

p(x) = 3x²y³ - 4xy⁴ + x⁶ + y⁵

angle RQS = 101 degrees

angle TQS = 79 degrees

===================================================

Explanation:

A straight angle has a measure of 180 degrees. It's another way of saying "straight line".

The two angles shown add to 180.

We'll use this fact to solve for x.

(angleRQS) + (angleTQS) = angle RQT

(9x+2) + (7x+2) = 180

16x+4 = 180

16x = 180-4

16x = 176

x = 176/16

x = 11

Use this x value to determine the angles we're after.

Check:

(angleRQS) + (angleTQS) = 101+79 = 180 which confirms the answer is correct.

The number of atoms that can be laid end-to-end on a meter stick is equivalent to 10^8 atoms.

A meter is equivalent to 100 centimeters (cm), and an atom is about 10^-8 centimeters in length. So, when we divide the length of a meter stick (100 cm) by the length of one atom (10^-8 cm).

we are essentially dividing 100 by a decimal number on the order of 0.00000001.

This is the same as multiplying 100 by a number on the order of 100,000,000. In other words, we are multiplying 100 by 10^8.

So, 100 cm / (1*10^-8 cm) = 10^8 atoms

This means that the number of atoms that can be laid end-to-end on a meter stick is equivalent to 10^8 atoms which is a very big number, this is why we use scientific notation to represent it.

X = 20

Step-by-step explanation:

The two quadrilaterals are similar to each other. So the ratio of  each side of the larger quadrilateral to the corresponding side of the smaller quadrilateral must be the same.

Examining the two figures we see the side which has  68° and 128° pf the smaller quadrilateral has length 2

The corresponding side of the larger quadrilateral on the right is 6

So each side of the larger quadrilateral =6/2 = 3 times each side of the smaller one

Side which has length 10 pf the smaller quadrilateral corresponds to the side with length x+10 of the larger one. This ratio must also be 1:3

So

[tex]\dfrac{10 + x}{10}= 3\\\\[/tex]

Cross-multiplying we get
10 + x = 10 x 3

10 + x = 30

x = 30-10

The value L that a function f(x) approaches when its input value x approaches a predetermined value c is referred to as the function's limit.

The limit of f(x) as x approaches c does not exist if, at the value c, there is no single value L that the function f(x) can be considered to approach.

The behavior of the function as it approaches c from both the right and the left must be examined in order to ascertain whether this is true of the function (that is, from x values that are larger and smaller than c, respectively).

A fundamental idea in calculus is the concept of limits. Limits help one to comprehend the connection that a function creates between its variables.

On that particular night, there were 144 student tickets and 432 non-student tickets sold.

Let x be the number of student tickets sold that night

y be the number of non-student tickets sold that night

On that night, there were three times as many student as there were non-students. Hence, we can write that as an algebraic expression such that

3x = y

If tickets cost $5 for students and $9 for non-students, and on that night, they sold $4,608 in tickets, then we can express that as

$5x + $9y = $4608

5x + 9y = 4608

Substitute the value of y from the first expression to the second and solve for x.

5x + 9y = 4608

5x + 9(3x) = 4608

5x + 27x = 4608

32x = 4608

x = 144

Plug in the value of x into the first expression and solve for y.

y = 3x

Answer: 2:7

Step-by-step explanation:

Vanilla icecream = 4

Chocolate icecream = 14

4:14=2:7

2X2=4

7X2=14

Step-by-step explanation:

a ratio is simply relating 2 (or more) groups and their sizes.

in our case here the ratio is

4/14 = 2/7

this is often written as

4:14 = 2:7

it means that for every 2 people liking (I assume "preferring") vanilla ice cream there are 7 people liking (preferring) chocolate ice cream.

FYI

in total, a ratio also tells us about the size of the sample for the observation or analysis. 4/14 tells us there are 18 (4+14) people in the survey. and the simplified form 2/7 tells us that we can split the whole survey group into units of 9 (2+7) people with the same behavior as the total group.

a ratio is a fraction (incl. all the calculation and comparison rules) with a special meaning.

so, don't mix the ratio up with e.g. the fractions of the different behaviors in the group :

4/18 = 2/9 of the whole group prefer vanilla.

14/18 = 7/9 of the whole group prefer chocolate.

the ratio is now the relative size relationship between both : 2/9 / 7/9 = 2/7

Answer:This is a mathematical expression. To solve it, we can use the order of operations (PEMDAS)

First, we simplify the expressions inside the parentheses.

5+7 = 12

Then, we simplify the multiplication

12 * 200 = 2400

So the result of (5+7)*200 is 2400.

Answer:

(0, 3 )

Step-by-step explanation:

y = 2x + 3 → (1)

3x + 2y = 6 → (2)

substitute y = 2x + 3 into (2)

3x + 2(2x + 3) = 6 ← distribute parenthesis and simplify left side

3x + 4x + 6 = 6

7x + 6 = 6 ( subtract 6 from both sides )

7x = 0 , then

x = 0

substitute x = 0 into (1) for y

y = 2(0) + 3 = 0 + 3 = 3

solution is (0, 3 )

To solve for g in terms of T, L, we can manipulate the formula T = 2π √(L/g) as follows:

First, we divide both sides by 2π:

T/2π = √(L/g)

Then, we square both sides:

(T/2π)² = (L/g)

Then, we multiply both sides by g^2 :

(T^2/4π^2) = L

Finally, we divide both sides by L:

(T^2/4π^2 * L) = g

So the formula for g in terms of T, L is g = (T^2/4π^2 * L)
