The residents of a city voted on whether to raise property taxes. The ratio of yes votes to no votes was 7 to 4 . If there were 8657 total votes, how many yes votes were there?

The requried ratio of boys in the club to girls is given as 7/9 or 7:9. Option A is correct.

The ratio can be defined as the proportion of the fraction of one quantity towards others. e.g.- water in milk.

Here,
The conservation club has 32 members. There are 18 girls in the club.
Number of boys = 32 - 18 = 14
Ratio of boys to girls = number of boys / number of girls
                                = 14 / 18 = 7/9

Thus, the requried ratio of boys in the club to girls is given as 7/9 or 7:9. Option A is correct.

The proof of the given question is given in the solution as follows

A technique for factoring a number or a polynomial is called factorisation. The polynomials are divided into the sums of their component parts. As an illustration, x2 + 2x may be factored as x(x + 2), where x and x+2 are the factors that can be multiplied to obtain the original polynomial.

The six types of factoring are: greatest common factor, difference in two squares, grouping, sum or difference in two cubes, trinomials, and general trinomials.

In the given equation

we separate m2-1/n2 to (a+b)(a-b) form

and hence we get the answer as

For solving the equation we are using

The definition of an equation in algebra is a mathematical statement that demonstrates the equality of two mathematical expressions. For instance, the equation 3x + 5 = 14 consists of the two equations 3x + 5 and 14, which are separated by the 'equal' sign.

A mathematical statement that has a "equal to" symbol between two expressions with equal values is called an equation. as in 3x + 5 Equals 15, for instance. Equations come in a variety of forms, including linear, quadratic, cubic, and others. In this tutorial, let's study more about math equations.

The equation is 2x = 13 - 5

The equation to find the number of leaves which Aidan has now, n is given by 8 × 12 - 7 = n.

In Mathematics, an equation can be defined as a mathematical expression which shows that two (2) or more thing are equal.

Next, we would write the equation that gives n, the number of leaves Aidan would have after collecting leaves for an art project as follows:

The number of leaves that Aidan collected from 8 different trees is equal to 8 leaves. Additionally, Aidan picks 12 leaves from each tree to have a total of 96;

n = 8 × 12 = 96.

Lastly, Aidan lost 7 leaves on his way home. Therefore, we would subtract 7 leaves from the total number of leaves that Aidan collected from 8 different trees;

n = 96 - 7 = 89 leaves.

In conclusion, the complete equation is represented by 8 × 12 - 7 = n.

Mary and Jane have multiple ways to choose their subset of figurines for the comic book convention.

We know that Mary must include every figurine that Jane brings, so Mary must choose a subset of her collection that is at least x+1 figurines.

Since Mary must also choose at least one additional figurine, the total number of figurines that Mary can choose from is n-(x+1) + 1 = n-x

The total number of ways that Mary and Jane can choose their subsets is the product of the number of ways each can choose their subsets.

So, the number of ways is

(choose x out of n) * (choose x+1 out of n)

This is also known as binomial coefficient, which can be represented as nCx or (n x)

Hence the number of ways is

The volume of the baseball to the nearest cubic inch is 9 cubic inches.

A sphere is a three dimensional figure which consists of set of all the points which are at an equal distance from a point called the center of the sphere.

Volume is the space occupied by a three dimensional object.

Given that,

Radius of a baseball = 1 3/10 inches = (1 × 10 + 3) / 10 = 13/10 inches.

Also we know that,

Volume of a sphere = 4/3 π r³, where r is the radius.

Volume of the baseball = 4/3 π (13/10)³

                                       = 4/3 π (1.3)³

                                       = 4/3 π × 2.197

Explanation:

The shorter side lengths 3 and 3 add to 3+3 = 6, which is not larger than the remaining side 9. This is why a triangle is not possible.

For a triangle to be possible, we need the sum of any two sides to be larger than the third side. Refer to the triangle inequality theorem.

I recommend making slips of paper that are 3 inches, 3 inches, and 9 inches long (or replace "inches" with "centimeters"). Then try to make a triangle with those slips of paper. You should find such a task is impossible: as mentioned, the 3 inch sides come up short when trying to attach to the 9 inch side.

The statement "It's not possible to build a triangle with side lengths of 3, 3, and 9" is true.

A triangle is a 2-D figure with three sides and three angles.

The sum of the angles is 180 degrees.

We can have an obtuse triangle, an acute triangle, or a right triangle.

We have,

A triangle cannot be formed with side lengths of 3, 3, and 9.

To form a triangle, the sum of the lengths of any two sides must be greater than the length of the third side.

However, in this case, the sum of the lengths of any two sides is 3+3=6, which is less than the length of the third side, 9.

Therefore, it is not possible to form a triangle with side lengths of 3, 3, and 9.

Thus,

The statement "It's not possible to build a triangle with side lengths of 3, 3, and 9" is true.

Answer:

4) 100

5) 120

Step-by-step explanation:

4) Number of sides in the polygon = n = 6

Sum of all the angles of n-sided polygon = (n -2)* 180

                                                                    = (6 - 2) *180

                                                                    = 4 * 180

                                                                    = 720

x + x + 9 + 90 + 120 +156 + 145 = 720

Combine like terms,

                             2x + 520  = 720

Subtract 520 from both sides,

                                           2x = 720 - 520

                                           2x = 200

Divide both sides by 2,

                                             x = 200÷2

                                             [tex]\sf \boxed{x = 100^\circ}[/tex]

5)    Sum of all the angles of 5 sided polygon = ( 5 - 2)*180

                                                                           = 3 * 180

                                                                            = 540

    x + x + x + x + 60 = 540

                    4x + 60 = 540

                            4x = 540 - 60

                             4x = 480

                               x = 480 ÷ 4

                               [tex]\sf \boxed{x = 120^\circ}[/tex]

Answer:

4.) You need 720 degrees sum for 6 sided polygon.

5.) You need 540 degrees for a 5 sided polygon.

Step-by-step explanation:

4.) -

120 + 156 + 145 + 90= 511

720 - 511 = 209.

209 - 9 = 200

200 / 2 = 100

X is equivalent to 100 Degrees

-

5.) -

Since X is the same for all sides we'll take 60 from 540 = 480

480 / 4 = 120

X = 120

An expression or mathematical expression is a finite collection of symbols that is well-formed according to context-dependent norms. In mathematics, an expression is a phrase that has at least two numbers or variables and at least one arithmetic operation. Addition, subtraction, multiplication, or division are all examples of math operations. A number, a variable, or a combination of numbers, variables, and operation symbols constitutes an expression. An equation consists of two expressions joined by an equal sign. Example of a word: the sum of 8 and 3. Example of a word: The product of 8 and 3 equals 11. 8 + 3 is an expression.

Here,

=quantity x squared minus 100 over quantity x squared plus 2 x minus 120 divided quantity 6 x plus 60 over quantity x minus 2

=((x²-100)/(x²+2x-120))/((6x+60)/(x-2))

Let's simplify some of the factors:

x² - 100 = x² - 10²

= (x - 10)(x + 10)            

6x + 60 = 6 * x + 6 * 10

= 6 * (x+10)

x² + 2x - 120 =  x² + 12x - 10x - 12 * 10

= (x * x - 10 * x) + (12 * x - 12 * 10)

= x(x - 10) + 12(x - 10)

= (x - 10)(x + 12)
