An inequality in standard form that describes this situation is 25x + 59y ≤ 495.
How to write an inequality that represents this situation?In order to write an inequality that represents or describes this situation, we would assign variables to the number of nails required by the small birdhouse and large birdhouse respectively, and then translate the word problem into algebraic equation as follows:
Let the variable x represent the small birdhouse.Let the variable y represent the large birdhouse.Since Tanner has a total of 495 nails on hand and a small birdhouse requires 25 nails while a large birdhouse requires 59 nails, an inequality that represents or describes this situation can be written as follows;
25x + 59y ≤ 495.
In conclusion, we can reasonably infer and logically deduce that the total number of nails required by both the small birdhouse and large birdhouse is less than or equal to 495 nails.

What is Equation?Two or more expressions with an Equal sign is called as Equation.
Let y represents the total cost of the party, and x represents the number of the people attending the party.
The hockey suite costs $130 to rent the room and $30 per person.
y=130+30x
The basketball suite costs $180 to rent the room and $20 per person.
y=180+20x
So option c is correct and
If there was going to be a total of 4 people attending the party,
y=130+30(4)=250
y=180+20(4)=260
basket ball is most cost efficient.
If there was an amount of people that could attend the party so that both games would cost the same
130+30x=180+20x
10x=50
x=5
So 5 people could attend the party.
The sum of two numbers is 32
The difference is 18
x+y=32
x-y=18
x+y+x-y=32+18
2x=50
Divide both sides by 2
x=25
y=7
The two numbers are 25 and 7.
Hence, y = 30x + 130 and y = 20x + 180 is the system of equations that represents the model and The two numbers are 25 and 7 in second question.

The hexagon's side length is 4.5 inches whereas the equilateral triangle's side length is 9.
How do you determine a triangle's angle?While an exterior angles are equivalent to the sum of the twin interior angles that become not directly adjacent to it, the inside angles necessarily add up to 180°. By lowering the inclination of the target vertex from 180°, one may also get a triangle's exterior angle.
The equilateral triangle's side length is 9 inches.
The hexagon's sides measure 4.5 inches long.
The equilateral triangle's side length is equal to 1.4x plus 2.
Perimeter = 3(1.4x + 2) = 4.2x + 6 as a result.
The hexagon's side length is equal to 0.5x plus 2.
The perimeter is 6(0.5x + 2) = 3x + 12 as a result.

M'n'o'p' has vertices at m'(-5, -4), n'(6, 4), o'(6, 7), and p'(3, 7). the center of dilation is the origin, mnop has vertices at m(4.5, 6), n(9, 6), o(9, 10.5), and p'(4.5, 10.5). what is the algebraic representation of this dilation?
The algebraic representation of this dilation is: (x', y') = (-0.9x, -1.5y)
How is this caclulated?A dilation is a transformation that changes the size of a geometric figure, but not its shape. The center of dilation is a fixed point, and all other points in the figure are expanded or contracted in relation to it. In this case, the center of dilation is the origin, and the original figure is m'n'o'p' and the image figure is mnop.
The algebraic representation of a dilation is given by the equation:
(x', y') = (kx, ky)
Where (x', y') are the coordinates of the image point, (x, y) are the coordinates of the original point and k is the scale factor of the dilation.
We can find the scale factor k by comparing the coordinates of any two corresponding vertices of the figures. For example, if we take the vertex m' and m, we have:
m'(-5, -4) and m(4.5, 6)
Here we can see that the x-coordinate of m' is -5 and the x-coordinate of m is 4.5 and the y-coordinate of m' is -4 and the y-coordinate of m is 6.
So, k = mx/mx' = 4.5/-5 = -0.9 and k = my/my' = 6/-4 = -1.5
We can use this scale factor to find the coordinates of any other point in the image figure.
Therefore, the algebraic representation of this dilation is: (x', y') = (-0.9x, -1.5y)

About Geometry sequenceA geometric sequence is a sequence that satisfies the quotient of a term with the preceding terms which are of course consecutive. This thing has a constant value. Not only that, geometric sequences are also known as 'measurable sequences' which are still closely related to arithmetic sequences and series.
Examples of geometric sequences are a, b, and c. Then c/b = b/a = constant, this is where the quotient of adjacent terms will be obtained and then it is said to be the ratio of the geometric sequence which is given the symbol "r".
Another example, which is much easier to understand, is for example, if you have a sequence and a series: 2, 4, 8, 16, 32, ….. etc., then from the sequence and series it can be seen between the first and second terms and so on, have the same multiplier.
So, to find the nth term, you can easily find the ratio first. By knowing 'r', then you will easily find Tn.

Answer:
a) In order to write the ratio h:k in its simplest form, we need to find the greatest common divisor (GCD) of h and k and divide both h and k by that value.
The GCD of 2 and 6 is 2.
So the simplified ratio h:k is 2/2:6/2 = 1:3
b) In order to write the ratio k:l in its simplest form, we need to find the greatest common divisor (GCD) of k and l and divide both k and l by that value.
The GCD of 6 and 9 is 3.
So the simplified ratio k:l is 6/3:9/3 = 2:3
Answer:
the ratio of h and k in simplest form is 1:3
the ratio of k and l is 2:3

The area of the circle is increasing at a constant rate of 5 square centimeters per second. At what rate, in centimeters per second, is the radius increasing at the instant when the radius is 5 centimeters
The rate in centimeters per second, at which the radius is increasing at the instant when the radius is 5 centimeters is 0.16 cm/s.
What is the Rate Of Change?Using a known value of a function at a certain point along with its rate of change at that moment, one application of derivatives is to estimate an unknown value of a function at a particular point.
Given:
Both radius r and area A is a function of time, so in fact:
A(t) = π [r(t)]²
Deriving this we get that the area changes and the radius changes as:
[tex]\frac{dA(t)}{dt} = 2\pi r(t)\frac{dr(t)}{dt}[/tex]
But,
[tex]\frac{dA(t)}{dt} = 5 \frac{cm^{2} }{s}[/tex]
Considering when r(t) = 5cm at the instant we get,
[tex]5 = 2\pi . 5\frac{dr(t)}{dt}[/tex]
Simplify 5 and take 2π to the other side and divide,
The rate of change of radius is given by:
[tex]\frac{dr(t)}{dt} =\frac{1}{2\pi } = 0.16 cm/s[/tex]

a student reads 56 pages in 4 hours, how many pages will they read in 7 hours what is the constant variation and is it direct or inverse?
The number of pages that the student will read in 7 hours, given the number of pages read in 4 hours, is
The constant variation is 14 pages.
This constant variation is direct.
What is the constant variation ?The quantity that connects two variables that are directly or inversely proportional to one another is known as the constant of variation.
Variation in mathematics demonstrates how one variable fluctuates in respect to another. Typically, a ratio is used to illustrate this relationship. When we remark that a variation is continuous, we are referring to how consistently the ratio changes.
The constant of variation in this instance therefore, is:
= Number of pages read / Number of hours
= 56 / 4
= 14 pages
This constant of variation is direct.
The number of pages read in 7 hours is:
= Constant of variation x number of hours
= 14 x 7
= 98 pages

The top of a square table is covered with four equal square tiles. If the side length of each tile is decreased by 75% , how many tiles of the new size would be needed to cover the same table?
Answer:
16
Step-by-step explanation:
The side lengths of the original square was 2. 2 x 2 = 4
.25 x 2 = .5
The squares are now 1/2 x 1/2. One of the 4 original squares will now need 4 new smaller size squares to cover the one square.
4 x 4 = 16
Given the polynomial Q(x)=4x^3-3x+1, find the polynomial P(x) such that P(x)=2*(Q(x)+P(x)) for any real number x
Given the polynomial Q(x)=4x^3-3x+1,
P(x) = 8x^3 - 6x + 2
What is the polynomial?Generally, To find P(x), we can start by substituting
P(x) = 2*(Q(x) + P(x)) into the equation:
P(x) = 2*(Q(x) + P(x))
This simplifies to:
P(x) = 2*(4x^3 - 3x + 1 + P(x))
Expanding and rearranging the equation gives:
P(x) = 8x^3 - 6x + 2 + 2P(x)
Subtracting 2P(x) from both sides of the equation gives:
P(x) - 2P(x) = 8x^3 - 6x + 2
This simplifies to:
-P(x) = 8x^3 - 6x + 2
Adding P(x) to both sides of the equation gives:
0 = 8x^3 - 6x + 2 + P(x)
Therefore, the polynomial P(x) that satisfies the equation
P(x) = 2*(Q(x) + P(x)) is:
P(x) = 8x^3 - 6x + 2
