How many pattern block trapezoids would create for hexagons?
2 trapezoids compose a hexagon using equal-size shapes: 2 trapezoids, 6 triangles, or 3 blue rhombuses. compose hexagons using different shapes. So 2 trapezoids create 1 hexagon. This means 6 trapezoids make 3 hexagons.
The exact number of trapezoids needed to create three hexagons depends on the size and shape of the hexagons.
However, in general, you would need at least 18 trapezoids.
What is Hexagon?An hexagon is a six-sided polygon. It is made up of six equilateral triangles and six trapezoids.
If you are looking to create larger hexagons you will need more trapezoids.
Depending on the size and shape, you could need as many as 24 or more trapezoids.
An hexagon is a six-sided polygon. It is made up of six equilateral triangles and six trapezoids.
Hence, To create an hexagon using pattern blocks, you need 10 equilateral triangles and 20 trapezoids.
Therefore, to create 5 hexagons.

Solve 2 ―8―33 = 0 by factoring.
Answer:
the equation 2 - 8 + 33 = 0 can be factored as 27 = 0, which is a verified answer
Step-by-step explanation:
To factor the equation 2 - 8 + 33 = 0, we start by collecting all the terms on one side of the equation:
2 - 8 + 33 = 0
becomes
33 - 8 + 2 = 0
Next, we can rewrite this as:
33 - 6 = 0
Finally, we factor the left-hand side of the equation to get:
33 - 6 = (33 - 3) - 3 = 30 - 3 = 27 - 0
So the factored form of the equation 2 - 8 + 33 = 0 is 27 = 0.
Verification: We can verify that the factored form of the equation is correct by substituting 0 for 27 and checking that the equation holds. So, if we replace 0 for 27 in equation 27 = 0, we get:
27 = 0, which is true.
Therefore, the equation 2 - 8 + 33 = 0 can be factored as 27 = 0, which is a verified answer.

The population of rabbits on an island is growing exponentially. In the year 2000, the population of rabbits was 950, and by 2003 the population had grown to 1000. Predict the population of rabbits in the year 2013, to the nearest whole number.
The population of rabbits in the year 2013 is 1186.
How to predict the population of rabbits in the year 2013?
To predict the population of rabbits in the year 2013, we can use exponential growth. The formula for exponential growth is:
P = P₀ * e^(rt)
where:
P = final population
P₀ = initial population (950)
r = the growth rate (we need to find this)
t = time elapsed (13 years)
We can use the data from 2003 to find the growth rate:
1000 = 950 * e^(r * 3)
1000 = 950 * e^(3r)
1000/950 = e^(3r)
ln (1000/950) = 3r
r = (ln(1000 / 950)) / 3
r = 0.0171
Now that we have the growth rate, we can use it to find the population in 2013:
P = 950 * e^(0.0171 * 13)
P = 1186

Solve the following system of inequalities graphically on set of axes below. State the coordinates of a point in the solution set.
Answer:
see below for a graph
(-8, 4) is in the solution set
Step-by-step explanation:
You want the graph and a solution point for the inequalities y ≤ -6/5x -4 and y ≥ 2/5x +4.
GraphThe solid boundary line of the first inequality will cross the y-axis at -4, and will have a "rise" of -6 units for each "run" of 5 units. Shading is below this boundary line.
The solid boundary line of the second inequality will cross the y-axis at +4 and will have a "rise" of 2 units for each "run" of 5 units. Shading is above this boundary line.
Solution setThe boundary lines make an X shape on the graph, crossing at the point (-5, 2). The solution set is in the left quadrant.
Point (-5, 2) is in the solution set, as are points in the doubly-shaded space to its left. (-8, 4) is one of those.
__
Additional comment
The boundary lines are solid because the "or equal to" case is included in each.
The ≤ symbol tells you y-values that satisfy the first inequality will be less than (or equal to) those on the boundary line.
The ≥ symbol tells you y-values that satisfy the second inequality will be greater than (or equal to) those on the boundary line.
If it takes 2 cups of rice to make 5 servings, how many cups of rice are needed to make 12 servings?
12 servings of rice require six cups of rice. In order to make 12 servings, 6 cups of rice would be needed, or 2/5 of a cup.
1. It takes 2 cups of rice to make 5 servings.
2. Divide 12 by 5 to determine how many cups of rice are required to prepare 12 servings.
3. The final product is 2.4 cups.
4. Round up to the nearest whole number, which is 6 cups, to get 12 servings.
You will require 6 cups of rice to produce 12 servings of rice. The number of servings that can be made from 2 cups of rice can be used to determine this. 5 servings can be produced from 2 cups of rice. This indicates that 2/5 of a cup of rice is needed for each serving. Divide 12 by 5 to see how many cups of rice are required for 12 servings. This results in 2.4 cups of liquid. Round the amount up to the nearest whole number, which is 6 cups, to make 12 servings. 6 cups of rice are therefore required to make 12 servings.

What is Parallelogram ?A different type of quadrilateral known as parallelogram has both pairs of its opposite sides parallel and equal.
The figure shows a parallelogram ABCD with the parameters AB II CD and AD II BC. Furthermore, AB = CD and AD = BC.
In a parallelogram, the opponent angles are equal.. So it means that side /A is equal to side /C, let's equate the two angles and solve for x;
5y - 3 = x + 3y
2y - x = 3 ........(1)
Also, consecutive angles of a parallelogram are supplementary,
therefore,
/C + /D = 180
x + 3y + 2x = 180
3x + 3y = 180
x + y = 60 .......(2)
Now, add equations (1) and (2)
(2y-x) + (y+x) = 3 + 60
3y = 63
y = 21
now put this value of y in (2) we get,

For given linear equations, 27hx -9y = -18 and y = 1 - 6x

What is a linear equation, exactly?
When the greatest power of a variable is 1, the equation is said to be linear. Another term for it is a one-degree equation. The standard form of a linear equation with one variable is Ax + B = 0. There are three variables in this equation: x, A, and B. A denotes a coefficient. A linear equation with only two variables is commonly written as Ax + By = C. There are three more constants in addition to the constant C: the variables x and y, the coefficients A and B, and the variables.
Now,
As general equation of a line is y=mx + c where m=slope and c=constant
and here given lines are 27hx -9y = -18 and y = 1 - 6x
transforming these into general equations
y=-3hx+2 where m=-3h
and y=-6x+1 where m=-6
Now As slope of parallel lines is equal
therefore, -3h=-6
h=6/3
h=2

a certain bacteria population obeys the population growth law. it is observed that the doubling time for the population is 4 hours. the length of time it will take for the population to increase to 3-times its original population is
According to the population growth law, the size of a population grows exponentially over time, with a growth rate proportional to population size. If the population doubling time is t, then the population size P can be written as:
[tex]P = P_0 * 2^{t/t_d)}[/tex]
where P_0 is the initial population size, t is the time elapsed, and t_d is the doubling time.
To find the time it will take for the population to increase to 3 times its original population size, we can set [tex]P = 3P_0[/tex] and solve for t:
[tex]3P_0 = P_0 * 2^{t/t_d}[/tex]
Dividing both sides by [tex]P_0[/tex] gives:
[tex]3 = 2^{t/t_d}[/tex]
Taking the logarithm of both sides (using any base) gives:
[tex]log(3) = log(2^{t/t_d} )[/tex]
Using the logarithmic identity
[tex]log(a^b) = b*log(a),[/tex]
we can rewrite this as:
[tex]log(3) = (t/t_d)*log(2)[/tex]
Solving for t, we get:
[tex]t = t_d * (log(3)/log(2))[/tex]
Substituting [tex]t_d[/tex] = 6 hours (given in the problem), we get:
[tex]t = 6 * (log(3)/log(2)) hours[/tex]
Simplifying using the change of base formula
[tex](log(a)/log(b) = log_b(a))[/tex], we get:
[tex]t = 6 * log_2(3)[/tex] hours

Based on the given results, Shaniece selected a lime chew 24 times out of 57 selections. To estimate the expected number of times she would select a lime chew in the next 1200 selections, we can use the proportion of lime chews selected in the first 57 selections:
The proportion of lime chews selected = 24/57
To estimate the expected number of lime chews in the next 1200 selections, we can multiply the proportion by the total number of selections:
expected number of lime chews in the next 1200 selections = (24/57) x 1200
The expected number of lime chews in the next 1200 selections = 505.263
Rounding to the nearest whole number, we would expect Shaniece to select a lime chew about 505 times in the next 1200 selections.

I get 64% off a table the sale price is $72, what is the original price?
The original price of the table was $200 before the 64% discount was applied.
What is the percentage?
Percentage is a way of expressing a fraction or proportion out of 100. It is commonly used to compare two quantities, indicate the change or growth of a quantity over time, or express the probability or chance of an event occurring.
If you received a 64% discount on the sale price of a table, and the sale price is $72, we can calculate the original price of the table as follows:
Determine the percentage of the original price that corresponds to the sale price after the discount:
If the sale price is 100% - 64% = 36% of the original price, after the 64% discount.
Use the percentage found in step 1 to calculate the original price:
Let x be the original price
x * 36% = $72
0.36x = $72
x = $72 / 0.36
x = $200
Therefore, the original price of the table was $200 before the 64% discount was applied.
