I now the shape for not cubes i need explain
Answer:
The bottom right, middle top, and bottom left are NOT cubes.
Step-by-step explanation:
Cubes are defined as a three dimensional object with the same length, width, and height. Since the square on the bottom left is two dimensional, It is not a cube. Since the hexagon on the bottom right is two dimensional, It can't be a cube. The Middle top shape doesn't have the same length height as it's width is, so it is not a cube. The rest are cubes.

Find the value of x rounded to the nearest tenth
Applying the angle bisector theorem, the value of x is: B. 5.3.
What is the Angle Bisector Theorem?An angle bisector divides an angle into two congruent halves. According to the angle bisector theorem, an angle bisector of a triangle divides the interior angles opposite sides in such a way that the corresponding lengths are proportional to each other. This means that the corresponding sides have ratios that are equal.
How to Apply the Angle Bisector Theorem to Find x?In the image given, applying the angle bisector theorem, we have the following proportion which we can use to find the value of x in the triangle given above:
6/x = 9/8 [according to the angle bisector theorem]
Cross multiply
(9)(x) = (6)(8)
9x = 48
Divide both sides by 9
9x/9 = 48/9
x = 5.333
Thus, to the nearest tenth, the value of x is approximately calculated as: B. 5.3

Idk what the question meant. How would you do the area of a triangle
Answer:
750 sq. ft
Step-by-step explanation:
To understand the area of a triangle, we can start with the area of a rectangle. The area of a rectangle with some length (which I'll call L) and some width (which I'll call W) is just the product of those two values, L × W. How does this carry to triangles? Well we can take any triangle we want and draw a rectangle around it, using the base of the triangle as one of the rectangle's sides.
Now, the key here is to cut that original rectangle into two smaller ones, starting at the top point of the triangle. Notice now that half of the left rectangle is taken up by the orange triangle, and half of the right one as well. Putting those two together, we can say that the big orange triangle takes up exactly half of the green rectangle, or in other words, its area is (L × W) ÷ 2. Of course, when we talk about triangles, we use the words "base" (B) and "height" (H) rather than length and width, so you could also say that the area of a triangle is (B × H) ÷ 2.
Taking this into our problem, we're given a base of 100 ft and a height of 15 feet; using our newly-discovered equation, we find its area to be
(100 × 15) ÷ 2 = 1500 ÷ 2 = 750 sq. ft.
A sandwich shop sells sandwiches for $5.95 each, including tax. The shop received a total of $71.40 from the sounds of sandwiches one afternoon. Which equation can be used to determine the number of sandwiches, X,sold by the the sandwich shop that afternoon?
A:5.95+x equals 71.40.
B:5.94 divided 71.40 equals.
C:5.95x equals 71.40
D:5.95 divided times equals 71.40.
Answer:
C
Step-by-step explanation:
5.95(x)=71.40
7140/595=12
5.95(12)=71.40
The correct equation to find the number of sandwiches sold, X, is C: 5.95X = 71.40, which shows a direct correlation between the price per sandwich and the total income.
The question asks which equation can be used to determine the number of sandwiches, X, sold by the sandwich shop one afternoon given that each sandwich is sold for $5.95 and the total revenue is $71.40. The correct choice is C: 5.95X = 71.40. This is because to find the number of sandwiches sold (X), we need an equation that relates the price per sandwich to the total income from selling X number of sandwiches. Here, each sandwich is $5.95, and when you multiply that by the number of sandwiches sold, you should get the total sales of $71.40. Therefore, the equation is 5.95X = 71.40, where you can solve for X to find the total number of sandwiches sold.
Given that the points (-3, 2) and (1, 2) are vertices of a square, what two sets of coordinates could form the other two vertices?
The given points have the same Y value.
Find the distance between the X values -3 to 1 is 4 units.
All sides of a square are the same length so the other points must be 4 units away.
Add 4 units to the Y values:
(-3,2) = (-3,(2+4)) = (-3,6)
(1,2) = (1,(2+4)) = (1,6)
Two other points to make a square could be (-3,6) and (1,6)

A polynomial function has a zeros at -1,2,7 and all are multiplicity of 1 write a function in standard form that could represent this function
Final answer:
To create a polynomial with zeros at -1, 2, and 7, each with a multiplicity of 1, you start with the factored form (x + 1)(x - 2)(x - 7) and expand it to get the standard form x^3 - 8x^2 + 15x + 14.
Explanation:
The question involves finding a polynomial function with given zeros. When a polynomial has zeros of -1, 2, and 7, all with a multiplicity of 1, the function can be expressed as product of linear factors associated with each zero. Starting from the factored form f(x) = (x - (-1))(x - 2)(x - 7), which encapsulates the given zeros, you can then expand this expression to get the polynomial in its standard form.
The expanded form of the polynomial is then f(x) = (x + 1)(x - 2)(x - 7), which, when expanded, yields f(x) = x^3 - 8x^2 + 15x + 14. This is a polynomial function in standard form that has the required zeros, each with a multiplicity of 1.

part: c
The solution to the equation is x =
a)
Subtract 0.4 from both side.
-9x +0.4 = 4
-9x + 0.4 - 0.4 = 4 - 0.4
-9x = 3.6
b)
divide by -9 both side
-9x/-9 = 3.6/-9
x = -0.4
c) x = - 0.4
The steps needed to solve the given equation is required.
Adding the opposite value of the constant to both sides.
Divide both sides by the coefficient of the variable.
The solution to the equation is [tex]x=-0.4[/tex]
The given equation is
[tex]-9x+0.4=4[/tex]
In order to solve this we first move constants to the side opposite of the variable.
This is done by adding the opposite value of the constant to both sides.
[tex]-9x+0.4-0.4=4-0.4[/tex]
Here [tex]0.4[/tex] is the constant so we add [tex]-0.4[/tex] to both sides.
[tex]\Rightarrow -9x=3.6[/tex]
Now, we divide both sides by the coefficient of the variable.
[tex]\Rightarrow \dfrac{-9x}{-9}=\dfrac{3.6}{-9}\\\Rightarrow x=-0.4[/tex]
The solution to the equation is [tex]x=-0.4[/tex]

A number cube is rolled 300 times. Predict how many times a number greater that 3 would be rolled
Answer:
150
Step-by-step explanation:
4, 5 and 6 are all numbers greater than 3.
The chances of rolling a 4 is 1/6, that of a 5 is 1/6, and that of a 6 is 1/6.
The chances of rolling a number greater than 3 is thus 3/6, or 1/2.
This is theoretical probability; you haven't actually observed this happening.
We can now multiply (300 rolls) by this probability 1/2, obtaining 150.
We predict that in 300 rolls, 150 numbers greater than 3 would be rolled.

what’s the solution to x-4y=-8 and 2x-3y=-16
Answer: [tex]x=-8\\y=0[/tex]
Step-by-step explanation:
You can apply the elimination method:
- Multiply the first equation by -2.
- Add both equations to cancel out the variable x.
- Solve for y:
[tex]\left \{ {{(-2)(x-4y)=-8(-2)} \atop {2x-3y=-16}} \right.\\\\\\\left \{ {{-2x+8y=16} \atop {2x-3y=-16}} \right.\\ ------\\5y=0\\y=0[/tex]
- Substitute y=0 into any of the original equations ans solve for x. Then:
[tex]x-4(0)=-8\\x=-8[/tex]
The answers are:
[tex]x=-8\\y=0[/tex]
Why?Since we have to equations, first we need to isolate one variable, and then substitute it into the other equation.
So, isolating x from the first equation we have:
[tex]x-4y=-8\\x=-8+4y[/tex]
Then, substituting "x" into the second equation, we have:
[tex]2(-8+4y)-3y=-16\\-16+8y-3y-=-16\\5y=-16+16\\5y=0\\y=\frac{0}{5}=0[/tex]
Therefore, substituting "y" into the first equation, we have:
[tex]x-4(0)=-8\\x-0=-8\\x=-8[/tex]
So, the solutions for the system of equation are:
[tex]x=-8\\y=0[/tex]

Answer:
A- Students who do not act
B- Every 4th student selected from an alphabetical register of the club
E- Students whose names are randomly selected from a hat
Step-by-step explanation:
A drama teacher wants to decide where the drama club should go to celebrate their performance.
We are to determine whether which of the options is not a representative sample.
By definition, a sample which is the subset of the bigger population reflecting the characteristics is said to be a representative sample.
So the correct options are:
A- Students who do not act
B- Every 4th student selected from an alphabetical register of the club
E- Students whose names are randomly selected from a hat
Answer:
A- Students who do not act.B- Every 4th student selected from an alphabetical register of the club.E- Students whose names are randomly selected from a hat.Step-by-step explanation:
The objective is to determine where the drama club should go to celebrate their final performance.
In orther to achieve that objective, the sample must be representative. For example, the sample must be formed by students that actually acts.
Therefore, A, B and E are not representative samples because they don't act, every 4th student selected doesn't imply that all of them act, and selecting randomly names won't represents students that actually acts.
