Abdul wants to hang a square poster that measure 1 1/2 feet on a side in the center of a 12-foot-long wall. How far from the end of the wall should abdul place the side of the poster?
Answer:
5.25 feets
Step-by-step explanation:
Given the question :
Abdul wants to hang a square poster that measure 1 1/2 feet on a side in the center of a 12-foot-long wall. How far from the end of the wall should abdul place the side of the poster?
Length of one side of Square poster = 1 1/2 Feets = 3/2 feets
Length of wall = 12 feets long
Since Abdul wants the poster to be centered in the wall; then the picture should be placed such that there must be equal space left on either side of the wall after hanging.
Hence, (12/2 - 1 1/2) = (6 - 0.75) feets
= 5.25 feets
10-4x= -9x
I need help quick
Answer:
x = -2
Step-by-step explanation:
Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.
PEMDAS is the order of operation, and =
Parenthesis
Exponents (& Roots)
Multiplication
Division
Addition
Subtraction.
~
First, add 4x to both sides:
10 - 4x (+4x) = -9x (+4x)
10 = -9x + 4x
10 = -5x
Isolate the variable, x. Divide -5 from both sides:
-5x = 10
(-5x)/-5 = (10)/-5
x = 10/-5
x = -2
x = -2 is your answer.

The quotient of 2 and 9
y=3x+12 positive or negative
Answer:
x = -4 thus negative
Step-by-step explanation:
Solve for x:
3 x + 12 = 0
Hint: | Isolate terms with x to the left hand side.
Subtract 12 from both sides:
3 x + (12 - 12) = -12
Hint: | Look for the difference of two identical terms.
12 - 12 = 0:
3 x = -12
Hint: | Divide both sides by a constant to simplify the equation.
Divide both sides of 3 x = -12 by 3:
(3 x)/3 = (-12)/3
Hint: | Any nonzero number divided by itself is one.
3/3 = 1:
x = (-12)/3
Hint: | In (-12)/3, divide 12 in the numerator by 3 in the denominator.
12/3 = (3×4)/3 = 4:
Answer: x = -4

find the distance between each pair of points. round to the nearest tenth (-8,-2) and (6,-1)
Answer: 14
Step-by-step explanation:
To find the distance, find the difference in the x and y values,square them and add them. Then finally find the square root of the number you got after adding them together.
-2-(-1)= -1
-8 -6 = -14
-14^2 + -1^2 = d^2 where d is the distance
196 + 1 = d^2
197 = d^2
d= [tex]\sqrt{197}[/tex]
d= 14.0356 rounded to the nearest tenth is 14.

Which of the following pairs could be reasonable approximations for the diameter and circumference of a circle? 18 inches and 57 inches 3 centimeters and 28 centimeters 33 meters and 80 meters
Answer:
18 inches and 57 inches
Step-by-step explanation:
The diameter and the circumference of a circle are proportionate to each other.
The circumference of a circle will always be the diameter times [tex]\pi[/tex]. We know this because the circumference of a circle is represented as
[tex]2 \pi r[/tex]
Since the diameter is twice the radius, we multiply the radius by 2 - there's already a [tex]\cdot 2[/tex] in this equation, so [tex]c = \pi d[/tex].
1st option: [tex]18\cdot3.14 = 56.52[/tex], this is close to 57 so it's reasonable.
2nd option: [tex]3\cdot 3.14 = 9.42[/tex], this isn't close to 28 at all.
3rd option: [tex]33 \cdot 3.14 = 103.62[/tex], this isn't close to 80 at all.
So the 1st option is reasonable.
Hope this helped!
Answer:
First option: 18 inches diameter, 57 inches circumference
Step-by-step explanation:
Circumference of a circle is...
2 * radius * pi
We can approximate pi (3.14159...) to 3.
So the circumference of a circle is approx.
2 * radius * 3
We know the diameter of a circle is 2 times the radius...
diameter = 2 * radius
Thus, the circumference of a circle is approximately...
diameter * 3
First option:
Diameter 18, circumference 57
Let's try our approximation
18 * 3 = 54
We see that 57 is pretty close and is a reasonable approximation.
Second option:
Diameter 3, circumference 28
3 * 3 = 9
Not even close to 28.
Third option:
Diameter 33, circumference 80
3 * 33 = 99
Closer, but much further off than our first option.

let a and b be positive integers. 23^a x 23^b
Answer:
23 ^ ( a+b)
Step-by-step explanation:
23^a *23^b
Since the bases are the same, we can add the exponents
23 ^ ( a+b)
Answer:
23^(a+b)
Step-by-step explanation:
A^x*A^y = A^(x+y)
you can think of it like this
A^x = A*A*A*.......*A x times
A^y = A*A*A*....*A y times
therefore A^x * A^y = A*A*A*...*A (x+y) times
=A^(x+y),
so in our case A = 23, and x and y were a and b, so 23^a * 23^b = 23^(a+b)

An altitude of a three-dimensional object is best described as option D, "a segment that is perpendicular to the planes containing the two bases."
What is 3d geometry?3D geometry is the study of shapes in 3D space using three coordinates: x-coordinate, y-coordinate, and z-coordinate. To discover the exact location of a point in 3D space, three criteria are required.
An altitude is a line segment drawn from a vertex of a three-dimensional object (such as a pyramid or cone) that is perpendicular to the plane including the base of the object. The altitude can be used to find the height of the object, which is the distance from the vertex to the base along the altitude.
For example, in a pyramid, the altitude is a line segment drawn from the apex (the top vertex) to the center of the base that is perpendicular to the base. In a cone, the altitude is a line segment drawn from the apex to the center of the circular base that is perpendicular to the base.

What type of parent function is this? What is the domain and range of this function? write it in interval notation
Answer:
See below.
Step-by-step explanation:
This is a parabola. Therefore, it is a quadratic parent function. The quadratic parent function is:
[tex]f(x)=x^2[/tex]
The domain of the parent quadratic function is all real numbers.
The range of the parent quadratic function is all y-values greater than or equal to 0. From the graph, we can see that the graph never goes below 0.
So, the domain in interval notation is:
[tex](-\infty,\infty)[/tex]
And the range in interval notation is:
[tex][0,\infty)[/tex]
This is interpreted as all values greater than or equal to 0.
And we're done!
