Step-by-step explanation:
2pie X r so. 2 X3.14X4.2
Answer:
26.376 cm
4 is the constant
Step-by-step explanation:
C = [tex]2\pi r[/tex]
To find the circumference, we first need to find the radius. The radius of a circle is half the diameter, so divide 84 by 2:
84/2 = 42
The radius is 42. Now we can solve for the circumference:
C = 2[tex]\pi[/tex](42)
C = 84[tex]\pi[/tex]
C = 263.89
The circumference is approximately 263.89 mm. Now we need to convert the millimeters to centimeters. There are 10 millimeters in 1 centimeter, so divide the circumference by 10:
263.89/10 = 26.389
The circumference is approximately 26.389 cm. The answer choice that our answer is closest to is the first answer choice.
4 + 2n
The constant in an expression is the value that doesn't change. After 2 and n are multiplied, that value will be different, so their values aren't constant. So, in this expression, 2 is the coefficient, n is the variable, and 4 is the constant.

5) The perimeter of the given square is 56cm. Construct an equation and hnd
the side of the square.
2x
Answer:
side = 14 cm
Step-by-step explanation:
Let 'x' be the side of the square.
Perimeter = 4 * side
= 4*x
= 4x
4x = 56
Solution:
4x = 56
Divide both sides by 4
x = 56/4
x = 14 cm

As the ratio is 5:3, it totals 8 parts. I would do 480 divided by 8 to get the number of pages per part, then multiply that number into the ratio.
480 / 8 = 60
The value of each part being 60 put into the ratio 5:3 = 60x5 : 60x3

Use a geometric model to factor x2 - 9 by following these steps:
Step 1: Model x2 - 9 by placing tiles in the product section. (Do not try and form a rectangle.)
Answer:(x-3) (x+3)
Step-by-step explanation:
The equation x^2 - 9 is modeled by placing tiles. The image is attached below.
What is tile modeling?It is the kind of modeling in which tiles are used to represent products. It provides a visual representation of the multiplication.
How can we make a model of multiplication?To make a model, first, we must factorize the expression.
The given expression is x^2 - 9.
This can be factored as shown below:
x^2 - 9 = (x - 3)(x + 3)
We must now make a horizontal row containing x, -1, -1, and -1.
Similarly, we must make a vertical column containing x, 1, 1, and 1.
Now we must multiply each row and columnn to together and add them together as shown below:
x^2 - x - x - x + x + x + x - 9 = x^2 -9
This is the same as the given expression.
Thus, we have modeled the given expression by placing tiles in the product section.

What is the slope of a line parallel to the line whose equation is 6x-2y=32
Answer:
Write this:
y= -3x + 1
Step-by-step explanation:
Solve the equation:
6x -2y = 32
Subtract 6x from both sides
-2y = -6x +32
divide by negative to on both sides
y = -3x -16
ANSWER:
y = -3x (any number ,negative or positive, except 16)
The slope of the line will be 3.
What is Equation of line?
The equation of line in point-slope form passing through the points
(x₁ , y₁) and (x₂, y₂) with slope m is defined as;
⇒ y - y₁ = m (x - x₁)
Where, m = (y₂ - y₁) / (x₂ - x₁)
Given that;
The equation of parallel line is,
⇒ 6x - 2y = 32
Now,
The slope of two parallel lines are always same.
So, We find the slope of the parallel line.
Since, The standard form of equation line is,
⇒ y = mx + c
Where, m is slope of the line.
So, We can change the equation of parallel line in the standard form.
The equation of parallel line is,
⇒ 6x - 2y = 32
Add 2y both side,
⇒ 6x - 2y + 2y = 32 + 2y
⇒ 6x = 32 + 2y
Subtract 32 both side,
⇒ 6x - 32 = 2y
⇒ 2y = 6x - 32
Divide by 2, we get;
⇒ y = 3x - 16
Compare with y = mx + c, we get;
The slope of the line (m) = 3
Thus, The slope of the line will be 3.

What is the best estimate for the value of the expression?
(34/8-16/3)-14/9
Answer:
The best estimate is -2.64
Step-by-step explanation:
To get the estimate value we are rounding all values to the nearest hundredth
You use BOMDAS/PEMDAS to do this expression
(34/8 - 16/3) - 14/9
= 4.25 - 5.33 - 14/9
= 4.25 - 5.33 - 1.56
= -1.08 - 1.56
= -2.64

Answer:
[tex](\pi 4^2 (9))-(\pi 2^2 (9))[/tex]
and
[tex]339.292 cm^3[/tex]
Step-by-step explanation:
This question is simple once you break it down.
Let's concentrate on the outer cylinder.
First, find the volume of the outer cylinder.
The volume of a cylinder is expressed as: [tex]V = \pi r^2 h[/tex]
Gathering information from the diagram..
d = 8 cm
h = 9 cm
You can get the radius from the diameter by just dividing the diameter by 2.
[tex]r = \frac{8}{2}=4[/tex]
r = 4
Plug everything into the volume equation.
[tex]V = \pi 4^2 (9)[/tex]
Don't solve just yet!
Now, find the volume of the inner cylinder.
Do the exact same thing as you did for the outer cylinder.
d = 4 cm
h = 9 cm
[tex]r = \frac{4}{2}=2[/tex]
r = 2
Plug everything into the volume equation..
[tex]V = \pi 2^2 (9)[/tex]
The question asks for an expression to represent the volume of the large cylinder after the cylindrical hole is removed. This means you need to subtract the volume of the cylindrical hole from the volume for the large cylinder.
Again, the volume for the large cylinder is [tex]V = \pi 4^2 (9)[/tex] and the volume for the cylindrical hole is [tex]V = \pi 2^2 (9)[/tex]
This means..
[tex](\pi 4^2 (9))-(\pi 2^2 (9))[/tex]
That is your answer to the first part of the question.
For the second part, just solve.
[tex](\pi 4^2 (9))-(\pi 2^2 (9))[/tex]
[tex](\pi*16*9)-(\pi*4*9)[/tex]
[tex](\pi*144)-(\pi*36)[/tex]
[tex]144\pi-36\pi[/tex]
[tex]108\pi[/tex]
[tex]339.292[/tex]
Don't forget the units.

n + q = 28
0.05n + 0.25q = 4
n + q = 4
5n + 25q = 28
n + q = 28
5n + 25q = 4
n + q = 4
0.05n + 0.25q = 28

Answer:
[tex]y=2x+7[/tex]
Step-by-step explanation:
Given the equation
[tex]y=-\frac{1}{2}x[/tex]
comparing the equation with the slope-intercept form
[tex]y=mx+b[/tex]
Here,
m is the slope y is the interceptso the slope of the line is -1/2
As we know that the slope of the perpendicular line is basically the negative reciprocal of the slope of the line, so
the slope of the perpendicular line will be: 2
Therefore, the point-slope form of the equation of the perpendicular line that goes through (-2, 3) is:
[tex]y-y_1=m\left(x-x_1\right)[/tex]
substituting the values m = 2 and the point (-2, 3)
[tex]y-3=2\left(x-\left(-2\right)\right)[/tex]
[tex]y-3=2\left(x+2\right)[/tex]
Add 3 to both sides
[tex]y-3+3=2\left(x+2\right)+3[/tex]
[tex]y=2x+7[/tex]
