Answer: x = 174, and x < 174.
Let the number be x.
Then 1/3 of the number = 1/3*x
1/3*x is decreased by 36 is the same as 1/3*x - 36
If 1/3*x - 36 is at most 22, we can write:
1/3*x - 36 is less than or equal to 22.
Therefore,
1/3*x - 36 <= 22
1/3*x - 36 = 22 (i), and 1/3*x - 36 < 22 (ii)
From (i):
1/3*x = 22 + 36 = 58, or x = 58 * 3 = 174.
From (ii):
1/3*x < 22 + 36 = 58, or x < 58 * 3 , or x < 174.
Therefore,
x = 174, and x < 174.

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.

Yolanda paid for her movie ticket using 28 coins, all nickels and quarters. The ticket cost $4. Which system of linear equations can be used to find the number of nickels, n, and the number of quarters, q, Yolanda used?
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:
n + q = 28 0.05n + 0.25q = 4

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.

6 is ones
1 is tens
3 is hundreds
4 is thousands
therefore the answer is 4300
If 4316 is rounded to the nearest 100 then its value will be, 4300
What is Rounding of a number ?Rounding means making a number simpler but keeping its value nearby original value.
Rules for rounding nearest 100:-
1. If the number's final two digits are 50 or higher, we round it up to the next hundred.
2. If the number's final two digits are 49 or less, we round it down to the closest hundred.
3. If the final two numbers are 00, there is no need to round because the number is already one hundred.
We have given number, 4316
Number's final two digits are less than 49
Hence, The rounded value is 4300

Step-by-step explanation:
If it takes 6 men 4 days to dig a hole 3 metres deep, how long will it take 10 men to dig same hole 7 metres deep?
Step-by-step explanation:
6 men → 4 days → 3 metres
1 man → 24 days → 3 metres
1 man → 8 days → 1 metres
1 man → 56 days → 7 metres
10 men → 5.6 days → 7 metres
therefore, 5.6 days
Topic: direct n inverse proportions
If you like to venture further, do check out my insta (learntionary) where I constantly post math tips! Thanks!
Answer:
It will take 5.6 days for the 10 men to dig the same hole 7 m deep.
Step-by-step explanation:
Laying the data in column
----------------------------------------------------
6 men 3 m hole 4 days
10 men 7 m hole x days
-----------------------------------------------------
As [tex]6[/tex] men dig a hole in [tex]4[/tex] days, so their rate will be:
[tex]rate\:=\:\frac{4}{3}[/tex]
Then [tex]6[/tex] men would take [tex]7\times \frac{4}{3}=\frac{28}{3}[/tex] days to dig a hole of depth 7 m.
As we are letting 10 men do work, so they would
take [tex]\frac{6}{10}\times \frac{28}{3}=\frac{28}{5}[/tex] days.
so
[tex]\frac{6}{10}\times \frac{28}{3}=\frac{28}{5}[/tex]
[tex]=5.6[/tex] days
Therefore, it will take 5.6 days for the 10 men to dig the same hole 7 m deep.
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.

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]
