Converting 33 cubic feet to cubic centimeters would give 934454. 4 cubic centimeters
How to determine the conversionIt is important to note that conversion of units requires the appropriate equivalent values
For
I cubic foot is equivalent to 28316. 8 cubic centimeters
But we were given
33 cubic feet for the conversion
If 1 cubic foot = 28316. 8 cubic centimeters
Then 33 cubic feet = x
Cross multiply, we get
x = 28316. 8 × 33
x = 934454. 4 cubic centimeters
Thus, converting 33 cubic feet to cubic centimeters would give 934454. 4 cubic centimeters

The first step in the construction of a line perpendicular to line AB and passing through an external point m is:
a. place the compass needle on m and keeping the compass width the same, draw two arcs that intersect the line AB
What are the steps to construct a perpendicular line from an external point?To construct a perpendicular line, a compass and a scale are used.
Consider a line AB and an external point M.
Step 1:
Place the compass needle on M and keeping the compass width the same, draw two arcs that intersect the line AB.
Step 2:
Name the two intersecting points on line AB as X and Y.
Draw the arcs from these two points to the opposite side of point M with the same compass width.
Step 3:
Name the intersecting point of two arcs as N.
Draw a line connecting the two points M and N using scale.
Step 4:
Using a protractor, measure the angle of the line MN with the line AB.
The angle must show 90°.
Thus, the line MN perpendicular to line AB and passing through an external point M is constructed.

Revenue function: r(x) = 60x cost function: c(x) = 12 + 7x profit function: p(x) =
Profit function : p(x) = 53 x - 12
Cost is the total cost of producing the output.
The cost function consists of two different types of costs:
- Variable costs
- Fixed costs.
Variable costs vary with output (number of units produced). Total variable costs can be
expressed as the product of variable costs per unit and the number of units produced. If there are multiple items
manufactured costs are higher.
Fixed costs usually do not vary with performance.
Revenue is the total payment received from the sale of goods or the provision of a service.
The revenue function R() reflects the revenue from selling “” quantity of output items at price
"p" after item.
() =
Profit functions
The profit function P() is the difference between the revenue function R(x) and the total cost function C()
So P() = R() – C()
=−
Now, Profit = Revenue - Cost
= 60 x - ( 12 + 7 x)
= 60 x -12 -7 x
Profit = 53 x - 12

Cost of 4 tables and 3 chairs is $225 and 3 tables and 4
chairs cost $195. Find the cost of 2 chairs and 1 table.
The cost of 2 chairs is = $30
The cost of 1 table = $60
Step-by-step explanation:
Let a table represent x
A chair represents y
4x + 3y = 225.......eq 1
3x + 4y = 195........eq 2
Use elimination method
x - y = 30
x= 30 + y...... Eq 3
Substitute the value of x into equation 1
4(30+ y) + 3y= 225
120 + 4y + 3y= 225
7y + 120= 225
7y= 225-120
7y= 105
y= 15
Substitute the value of y in eq 2
3x + 15 = 195
3x= 195-15
3x= 180
x= 60
Therefore, the cost of 2 chairs is 15 * 2= $30

The equation of the line is 3x + y = 1
How to determine the equation of the line?The points are given as:

Evaluate
m = -3
The equation is then calculated as:

Ben has typed 180 and can type 30 words per minute. millie has typed 60 and can type 50 words per minute. how many minutes will it take for millie to catch up with ben.
The time taken by Millie to catch up with Ben is 6 minutes, solved using the linear equation in one variable and the unit rates provided.
We assume the minutes taken by Millie to catch up with Ben to be x minutes.
The number of words Ben has already typed = 180.
The unit rate for Ben for the typing of words = 30 per minute.
Therefore, words typed by Ben in x minutes = 30x words.
Therefore, the total number of words typed by Ben = 180 + 30x words.
The number of words Millie has already typed = 60.
The unit rate for Millie for the typing of words = 50 per minute.
Therefore, words typed by Millie in x minutes = 50x words.
Therefore, the total number of words typed by Millie = 60 + 50x words.
As Millie needs to catch up with Ben after x minutes, the total number of words typed by them needs to be equal, that is, 60 + 50x = 180 + 30x, which is the required linear equation in one variable.
To find the minutes taken by Millie to catch up with Ben, we solve this linear equation in one variable as follows:
60 + 50x = 180 + 30x,
or, 60 + 50x - 30x = 180 + 30x - 30x {Subtracting 30x from both sides},
or, 60 + 20x = 180 {Simplifying},
or, 60 + 20x - 60 = 180 - 60 {Subtracting 60 from both sides},
or, 20x = 120 {Simplifying},
or, 20x/20 = 120/20 {Dividing both sides by 20},
or, x = 6 {Simplifying}.
Thus, the time taken by Millie to catch up with Ben is 6 minutes, solved using the linear equation in one variable and the unit rates provided.

Answer:
b = 21
Step-by-step explanation:
In general for these trig problems look for the angle whose measure you are given or need to find and for the sides you are given lengths or whose sides you need to find.
Given:
side AB = 10 cm
m<C = 25°
Find:
side AC
The angle of interest here is <C whose measure is 25°.
Now look at the given side and the side you are looking for with respect to angle C, the given angle.
For angle C, AC is the adjacent leg.
For angle C, AB is the opposite leg.
Which trig function relates the opposite leg to the adjacent leg?
It is the tangent, since, in general, tan X = opp/adj.
tan C = opp/adj
tan 25° = AB/AB
tan 25° = 10 cm/b
Solve for b.
b × tan 25° = 10 cm
b = 10 cm / tan 25°
Using your calculator, divide 10 by the tangent of 25°.
b = 21.44506...
Answer: b = 21
Answer:
[tex]b = \bf 21 \space\ cm[/tex]
Step-by-step explanation:
• To solve for a side using SOH CAH TOA, first check the angle whose measure is given.
In this case, we know ∠ C is 25°.
• Next we have to figure out the relationships between the given angle and two sides: one side whose length we know, and the other whose length we have to find.
In this case, the side opposite to ∠ C is known to be 10 cm, and the side adjacent to ∠ C is AC, whose length, b, we have to find.
• The trigonometric ratio that relates the adjacent and opposite sides of an angle is tan, where:
[tex]\boxed{tan \theta = \frac{opposite}{adjacent} }[/tex] .
We can use this relationship to calculate the value of b:
⇒ [tex]tan (25 \textdegree) = \frac{10}{b}[/tex]
Solving for b:
⇒ [tex]b \cdot tan (25 \textdegree) = 10[/tex]
⇒ [tex]b = \frac{10}{tan (25 \textdegree)}[/tex]
⇒ [tex]b = 21.45[/tex]
⇒ [tex]b \approx \bf 21 \space\ cm[/tex] (rounded to the nearest whole number)
