Answer:
n = 10
Step-by-step explanation:
Step 1: Translate word to math
"product" = multiplication
"3" = 3
"difference" = subtraction
"a number n" = n
"4" = 4
"is" means equal
"eighteen" = 18
Step 2: Combine/set up equation
3(n - 4) = 18
Step 3: Solve for n
Distribute 3: 3n - 12 = 18Add 12 to both sides: 3n = 30Divide by 3 on both sides: n = 10Answer:
Equation: 3(n - 4) = 18Solved: n = 10Step-by-step explanation:
To solve:
Apply the distributed property: 3n - 12 = 18Add 12 to each side, so it now looks like this: 3n = 30Divide each side by 3 to cancel out the 3 next to n. It should now look like this: n = 10I hope this helps!

The average price of a movie ticket in the United States from 1980 to 2000 can be modeled by the expression 2.75+0.10x, where x is the number of years since 1980.
Which part of the expression corresponds to the cost of movie tickets in 1980?
Answer:
2.75
Step-by-step explanation:
0.10 represents the rate at which prices have increased since 1980..
2.75 represents the price in 1980
This can be confirmed by inputting 0 as the value of x.
2.75+0.10(0) = 2.75

The length of a rectangle is 2 less than two times the width. Perimeter is 42. Find the length and the width.
Answer:
Hi there
Your answer is
width= 5.75
length= 9.5
Step-by-step explanation:
L=2w-2
P=42
Perimeter formula
L+L+W+W=P
(2w-2)+(2w-2)+w+w=42
8w-4=42
+4
8w=46
/8
w= 5.75
Plug in width in length formula!
L=2w-2
L=2(5.75)-2
L=9.5

An ordered pair is written as:
(domain, range)
(range, domain)
Answer:
the answer is (domain, range) or (x,y)
An ordered pair is written as, (domain, range). So Option A is correct
What is Domain and Range ?The domain of a function is the set of all input values (independent variable) for which the function is defined and produces a valid output (dependent variable).
The range of a function is the set of all possible output values of the function. It represents the set of all possible values of the dependent variable.
The set of all "x" values constitutes the domain, and the set of all "y" values constitutes the range, in a set of ordered pairs.
You should keep in mind that ordered pairs are represented by the following symbols: (x, y).
Find the domain when examining a collection of ordered pairs by compiling a list of all the relation's x values.

The decibel level of a normal conversation, which has an intensity of 3.2x10-6 watts/m2, is (ANSWER1) dB. If the decibel level goes up to
80, the intensity of the sound will be
(ANSWER2) watts/m2
B = 10103(t.), where is the sound level in decibels, is the intensity of sound you are measuring, and I is the
Use the formula
smallest sound intensity that can be heard by the human ear (roughly equal to 1x10-12 watts/m2).
Answer:
The intensity of sound in decibel is 65 dB
The intensity of sound in Watts/m² is 1 x 10⁻⁴ W/m²
Step-by-step explanation:
The intensity of sound in decibel is given by;
[tex]\beta (dB) = 10Log(\frac{I}{I_o})\\\\[/tex]
where;
I₀ is the smallest sound intensity that can be heard by the human ear = 1 x 10⁻¹² watts/m²
[tex]\beta (dB) = 10Log(\frac{I}{I_o})\\\\\beta (dB) = 10Log(\frac{3.2*10^{-6}}{1*10^{-12}})\\\\\beta (dB) = 65.05 \ dB[/tex]
= 65 dB
If the decibel level goes up to 80 dB, the intensity in W/m² is given by;
[tex]\beta (dB) = 10Log(\frac{I}{I_o} )\\\\80 = 10Log(\frac{I}{I_o} )\\\\8 =Log (\frac{I}{I_o} )\\\\10^8 = \frac{I}{I_o} \\\\I = I_o *10^8\\\\I = 1*10^{-12}*10^8\\\\I = 1*10^{-4} \ W/m^2[/tex]

The two lines intersected by the transversal are parallel. If m/1 =(8x) and m/2= (10x - 18) what is the value of x?
A.1
B.9
C.11
D.6
Answer:
x = 9
Step-by-step explanation:
Given:
m<1 = 8x
m<2 = (10x - 18)
Required:
Value of x
Solution:
<1 and <2 are alternate exterior angles. Alternate exterior angles are congruent. Therefore:
m<1 = m<2
8x = 10x - 18 (substitution)
Solve for x
8x - 10x = -18
-2x = -18
-2x/-2 = -18/-2
x = 9

The length of a rectangle is three times its width. if the perimeter of the rectangle is 48 yd, find its area.
Answer:
all the sides multiplies should equal 48
Step-by-step explanation:
sorry I don't know
The rectangle will have a 432 yd² area.
What is Area?The area is the entire amount of space occupied by a flat (2-D) surface or an object's form. On a sheet of paper, draw a square using a pencil. It has two dimensions. The area of a form on paper is the area that it occupies.
Given, The length of a rectangle is three times its width. if the perimeter of the rectangle is 48 yd
Let "l " be the length of the rectangle
thus, the width of the rectangle = l/3
Since the Perimeter of the rectangle = 48 yd
From the general formula of the Perimeter of the rectangle:
perimeter = 2*(length + width)
In our case
Perimeter = 2*( l + l/3)
Perimeter = 2*(2l/3)
Perimeter = 4L/3
Thus,
4L/3 = 48
L = 36 yd
So width = 36 /3 = 12
Since the area of the rectangle = length * width
Area = 12 * 36
Area = 432
therefore, the area of the rectangle will be 432 yd².

The Gordon family plans to buy a TV. One TV has a purchase price of $330 and an estimated yearly operating cost of $14. The other has a purchase price of $369 and an estimated yearly operating cost of $9. Which TV should the Gordons buy if they plan to keep it for 8 years? Use rational functions to help justify your answer
Answer:
Step-by-step explanation:
They should purchase the $369 one with the $9 plan.
330 + (14x8) =442
369+ (9x8) = 441
Hope this helps!
Answer:
rational functions that model the average annual cost of each television if it is owned for x years, such as f(x)= (330+14x)/x and
g(x)= (369+9x)/x
calculation proving that over 8 years, the annual cost for the $330 television is $55.25; for the $369 television, it is $55.13
