The length of the line is 1712.12 miles if there were often long lines of cars waiting at gas stations. If there were a million cars in line, bumper to bumper.
Given :
What is average?
It is defined as the single number that represents the mean value for the given set of data or the closed value for each entry given in the set of data.
There were often long lines of cars waiting at gas stations. If there were a million cars in line, bumper to bumper.
The average length = 9.04 feet
The length of the line can be found as follows:
= 9.04 * 1,000,000
The length of the line = 9,040,000 feet/5280 feet (1 mile)
= 1712.12 miles
Thus, the length of the line is 1712.12 miles if there were often long lines of cars waiting at gas stations. If there were a million cars in line, bumper to bumper.

Our school band is selling sweatshirts and t
shirts to raise money. The goal is to raise
$1200. The sweat shirts cost $12.50 and will
be sold for $15. The shirts will cost $6.50
and be sold for $8.
a) Write a function to describe the
number of shirts and sweatshirts the band can sell to reach their profit goal.
Explain your reasoning.
Evaluate:
Σ18/1 (5n– 4) = [? ]
Basically, you are going to evaluate 5n - 4 from n = 1 to n = 18. Don't forget to add as you evaluate.
I will get you started.
Let n = 1 and then n = 2.
5(1) - 4 + 5(2) - 4 + the rest
5 - 4 + 10 - 4 + the rest
1 + 6 + the rest
7 + the rest
Just continue the pattern. You will then let n be 3, 4, 5, etc all the way to 18.

Answer:
∠A = 6x + 4
Step-by-step explanation:
Hello There!
We are given the exterior angle ∠ACD and an interior angle ∠B
If you didn't know this is the rule for exterior angles of a triangle:
An exterior angle is equal to the sum of its opposite interior angles
so ∠ACD = ∠A + ∠B ( ∠A and ∠B being the opposite interior angles)
So with the information that we are given we plug them into their corresponding angle
then we would have
8x+5 = ∠A + 2x + 1
now we solve for A
Well how do we solve for A?
Well we have to isolate the variable
To do so we want to get rid of 2x + 1
We do that by subtract each side by 2x and 1
8x + 5 - (2x + 1 ) = 6x + 4
we're left with
∠A = 6x + 4
The sum of two numbers is 52 . The larger number is 2 less than twice the smaller number .What are the numbers
Answer:
35.34 and 16.66
Step-by-step explanation:
Given data
let the numbers be x and y
the smaller number = x
the larger number = y
x+y=52--------1
The larger number is 2 less than twice the smaller number
y=2x-2-------2
put y= 2x-2 in eqn 1
x+2x-2=52
3x-2=52
3x=52-2
3x=50
x= 50/3
x= 16.66
put x=16.66 in eqn 1 to find y
x+y=52
16.66+y= 52
y=52-16.66
y= 35.34
Hence the numbers are
35.34 and 16.66
Check
35.34+16.66= 52

A tablet and a digital camcorder are both on sale for 30% off. The regular price of the tablet is $185. The regular price of the camcorder is $140. What is the sale price of the tablet. A tablet and a digital camcorder are both on sale for 30% off. The regular price of the tablet is $185. The regular price of the camcorder is $140. What is the sale price of the tablet.
Answer:
$98
Step-by-step explanation:
Tablet
Divide 185 by 10 to get 18.5, this is 10% of the price.
Since it is 30% off, it is 70% of the price.
Multiply 18.5 by 7 to get the sale price, $129.50
Camcorder
Divide 140 by 10 to get 14, this is 10% of the price.
Since it is 30% off, it is 70% of the price.
Multiply 14 by 7 to get the sale price, $98

Someone help:
1 Asalesman leaves home at 0800 and travels for 13 hours at an average
speed of 60km/h. He then stops for 30 minutes. He continues for 2 more
hours at 50km/h and stops for 1 hour. He then returns home and arrives
home at 1600.
a) Show this in a travel graph.
b) Calculate his average speed for his return journey.
Answer:
a) Please find attached the required travel graph with times increasing from (0:00) of the day of travel to the following day
b) The average speed of return journey = 880 km/(15.5 h) ≈ 56.77 km/h
Step-by-step explanation:
The given information includes;
The time of departure of the salesman, t₁ = 0800
The duration of travel of the salesman = 13 hours
The average speed with which the salesman travels = 60 km/h
The time duration in which he stops = 30 minutes
The speed with which he continues = 50 km/h
The time duration he travels at 50 km/h = 2 hours
The time he arrives home after he turns, t₂ = 16:00
The appropriate graph is a distance time graph
So as to show the given information in a travel graph, we calculate the distances as follows;
Time [tex]{}[/tex] Location
08:00 [tex]{}[/tex] 0
08:00 + 13 = 21:00 [tex]{}[/tex] 13 × 60 = 780
21:00 + 0.30 = 21:30 [tex]{}[/tex] 780
21:30 + 2:00 = 23:30 [tex]{}[/tex] 780 + 50 × 2 = 880
23:30 + 1:00 = 0:30 (24: hours ) [tex]{}[/tex] 880
16:00 [tex]{}[/tex](40 hours from 0:00 the previous day)
Therefore, we have;
Location; 0, 780, 780, 880, 880, 0
Time; 08:00, 21:00, 21:30, 23:30, 24:30, 40:00
To show the distance traveled over the given time periods graphically, we let 00:30 = 24.30 and the arrival time (the next day) 16:00 = 40.00 hours after midnight (0:00) the previous day
Please find attached the required travel graph created with Microsoft Excel
b) The average speed of return journey = (Total distance of return journey)/(Total time)
The total distance going = 880 km
Therefore the return journey is also 880 km
∴ The total time taken on return journey Δt = (Time at arrival home) - (Time of start of return journey)
∴ Δt = 40 - 24.5 = 15.5
Δt = 15.5 hour
∴ The average speed of return journey = 880 km/(15.5 h) ≈ 56.77 km/h.

Step-by-step explanation:
[tex] \huge \frac{ {9}^{ \frac{1}{2}b } }{ {3}^{a} } \\ \\ = \huge \frac{ {( {3}^{2} )}^{ \frac{1}{2}b } }{ {3}^{a} } \\ \\ = \huge \frac{ { {3}}^{2 \times \frac{1}{2}b } }{ {3}^{a} } \\ \\ \huge = \frac{ {3}^{b} }{ {3}^{a} } \\ \\ \huge = \frac{1}{ {3}^{a - b} } \\ \\ \huge= \frac{1}{ {3}^{2} } \\ ( \because \: a - b = 2)\\ \\ \huge = \frac{1}{ 9 }[/tex]
The evaluation of the expression 9^((1/2)b)/3^a is 1/9
What are some basic properties of exponentiation?If we have a^b then 'a' is called base and 'b' is called power or exponent and we call it "a is raised to the power b" (this statement might change from text to text slightly).
Exponentiation(the process of raising some number to some power) have some basic rules as:
[tex]a^{-b} = \dfrac{1}{a^b}\\\\a^0 = 1 (a \neq 0)\\\\a^1 = a\\\\(a^b)^c = a^{b \times c}\\\\ a^b \times a^c = a^{b+c} \\\\^n\sqrt{a} = a^{1/n} \\\\(ab)^c = a^c \times b^c\\\\a^b = a^b \implies b= c \: \text{ (if a, b and c are real numbers and } a \neq 1 \: and \: a \neq -1 )[/tex]
Now, for this case, we are given that:
a - b = 2
The expression is:
[tex]\dfrac{9^\dfrac{1}{2}b}{3^a}[/tex]
Since we know that [tex]3^2 = 9[/tex], thus:
[tex]\dfrac{9^{\frac{1}{2}b}}{3^a} = \dfrac{(3^2)^{\frac{1}{2}b}}{3^a} = \dfrac{3^{2 \times 1/2 \times b}}{3^a} = \dfrac{3^b}{3^a} = \dfrac{1}{3^{a-b}}[/tex]
Since a-b = 2, therefore, we get:
[tex]\dfrac{9^{\frac{1}{2}b}}{3^a} =\dfrac{1}{3^{a-b}} = \dfrac{1}{3^2}} = \dfrac{1}{9}[/tex]
Thus, the evaluation of the expression 9^((1/2)b)/3^a is 1/9

What is the domain and range for function A?
Answer:
Domain → (-∞, ∞)
Range → (-∞, 5)
Step-by-step explanation:
Domain of a function is a set of x-values (input values) for which the function is defined.
Function A is a quadratic function (in the form of a parabola) opening downwards.
This function is defined for every input value from negative infinity to positive infinity.
Therefore, domain of the given function A is (-∞, ∞).
Similarly, y-values (output values) vary from negative infinity to 5.
Therefore, range of the given quadratic function will be (-∞, 5).

If C = q^2-2+q and D = 3q^2+2q, find an expression that equals 3C - 3D in standard form.
Please help ;-;
Answer:
- 9q² - 3q - 6
Step-by-step explanation:
3C - 3D
= 3(q² - 2 + q) - 3(3q² + 2q) ← distribute parenthesis
= 3q² - 6 + 3q - 9q² - 6q ← collect like terms
= - 9q² - 3q - 6
The required expression is - 9q² - 3q - 6 which equals 3C - 3D in standard form.
What is the expression?Expressions are defined as mathematical statements that have a minimum of two terms containing variables or numbers.
The expression is given in the question as follows:
3C - 3D ....(i)
We have to determine the resultant expression that could represent the standard form.
As per the question, we have the equations
C = q² - 2 + q and D = 3q² + 2q
Substitute these equations into the expression (i):
3(q² - 2 + q) - 3(3q² + 2q)
Apply the distributive property of multiplication,
3q² - 6 + 3q - 9q² - 6q
Combine the likewise terms in the above expression,
- 9q² - 3q - 6
Thus, the resultant expression is - 9q² - 3q - 6.
