Answer:
1. Variables:
x is the profit
y is the number of customers
z is the number of times the shuttle driver must fill up the tank
2. 10y-45z ≥ 6,000
Step-by-step explanation:
The variables for unknown values are:
x is the profit
y is the number of customers
z is the number of times the shuttle driver must fill up the tank
According to the statement, the company wants to make profits of at least $6,000 and the profits are equal to the total sales minus the costs.
Sales= Price per customer*number of customers= 10x
Costs= Price per each time the tank must be filled*number of times the shuttle driver must fill up the tank= 45y
z=10y-45z where z[tex]\geq[/tex] 6,000
This means that 10y-45z[tex]\geq[/tex] 6,000.

What is 5d - 10 = 20
Answer:
d = 6
Step-by-step explanation:
5d - 10 = 20
Add 10 to each side
5d - 10+10 = 20+10
5d = 30
Divide by 5
5d/5 = 30/5
d = 6
Answer:
d = 6
Step-by-step explanation:
5d - 10 = 20
Add 10 to both sides of the equation
5d = 30
Divide both sides of the equation by 5
d = 6

the common ratio of a g.p is 3. given that the 5th term is greater than the first term by 400 what is the fifth term of the g.p.
Answer:
405.
Step-by-step explanation:
First term = a1
5th tern = a1 r^4
So a1r^4 - a1 = 400 r = 3 so:
3^4 * a1 - a1 = 400
a1(81-1) = 400
80a1 = 400
a = 5
Therefore the fifth term = 5* 3^4
= 405.
The first term and fifth term of Geometric progression will be 5 and 405, respectively.
What is a geometric sequence?Let a₁ be the first term and r be the common ratio.
Then the nth term of the geometric sequence is given as,
aₙ = a₁ · (r)ⁿ⁻¹
The common ratio of a g.p is 3. given that the 5th term is greater than the first term by 400. Then the equation is given as,
a₅ - a₁ = 400 ...1
a₅ = a₁ · 3⁴ ...2
From equations 1 and 2, then we have
81a₁ - a₁ = 400
80a₁ = 400
a₁ = 5
Then the value of the fifth term is given as,
a₅ = a₁ · 3⁴
a₅ = 5 x 81
a₅ = 405
The first term and fifth term of Geometric progression will be 5 and 405, respectively.

based on the function h(t), what will be the account value five years after the account is opened?
Answer:
Option B
Step-by-step explanation:
f(t) = 5000
g(t) = 250t
h(t) = f(t) + g(t) = 5000 + 250t
After 5 years, the amount of money in the account is:
h(t = 5) = 5000 + 250(5) = 5000 + 1250 = 6250$

If a sixth skateboard is added to the sample that has a price of $450, what
happens to the standard deviation?
Answer:
standard deviation=143.527

Answer:
B. -1/3x
Step-by-step explanation:
Start with
y = mx + b
The y-intercept is 0, so we have
y = mx
To find m, the slope, start at (0, 0).
slope = m = rise/run
Go up 1 unit and left 3 units. Rise = 1; run = -3.
m = 1/(-3) = -1/3
Now we have

In a school auditorium, the number of chairs in a row is the same as the number of rows of chairs. There are 7033 students in the school. If we know that less than 31 chairs were empty, how many chairs were empty after all the students sat down?
Same number of rows to chairs in a row would form a square.
Use the total number of students as the area
Find the number or rows by taking the square root of student:
The square root of 7033 is 83.86
Round up to 84
Total seats would be rows x seats per row:
84 x 84 = 7,056 total seats
7056 seats - 7033 students = 23 empty seats

Find the measures of two angles, one positive and one negative, that are coterminal with pi divided by ten . (2 points) twenty-one pi divided by ten ; negative pi divided by ten eleven pi divided by ten ; negative nine divided by ten twenty-one pi div
Answer:
The two angles coterminal with π/10 are 21π/10 and -19π/10
Step-by-step explanation:
To find a two angles that are coterminal with π/10, we add and subtract 360°(that is 2π) from π/10.
So, the first angle coterminal with π/10 is
A = π/10 + 2π
taking the L.C.M which is 10, we have
A = (π + 20π)/10
A = 21π/10
The second angle coterminal with π/10 is
B = π/10 - 2π
taking the L.C.M which is 10, we have
B = (π - 20π)/10
B = -19π/10
So the two angles coterminal with π/10 are 21π/10 and -19π/10

So for this question :
[tex] {(5x + 7)}^{2} \\ = {(5x)}^{2} + 2(5x)(7) + {(7)}^{2} \\ = 25 {x}^{2} + 70x + 49[/tex]
Answer:
B. 25x^2+70x+49
Step-by-step explanation:
To multiply we can use a method called FOIL. In this method, we multiply the first terms of each binomial, then the outer terms (first and last), then the inner terms (2nd and 3rd), and finally the last terms (2nd and last). The two binomials in this case are (5x+7)(5x+7).
So this means we first multiply 5x*5x, then 5x*7, then 7*5x, and finally 7*7. Multiplying these out we get 25x^2 + 35x + 35x +49. Finally, combining like terms we get 25x^2+70x+49, which is our answer.

Answer:
Third option is correct.
Step-by-step explanation:
Take a closer look at the box plot given in the question. The range of the values represented in the box plot is starts from where the whiskers begins from our left, and where the whiskers to our right ends. The range of values of the points awarded ranges from 0 - 100, as represented on the box plox. Also,the median is indicated by the vertical line that divides the rectangular box into two. The median point = 70.
Now, examine all the dot plots given as options. The dot plot that has a range of 0 - 100, and a median of 70, is the dot plot that best represents the box plot.
Thus, the third option among the answer choices given would be out answer. The third option shows a dot plot with range of values of points from 0 - 100, and also a median of 70 points.

What is Equation?Two or more expressions with an Equal sign is called as Equation.
We need to find two numbers whose product is 1/4 and add to -1.
Let the two numbers are x and y.
By given,
Two numbers multiply to 1/4
xy=1/4
Two numbers add to -1
x+y=-1
Let x=-y-1
Substitute in equation 1.
(-y-1)y=1/4
-y²-y-1/4=0
Multiply negative on both sides
y²+y+1/4=0
Use quadratic formula
b=1,c=1/4,a=1
y=-1±√1-1/2=-1/2
Now substitute y in x+y=-1
x-1/2=-1
x=-1+1/2
x=-1/2
Hence the two numbers are x =-1/2 and y=-1/2 whose product is 1/4 and which add to -1.
