200 rides does it take to break even.
What are the many sorts of cost?
Fixed and variable costs are the two main categories of expenses incurred by enterprises. While variable costs fluctuate with output, fixed costs do not.
Sometimes, fixed costs are referred to as overhead costs. They must be paid whether a company produces 100 or 1,000 widgets.
The cost function is given by
C(x ) = 15x + 1000
It is also given that it costs $25 per ride.
so,
Revenue function for x number of rides be
R(x) = 20x
For break even:-
The cost must be equal to the Revenue i.,e
C(x) = R(x)
15x + 1000 = 20x
1000 = 20x - 15x
1000 = 5x
x = 1000/5
x = 200
Therefore, 200 rides does it take to break even.

Venus: 1.08 x 108 kilometers
Mercury: 5.79 × 107 kilometers
How much closer to the sun is Mercury?
Express your answer using scientific
notation.
The subtraction of significant figures between the distance is 5.01 × 10⁷km
SubtractionIn this problem, we have to subtract the difference between the distance of Venus and Mercury. When subtracting significant digits, the amount of significant digits that will be in the final answer is determined by the number of significant digits present after the decimal place in the numbers we are subtracting.
The distance between Venus and Mercury can be calculated as
1.08 × 10⁸ - 5.79 × 10⁷ = 50,100,000km
To express the value in significant figures, we will have
50,100,000 = 5.01 × 10⁷km

write a polynomial function for each set of zeros
[tex]x = \sqrt{2} [/tex]
[tex] - i[/tex]
The required polynomial function is f(x) = (x + i)² which is degree 2 with the zeros x = √2 and x = -i.
We have to determine a polynomial function for each set of zeros:
x = √2, -i
To write a polynomial function with the zeros x = √2 and x = -i, we can start by setting the function equal to zero and substituting in the zeros:
f(√2) = 0
f(-i) = 0
We can then solve for the coefficients by expressing the polynomial function in terms of (x - √2) and (x + i).
For example, we can write:
f(x) = (x - √2)(x + i)q(x)
for some polynomial q(x).
Substituting in the zeros, we get:
f(√2) = (√2 - √2)(√2 + i)q(√2) = 0
f(-i) = (-i - √2)(-i + i)q(-i) = 0
Solving for q(x), we find:
q(x) = (x + i)/(x - √2)
Substituting this back into the original equation, we get:
f(x) = (x - √2)(x + i)(x + i)/(x - √2)
f(x) = (x + i)²
This is a polynomial function of degree 2 with the zeros x = √2 and x = -i.

The 4th proportional of the given ratio is 4/3. option C
The range of the data 112, 121, 184, 189, 177, 190 is 78. option A
How to find 4th proportional?It follows from the concept of proportions that the ratios can be represented as follows;
21 : 7 = 4 : 3a + 1
21/7 = 4 / (3a + 1)
cross product
21 × (3a + 1) = 4 × 7
63a + 21 = 28
subtract 21 from both sides
63a = 28 - 21
63a = 7
a = 7/63
a = 1/9
So,
3a + 1
= 3(1/9) + 1
= 3/9 + 1
= 1/3 + 1
= 1 ⅓
= 4/3
21 : 7 = 4 : 4/3
Range of the data:
112, 121, 184, 189, 177, 190
Recall, the range of a dataset is the difference between the maximum and minimum data values and hence, we have;
Range = Highest data value - Lowest data value
= 190 - 112
= 78
Therefore, the range of the given set of data is 78.

-Wilson Middle School wants to rent tables for their weeklong art festival. One rental company charges a $20 setup
fee and $12 per table for the week. Another rental company charges a $30 setup fee and $10 per table for the week.
How many tables can the school rent for the charge to be the same for both companies?
Answer:
5 tables
Step-by-step explanation:
Let x be the number of tables the school needs to rent, and c be the total cost of renting the tables.
We can use the following equation to represent the cost of renting from the first company:
c = 20 + 12x
And we can use the following equation to represent the cost of renting from the second company:
c = 30 + 10x
As c is the same constant in both equations, we can say the following:
20 + 12x = 30 + 10x
Now we can solve this equation by simplifying:
20 + 12x = 30 + 10x
20 + 2x = 30
2x = 10
x = 5
Therefore, the school will need to rent 5 tables for the cost to be the same from both renting companies.
Answer: 5 tables
Step-by-step explanation:
The first rental company will charge $32 for one table.
The second rental company will charge $40 for one table.
So if we make a table, and keep adding $12 to the first company and $10 to the second it will look like this.
First company Second company Table
$32 $40 1
$44 $50 2
$56 $60 3
$68 $70 4
$80 $80 5
Therefore, the school can rent 5 tables for the same price in both companies.

Sam wants to purchase birthday gifts for his two sisters that share the same birthday. One sister likes daisies which cost $2 per stem and the other likes tulips which cost $3 per stem. 1). If he has $12 to spend, how many of each could he buy?
You must write an inequality.
2). Graph your solution
The inequality which represents is 2x + 3y ≤ 12 where x is the number of daisies and y is the number of tulips.
What is inequality?A mathematical phrase in which the sides are not equal is referred to as being unequal. In essence, a comparison of any two values reveals whether one is less than, larger than, or equal to the value on the opposite side of the equation.
Suppose the cost of one daisy is x while the cost of one tulip is y.
2x + 3y will be totally spent and it can be almost $12.
2x + 3y ≤ 12
Hence "The inequality which represents is 2x + 3y ≤ 12 where x is the number of daisies and y is the number of tulips.".

P(Picking one Green Hat and Something Else)=
P(Picking one Blue Hat and Something Else)=
P(Picking one Red Hat and Something Else)=
p(Picking one Brown hat and something Else)=
Add the probabilities together to answer the question
The probability that both hats are different colors is; 0.7425
How to find the probability of selection?We are given;
Total number of hats = 30 hats
Number of green hats = 5 hats
Number of blue hats = 7 hats
Number of red hats = 12 hats
Number of brown hats = 6 hats
Now, if Mary selects two hats at random, then the probability that they are different colors is;
P(they are different colors) = 1 - P(both are the same color)
P(both are the same color) = (⁵/₃₀ * ⁴/₂₉) + (⁷/₃₀ * ⁶/₂₉) + (¹²/₃₀ * ¹¹/₂₉) + ( ⁶/₃₀ * ⁵/₂₉)
= (20 + 42 + 132 + 30)/(30*29)
= 224/(30*29)

Answer:
B: 3(x-6) = 3x-18

The left and right sides of this equation are actually equal! We can see this by dividing the 3 on the left through the parentheses. This gives us [tex]3x-18[/tex], which is equal to the right-hand side of the equation!
To solidify this, we add 18 to both sides, and subtract 3x from both sides, which gives us that 0=0, so there are infinitely many solutions for x(since no matter what x is, it will result in 0=0 which is always true).

The values of the expressions are x = √6, y = 2√3 and z = √2
How to evaluate the expressions?From the question, we have the following parameters that can be used in our computation:
[tex]x =\sqrt{12-3\sqrt{7} } - \sqrt{12 + 3\sqrt{7} }[/tex]
[tex]y = \sqrt{7-4\sqrt{3 } } - \sqrt{7 + 4\sqrt{3} }[/tex]
[tex]z = \sqrt{2 + \sqrt{3} } - \sqrt{2 - \sqrt{3} }[/tex]
We have
[tex]x =\sqrt{12-3\sqrt{7} } - \sqrt{12 + 3\sqrt{7} }[/tex]
Take the square of both sides
So, we have
[tex]x^2 =12-3\sqrt{7} + 12 + 3\sqrt{7} - 2(\sqrt{12-3\sqrt{7} } * \sqrt{12 + 3\sqrt{7} })[/tex]
This gives
x² = 12 - 3√7 + 12 + 3√7 - 2√81
Evaluate the roots
So, we have
x² = 12 - 3√7 + 12 + 3√7 - 18
Evaluate the sum and the difference
x² = 6
Take the square roots of both sides
x = √6
Using the same steps above, we have
[tex]y = \sqrt{7-4\sqrt{3 } } - \sqrt{7 + 4\sqrt{3} }[/tex]
Square both sides
So, we have
[tex]y^2 = 7 - 4\sqrt 3 + 7 + 4\sqrt 3 - 2 * \sqrt{7-4\sqrt{3 } } * \sqrt{7 + 4\sqrt{3} }[/tex]
This gives
[tex]y^2 = 7 - 4\sqrt 3 + 7 + 4\sqrt 3 - 2 * 1[/tex]
Evaluate
y² = 12
Take the square root of both sides
y = 2√3
Lastly, we have
[tex]z = \sqrt{2 + \sqrt{3} } - \sqrt{2 - \sqrt{3} }[/tex]
Square both sides
[tex]z^2 = 2 + \sqrt 3 + 2- \sqrt 3 - 2 * \sqrt{2 + \sqrt{3} } * \sqrt{2 - \sqrt{3} }[/tex]
This gives
