Which statement best describes the domain of the function represented in the graph?
3 ≤ x ≤ 12 or x is between 3 and 12, inclusive
3 ≤ x ≤ 7 or x is between 3 and 7, inclusive
2 ≤ x ≤ 12 or x is between 2 and 12, inclusive
2 ≤ x ≤ 7 or x is between 2 and 7, inclusive
Answers
The most accurate statement is 2 ≤ x ≤ 12 or x is between 2 and 12, inclusive.
The statement that best describes the domain of the function represented in the graph is 2 ≤ x ≤ 12 or x is between 2 and 12, inclusive.
The domain of a function refers to all the possible input values (in this case, the quantity of blue paint) for which the function produces an output (the quantity of red paint).
Looking at the graph, we can see that the line segment starts at a blue paint quantity of 2 and ends at a blue paint quantity of 12.
Since the endpoints are included in the line segment, we know that the function is defined for all blue paint quantities between 2 and 12, inclusive.
Therefore, the most accurate statement is 2 ≤ x ≤ 12 or x is between 2 and 12, inclusive.

Answers
If you don't know why 3 represents the initial fee picture this. You get into the taxi and have not traveled any miles, but instead of starting out at zero, the money meter shows $3.00. The cost of every mile you travel is added to the initial $3.00.

Hannah says that 2.11 is a rational number. Gus says that 2.11 is a repeating decimal.
Answers
Answer:
Yes, she is correct.
Step-by-step explanation:
A real number that can be expressed as [tex]\frac{p}{q}[/tex],
Where,
p and q are integers,
Such that, q ≠ 0,
is called a rational number.
A terminating decimal is always a rational number,
Thus, 2.11 is a rational number,
Verification :
2.11 = [tex]\frac{211}{100}[/tex]
Where,
Both 211 and 100 are integers,
Such that 100 ≠ 0.
The value 2.11 is a rational number and not a repeating decimal.
Given the number 2.11 ;
Rational numbers Can be expressed in the form p/q ; where q ≠ 0. However, irrational numbers cannot be be expressed in the form p/q. 2.11 is written into two decimal places ; therefore it can be expressed thus ;(2.11 × 100) ÷ 100 [tex] \frac{211}{100} [/tex][tex]since \: 2.11 = \frac{211}{100} [/tex]
Then, we can conclude that 2.11 is a rational number

The budget for a film production includes the following employee pay scales: $15,000 for each technical crew member (e.g. camera, lighting, sound), and $10,000 for each support staff (e.g., drivers, craft services, production assistants). A minimum of 20 employees is needed, but the locations can accommodate a maximum of 50 people. There must be at least 12 technical crew members to shoot the film, and there must be at least half as many crew members as support staff. Which combination of employees will minimize the cost, and what is the minimum feasible cost?
Answers
Final answer:
The minimum cost combination of film production employees is 12 technical crew members and 24 support staff members, with a minimum feasible cost of $420,000.
Explanation:
To determine the combination of employees that will minimize the cost, let's set up variables for technical crew members (T) and support staff members (S).
The pay scales are $15,000 for each technical crew member (T) and $10,000 for each support staff member (S).
The objective is to minimize the cost C, where C = 15,000T + 10,000S.
From the constraints provided:
There must be a minimum of 20 employees: T + S ≥ 20.The maximum number of people that can be employed is 50: T + S ≤ 50.There must be at least 12 technical crew members: T ≥ 12.There must be at least half as many crew members as support staff: T ≥ 0.5S.To minimize the cost while satisfying all constraints, we should aim to hire as few technical crew members as possible, given they are more expensive.
If T = 12 (the minimum), we can solve for S using T ≥ 0.5S, which gives us S ≥ 24.
However, S must be even due to the constraint T ≥ 0.5S and hence we can set S = 24 as a candidate solution, resulting in the minimum number of employees (12 + 24 = 36).
We also need to ensure that S ≤ 2T to satisfy the condition T ≥ 0.5S; with T = 12, the maximum S can be is 24.
The minimum feasible cost is determined by plugging T = 12 and S = 24 into the cost equation:
C = 15,000(12) + 10,000(24) = 180,000 + 240,000 = $420,000.

x/6-x/7=ab
Answers
To solve x/6 - x/7 = ab, find the common denominator, simplify, and then isolate x by multiplying both sides of the equation by the common denominator. The solution is x = 42ab. Always check your answer to ensure it satisfies the original equation.
Explanation:To solve the equation x/6 - x/7 = ab, one must find a common denominator for the fractions. In this case, the common denominator is 42 because 6 and 7 are both factors of 42. By converting both fractions to have the denominator of 42, we have:(7x/42) - (6x/42) = ab
This simplifies to x/42 = ab, since 7x - 6x is x. Now, multiply both sides by 42 to get x = 42ab.
If we want to solve the equation for a variable other than x, such as y, we might need to return b to denominator status, which implies that we need to divide both sides by b if b represents a multiplication factor for y.
It's also important to confirm that our manipulations haven't altered the value of the equation, which can be done by checking the answer at the end to ensure it is reasonable and satisfies the original equation.

On the first day of school, the school bookstore sold 348 notebooks, some at 25¢ each and the rest at 38¢ each. The total amount of money paid for the notebooks was $100.91. How many of each kind were sold?
Answers
Final answer:
The bookstore sold 107 notebooks at 38¢ each and 241 notebooks at 25¢ each. A system of equations was used to determine the number of each notebook sold.
Explanation:
Let's denote the number of notebooks sold at 25¢ each as [tex]x[/tex] and the number of notebooks sold at 38¢ each as [tex]y[/tex] .
We are given two pieces of information:
The total number of notebooks sold is [tex]348: x + y = 348[/tex]The total amount of money collected is [tex]$100.91: 0.25x + 0.38y = 100.91[/tex]We can set up a system of two equations to represent this information:
[tex]x+ y = 348[/tex] (Equation 1)
[tex]0.25x + 0.38y = 100.91[/tex] (Equation 2)
Now, we can solve this system of equations to find the values of x and y.
Multiply Equation 1 by 0.25 to make the coefficients of x in both equations the same:
[tex]0.25x + 0.25y = 87[/tex] (Equation 3)
Now, subtract Equation 3 from Equation 2 to eliminate [tex]x[/tex] :
[tex]( 0.25x + 0.38y ) - ( 0.25x +0.25 y) = 100.91 - 87[/tex]
[tex]0.13 y = 13.91[/tex]
[tex]y = 107[/tex]
Now that we have the value for y, substitute it back into Equation 1 to find x:
[tex]x + 107 = 348[/tex]
[tex]x = 241[/tex]
Hence , the solution is x = 241 and y = 107, meaning 241 notebooks were sold at 25¢ each and 107 notebooks were sold at 38¢ each.
Jen ran 1 2/3 miles in 1/4 of an hour, and Max ran 1 1/2 miles in 1 /5 of an hour. What is the average speed of each of Jen and Max? Who runs faster?
Answers
Jen: 1 2/3 = 5/3 *4 = 20/3 = 6 2/3 miles per hour
Max: 1 1/2 = 3/2 * 5 = 15/2 = 7 1/2 miles per hour
Max runs faster
Answer:
Max runs faster than Jen.
Average speed = 7.085 Miles per Hour
Step-by-step explanation:
Distance covered by Jen = [tex]1\frac{2}{3} = \frac{5}{3} \text{ miles}[/tex]
Time taken by Jen = [tex]\frac{1}{4}\text{ hours}[/tex]
Distance covered by Max = [tex]1\frac{1}{2} = \frac{3}{2} \text{ miles}[/tex]
Time taken by Jen = [tex]\frac{1}{5}\text{ hours}[/tex]
Formula:
[tex]Speed = \displaystyle\frac{Distance}{Time}[/tex]
Speed of Jen = [tex]\displaystyle\frac{\frac{5}{3} }{\frac{1}{4} } = \frac{20}{3} = 6.67 \text{ miles per hour}[/tex]
Speed of Max = [tex]\displaystyle\frac{\frac{3}{2} }{\frac{1}{5} } = \frac{15}{2} = 7.5 \text{ miles per hour}[/tex]
Hence, Max runs faster than Jen.
Average speed:
[tex]\displaystyle\frac{\text{Speed of Max + Speed of Jen}}{2} \\\\= \dsplaystyle\frac{6.67 + 7.5}{2} = 7.085\text{ Miles per Hour}[/tex]

Brandon rode his bike 90% of the distance that Carlee did this week. He rode 58.5 miles. How many miles did Carlee ride?
Answers
To find out how many miles Carlee rode, you need to divide the distance Brandon rode (58.5 miles) by 0.9 (representing 90%). The result is that Carlee rode 65 miles.
Explanation:The problem requires you to determine the distance that Carlee biked based on the information provided. Given that Brandon rode his bike 90% of the distance Carlee did, and he rode 58.5 miles, to calculate the distance Carlee traveled, you would divide the distance Brandon rode by 0.9 (which represents 90%).
So, the calculation would be: 58.5 ÷ 0.9 = 65.
Therefore, Carlee must have biked 65 miles in total given the information provided.
