Haya , curra , and Brooke are waiting in line. Brooke is not first in line. Haya is being the oldest in line. Brooke is behind haya. List the girls in order from first to last
haya, brooke, curra is the order, i believe
To line up alphabetically by name, Brooke comes first followed by Curra, and Haya is last.
The question requires organizing the names of three girls in alphabetical order without speaking and within a time limit. Given the names are Haya, Curra, and Brooke, we can determine the alphabetical order by looking at the first letter of each name.
Brooke
Curra
Haya
To line up alphabetically by name, Brooke would be first because 'B' comes before 'C' and 'H' in the alphabet. Curra would be second since 'C' comes after 'B' but before 'H'. Finally, Haya would be last because 'H' comes after both 'B' and 'C'.

ANSWER
B. y=8x +1200
EXPLANATION
If the family's well pumps on average 8 gallons of water per minute, then the unit rate of change is 8.
This implies that, the slope of the linear equation that models this situation is
[tex]m = 8[/tex]
It was also given that, the well's tank had 1200 gallons of water in the morning.
This implies that the y-intercept of the straight line is
[tex]b = 1200[/tex]
The equation is given by:
[tex]y = mx + b[/tex]
We substitute the values to obtain:
[tex]y = 8x + 1200[/tex]
The amount of water in the tank, y after it has been pumping for x minutes is
[tex]y = 8x + 1200[/tex]

Step-by-step explanation:
A walking path is shaped like a rectangle with a width 7 times its length l. what is a simplified expression for the distance between opposite corners of the walking path?
Answer:
The simplified expression is d = (5√2) L
Step-by-step explanation:
* Lets explain the problem
- A walking path is shaped like a rectangle
- The width of the rectangle is 7 times its length L
∵ The length of the rectangle is L
∵ The width is 7 times the length
∴ The width of the rectangle is 7L
- The distance between the opposite corners represented by the
diagonal of the rectangle
- The length , the width and the diagonal formed a right triangle
- Its hypotenuse is the diagonal of the rectangle
- Its two legs are the length and the width of the rectangle
* Now we have right triangle use the Pythagoras Theorem to find
the hypotenuse
∵ The length , the width and the diagonal of the rectangle are the
sides of a right triangle
∵ The diagonal is the hypotenuse (h) of the triangle
∵ hypotenuse = √[L² + W²]
∵ The length = L and the width = 7L
∴ h = √[(L)² + (7L)²] = √[L² + 49L²] = √[50L²]
∵ √50 = 5√2
∵ √(L²) = L
∴ h = 5√2 L
∵ The diagonal of the rectangle is the distance between the
opposite corners
∴ The distance between the opposite corners is (5√2) L
* The simplified expression is d = (5√2) L, where L is the length
of the rectangle
To find the distance between opposite corners of the walking path, which is shaped like a rectangle, we need to determine the length of the diagonal.
Given that the width is 7 times the length (l), we can represent the width of the rectangle as \(7l\).
Let's denote the length of the rectangle by \(l\) and the width by \(w\). According to the information, \(w = 7l\).
Now, to find the length of the diagonal, we use the Pythagorean theorem, which states that for a right-angled triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the lengths of the other two sides.
For our rectangle, the diagonal forms the hypotenuse, and the length and width are the other two sides of the right-angled triangle. Thus, if we denote the diagonal by \(d\), the Pythagorean theorem gives us:
\(d^2 = l^2 + w^2\)
Substituting the expression for the width:
\(d^2 = l^2 + (7l)^2\)
\(d^2 = l^2 + 49l^2\)
\(d^2 = 50l^2\)
To find \(d\), we take the square root of both sides:
\(d = \sqrt{50l^2}\)
Since \(50\) can be broken down into \(25 \times 2\) and \(25\) is a perfect square, we can simplify the square root as follows:
\(d = \sqrt{25 \times 2 \times l^2}\)
\(d = \sqrt{25} \times \sqrt{2} \times \sqrt{l^2}\)
\(d = 5l \times \sqrt{2}\)
So the simplified expression for the distance between opposite corners of the walking path is:
\(d = 5l\sqrt{2}\)

Answer:
the mean absolute deviation of the data set is 2.
Step-by-step explanation:
To calculate the mean absolute deviation of a data set, we need to follow the following steps:
Step 1: Calculate the mean.
Step 2: Calculate how far away each data point is from the mean (always keeping a possitive distance).
Step 3: Calculate the mean of the deviations.
Step 1: The mean of the data set is:
Mean = (12 + 10 + 10 + 8 + 6+ 7 + 7 + 12)/8 = 72/8 = 9
Step 2:
{12 -9, 10-9, 10-9, 9-8, 9-6, 9-7, 9-7, 12-9} = {3, 1, 1, 1, 3, 2, 2, 3}
Step 3: (3 + 1 + 1 + 1 + 3 + 2 + 2 + 3)/8 = 2
In conclusion, the mean absolute deviation of the data set is 2. Which corresponds to the option B.

The probability of not getting a sum of 4 when rolling two six-sided dice is 33/36 or 92%. The probability of getting a sum greater than 5 when rolling two six-sided dice is 13/18 or approximately 72%.
Explanation:The subject area for this question is in Mathematics, specifically probability. The question asks to determine the probability of a sum not being 4, and of a sum being greater than 5 when two six-sided dice are rolled.
(a) The possibilities of getting a sum of 4 are (1,3), (2,2), and (3,1). That's 3 possibilities out of a total of 36, therefore the probability of not getting a sum of 4 is 1 - (3/36) = 33/36 (in simplified form) and as a percentage that's approximately 92%.
(b) The possibilities of getting a sum greater than 5 are (2,4),(3,3),(3,4),(4,2),(4,3),(4,4),(1,5),(2,5),(3,5),(4,5),(5,1),(5,2),(5,3),(5,4),(5,5),(1,6),(2,6),(3,6),(4,6),(5,6),(6,1),(6,2),(6,3),(6,4),(6,5), and (6,6). That's 26 possibilities out of 36, therefore the probability of getting a sum greater than 5 is 26/36 or 13/18 in simplest form, and as a percentage that's approximately 72%.
In this way, understanding of probability and how to calculate it properly can help in accurately determining outcomes in different scenarios.

The probability of the sum not being 4 is (36 - 3) / 36, and the probability of the sum being greater than 5 is 21 / 36.
Explanation:When two six-sided dice are rolled, there are 36 possible outcomes. To find the probability that the sum is not 4, we need to calculate the number of outcomes where the sum is not 4 and divide it by the total number of outcomes.
There are 3 outcomes with a sum of 4, so the probability is (36 - 3) / 36.
To find the probability that the sum is greater than 5, we need to calculate the number of outcomes where the sum is greater than 5 and divide it by the total number of outcomes.
There are 21 outcomes with a sum greater than 5, so the probability is 21 / 36.

A farmer is searching his farmland, looking for a missing horse that went grazing in the field of newly cut hay. He finds himself on the opposite corner of where he started and wants to return to his truck as soon as possible. The field is 450 yd by 600 yd. How far will he walk if he walks diagonally across the field, and how much distance will he save instead of walking around the field? Explain your answer. Make sure to use the Pythagorean Theorem when solving this word problem.
Answer:
750 yards
Step-by-step explanation:
I entered the area of the field into a Pythagorean Theorem Calculator and it concluded that the diagonal length of the field would be approximately 750 yard.
Answer:
300 yd saved
Step-by-step explanation:
The length of the diagonal of the field is found using the Pythagorean Theorem and is
d = √( 450 yd)² + ( 600 yd)² ) = √562500 yd² = 750 yd is the diagonal distance. If, on the other hand, the farmer walks the length and width of the perimeter of the field, that would be 450 yd + 600 yd, or 1050 yd.
The farmer could spare himself 1050 - 750, or 300 yd, of walking if he crosses the field along a diagonal.
Bill is doing a fundraiser for soccer. He needs at least $100 worth. Candy bars cost two dollars each insurance cost $10 each Hemist sell more than four candy bars
Bill needs to sell more than 45 candy bars to reach his fundraising goal of $100, after factoring in his insurance cost.
Explanation:Bill is trying to raise a minimum of $100 for soccer. If each candy bar is priced at $2 and he has an insurance cost of $10, we can start calculating how much product he needs to sell to reach his goal.
Firstly, we subtract the insurance cost from the total he needs to raise. This is because the insurance cost is a fixed cost that he needs to cover regardless of the number of candy bars sold. Hence, $100 - $10 = $90.
Now, the remaining $90 needs to be covered by selling candy bars. As each candy bar costs $2, we divide $90 by $2 to find out how many candy bars he needs to sell. Therefore, $90 ÷ $2 = 45 candy bars.
This shows that Bill needs to sell more than 45 candy bars to reach his goal, taking into account his initial fixed insurance cost.

As x gets larger, y gets smaller. Only one of the graphs has that characteristic.
Line of the graph (3) could be the graph of the points in the table.
To determine which line could be the graph of the points in the table, we can plot the points and then draw a line that passes through all three points.
The line that passes through all three points is the line that intersects the y-axis at 0 and has a slope of −2.
Therefore, the line that could be the graph of the points in the table is:

Find the unknown angle measure by solving for the given variable
Answer choices are: 125, 35, 40, and 140.
A straight line is 180°. So you can do:
(15x - 4) + (5x - 8) = 180 Simplify
20x - 12 = 180
20x = 192 Find the value of x
x = 9.6
m∠ABD = 15x - 4 Plug in x = 9.6
m∠ABD = 15(9.6) - 4 = 144 - 4 = 140°
m∠DBC = 5x - 8 Plug in 9.6
m∠DBC = 5(9.6) - 8 = 48 - 8 = 40°
Final answer:
To find the unknown angle, use the trig identity sin(90° - x) = cos x, ensure the calculator is in radian mode, and check if the answer is reasonable.
Explanation:
To find the unknown angle measure in the given problem, we need to use the trigonometric identity sin(90° - x) = cos x. This identity is useful when dealing with right-angled triangles and can help in finding missing angles when other angles or sides are known.
First, we need to identify the known values within the problem and the given equation. Assuming we are looking for value 'a', we then solve the equation by substituting the appropriate known values into it. After that, we need to ensure that our calculator is set to radian mode, as the instructions suggest that angle measurements should be in radians.
After obtaining the numerical solution, it is important to check if the answer is reasonable and makes sense within the context of the problem.
Which of the following equations describes the graph?
Answer:
y = 1/2x^2 - 2x + 1
Step-by-step explanation:
The equation of the parabola in vertex form is y = 1/2 (x - 2)^2 - 1. By finding the vertex at (2,-1) we plug in the point into the formula y = a(x-h)^2 + k. To convert it to standard form like the equations listed, multiply through the distributive property to clear the parenthesis.
y = 1/2 (x-2)(x-2) - 1
y = 1/2 (x^2 - 4x + 4) - 1
y = 1/2x^2 - 2x + 2 - 1
y = 1/2x^2 - 2x + 1
