Answer: Q=24
Step-by-step explanation: 6•4=24
Hey there!
Question/Equation: Q/6 = 4
Steps to solve this equation ⬇️
q/6 = 4
We can substitute “q” as an invisible 1 (for now)
• MULTIPLY by 6 on each of your side
q/6 = 4
q / 6 * 6 = 4 * 6
• CANCEL OUT: 1/6 * 6 because that gives you 1
• KEEP: 4 * 6 because it helps us solve for the actual value of q
• New question/equation: q = 4 * 6
4 * 6 = 24 ; 24 = 4 * 6
Thus, we have answered your question: q = 24
Good luck on your assignment and enjoy your day!

Group A
Restricted the powers of the king
Guaranteed certain rights and liberties to the people
Established England as a constitutional monarchy
Group B
Nobles and church leaders had certain rights that
the king could not take away
The punishment for a freeman or merchant could
not take away his means of making a living
Women could request arrests only if their husbands
were murdered
Group C
Applied the law equally throughout the land
Used juries to help make decisions
Answer:
Group B.
Step-by-step explanation:
Magna Carta is considered as one of the most document in the history of England. The document was signed by King John on June 15, 1215. The document was a result of barons who stood in oppose to the King and forced him to write this document restricting the right's of the Crown. There are total 63 clauses in the document.
The set of group that describes basic principes of the Magna Carta is Group B. The document bestows churches the rights to chose their leaders without any interference from the King. These rights, according to the document were not to be taken away from the church. This principle can be found in Clause 1 of the document. Another Clause that permits freeman and merchants of continue making their livelihood can be found in Clause 20. Clause 20 permits freeman and merchants to exercise their livelihood even after they were punished. And, Clause 54, of the document gave woman rights to make an appeal to arrest only if their husbands were murdered.
Therefore Group B is the correct answer.

Write an equation to solve the problem.
Answer:
5s + 12b <2700b
Step-by-step explanation:
What is the equation of a parabola that passes through the points (−5, −10), (−3, 2), and (2, −3)?
A. y = −x2 − 2x + 5
B. y = −x2 + 6x − 7
C. y = −189x2 − 289x + 353
D. y = −x2 − 3x + 2
Answer:
A
Step-by-step explanation:
Using the standard form of the parabola , y = ax² + bx + c ( a ≠ 0 )
Substitute the given points into the equation and solve for a, b, c using simultaneous equations.
(- 5, 10 )
- 10 = a(- 5)² - 5b + c, that is
25a - 5b + c = - 10 → (1)
(- 3, 2 )
2 = a(- 3)² - 3b + c, that is
9a - 3b + c = 2 → (2)
(2, - 3 )
- 3 = a(2)² + 2b + c , that is
4a + 2b + c = - 3 → (3)
Eliminate c from the equations
Subtract (2) from (1) term by term
16a - 2b = - 12 → (4)
Subtract (3) from (2) term by term
5a - 5b = 5 → (5)
Multiply (4) by 5 and (5) by - 2 then add to eliminate b
80a - 10b = - 60 → (6)
- 10a + 10b = - 10 → (7)
Add (6) and (7) term by term
70a = - 70 ( divide both sides by 70 )
a = - 1
Substitute a = - 1 into (4) and evaluate for b
- 16 - 2b = - 12 ( add 16 to both sides )
- 2b = 4 ( divide both sides by - 2 )
b = - 2
Substitute a = - 1, b = - 2 into (3) and evaluate for c
- 4 - 4 + c = - 3
- 8 + c = - 3 ( add 8 to both sides )
c = 5
Thus a = - 1, b = - 2 and c = 5
Substitute these values into the standard parabola, that is
y = - x² - 2x + 5 → A
Here we want to find the equation of the parabola that passes through the points (-5, -10), (-3, 2), and (2, -3).
We will get, by brute force, that the correct option is A:
y = -x^2 - 2x + 5
To find the correct option we can use brute force.
We do know the options, so what we can do is just evaluate the given options in the x-values of the points, and see if we get the same y-value that the point.
We can start with option A:
A: y = -x^2 - 2x + 5
For the first point (-5, -10) we have x = -5, evaluating in this we get:
y = -(-5)^2 - 2*(-5) + 5 = -25 + 10 + 5 = -10
Now let's try with the next point (-3, 2), we have x = -3
y = -(-3)^2 - 2*(-3) + 5 = -9 + 6 + 5 = 2
Now we can try with the last point (2, -3), where x= 2
y = -(2)^2 - 2*2 + 5 = -4 - 4 + 5 = -3
So we got all the correct y-values (the second value for each point) thus we can conclude that this one is the correct option.
The correct option is A: y = -x^2 - 2x + 5

a furlong is a distance of 180 yards. a fortnight is a time period of two weeks. a race horse is running at a speed of 7 yards per second. what is his speed in furlongs per fortnight?
The race horse's speed is approximately 256 furlongs per fortnight.
To determine the race horse's speed in furlongs per fortnight, we need to convert both the distance and time units to their respective values.
1 furlong is equal to 180 yards, so the horse's speed in yards per second (7 yards/second) can be converted to furlongs per second:
Speed in furlongs per second = (7 yards/second) / (180 yards/furlong) = 7/180 furlongs/second
Next, we need to convert the time from seconds to fortnights. Since a fortnight is a time period of two weeks, and there are 7 days in a week, a fortnight consists of 14 days:
Time in seconds per fortnight = (14 days/fortnight) * (24 hours/day) * (60 minutes/hour) * (60 seconds/minute) = 1,209,600 seconds/fortnight
Finally, we can calculate the horse's speed in furlongs per fortnight by multiplying the speed in furlongs per second by the time in seconds per fortnight:
Speed in furlongs per fortnight = (7/180 furlongs/second) * (1,209,600 seconds/fortnight) = 46,080/180 furlongs/fortnight ≈ 256 furlongs/fortnight
The race horse's speed is approximately 256 furlongs per fortnight.

ten 4th grade girls and ten 7th grade girls were randomly selected. their heights, in inches, are recorded below. q9 on average, 7th grade girls tend to be about question blank 1 of 2 choose your answer... inches taller than 4th grade girls. which statement is true? question blank 2 of 2 choose your answer...
On average, 7th grade girls tend to be about 5 inches taller than 4th grade girls. The correct choice is the statement "On average, 7th grade girls tend to be about 5 inches taller than 4th grade girls" is true.
Explanation: Given the data for ten 4th grade girls and ten 7th grade girls with their heights recorded in inches, we need to determine whether the given statement is true or false. Here are the heights of 4th grade girls:57, 60, 53, 59, 54, 55, 59, 57, 56, 55.Here are the heights of 7th grade girls:63, 64, 65, 64, 69, 61, 65, 63, 67, 67.The average height of 4th grade girls is calculated as follows:
Total height of 4th grade girls = 57 + 60 + 53 + 59 + 54 + 55 + 59 + 57 + 56 + 55 = 565.
Average height of 4th grade girls = Total height of 4th grade girls / Number of 4th grade girls= 565 / 10 = 56.5.
So, the average height of 4th grade girls is 56.5 inches.
The average height of 7th grade girls is calculated as follows:
Total height of 7th grade girls = 63 + 64 + 65 + 64 + 69 + 61 + 65 + 63 + 67 + 67 = 658.
Average height of 7th grade girls = Total height of 7th grade girls / Number of 7th grade girls= 658 / 10 = 65.8.
So, the average height of 7th grade girls is 65.8 inches. On average, 7th grade girls tend to be about (65.8 - 56.5) = 9.3 inches taller than 4th grade girls.

B.
9 + 9 = 11 + 7
c.
19 = 13 + 5
D.
20 - 12 = 4 + 4
The statement which is not true is c. 19 = 13 + 5
What is an expression?An expression is a number, or a variable, or a combination of numbers and variables and operation symbols.
The given statements are,
A. 7 + 7 = 19 - 5
B. 9 + 9 = 11 + 7
C. 19 = 13 + 5
D. 20 - 12 = 4 + 4
Taking each statement one by one,
A. 7 + 7 = 19 - 5
So, L.H.S. = 7 + 7 = 14
and R.H.S. = 19 -5 = 14
Thus, L.H.S = R.H.S
Therefore the statement is true.
B. 9 + 9 = 11 + 7
So, L.H.S. = 9 + 9 = 18
and R.H.S. = 11 + 7 = 18
Thus, L.H.S = R.H.S
Therefore the statement is true.
C. 19 = 13 + 5
So. So, L.H.S. = 19
and R.H.S. = 13 + 5 = 18
Thus, L.H.S ≠ R.H.S
Therefore the statement is not true.
D. 20 - 12 = 4 + 4
So, L.H.S. = 20 - 12 = 8
and R.H.S. = 4 + 4 = 8
Thus, L.H.S = R.H.S
Therefore the statement is true.
Thus, the statement which is not true is c. 19 = 13 + 5.

8 miles per hour.
Today the boys went for a 20 miles trip, each boy was biking at his usual speed. How long did John wait for Brian at the finish line?
PLZZZZZZZZ HELP QIUCK
Answer:
John waited for Brain at the finish line for a half-hour. (or 30 minutes)
Step-by-step explanation:
The rule of the distance is D = s × t, where
s is the speed to travel the distance Dt is the time taken to cover the distance DLet us use this rule to solve the question
∵ John's speed = 10 miles/hour
∵ Brian's speed = 8 miles/hour
→ Slower speed takes more time
∵ The distance of the trip is 20 miles
∴ D = 20 miles
→ Find the time of each one, using the rule above
∵ D = s × t
→ Find John's time
∴ 20 = 10 × t
∴ 20 = 10t
→ Divide both sides by 10
∴ 2 = t
∴ John's time = 2 hours
→ Find Brian's time
∴ 20 = 8 × t
∴ 20 = 8t
→ Divide both sides by 8
∴ 2.5 = t
∴ Brain's time = 2.5 hours
→ Subtract their times to find for how long John waited
∵ 2.5 h - 2 h = 0.5 h
∴ The difference between their times is 0.5 hour
∴ John waited for Brain at the finish line for a half-hour (or 30 minutes)

A piece of equipment has two components, A and B. The equipment will fail if either component A or B fails. If the system Has a probability of failure =.003, and A has a reliability of 998 , what is the reliability of B ?
The reliability of component B in the equipment system can be calculated based on the given information that the probability of system failure is 0.003 and component A has a reliability of 0.998.
The reliability of a system is the probability that it will function without failure over a specified period. In this case, the system will fail if either component A or B fails. Let's denote the reliability of component B as R(B). The probability of system failure is equal to the complement of the reliability, so we have:
Probability of failure = 1 - R(B) = 0.003.Given that the reliability of component A is 0.998, we know that the system will only fail if both components A and B fail simultaneously. Since the system failure probability is very low (0.003), we can assume that the probability of both components failing together is negligible.
Probability of failure = Probability of failure of A * Probability of failure of B. Since the probability of failure of A is negligible compared to the system failure probability, we can simplify the equation as: 1 - R(B) ≈ 0.003. Solving for R(B), we find: R(B) ≈ 1 - 0.003 = 0.997
