Similarities between justice and revenge

Answers

Justice and revenge are both punishments and Justice is a form of revenge.

Final answer:

Justice and revenge differ in intentions and outcomes. Justice focuses on fairness and societal laws, while revenge is driven by personal vendettas. It's crucial to differentiate between the two concepts to avoid perpetuating harm.

Explanation:

Justice and revenge both involve the desire for consequences towards a wrongdoing, but they differ in their intentions and outcomes. While justice aims for fairness and upholding societal laws, revenge seeks to harm those who have caused harm, often driven by personal emotions.

One key difference between justice and revenge is that justice is typically carried out within a legal framework and aims to restore balance in society, whereas revenge is driven by personal vendetta and can perpetuate cycles of violence.

It's essential to differentiate between the two concepts, as justice aligns with societal norms and legal systems, while revenge risks leading to further harm and conflict.

h(t)=50− 5 t ​
h(35)=?

Answers

Answer:

Step-by-step explanation:

H(t) = 50 - t/5

h(35)=50-35/5

=50-7

=43

h(35) = 43

The quantity represented by h(t) is -125 at time t=35.

The function h(t) represents a certain quantity (for example, height, distance, etc.) as a function of time ‘t’. Here, you want to find the value of h(t) at t=35.

We can substitute t=35 into the function h(t):

h(35) = 50 - 5*35

Now, calculate the expression on the right side to find the value of h(35). This will give you the desired quantity at time t=35. Remember to follow the order of operations (multiplication before subtraction). Let’s calculate it:

h(35) = 50 - 5*35 = 50 - 175 = -125

So, h(35) = -125. This means that the quantity represented by h(t) is -125 at time t=35.

A step on a stairway is at least 8 inches high. What inequality should I write and solve to represent the minimum number of steps between floors that are 10 feet apart?

Answers

To answer this question you would consider that 10 feet equals 120 inches. If you show the 120 inches being broken into groups the size of 8 inches, this would be 15 total steps needed at the most. If the steps were any longer, the number of steps would decrease. I would represent all the possible solutions by writing an inequality that says 120/8 > x or x < 120/8 where x is the number of steps.

Rachel has 60 scones. She sells them to Robbie, Cameron, Louis, Tom and Charlie in that order. Each customer buys more scones then the last and the increase is the same number in each case. Robbie and Cameron's combined total number of scones is three sevenths of the total of Louis, Tom and Charlie. How many scones does each boy buy?

Answers

Robbie bought the smallest amount. Let's use x for that amount.
Let's use n for amount that each following customer increases.

We have:
Robbie=x
Cameron=x+n
Louis=x+n+n
Tom=x+n+n+n
Charlie=x+n+n+n+n

We know that they bought total of 60 scones.
Robbie + Cameron + Louis + Tom + Charlie = 60
x + x+n + x+n+n + x+n+n+n + x+n+n+n+n = 60
5x + 10n = 60 /:5
x + 2n = 12

We are also given this information:
(Robbie + Cameron) = 3/7 * (Louis + Tom + Charlie)
We insert the equations from above:
(x + x+n) = 3/7 * (x+n+n + x+n+n+n + x+n+n+n+n) 
2x + n = 3/7 * (3x + 9n) /*7
14x + 7n = 3* (3x + 9n)
14x +7n = 9x + 27n
We take everything on the left side.
14x + 7n - 9x - 27n = 0
5x - 20n = 0/:5
x - 4n = 0

Now we have two equations:
x + 2n = 12
x - 4n = 0
We solve second one for x and insert it into first one.
x + 2n = 12
x = 4n

4n + 2n =12
6n = 12 /:6
n = 2
x=4*2
x=8


Now we can solve for the amount for each customer.
Robbie=x = 8
Cameron=x+n = 8 + 2 = 10
Louis=x+n+n = 8 + 2 + 2 = 12
Tom=x+n+n+n = 8 + 2 + 2 + 2 = 14
Charlie=x+n+n+n+n = 8 + 2 + 2 + 2 + 2 = 16

Attila the Hun was a ruler of the Hunnic Empire. The Romans feared him greatly until his death since he made quite a habit of invading. The Romans no longer feared him after his death in 453. Let x represent any year. Write an inequality in terms of x and 453 that is true only for values of x that represent years after the year that Attila died.

The inequality would be x > 453 because any year after he died would be more than the year he died.

What is the measure of angle x? m∠x

We know that the total sum of all angles in a triangle has to add up to 180 degrees. Since we know 2 out of the 3 angles, we can subtract the other two angles from 180 to solve for angle x.

x = 180 - 44 - 53 = 83 degrees

Jeremy can row 3/8 of a mile in 1/4 of an hour. What is the unit rate that describes the miles per hour ?

Answers

Since 1/4 * 4 = 1 (the numerator of the unit rate), we need to multiply 3/8 by 4 so the equation stays equal.

3/8 * 4 = 1 1/2

Answer: Jeremy can row 1 1/2 miles per hour. 

Hope this helps!

Answer:

The unit rate that describes miles per hour is 3/2.

Step-by-step explanation:

Jeremy can row 3/8 of a mile in 1/4 of an hour which means he takes 15 minutes.

If Jeremy can row 3/8 of a mile in 1/4 of an hour then he can row 3/8 multiply 4 of a mile in one hour.

Therefore,

Jeremy can row 3/2 of a mile in 1 hour.

Hence,

The unit rate that describes miles per hour is 3/2.

Express Fraz's age in terms of (a) if Fraz is twice the sum of Anne's age and 7

Answers

Jenny is 3 less than half of a, or 1/2a - 3.  Fraz is twice a + 7, or 2a+7.
Final answer:

Jenny's age in terms of Anne's age is j = (1/2)a - 3 and Fraz's age in terms of Anne's age is f = 2(a + 7).

Explanation:

To express Jenny's age in terms of Anne's age (a), we can use the information given that Jenny is 3 years less than 1/2 of Anne's age. Therefore, Jenny's age (j) can be expressed as:

j = (1/2)a - 3

To express Fraz's age in terms of Anne's age (a), we can use the information given that Fraz is twice the sum of Anne's age and 7. Therefore, Fraz's age (f) can be expressed as:

f = 2(a + 7)

PLEASE HELP = simplify 3/4(-10+2/5)

Answers

There are many ways to do this depending on the property you have to use:

If you use the distributive property, you need to distribute 3/4 to -10 and 2/5. Distribute means you will multiply it so your resulting equation will be this:

[tex] \frac{-30}{4} - \frac{6}{20} [/tex]

Before you can add, you need to first make them like terms because you cannot add unlike fractions. Get the LCD and form your new equation:

[tex] \frac{-150+6}{20} [/tex]

Now you can just add them together to get:
[tex] \frac{-144}{20} [/tex]

and then simplify your fraction:
[tex] \frac{-36}{5} [/tex] or - [tex] \frac{36}{5} [/tex] 

The whole fraction becomes negative because when you divide integers and of them is negative, the final answer will be negative.
