What is Unitary Method?

The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.

For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.

12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.

As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.

This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.

Given:

A salad dressing recipe calls for 3⁄4 cup of olive oil for every 1⁄2 cup of vinegar.

So, For 1 cup olive oil the vinegar used

= (1/2) / (3/4)

= 1/2 x 4/3

= 2/3 cup

Now, For 2 cups of Olive oil

= 2/3 x 2

= 4/3 Cups if Vinegar used.

Explain please also the work

Answers

Answer:

y= 1/4x -3

Step-by-step explanation:

point-slope form: y-y1=m(x-x1)

y-2=1/4(x-4)

y-2= 1/4x - 1

y= 1/4x - 3

The equation of a line in point-slope form with slope 1/4 and point (4, 2)

is y - 2 = (1/4)(x - 4).

What are lines and their slopes?

We know lines have various types of equations, the general type is

Ax + By + c = 0, and the equation of a line in slope-intercept form is

y = mx + b.

Where slope = m and b = y-intercept.

The equation of a line is point-slope form is y - y₁ = m(x - x₁).

Given, Slope is 1/4 and has point (x₁, y₁) = (4, 2).

∴ The equation of the given line is y - 2 = (1/4)(x - 4).

Read this article "Do Video Games Make People Violent." After reading the article, do you think video games contribute to violence? Give three evidences to support your opinion. "Do Video Games Make People Violent" hold 1 sec getting link

Answers

Answer:

According to the name of the article and personal experience i would have to say yes they do.

Step-by-step explanation:

1. They contribute to violence because some times they will make you Extremely mad and want to hurt someone or some thing

2. It depends on the type of game some violent game will make you want to copy whats in the game or what happens in the game (Example: Your character beats up or shoots someone you'll sometime pretend to do that IRL)

3. They are addicting and some times even controlling they tempt you to do things including violence.

And those are 3 reasons why violence contribute to playing video games!!

Hope this helped!!! :D

Answer:

After reading the article "Do Video Games Make People Violent" I can conclude that video games can make children more violent. An study released by the Oxford Internet Institute last year suggested frustration at being unable to play a game was more likely to bring out aggressive behaviour than the content of the game itself.   In another study violent video games could be often associated with behaviour problems. In addition one of the students who carried out the Columbine High School massacre in 1999 used a gun he called "Arlene" - allegedly after a character in a novel inspired by the computer game Doom.  In conclusion the research all adds up to one answer, video games resemble a consistent relation between violent video game use and increases in aggressive behaviour, aggressive cognitions and aggressive affect, and decreases in pro-social behaviour, empathy and sensitivity to aggression.
