The price of an item has been reduced by 60% the original price was $20 what is the price of the item now

Answers

Answer:

6

Step-by-step explanation:

20 times 0.3 is 6

Answer:

reduced by 20% so that means it is going to be 20% cheaper. You need to take off 20% of $60

20% is 0.2

of in math ALWAYS means multiply

0.2 X 60 = 12

You get 12 off  

60 - 12 = 48

the new price is $48.00

Here is another way. You get 20 % off and that leaves 80% that you have to pay.

80% of 60  

= 0.8 x 60

= 48

You pay $48.00

I have two questions. Both need written in standard form. Please show your work!!
1.) What is : y= 1/5x + 1/3 in standard form?
2.) What is : y= 2/7x - 1/3 in standard form?

Answers

Answer:

1) 3x - 15y = 5

2) 6x - 21y = 7

Step-by-step explanation:

standard form:  Ax + By = C

1) y = 1/5x + 1/3

multiply each side by 15 to eliminate fractions: 15y = 3x + 5

final form: 3x - 15y = -5

2) y = 2/7x - 1/3

multiply each side by 21 to eliminate fractions: 21y = 6x - 7

final form: 6x - 21y = 7

Hope this helps

Answer:

3.1 * 10^10

Step-by-step explanation:

we know 1 billion is 1,000,000,000

In scientific notation

1,000,000,000=1 * 10^9

To find the value of 31 Billion

Multiply the value of one billion for 31

so

31 * 1 * 10^9  = 31 * 10^9

= 3.1 *  10^10

Is the following relation a function?
Y = 3x

Answers

Answer:

Yes

Step-by-step explanation:

If you subsitute for x, x will only repeat if it has the same y value.

Yes, The given relation is a function.

Here,

The relation is given as; Y = 3x

We have to find the given relation is a function or not.

What is Function?

A relation is said to be function if there is exactly one value for each value of y.

Now,

The given relation is,

Y = 3x

When, we put x = 1 then y = 3

And, when x = 2 then y = 6 and so on.

Clearly, there is exactly one value of x for value of y.

So, The given relation is a function.

A triangle is a three sided polygon, which has three vertices and three angles which has the sum 180 degrees.

We have to given that;

Base of height = 500

Angle = 10°

Now, We can formulate;

⇒ tan 10° = x / 500

⇒ 0.17 = x / 500

⇒ x = 85

Thus, The value of x round to the nearest tenth is,

⇒ x = 85

What are the lengths of side AB and side BC?

Answers

Answer: AB=20, BC=14

Step-by-step explanation:

set AB together with the side congruent to it (which is DC)

3x-7=x+11

subtract x and add 7 to both sides

2x=18

divide both sides by 2

x=9

plug 9 in for AB.

3(9)-7

27-7=20.

now do the same for BC

Answer:

AB = 20

BC = 14

Step-by-step explanation:

ABCD is a parallelogram

Opposite sides of a parallelogram are equal.

Therefore,

AB = DC

3x - 7 = x + 11

3x - x = 11 + 7

2x = 18

x = 18/2

x = 9

AB = 3x - 7 =3*9 - 7 = 27 - 7 = 20

7y - 7 = 3y + 5

7y - 3y = 7 + 5

4y = 12

y = 12/4

y = 3

BC = 7y - 7 = 7*3 - 7= 21 - 7 = 14

Gonzalo is trying to find the unit price On a 6-pack of orange juice on sale for $6.99. His sister says that at that price, each bottle of orange juice would cost over $1.05. Is she correct?

Answers

Answer:

Yes

Step-by-step explanation:

Unit prices come from dividing the price, $6.99, by the amount of product, 6,

6.99 ÷ 6 = 1.165

Now, because you cannot have more than two digits in the cents part, you would round that up to $1.17 which is over $1.05 dollars per bottle.

y = -3(-3) = 9

y = -3(-2) = 6

y = -3(-1) = 3

There is no solution for either variable without further information, as there are two variables given, but only one relationship between them.

You could however use them as a description of a line, which gives every possible solution.

35x - 7y = 49

7y = 35x - 49

y = 5x - 7

Step-by-step explanation:

The sides of a 30-60-90 triangle are always in the ratio 1:√3:2.

Which forces do scientists believe are responsible for the movement of Earth'stectonic plates? please help me!!!!! im confused Write a 5 sentence summary about the story. Why do governments exist? One major reason is that they create rules. But what rules are necessary or desirable? That is open to question, and different types of governments have certainly created a wide variety of rules.GOVERNMENTs almost certainly originated with the need to protect people from conflicts and to provide law and order. Why have conflicts among people happened throughout history? Many people, both famous and ordinary, have tried to answer that question. Perhaps human nature dictates selfishness, and people inevitably will come to blows over who gets what property or privilege. Or maybe, as KARL MARX explains, it is because the very idea of "PROPERTY" makes people selfish and greedy.Whatever the reasons, governments first evolved as people discovered that protection was easier if they stayed together in groups and if they all agreed that one (or some) in the group should have more power than others. This recognition is the basis of SOVEREIGNTY, or the right of a group (later a country) to be free of outside interference.A country, then, needs to not only protect its citizens from one another, but it needs to organize to prevent outside attack. Sometimes they have built Great Walls and guarded them carefully from invaders. Other times they have led their followers to safe areas protected by high mountains, wide rivers, or vast deserts. Historically, they have raised armies, and the most successful ones have trained and armed special groups to defend the rest. Indeed in the twentieth century, governments have formed alliances and fought great world wars in the name of protection and order.In more recent years, government responsibilities have extended to the economy and public service. An early principle of capitalism dictates that markets should be free from government control. But when economies spun out of control during the 1930s, and countries sank into great depressions, governments acted. The United States Congress created the FEDERAL RESERVE SYSTEM in the early twentieth century to ward off inflation and monitor the value of the dollar. FRANKLIN ROOSEVELT and his "BRAIN TRUST" devised New Deal programs to shock the country into prosperity.Perhaps government responsibility to provide social programs to its citizens is the most controversial of all. In the United States the tradition began with the New Deal programs, many of which provided people with relief through jobs, payments, and food. During the 1960s PRESIDENT LYNDON JOHNSON unveiled his "GREAT SOCIETY" programs aimed at eliminating poverty in the entire country. Many European countries today provide national medical insurance and extensive welfare benefits. Many Americans criticize these programs as expensive ventures that destroy the individual's sense of responsibility for his/her own well being. So the debate over the proper role of government in providing for its people's general welfare is still alive and well today.Though the rules and responsibilities vary greatly through time and place, governments must create them. Governments provide the parameters for everyday behavior for citizens, protect them from outside interference, and often provide for their well-being and happiness.
