In 45 years will be 4 times older how old is she now

Answers

Answer 1

Answer and Step-by-step explanation:

The key for this has a current age and a future age. Sometimes these problems have more than one person or has a past age.

 

       current age     future age

        x                    x+45

 

The future age is 4 times current age

 

x+45 = 4x

   45 = 3x

   15 = x

 

She is currently 15. 45 years from now she will be 60.

60 is 4 times her current age. So right now, she is 15.

David wants to donate $400 to a charity. He has already saved $125. He earns $9 each day at his after-school job. What is the least number of days that David must work to earn $400?

Answers

Answer:

About 31 days

Step-by-step explanation:

Since he already has $125, you can subtract that amount from how much he needs to earn. $400 - $125 = $275 that he must earn.

Divide the remaining amount by how much he earns a day to find the number of days he must work to reach his goal.

$275 ÷ $9 ≈ 30.5 (I got 30.5 repeating). I rounded up to 31 days.

Jinan has $25 dollars to spend on drinks for
the class party. A case of drinks cost $2.50.
Create an inequality to represent the
relationship between the amount of money
Jinan has and how many cases of drinks she
can buy.

Answers

Answer:

$2.50X > $25

Step-by-step explanation:

the cost times the unknown will be less or equal to$25

The inequality function to  represent the relationship between the amount of money should be considered as the $2.50X > $25.

Calculation of the inequality function:

Since

Jinan has $25 dollars to spend on drinks for the class party.

And, A case of drinks cost $2.50.

So here the inequality function should be $2.50X > $25

Here the cost should be less or equivalent to 25.

Students in the fifth-grade class bought 28 yards of fabric to make pennants for a pep rally.
Each pennant requires 13 yard of fabric.
If the students have already made 35 pennants from the fabric, how many more pennants can they still make?
A. 63 pennants
B. 49 pennants
C. 21 pennants
D. 7 pennants

Answers

Answer:

C. 21 pennants

Step-by-step explanation:

35-28=7

7 divided by 1/3= 21/1 or 21

The number of pennants that can be made is given by equation A = 49 pennants

What do you mean by an Equation?

Equations are statements in mathematics that have two algebraic expressions on either side of the equals (=) sign.

It displays the similarity of the connections between the phrases on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are examples of the parts of an equation. When creating an equation, the "=" symbol and terms on both sides are necessary.

Given data ,

Let the number of pennants required be represented as A

The amount of fabric bought by students = 28 yards

The amount of fabric required by each pennant = 1/3 yards

The total number of pennants made by students = 35 pennants

So , the number of pennants that can be made is N

N ( 1 / 3 ) = 28 be equation (1)

Multiply by 3 on both sides , we get

N = 84 pennants

So , the remaining number of pennants A = N - number of pennants made by students

On simplifying the equation , we get

The remaining number of pennants A = 84 - 45

The remaining number of pennants A = 49 pennants

Hence , the number of pennants is 49

Excerpt from FederalistRead the passage.excerpt from Federalist No. 78 by Alexander HamiltonIn 1787 and 1788, Alexander Hamilton, John Jay, and James Madison wrote the Federalist Papers to persuade voters to ratify the proposed Constitution of the United States of America. These papers included essays about all three branches of government: executive, legislative, and judicial. In Federalist No. 78, Hamilton focused specifically on the judicial branch.Whoever attentively considers the different departments of power must perceive, that, in a government in which they are separated from each other, the judiciary, from the nature of its functions, will always be the least dangerous to the political rights of the Constitution; because it will be least in a capacity to annoy or injure them. The Executive not only dispenses the honors, but holds the sword of the community. The legislature not only commands the purse, but prescribes the rules by which the duties and rights of every citizen are to be regulated. The judiciary, on the contrary, has no influence over either the sword or the purse; no direction either of the strength or of the wealth of the society; and can take no active resolution whatever. It may truly be said to have neither FORCE nor WILL, but merely judgment; and must ultimately depend upon the aid of the executive arm even for the efficacy of its judgments.This simple view of the matter suggests several important consequences. It proves incontestably, that the judiciary is beyond comparison the weakest of the three departments of power; that it can never attack with success either of the other two; and that all possible care is requisite to enable it to defend itself against their attacks. It equally proves, that though individual oppression may now and then proceed from the courts of justice, the general liberty of the people can never be endangered from that quarter; I mean so long as the judiciary remains truly distinct from both the legislature and the Executive. For I agree, that "there is no liberty, if the power of judging be not separated from the legislative and executive powers.'' And it proves, in the last place, that as liberty can have nothing to fear from the judiciary alone, but would have every thing to fear from its union with either of the other departments; that as all the effects of such a union must ensue from a dependence of the former on the latter, notwithstanding a nominal and apparent separation; that as, from the natural feebleness of the judiciary, it is in continual jeopardy of being overpowered, awed, or influenced by its co-ordinate branches; and that as nothing can contribute so much to its firmness and independence as permanency in office, this quality may therefore be justly regarded as an indispensable ingredient in its constitution, and, in a great measure, as the citadel of the public justice and the public security.The complete independence of the courts of justice is peculiarly essential in a limited Constitution. By a limited Constitution, I understand one which contains certain specified exceptions to the legislative authority; such, for instance, as that it shall pass no bills of attainder, no ex-post-facto laws, and the like. Limitations of this kind can be preserved in practice no other way than through the medium of courts of justice, whose duty it must be to declare all acts contrary to the manifest tenor of the Constitution void. Without this, all the reservations of particular rights or privileges would amount to nothing.Question 4 (3.75 points) How does Hamilton's use of the phrase "beyond comparison" and the word never in this excerpt from Paragraph 2 affect the passage?It proves incontestably, that the judiciary is beyond comparison the weakest of the three departments of power; that it can never attack with success either of the other two; . . . that . . . the general liberty of the people can never be endangered from that quarter; I mean so long as the judiciary remains truly distinct from both the legislative and the Executive.Question 4 options:They help convey the intensity of Hamilton's belief in his position.They help convey the honesty with which Hamilton approaches the subject.They help provide specifics about Hamilton's position.They help provide a diverse sample of opinions on the subject.
