Answer:

expression for total cost is given by

[tex]0.80(3.95x+4.25y+5.99z)[/tex]

Step-by-step explanation:

Here we need to find the expression for the total cost

Let us find the cost for x pounds of peanut , y pounds of cashews and z pounds of almonds

cost of 1 pound of peanut = $3.95

cost of x pounds of peanut = $3.95x

cost of 1 pound of cashews = $4.25

cost of y pounds of cashews = $4.25y

cost of 1 pounds of almonds = $5.99

cost of z pounds of almonds = $5.99z

total cost = [tex]3.95x+4.25y+5.99z[/tex]

cost after 20% off = total cost - 20% of total cost

                                         = 80% of total cost  

cost after 20% off =80%[tex](3.95x+4.25y+5.99z)[/tex]

cost after 20% off =[tex]0.80(3.95x+4.25y+5.99z)[/tex]

now we can plug x= 2 , y= 3 and z=1

so we have

cost after 20% off =[tex]0.80(3.95(2)+4.25(3)+5.99(1))[/tex]  =$ 21.31          

The expression is ((2 x $3.95) + (3 x $4.25) + (1 x $5.99)) x (1 - 0.20) which equals to $21.31.

To find the total cost of 2 pounds of peanuts, 3 pounds of cashews, and 1 pound of almonds with a 20% discount, we need to first calculate the original total cost of the nuts without the discount.

We do this by multiplying each type of nut's price per pound by the number of pounds purchased and summing these amounts up.

The cost for the peanuts is 2 pounds x $3.95 per pound = $7.90.

For the cashews, it is 3 pounds x $4.25 per pound = $12.75.

For the almonds, it is 1 pound x $5.99 per pound = $5.99.

The sum of these costs will give us the total original cost.

The total original cost is therefore $7.90 (peanuts) + $12.75 (cashews) + $5.99 (almonds) = $26.64.

Next, we apply the 20% discount by multiplying the total original cost by 20% (or 0.20) to find the discount amount, and then subtract this discount amount from the total original cost to find the discounted total cost:

Discount amount = $26.64  imes 0.20 = $5.33. Discounted total cost = $26.64 - $5.33 = $21.31.

Therefore, the expression that can be used to find the total cost is: ((2 x $3.95) + (3 x $4.25) + (1 x $5.99)) x (1 - 0.20)

Answer:

Step-by-step explanation:

Lets try to simplify each to check which one is incorrect so it will be NOT true

first one is :

distribute the exponent so :

[tex](3x^2y^5)^3 =3^3x^{2*3}y^{5*3}[/tex]

[tex]27x^6y^{15}[/tex] CORRECT

Second one is :

[tex](1000x^{12}y^{20}z^{-30})^{0} =1[/tex]

CORRECT because anything raised to exponent 0 is 1 .

Last one is :

[tex]4^2 *4^3 = 4^{2+3}\\=4^{6}\\=(4)^{2*3}\\=16^{3}[/tex]

so Last is INCORRECT

Answer:

B) 21

Step-by-step explanation:

There are 7 cars total and 5 slots to fill for the showroom selections. Put another way, there are 7-5 = 2 cars that don't make it to the showroom floor. Since this value (2) is smaller than the previous number of slots (5), it makes it easier to ask the question "how many ways are there to pick 2 cars that don't make it to the show room floor?" instead of "how many ways are there to pick 5 cars that make it to the showroom floor?". We'll get the same answer either way.

So we have 7 total to pick from for slot 1, and then 6 left over for slot 2. Making 7*6 = 42 permutations. Order does not matter, meaning that picking a red car and then a blue car is the same as picking a blue and then red. The count 42 has double counted, so we divide by 2 to sort this out

42/2 = 21 represents the number of combinations. We can see this if we use the nCr combination formula with n = 7 and r = 2

nCr = (n!)/(r!*(n-r)!)

7C2 = (7!)/(2!*(7-2)!)

7C2 = (7!)/(2!*5!)

7C2 = (7*6*5!)/(2*5!)

7C2 = (7*6)/2

7C2 = 42/2

7C2 = 21

a similar computation happens if you use n = 7 and r = 5.

An equation to represent this would be 12x+2=T.

x=10 people per large table.

If T=122 then we just have to isolate x on one side of the equation. The first step is to replace T with 120 and then subtract 2 on both sides (to cancel the +2) to get 12x=120. Cancel the 12 by dividing both sides by 12 to get x=10. The number of people seated at each large table would be 10. Hopefully I explained this correctly and helped you understand.

Final answer:

To determine the number of guests seated at each large table, we use the equation T = 12x + 2, where T is the total number of guests and x is the number of guests at each large table. Solving for x given T = 122 guests, we find that

x = 10, meaning there are 10 guests at each large table.

Explanation:

The student asks for help with writing an equation to represent the total number of guests T and the number of people x at each large table, given that there are 12 large tables and one small table with 2 guests. The student also seeks to find out how many people are seated at each large table if there is a total of 122 guests.

The equation to represent the scenario is T = 12x + 2, where T is the total number of guests, and x is the number of guests at each large table. Since we know there are 122 guests in total:

Substitute T with 122 in the equation: 122 = 12x + 2.

Subtract 2 from both sides to isolate the terms with x: 120 = 12x.

Divide both sides by 12 to solve for x: x = 120 / 12.

Calculate the result: x = 10.

Therefore, there are 10 guests seated at each large table.

Arpita's present age is found using the information about Shilpa's age three years ago and the fact that Arpita's age is three times Shilpa's age.

To find Arpita's present age, we need to solve the equation involving their ages. Let's assume Shilpa's age three years ago was x. According to the problem, Arpita's age is three times Shilpa's age, so Arpita's age three years ago was 3x. Now, let's find Arpita's present age.

Therefore, Arpita's present age is 3x + 3.

1.The correct answers here are the options A and C.

Under the United States Constitution, the powers that the states possess are those that are not given to federal government and those that are not prohibited by the Constitution itself. This is clearly seen here in the 10th Amendment. The states are free to set forth any laws that are constitutional so this does not mean any powers people want. 

2.The correct answer here is the option A.

John C. Calhoun believed as did some other prominent politicians that nullification of federal laws was justified as the Constitution does not expressly give Congress the right to control states. But nullification is actually not legal and not true because of the Supremacy Clause that states that the Constitution and the federal laws created in accordance with it are the supreme law of the land. Also,  Article III of the Constitution states that it is the federal judiciary that has the final say in the constitutionality of a law.

3.The correct answer here is the option A.

When the citizens of the United States think about  the Constitution they mainly think about the Constitution of the United States. But before the colonies came together to create the Union they already created their own individual constitutions and entered the Union as free states. But these have been changed after the establishment of the Union in order to more reflect the Constitution of the United States. 

The Fifth Amendment prohibits federal and state governments from carrying out certain actions:

Double Jeopardy: It protects individuals from being tried twice for the same offense after being acquitted or convicted once.

Self-Incrimination: It grants individuals the right not to be compelled to be a witness against themselves in a criminal case.

Due Process: It ensures that no person shall be deprived of life, liberty, or property without due process of law.

Eminent Domain: It establishes that private property cannot be taken for public use without just compensation.

Answer:

the first one is -1 15/18 the next one is -1 14/18

Step-by-step explanation:

The mixed numbers that are equivalent to −1 5/6 ​ and​ −1 7/9 are −1 15/18 and −1 14/18, respectively.

The least common multiple that is divisible by both a and b is the smallest positive integer, lowest common multiple, or smallest common multiple of two numbers a and b, generally indicated by LCM.

The LCD is the lowest common denominator for any two or more fractions. Now, for the given mixed numbers the two fractions given are 5/6 and 7/9, therefore, their LCD is the LCM of the denominator, in this case, the denominators are 6 and 9, therefore, the LCM of these two is 18.

Further to get the mixed number, the fraction is needed to be multiplied such that their denominator becomes 18.

Multiply both the numerator and the denominator by 3, therefore,

(5/6) × (3/3) = 15/18

Multiply both the numerator and the denominator by 2, therefore,

(5/6) × (2/2) = 14/18

Thus, the mixed fractions can be written as,

hence, the mixed numbers that are equivalent to −1 5/6 ​ and​ −1 7/9 are −1 15/18 and −1 14/18, respectively.

The expression (1/7x + 11/7) can be factored as (x + 11) after dividing each term by 1/7. The factored form simplifies the original expression and represents the common factor, 1/7, that was pulled out.

To factor out 1/7 from the expression (1/7x + 11/7), you can simply divide each term in the expression by 1/7. This is equivalent to multiplying each term by the reciprocal of 1/7, which is 7/1.

Starting with the expression (1/7x + 11/7):

(1/7x) ÷ (1/7) = x

(11/7) ÷ (1/7) = 11

So, factoring out 1/7, the expression becomes x + 11.

Therefore, the factored form of (1/7x + 11/7) is (x + 11).
