Cost of a bottle of juice is $ 1.62
Equation for determining the cost of juice is 1.56 + 20x = 33.96
Given,
The cost of a bag of chips = $ 1.56
Number of juice bottles bought by Sarah = 20 pack
Total cost before tax = $ 33.96
Cost of one bottle of juice = x
We have to find x:
Then the equation will be:

(b) Draw the image of ∆PQR after a reflection across the y-axis. Label the image ∆P''Q''R''.
Using translation concepts, the transformed triangles are given in the graph at the end of the answer.
What is a translation?A translation is represented by a change in the function graph, according to operations such as multiplication or sum/subtraction either in it’s range(involving values of y) or in it’s domain(involving values of x). Examples are shift left/right or bottom/up, vertical or horizontal stretching or compression, and reflections over the x-axis or the y-axis, or rotations of a degree measure around the origin.
For this problem, the coordinates of triangle PQR are given as follows:
P(-1,-1), Q(-3,-2), R(-3,-4).
The rule for a 90º clockwise rotation around the origin is given by:
(x,y) -> (y,-x).
Hence the coordinates of triangle P'Q'R' are given by:
P': (-1,-1) -> (-1,1).Q': (-3, -2) -> (-2, 3).R' : (-3, -4) -> (-4, 3).The rule for a reflection over the y-axis is:
(x,y) -> (-x,y).
Hence the coordinates of triangle P''Q''R'' are given by:
P'': (-1,-1) -> (1,-1).Q'': (-3, -2) -> (3, -2).R'' : (-3, -4) -> (3, -4).Both triangles are given in the graph at the end of the answer.

Formulate 600lbs of a 13% cp ration using alfalfa hay (18%cp) and clover 4%cp)
The amount of Alfalfa hay is 385.71 lbs
The amount of Clover is 572.45 lbs.
What is percentage?A percentage is a number or ratio that can be expressed as a fraction of 100.
We have,
Alfalfa hay = 18 % CP
Clover = 4% CP.
The total amount of ration is 600 lbs of a 13% CP.
Let x pounds of alfalfa hay have been used.
The amount of clover will be 600 - x lbs.
The CP amount in 600 lbs mixture will be equal to the sum of CP amounts in x lbs alfalfa and (600 - x) lbs clover.
13% of 600 = 18% of x + 4% of (600 - x)
We need to find x.
13/100 x 600 = 18/100 x (x) + 4/100 x (600 -x)
78 = 18x / 100 + 24 - 4x/100
78 - 24 = 18x/100 - 4x/100

Suppose that a certain college class contains 51 students. Of these, 23 are freshmen, 30 are mathematics majors, and 7 are neither. A student is selected at random from the class.
(a) What is the probability that the student is both a freshman and a mathematics major?
(b) Given that the student selected is a freshman, what is the probability that he is also a mathematics major
Considering the definition of probability and its properties:
the probability that the student is both a freshman and a mathematics major is 3/17. given that the student selected is a freshman, what is the probability that he is also a mathematics major is 3/10.Definition of ProbabitityProbability is the possibility that a phenomenon or an event will happen, given certain circumstances. It is expressed as a percentage.
The probability of any event A is defined as the ratio between the number of favorable cases (number of cases in which event A may or may not occur) and the total number of possible cases. This is called Laplace's Law.
P(A)= number of favorable cases÷ number of total cases
Union of eventsThe union of events, AUB, is the event formed by all the elements of A and B. That is, the event AUB is verified when one of the two, A or B, or both occurs. AUB is read as "A or B".
The probability of the union of two compatible events is calculated as the sum of their probabilities subtracting the probability of their intersection:
P(A∪B)= P(A) + P(B) -P(A∩B)
The intersection of events, A∩B, is the event formed by all the elements that are, at the same time, from A and B. That is, the event A ∩ B is verified when A and B occur simultaneously.
Complementary eventA complementary event, also called an opposite event, is made up of the inverse of the results of another event.
The probability of occurrence of the complementary event A' will be 1 minus the probability of occurrence of A:
P(A´)= 1- P(A)
Conditional probabilityThe conditional probability P(A|B) is the probability that an event A occurs, knowing that another event B also occurs. That is, it is the probability that event A occurs if event B has occurred. It is defined as:
P(A|B) = P(A∩B)÷ P(B)
Probability that the student is both a freshman and a mathematics majorIn first place, let's define the following events:
F: The event that the student is a freshman.M: The event that the student is a mathematics major.You know:
A certain college class contains 51 students. 23 students are freshmen. → P(F)= 23÷51 → P(F)= 23/5130 students are mathematics majors. → P(M)= 30÷51 → P(M)= 30/517 students are neither a freshman or a mathematics mayor → P [(F∪M)']= 7÷51= 7/51The probability that a student is a freshman or a mathematics mayor is:
P [(F∪M)']= 1- P(F∪M)
7/51= 1 - P(F∪M)
7/51 - 1= -P(F∪M)
-44/51= -P(F∪M)
44/51= P(F∪M)
So, the probability that the student is both a freshman and a mathematics major is calculated as:
P(F∪M)= P(F) + P(M) -P(F∩M)
44/51= 23/51 + 30/51 - P(F∩M)
44/51- 23/51 - 30/51= - P(F∩M)
-3/17= - P(F∩M)
3/17= P(F∩M)
Finally, the probability that the student is both a freshman and a mathematics major is 3/17.
Probability that a student is a mathematics major being a freshmanThe probability that a student is a mathematics major, knowing that he is also a freshman, is calculated as:
P(M|F) = P(M∩F)÷ P(M)
So:
P(M|F) = 3/17÷ 30/51
P(M|F) = 3/10
Finally, given that the student selected is a freshman, what is the probability that he is also a mathematics major is 3/10.

[tex]\sf PMT=\dfrac{Pi\left(1+i\right)^n}{\left(1+i\right)^n-1}[/tex]
where:
PMT = monthly payment.P = loan amount.i = interest rate per month (in decimal form).n = term of the loan (in months).Given:
P = $39.950 less any down payment.i = 10.25% / 12 = 0.1025/12n = 7 years = 7 × 12 = 84 monthsPart (a)Down payment = $0
⇒ P = $39,950
[tex]\implies \sf PMT=\dfrac{39950\left(\dfrac{0.1025}{12}\right)\left(1+\left(\dfrac{0.1025}{12}\right)\right)^{84}}{\left(1+\left(\dfrac{0.1025}{12}\right)\right)^{84}-1}[/tex]
[tex]\implies \sf PMT = 668.3892086[/tex]
Therefore, the monthly payment is $668.39.
Part (b)Down payment = $2,000
⇒ P = $39,950 - $2,000 = $37,950
[tex]\implies \sf PMT=\dfrac{37950\left(\dfrac{0.1025}{12}\right)\left(1+\left(\dfrac{0.1025}{12}\right)\right)^{84}}{\left(1+\left(\dfrac{0.1025}{12}\right)\right)^{84}-1}[/tex]
[tex]\implies \sf PMT = 634.9279215[/tex]
Therefore, the monthly payment is $634.93.
Part (c)Down payment = $3,000
⇒ P = $39,950 - $3,000 = $36,950
[tex]\implies \sf PMT=\dfrac{36950\left(\dfrac{0.1025}{12}\right)\left(1+\left(\dfrac{0.1025}{12}\right)\right)^{84}}{\left(1+\left(\dfrac{0.1025}{12}\right)\right)^{84}-1}[/tex]
[tex]\implies \sf PMT = 618.197278[/tex]
Therefore, the monthly payment is $618.20.
Part (d)Down payment = $5,000
⇒ P = $39,950 - $5,000 = $34,950
[tex]\implies \sf PMT=\dfrac{34950\left(\dfrac{0.1025}{12}\right)\left(1+\left(\dfrac{0.1025}{12}\right)\right)^{84}}{\left(1+\left(\dfrac{0.1025}{12}\right)\right)^{84}-1}[/tex]
[tex]\implies \sf PMT = 584.735991[/tex]
Therefore, the monthly payment is $584.74.

# Simplify the following using the law of indices :
[tex]2a \times 3a {}^{2} [/tex]
Simplifying the given value using the law of indices is 6[tex]a^{3}[/tex]
2a * 3[tex]a^{2}[/tex]
=6[tex]a^{3}[/tex]
Index laws are the rules for simplifying expressions involving powers of the same base number.
Here are the essential steps to follow to simplify an algebraic expression:
Remove parentheses by multiplying factors.
Use exponent rules to get rid of parentheses in terms with exponents.
Combine like terms by adding coefficients.
Combine the constants.

PLEASE HELP! DUE IN LESS THAN 2 HOURS! IM STUCK! I THINK THEY ARE ALL TRUE! WHAT ONE IS FALSE AND WHY! PLEASE HELP ME! YOU WILL GET 50 POINTS! THANKS QUESTION DOWN BELOW!!!
=====================================================
Reason:
Let's go through the four answer choices to see which are true and which are false. We'll rule out the ones that are true.
A) This is true. We can use inductive reasoning to form a conjecture. A conjecture is basically a generalized guess. For example, a guess would be something like "the sum of the first n odd numbers is n^2". So 1+3 = 4, 1+3+5 = 9, 1+3+5+7 = 16, 1+3+5+7+9 = 25, and so on. Does the pattern go on forever? Or does it stop at some point? That's why a proof is needed.B) This is true. See choice A.C) This is true. Some conjectures have been proven (such as the example I mentioned in choice A) while others have not. A famous unproven conjecture is Goldbach's Conjecture. D) This is false. Inductive reasoning helps form a conjecture, but it does not lead to definitive proof. We would need deductive reasoning.convert 3/7 to percent
The percentage is 42.8571%.
what is percentage?Percentage, a relative value indicating hundredth parts of any quantity. One percent is a hundredth part; thus, 100 percent represents the entirety and 200 percent specifies twice the given quantity.
All of something is 100 percent, half of it is fifty percent, none of something is zero percent. To determine a percentage, you divide the portion of the whole by the whole itself and multiply by 100.
Given fraction:
3/7
To convert the fraction into percentage we have multiply 100
3/7*100
=300/7
= 42.8571%
Hence, the percentage of fraction 3/7 is 42.8571%.

Answer:
[tex]\sf \dfrac{3}{4}[/tex]
Step-by-step explanation:
Given expression:
[tex]\implies \sf \left(\dfrac{-4}{9} \times \dfrac{63}{28}\right)-\left(\dfrac{33}{66} \times \dfrac{-51}{17}\right)+\left(\dfrac{5}{8} \times \dfrac{4}{10}\right)[/tex]
[tex]\textsf{Apply the fraction rule} \quad \dfrac{a}{b} \times \dfrac{c}{d}=\dfrac{a \times b}{c \times d}:[/tex]
[tex]\implies \sf \left(\dfrac{-4\times63}{9\times28} \right)-\left(\dfrac{33 \times -51}{66 \times 17}\right)+\left(\dfrac{5\times4}{8\times10} \right)[/tex]
Multiply the numbers:
[tex]\implies \sf \left(\dfrac{-252}{252} \right)-\left(\dfrac{-1683}{1122}\right)+\left(\dfrac{20}{80} \right)[/tex]
Reduce the fractions:
[tex]\implies \sf -1-\left(\dfrac{-3}{2}\right)+\left(\dfrac{1}{4} \right)[/tex]
[tex]\textsf{Apply rule}\quad \:a-\left(-b\right)=a+b:[/tex]
[tex]\implies \sf -1+\dfrac{3}{2}+\dfrac{1}{4}[/tex]
Adjust the fractions based on the LCM of 4:
