One figure models 1/4 as 4 of 12 equal parts of a whole. The other models 1/3 as 1 of 3 equal parts of a whole. What is true about the equal parts for the two fractions?
The correct option for this questions is Option C
Equivalent Fractions for 4/12:
1/3, 2/6, 3/9, 4/12, 5/15, 6/18, 7/21, 8/24, 9/27, 10/30, 11/33, 12/36, 13/39, 14/42, 15/45, 16/48, 17/51, 18/54, 19/57, 20/60, and so on ...
How do you find equivalent fractions?Two frations are equivalent when they have the same value when written in lowest terms. The fraction 8/24 is equal to 1/3 when reduced to lowest terms. To find equivalent fractions, just multiply the numerator and denominator of that reduced fraction (1/3) by any interger number, ie, multiply by 2, 3, 10, 30.
2/6 is equivalent to 4/12 because 1 x 2 = 2 and 3 x 2 = 63/9 is equivalent to 4/12 because 1 x 3 = 3 and 3 x 3 = 94/12 is equivalent to 4/12 because 1 x 3 = 4 and 3 x 3 = 12Equivalent fractions may look different, but when you reduce then to the lowest terms you will get the same value. If any fraction is not reduced to lowest terms, you can get other equivalent fractions just dividing both numerator and denominator by the same number.
Thus, option c is your answer

Find the present value of a sequence of annual payments of Rs 25000 each , the first being made at the end of 5th year and the last being paid at the end of 12th year, if money is worth 6%.
The present value of the sequence of annual payments of Rs 25000 each, the first being made at the end of the 5th year and the last being paid at the end of the 12th year, if money is worth 6% is Rs. 158620.39.
1: We can use the formula to calculate the present value of the annuity:
P = A x [1 - (1+i)^-n] / i
Where
P = Present Value
A = Annuity
i = Interest Raten = Number of payments
2: Calculate the present value of each payment using the formula:
P1 = 25000 / (1.06)⁵
P2 = 25000 / (1.06)⁶
P3 = 25000 / (1.06)⁷
P4 = 25000 / (1.06)⁸
P5 = 25000 / (1.06)⁹
P6 = 25000 / (1.06)¹⁰
P7 = 25000 / (1.06)¹¹
P8 = 25000 / (1.06)¹²
3: Substitute the values into the formula to find the present value:
P = P1 + P2 + P3 + P4 + P5 + P6 + P7 + P8
P = (25000 / (1.06)⁵) + (25000 / (1.06)⁶) + (25000 / (1.06)⁷) + (25000 / (1.06)⁸) + (25000 / (1.06)⁹) + (25000 / (1.06)¹⁰) + (25000 / (1.06)¹¹) + (25000 / (1.06)¹²)
P = 158620.39

Ahlam bought goods worth $90. She gave the shopkeeper $100. The shopkeeper did not have exact balance. How much more should Ahlam give to the shopkeeper in order to get a balance of $25 ?
Ahlam needs to give the shopkeeper $15 more to get a balance of $25.
Word problems in MathematicsWord problems in Mathematics are mathematical approaches we make use of in our ongoing day to day activities. Algebra leading to word problems usually consist of numbers, variables, and its arithmetic operations.
Ahlam bought goods worth = $90, If she gave the shopkeeper $100, then she will collect $100 - $90 = $10 back.
But if the shopkeeper did not have an exact balance and Ahlam decided to give the shopkeeper $x to get a balance of $25.
Then we can write the expression as:
10 + x = 25
x = 25 - 10
x = 15
Therefore, we can conclude that Ahlam needs to give the shopkeeper $15 more to get a balance of $25.

A mathematics competition uses the following scoring procedure to discourage students from guessing (choosing an answer randomly) on the multiple-choice questions. For each correct response, the score is 7. For each question left unanswered, the score is 2. For each incorrect response, the score is 0. If there are 5 choices for each question, what is the minimum number of choices that the student must eliminate before it is advantageous to guess among the rest?
(A) 0
(B) 1
(C) 2
(D) 3
(E) 4
Please include the procedure
The minimum number of choices in a scoring procedure that the student must eliminate before it is advantageous to guess among the rest is 4. Option E is the correct option.
Suppose that there are n choices remaining for a particular question.
The probability of answering this question correctly is 1/n if the student guesses and the probability of leaving the question unanswered is (n-1)/n.
The expected score for guessing is therefore (7/n) × (1/n) + (2/n) × ((n-1)/n) = (7 + 2(n-1))/n² = (9 - 2/n)/n.
The expected score for leaving the question unanswered is 2/n.
The student should guess if and only if the expected score for guessing is greater than the expected score for leaving the question unanswered.
That is, we must have (9 - 2/n)/n > 2/n, or equivalently 9 > 2n, or n < 4.5.
Thus, if the number of choices remaining is 4 or more, the student should not guess; if the number of choices remaining is 3 or fewer, the student should guess.

The probability that the speed is less than 80 kmph is 0.1587 (rounded to four decimal places).
The average speed of a car on the highway is 85 kmph with a standard deviation of 5 kmph.
Assume the speed of the car, x, is normally distributed.
The probability that the speed is less than 80 kmph is required.
We will use the Z-score formula to solve this problem.
Z-score formula:
Z = (X - μ) / σWhereX = 80 (the speed we are interested in)
μ = 85 (mean of the normal distribution)
σ = 5 (standard deviation of the normal distribution)
Z = (80 - 85) / 5 = -1
The Z-score for the speed of 80 kmph is -1.
Using the standard normal distribution table,
we find that the probability that the Z-score is less than -1 is 0.1587 (rounded to four decimal places).

C. If x > 20, then x > 30 ; False -Counterexample: x=25 and x < 30
D. If x > 30, then x > 20 ; True
The converse of the conditional statement "If x < 20, then x < 30" is "If x < 30, then x < 20."
The converse statement is not true, because there are values of x that are less than 30 but are greater than or equal to 20.
Therefore, the counterexample is: x = 27.
If x = 27, the statement "If x < 30, then x < 20" is false because 27 is less than 30 but not less than 20.

A hiker travels N35W from his home for 5km. A second hiker travels S25W for 8km. How far are the two hikers apart? PLEASE SOMEONE ANSWER IM BEGGING YOU
It’s trig btw
Let's approach the problem using trigonometry to find the angle of the triangle formed by the two hikers and their respective displacements.
The first hiker travels N35W, which means the angle between his displacement and the north direction is 35 degrees. Similarly, the second hiker travels S25W, so the angle between his displacement and the south direction is 25 degrees.
To find the angle between the two hikers, we can consider the angle formed at the point where their displacements meet. Since one displacement is towards the north and the other is towards the south, the angle formed at their meeting point is the sum of the angles mentioned above:
Angle = 35 degrees + 25 degrees = 60 degrees
Now, we have an isosceles triangle with two sides of equal length: 5 km and 8 km. The included angle between these sides is 60 degrees.
To find the distance between the two hikers (the remaining side of the triangle), we can use the Law of Cosines:
c^2 = a^2 + b^2 - 2ab * cos(angle)
Substituting the values:
c^2 = 5^2 + 8^2 - 2 * 5 * 8 * cos(60)
Simplifying the equation and calculating:
c^2 = 25 + 64 - 80 * cos(60)
c^2 = 89 - 80 * (1/2)
c^2 = 89 - 40
c^2 = 49
Taking the square root of both sides:
c = sqrt(49)
c = 7 km
Therefore, the two hikers are approximately 7 km apart.

Solving for q will give us the optimal quantity that maximizes the profit, a function that gives the total profit earned can be written as:
Profit(q) = (Revenue per item - Cost per item) * q
Assuming that the revenue and cost are functions of the quantity sold (q), the total profit can be calculated as follows:
Profit(q) = Revenue(q) - Cost(q)
To find the quantity which maximizes the profit, we can take the derivative of the profit function with respect to q and set it equal to zero, and then solve for q:
Profit'(q) = Revenue'(q) - Cost'(q) = 0
Solving for q will give us the quantity that maximizes the profit. However, without knowing the specific forms of the revenue and cost functions, we cannot write a specific profit function or find the quantity that maximizes the profit.
In general, the profit function can be written as:
Profit(q) = (Revenue per item - Cost per item) * q
where the revenue per item and cost per item are functions of q. To find the quantity that maximizes the profit, we need to differentiate the profit function with respect to q and set it equal to zero:
Profit'(q) = Revenue'(q) - Cost'(q) = 0

Use dot products to express y as a linear combination of the vectors in S.
To represent y as a linear combination of the vectors in S using dot products, we calculate the dot product of y with each vector in S and divide it by the squared length of the corresponding vector. The coefficients obtained from the dot products form the linear combination. The steps for each exercise are as follows:
Let S = {7, 20} and y = {-1, 0, 9}.
Dot product with the first vector: (-1)⋅7 = -7
Dot product with the second vector: 0⋅20 = 0
y = (-7/149)⋅7 + (0/400)⋅20 = (-7/149)⋅7
Let S = {3, 1, 2, 0, 9} and y = {5, 5, -1}.

Dot product with the second vector: 5⋅1 = 5
Dot product with the third vector: -1⋅2 = -2
Dot product with the fourth vector: 0⋅0 = 0
Dot product with the fifth vector: 9⋅9 = 81
y = (15/19)⋅3 + (5/26)⋅1 + (-2/14)⋅2 + (0/5)⋅0 + (81/186)⋅9
Let S = {-1, 0} and y = {1, 0}.
Dot product with the first vector: 1⋅(-1) = -1
Dot product with the second vector: 0⋅0 = 0
y = (-1/1)⋅(-1) + (0/1)⋅0 = -1
Let S = {5, 5, -1, -1} and y = {2, 1}.
Dot product with the first vector: 2⋅5 = 10
Dot product with the second vector: 1⋅5 = 5
Dot product with the third vector: 2⋅(-1) = -2
Dot product with the fourth vector: 1⋅(-1) = -1

Question 6 :
Janelle sells sandwiches She spends
$270 per sandwich on Ingredients and
then adds a 110% markup. What is the
selling price of one sandwich?
Answer:
$5.67
Step-by-step explanation:
$5.67
Markup refers to the amount added to the cost price to cover overheads and profit. So for example a 50% markup on a $10 product would mean adding 50% of $10 onto the sale price. As fractions can be written as decimals (50% = 0.5) and we are adding on the amount of markup to the initial cost we can also phrase this as 10 x 1.5 = 15
For your question, the markup would become 1.1 and the initial cost is 2.7, remembering we must add 1 to the markup to cover the initial cost
2.7 x 2.1 = 5.67
