Add a term to the expression so tha it becomes a perfect square trinomial. Y^2-13y+
Answers
The term that should be added to the expression to make the expression perfect square trinomial is 169/4. The expression then becomes : (y - 13/2)²
What is meant by a perfect square trinomial?
By multiplying a binomial by another binomial, perfect square trinomials—algebraic equations with three terms—are created. A number can be multiplied by itself to produce a perfect square. Algebraic expressions known as binomials are made up of simply two words, each of which is separated by either a positive (+) or a negative (-) sign. Similar to polynomials, trinomials are three-term algebraic expressions.
A perfect square trinomial expression can be created by taking the binomial equation's square. If and only if a trinomial satisfying the criterion b² = 4ac has the form ax² + bx + c, it is said to be a perfect square.
Given expression y² - 13y + ?
Comparing with the general equation
a = 1
b = -13
For perfect square trinomial
b² = 4ac
(-13)² = 4 * 1 * c
169 = 4c
c = 169/4
So the expression becomes,
y² - 13y + 169/4 = (y - 13/2)²
Therefore the term that should be added to the expression to make the expression perfect square trinomial is 169/4.

Which equation would we use to figure out this problem? Rachael
started off with $400 in her savings account in 2005. It earns 3% interest
each year. She wants to know how much money she'll have in the account
in 2022.
Answers
Answer:
She'll have $661 in the account in 2022.
Step-by-step explanation:
Compound interest:
The amount of money earned in compound interest after t years is given by the following equation:
\(A(t) = A(0)(1+r)^t\)
In which A(0) is the initial amount and r is the interest rate, as a decimal.
Rachael started off with $400. It earns 3% interest each year.
This means that \(A(0) = 400, r = 0.03\)
So
\(A(t) = A(0)(1+r)^t\)
\(A(t) = 400(1+0.03)^t\)
\(A(t) = 400(1.03)^t\)
She wants to know how much money she'll have in the account in 2022.
17 years after 2005, which means that this is A(17). So
\(A(17) = 400(1.03)^{17} = 661\)
She'll have $661 in the account in 2022.

How much of each type should be used to make a 26 pound blend that sells for $10.00 per pound?
Answers
Let x be the number of pounds of Kenyan coffee and y be the number of pounds of Sumatran coffee. We know that x + y = 26 and 9x + 11y = 260.
Solving the system of equations, we get
x = 14 and y = 12
Therefore, the Coffee Counter should use 14 pounds of Kenyan coffee and 12 pounds of Sumatran coffee to make a 26 pound blend that sells for $10.00 per pound.
To confirm, the average price of the blend is: (9*14 + 11*12) / 26 = 10.00
So the answer is 14,12

Answers
Answer:
The two quantitative elements of process variation are:
a. common cause and special cause.
Step-by-step explanation:
When a process fails to follow the prescribed process pattern, with reduced productivity, higher costs, longer lead times, and late deliveries, a process variation has occurred. Thus, process variation is a leading cause of quality issues. There are common cause variation, which is inherent in the system itself, and special cause variation, which is caused by external factors outside of the system. Process variations can be reduced by reducing the common and special cause variations, among other steps.

Describe what the graph of the proportional relationship would look like.
O Aline passes through the point (0, 0) and continues through the point (3, 12).
O Aline passes through the point (0, 0) and continues through the point (2,8).
A line passes through the point (0, 0) and continues through the point (6, 24).
A line passes through the point (0, 0) and continues through the point (12, 3).
Question 2(Multiple Choice Worth 2 points)
(Graphing Proportional Relationships MG)
Answers
The correct answer is option D: A line passes through the point (0, 0) and continues through the point (12, 3)
For the first question:
The table shows a proportional relationship between x and y. To describe what the graph of this proportional relationship would look like, we can examine the given data points.
The data points are (12, 3), (8, 26), and (24, ?). We can observe that as x increases, y also increases. This indicates a positive correlation between the variables. Additionally, we can see that the ratio of y to x remains constant for each data point.
Now, let's analyze the answer options:
A. A line passes through the point (0, 0) and continues through the point (3, 12).
This answer option does not align with the given data because there is no data point with an x-value of 3 and a corresponding y-value of 12.
B. A line passes through the point (0, 0) and continues through the point (2, 8).
This answer option aligns with the given data because (2, 8) is a valid data point from the table, and the line passes through the origin (0, 0).
C. A line passes through the point (0, 0) and continues through the point (6, 24).
This answer option does not align with the given data because there is no data point with an x-value of 6 and a corresponding y-value of 24.
D. A line passes through the point (0, 0) and continues through the point (12, 3).
This answer option aligns with the given data because (12, 3) is a valid data point from the table, and the line passes through the origin (0, 0).
Based on the analysis, the correct answer is option D: A line passes through the point (0, 0) and continues through the point (12, 3). This accurately represents the graph of the proportional relationship given in the table.

The triangles are similar.
Explanation:
Similar triangles have 3 pairs of congruent angles. In this diagram, we can see that the triangles WXP and WYZ share angle W, which is congruent to itself; therefore, they have at least 1 pair of congruent angles. We are given that angle X is congruent to angle Y, so that is a second pair of congruent angles. Finally, we know that angle P is congruent to angle Z because if two pairs of corresponding angles are congruent, then the third pair must also be congruent because the measures of the interior angles of both triangles have to add to 180°.
Math! Who’s knows the answer?
Answers
Answer:
M=30 degrees
because 102+148=150 and 180-150=30. (remember the sum of a triangle is 180 degrees)
the congruence statement would be SAS (side angle side) because 102 and 48 are the same in both triangles, but the third side is not the same.
The length of a rectangle is four times its width. If the perimeter of the rectangle is 180 ft, find its area
Answers
The area of the rectangle is 1296 square feet.
Let's denote the width of the rectangle as "w" and its length as "4w" since the length is four times the width.
The formula for the perimeter of a rectangle is given by:
P = 2(l + w), where P is the perimeter, l is the length, and w is the width.
Given that the perimeter of the rectangle is 180 ft, we can write the equation as:
180 = 2(4w + w)
Simplifying the equation:
180 = 2(5w)
180 = 10w
w = 18
So, the width of the rectangle is 18 ft.
Now, we can find the length of the rectangle:
Length = 4w = 4(18) = 72 ft
The area of a rectangle is given by the formula:
\(A = l \times w,\)
where A is the area,
l is the length,
and w is the width.
Substituting the values we found:
Area \(= 72 ft \times 18 ft = 1296 ft^2\)

How much is 78 divided by 4
19
19R1
19R2
19R3
Answers
Answer:
C) 19, remainder 2
Step-by-step explanation:
Divide 78 by 4
78/4 = 19.5, or 19R2
The result of 78 divided by 4 is 19 with a remainder of 2, option C is correct.
When you divide 78 by 4, divide the leftmost digit (7) by 4.
4 can go into 7 one time, so the first digit of the quotient is 1.
Then, you multiply the quotient digit (1) by the divisor (4) and subtract the result from the original number.
7 - (1 × 4)
= 7 - 4
= 3
You then bring down the next digit from the original number, which is 8, and divide it by the divisor (4) again.
Now, you divide 38 by 4. 4 can go into 38 nine times, so the second digit of the quotient is 9.
Multiply the quotient digit (9) by the divisor (4) and subtract the result from the remaining part of the original number.
38 - (9×4)
= 38 - 36
= 2
There are no more digits left in the original number to bring down.
The remainder is 2 because there is still some value left that cannot be divided evenly by 4.

To find:
The probability that a 4 will come up exactly twice = ?
Solution:
Let 4 comes up exactly twice, let the third number be \(x\).
The possible outcomes can be:
(\(x\), 4, 4) where \(x\) can be any number between 1 to 6 , so 6 outcomes.
(4, \(x\), 4) where \(x\) can be any number between 1 to 6 , so 6 outcomes.
(4, 4, \(x\)) where \(x\) can be any number between 1 to 6 , so 6 outcomes.
So, the total number of favorable outcomes possible = 6 + 6 + 6 = 18
Total number of outcomes that can be possible at roll of 3 dice:
6 \(\times\) 6 \(\times\) 6 = 216
Formula for probability of an event E is given as:
\(P(E) = \dfrac{\text{Number of favorable cases}}{\text {Total number of cases}}\)
