Answer:
there is no value of v that makes quadrilateral PQRS a parallelogram.
Step-by-step explanation:
Hopefully this helps, may be wrong so...
A quadrilateral is a parallelogram if and only if opposite angles are equal. Therefore, in order for quadrilateral PQRS to be a parallelogram, angle P must be equal to angle S, and angle Q must be equal to angle R. From the given information, we know that:
angle P = v + 38°
angle S = 8v - 56°
angle Q = v + 98°
angle R = 6v - 72°
To find the value of v that makes quadrilateral PQRS a parallelogram, we must set angle P equal to angle S and angle Q equal to angle R:
v + 38° = 8v - 56°
v + 98° = 6v - 72°
Solving for v in the first equation:
v + 38° = 8v - 56°
-7v = -94°
v = 13.428571428571429
Solving for v in the second equation:
v + 98° = 6v - 72°
-5v = -170°
v = 34
We can see that both values of v do not match, therefore there is no value of v that makes quadrilateral PQRS a parallelogram.
A quadrilateral is a parallelogram if and only if the opposite angles are equal. In this case, the opposite angles are P and S, and Q and R.
Therefore, for the quadrilateral PQRS to be a parallelogram, we must have:
v+38° = 8v-56° and v+98° = 6v–72°
Solving the first equation for v:
v+38° = 8v-56°
38 = 7v
v = 38/7
Now we use this value of v to check if the second equation is true:
v+98° = 6v–72°
(38/7) +98 = 6(38/7) - 72
98 = -34
As we can see, the second equation is not true, so the value of v = 38/7 doesn't make quadrilateral PQRS a parallelogram.
No value of v exists that would make quadrilateral PQRS a parallelogram, as the opposite angles are not equal in this case.

Why do you think insurance companies offer uninsured/ underinsured coverage at a cheaper rate than collision coverage?
We can actually think that insurance companies offer uninsured/ underinsured coverage at a cheaper rate than collision coverage because the risk of a claim is typically lower for uninsured/underinsured coverage.
What is insurance?An agreement to provide compensation to another party in the event of a certain loss, damage, or injury is known as insurance, and it is a way to safeguard against financial loss. It is a type of risk management that is mostly applied to protect against the risk of a potential or unforeseen loss.
Collision coverage is for damage to the policyholder's own vehicle, while uninsured/underinsured coverage is for damage caused by another driver who does not have enough insurance to cover the costs of an accident. Since fewer drivers are uninsured or underinsured, the likelihood of a claim being made under that coverage is lower, and thus the cost is less.

A square has sides that measure 8x + 5 inches. A rectangle has two sides that measure 4x - 5 inches and two sides that measure 12x + 15 inches.
For what value of x will the perimeters of the square and rectangle be the same?
Answer:
The perimeter of the square is 32x + 20 inches, and the perimeter of the rectangle is (4x - 5) + (4x - 5) + (12x + 15) + (12x + 15) = 32x + 20 inches.
So, to find the value of x that makes the perimeters the same, we set 32x + 20 = 32x + 20 and solve for x.

I just need help with number 2 on box A. I can record the coordinates of the triangle.
The coordinates of the ends of the image are J'(x, y) = (- 7, 7), K'(x, y) = (- 5, 2) and L'(x, y) = (- 2, 3), whose transformation formula is P'(x, y) = P(x, y) + (0, - 2 · p). A representation of the figures is in the image shown below.
How to derive the reflection formula of a figure
In this problem we find a geometric locus generated by three points on Cartesian plane that is reflected over the x-axis, whose formula is shown below:
P'(x, y) = P(x, y) + (0, - 2 · p)
Where:
P(x, y) - Original pointP'(x, y) - Resulting pointp - y-Coordinate of the original point.If we know that J(x, y) = (- 7, - 7), K(x, y) = (- 5, - 2) and L(x, y) = (- 2, - 3), then the coordinates of the image are:
J'(x, y) = (- 7, - 7) + (0, 14)
J'(x, y) = (- 7, 7)
K'(x, y) = (- 5, - 2) + (0, 4)
K'(x, y) = (- 5, 2)
L'(x, y) = (- 2, - 3) + (0, 6)
L'(x, y) = (- 2, 3)

5/8 + 3/5 greater than 1
Answer: Yes
Step-by-step explanation:
First You need to find a common denominator between 5/8 and 3/5 so you can add them together.
The earliest common denominator between 8 and 5 is 40.
So you have to Multiply the numerator by whatever it takes the denomintor to reach 40.
So for 8 to reach 40 you have to multiply 8 by 5 so you must also multiple the numerator by 5 giving you 25 so your fraction becomes 25/40.
If you do the same for the other fraction you end with 24/40.
so 25/40 + 24/40 = 49/40 which is greater than 1

2. A person has a beginning balance of $660. She pays $90 on the ninth day, and she charges $320 on the 28th day. What amount of interest is due on her account if it has an APR of 26 percent?
The amount of interest due on the account is $8.36.
What is the simple interest?The interest on a loan or deposit can be calculated using simple interest. In order to calculate it, multiply the principal amount by the interest rate and then by the number of time periods (usually in years).
We must first determine the number of days for which the interest will accrue in order to calculate the amount of interest owed on the account. Since the charge was made on the 28th day after the payment was made on the 9th day, the interest will accrue for 19 days instead of the 28 since the payment was made.
We then use the formula for simple interest: Interest = Principal x Rate x Time
In this instance, the Principal is the initial balance of $660, the Rate is the annual percentage rate (APR), which needs to be converted to decimal form by dividing by 100, and the Time is the total number of days over which interest will accrue (19 days).
The Interest = $660 × 0.26 × (19/365) = $8.36
Thus, the total amount of interest due on the account is $8.36.

When you know the tower's height, you may calculate your distance from it.The answer is 92.54 feet .
Determine the height of the tower ?When you know the tower's height, you may calculate your distance from it.The tangent of the angle of elevation multiplied by the horizontal distance, or doing the calculation, is all that is required to manually determine the height.
30° vertical angle from A to the tower's summit
50 + x is the horizontal separation between A and the tower's base.
Call h to get the tower's height.
tan 30 = h / (50 + x) => 50 + x = h / tan 30 => x = h / tan 30 - 50 (1)
40° vertical angle from B to the tower's summit
The tower's base is x feet away from B in a horizontal direction.

3. Model Real Life A beehive has 9,268 fewer drone
bees than worker bees. There are 651 drone bees
in the beehive. How many worker bees are in the
beehive?
If the number of drone bees in the beehive is 9,268 fewer than the number of worker bees, we can set up an equation to represent the relationship:
Drone bees = Worker bees - 9,268
We know that there are 651 drone bees in the beehive, so we can substitute that value into the equation:
651 = Worker bees - 9,268
To find the number of worker bees, we need to solve for Worker bees. To do this, we need to add 9,268 to both sides of the equation:
651 + 9,268 = Worker bees
Worker bees = 9,919
So, there are 9,919 worker bees in the beehive.

the fed is most likely to use which tool(s) to conduct monetary policy? group of answer choices open market operations discount rate interest on reserves (ior) rate required reserve ratio
The Federal Reserve uses three main tools to conduct monetary policy: Open Market Operations, the Discount Rate, and Interest on Reserves (IOR).
Open Market Operations involve the buying and selling of government securities in the open market, which impacts the money supply and interest rates. The Discount Rate is the interest rate the Federal Reserve charges commercial banks to borrow from it. A lower Discount Rate encourages borrowing, while a higher Discount Rate discourages borrowing. Interest on Reserves (IOR) is the interest rate the Federal Reserve pays commercial banks on their excess reserves. A higher IOR rate encourages banks to keep more of their funds in the form of reserves, while a lower IOR rate encourages banks to lend out more of their funds. The Required Reserve Ratio is also used to affect the money supply, as it determines the amount of reserves banks must keep on hand. An increase in the Required Reserve Ratio reduces the money supply, while a decrease in the Required Reserve Ratio increases the money supply.

The graph of f(x) = 3x is a vertical stretch with a factor of 3 of the graph of the parent function f(x) = x.
How to describe the transformation?The parent function for this problem is defined as follows:
f(x) = x.
The transformed function is given as follows:
f(x) = 3x.
The only transformation is a multiplication by the constant 3. As the constant has an absolute value greater than 1, the graph of f(x) = 3x is a vertical stretch with a factor of 3 of the graph of the parent function f(x) = x.
Missing InformationThe problem asks for how the graph of f(x) = 3x compares to the graph of f(x) = x.

which of the following is true of a scientific theory? view available hint(s)for part a which of the following is true of a scientific theory? it generates testable hypotheses, is supported by a large body of evidence, and is broad in scope. it is only accepted after the person who formulated it has died. it is formulated by many scientists over drinks at a convention. it is a method or device that applies scientific knowledge for some specific purpose. it must demonstrate the effect of one variable by testing control groups and experimental groups.
Out of the following, the statement is It generates testable hypotheses, is supported by a large body of evidence, and is broad in scope is true of a scientific theory.
A scientific theory is a well-substantiated explanation of some aspect of the natural world that is acquired through the scientific method and repeatedly tested and confirmed through observation and experimentation. A scientific theory is not just an idea or speculation. It is a systematic way of organizing and interpreting observations that are based on facts and evidence. It is also open to being tested and disproved if new evidence arises.
A scientific theory must be supported by a large body of evidence from multiple sources to be considered valid. Furthermore, a scientific theory must be broad in scope and explain a wide range of phenomena. It must also generate testable hypotheses that can be tested and verified through experimentation and observation.
A scientific theory is not accepted until it is thoroughly tested and confirmed through numerous experiments and observations. Therefore, it is not accepted after the person who formulated it has died.

solve this system of equations by using the elimination method.
2x+6y=2 2x+2y=2
Answer: The elimination method is a method for solving a system of equations by eliminating one of the variables. One way to do this is to multiply one equation by a constant and then add or subtract it from the other equation to cancel out one of the variables.
We will start by multiplying the first equation by 3:
2x + 6y = 2 ----> 6x + 18y = 6
Now we will subtract the second equation from the modified first equation:
6x + 18y = 6
(2x + 2y = 2)
4x + 16y = 4
Now we can solve for one of the variables, we will solve for x:
4x = 4
x = 1
Now that we know x = 1, we can substitute this back into one of the original equations, for example the first one:
2x + 6y = 2
2(1) + 6y = 2
6y = 0
y = 0
So the solution to the system of equations is x = 1 and y = 0
Therefore, the solution is (1,0)
Step-by-step explanation:
Alexandra invested 40% of his money in mutual funds, 40% in real estate, and 20% in stocks. If the value of the money that he invested in mutual funds, real estate, and stocks grew by 2%, 7%, and 11% respectively, what was the average growth on his total investment?
Answer:
To find the average growth on Alexandra's total investment, we need to calculate the weighted average of the growth in each of the three investments. The weighted average is calculated by multiplying the growth of each investment by its proportion of the total investment and then adding them together.
First, we need to calculate the total amount of money that Alexandra invested. Since he invested 40% in mutual funds, 40% in real estate, and 20% in stocks, we can assume he invested $100.
So the amount invested in mutual funds is 40/100 * $100 = $40
The amount invested in real estate is 40/100 * $100 = $40
The amount invested in stocks is 20/100 * $100 = $20
Then we can calculate the growth of each investment using the percentages provided:
The growth of mutual funds is 2/100 * $40 = $0.80
The growth of real estate is 7/100 * $40 = $2.80
The growth of stocks is 11/100 * $20 = $2.20
Now we can add up the growth of each investment and divide it by the total investment to find the average growth:
($0.80 + $2.80 + $2.20) / $100 = $5.80 / $100 = 0.058 or 5.8%
So the average growth on Alexandra's total investment is 5.8%.
