The annual interest rate paid for the pawned guitar is calculated to be 640%, which is obtained by dividing the interest paid by the original loan amount to find the monthly rate and then multiplying by 12.
Explanation:To calculate the annual interest rate paid for pawning the guitar, we need to first determine the total interest paid, then the monthly interest rate, and finally convert that to an annual rate. The interest paid is the difference between the amount received from pawning the guitar and the amount paid to redeem it, which is $1,472 - $960 = $512.
As the loan was for one month, we can determine the monthly interest rate by dividing the interest paid by the principal amount. This gives us $512 / $960 = 0.5333 or 53.33%. To find the annual interest rate, we multiply the monthly rate by 12 (the number of months in a year). Thus, the annual interest rate is 53.33% * 12 = 640%.
It's important to note that this is an extremely high rate of interest, which is not uncommon for pawnshop loans or other short-term high-risk loans.

When n = energy efficiency and Pin = energy input and Pout = energy output, how can you mathematically represent the correct relationship between the energy you put in something and the energy you get out?
A. n = P out * P in
B. n = P out / P in
C. n = P out - P in ...?
Answer:
[tex]n=\frac{P_{out}}{P_{in}}[/tex]
Step-by-step explanation:
We know that,
[tex]\text{Energy efficiency}=\frac{\text{Energy out put}}{\text{Energy in put}}[/tex]
If [tex]P_{in}[/tex] represents the energy input,
[tex]P_{out}[/tex] represents the energy output,
And, n represents energy efficiency,
Hence, the required formula would be,
[tex]n=\frac{P_{out}}{P_{in}}[/tex]

HELP ME ASAP!! Some red white and blue candies were placed in a bowl. Some contain nuts, and some do not. Suppose one of the candies were chosen randomly from all the candies in the bowl. According to the table below, if the candy is blue, what is the probability that is does not contain any nuts?
Red with nuts=10. Red without nuts=10. White with nuts=20. White without nuts=10. Blue with nuts=20. Blue without nuts=30.
A. 20%
B. 40%
C. 60%
D. 10%
Answer:
Option C: 60%
Step-by-step explanation:
The number of blue candies with nuts = 20
The number of blue candies without nuts = 30
The total number of blue candies = 20 + 30 = 50
As the chosen candy is blue, the probability that is does not contain any nuts will be = (The number of blue candies without nuts)/(Total number of blue candies)
So, the probability = 30/50 = 0.6 *100% = 60%

A florist shop represents its first month’s sales with the equation y=168x+8, where x represents the number of days that the shop is open and y represents the sales in dollars. The owner of the shop would like to calculate the number of days it took to reach $3,200 in sales. Which would be used to solve the problem?
A-Substitute 3,200 for x.
B-Add 8 and 3,200.
C- Divide 3,192 by 168.
D-Isolate y in the equation.
Answer:
Option C is the answer.
Step-by-step explanation:
A florist sale is for it's first month is represented by the equation y = 168x + 8
Here y represents the sales in dollars and x represents number of days.
Now we have to calculate the number of days it took to reach $3200 in sales.
For this we will substitute $3200 in place of y and find the value of x by solving the equation.
3200 = 168x + 8
168x = 3200 - 8 = 3192
[tex]x=\frac{3192}{168}=19[/tex]
Therefore Option C. is the correct option.

Determine whether the following relation is a function.
{(3,7), (3,8), (3,-2), (3.4),(3,1)}
A) it is a function because the ordered pairs all have the same x-value.
B) it is not a function because there are multiple y-values paired with a single x-value.
C) it is a function because none of the ordered pairs have the same y-value.
D) it is not a function because none of the ordered pairs have the same y-value.
The relation is not a function it is not a function because there are multiple y-values paired with a single x-value. Option B.
Is the relation a function?A relation is a function only if every input is mapped into a single output.
Here we have the relation {(3,7), (3,8), (3,-2), (3.4),(3,1)}
Remember that the first number of each pair is the input, so we can see that all the inputs are the same one
So the input x = 3 is mapped into different outputs, thus, this is not a function.

The correct option is B) it is not a function because there are multiple y-values paired with a single x-value.
To determine if a relation is a function, one must check if each x-value is associated with exactly one y-value. In other words, for every x, there should be one and only one y. This is known as the vertical line test in the context of graphs.
Let's examine the given set of ordered pairs: {(3,7), (3,8), (3,-2), (3,4), (3,1)}.
We can see that the x-value of 3 is repeated with different y-values: 7, 8, -2, 4, and 1.
This means that the x-value of 3 is associated with multiple y-values, which violates the definition of a function.
Therefore, the relation is not a function because it fails to satisfy the condition that each x-value must correspond to exactly one y-value.
The presence of multiple y-values for a single x-value is the key indicator that the relation is not a function.

What is the smallest positive value for x where y=sin2x reaches its maximum? How do you figure this out? ...?
To find the smallest positive value for x where y = sin^2x reaches its maximum, we can set sin^2x = 1 and solve for x. The smallest positive value of x where y = sin^2x reaches its maximum is pi/2.
Explanation:To find the smallest positive value for x where y = sin^2x reaches its maximum, we need to consider the properties of the sine function. The sine function oscillates between -1 and +1, with the maximum value of sin^2x being 1. Since the maximum value of sin^2x is 1, we can set sin^2x = 1 and solve for x.
Applying the property of sin^2x = 1, we have:
sin^2x = 1
Taking the square root of both sides, sinx = ±1
Since we are looking for the smallest positive value of x, we take sinx = 1
This means that x = π/2 + 2πn, where n is an integer.
Therefore, the smallest positive value for x where y = sin^2x reaches its maximum is π/2.

What is the negative reciprocal of 3/4 or three over 4
Final answer:
The negative reciprocal of 3/4 is -4/3. This is found by inverting the fraction to get 4/3 and then applying the negative sign.
Explanation:
The negative reciprocal of a number refers to the value that, when multiplied by the original number, results in -1. For the fraction 3/4 (three over four), taking the reciprocal involves flipping the numerator and the denominator, which gives us 4/3. Making this reciprocal negative results in -4/3. The concept of reciprocals relates to the broader mathematical principles of multiplication and division, where negative exponents indicate the inverse of the corresponding positive exponent. For example, x to the power of -1 is equal to 1 divided by x to the power of 1, which demonstrates how negative exponents introduce division into the operation.
8 less than a number n is less than 11
Final answer:
To find the number n in the inequality '8 less than a number n is less than 11', we can set up and solve the inequality n - 8 < 11. The answer is that the number n is less than 19.
Explanation:
The question states that 8 less than a number n is less than 11. To solve this, we can set up the inequality:
n - 8 < 11
To isolate n, we can add 8 to both sides:
n < 11 + 8
n < 19
So, the answer is that the number n is less than 19.
