To borrow money, you pawn your guitar. Based on the value of the guitar, the pawnbroker loans you $960. One month later, you get the guitar back by paying the pawnbroker $1,472. What annual interest rate did you pay? Round to the nearest tenth of a percent. ...?
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.

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.

Identify the type of conic section that has the equation 9x^2+ 16y^2 = 144 and identify its domain and range.
Answer:
B ) ellipse.Domain: { -4 ≤ x ≤ 4 }Range: { -3 ≤ y ≤ 3 }
posted whole test on jiskha under RandomSophomore
The equation [tex]\(9x^2 + 16y^2 = 144\)[/tex] represents an ellipse. Its domain is \([-4, 4]\) and its range is \([-3, 3]\).
The equation [tex]\(9x^2 + 16y^2 = 144\)[/tex] represents an ellipse. To identify its domain and range, we need to understand its shape and orientation.
Step 1: Standard Form of an Ellipse
The standard form of an ellipse with its center at the origin is [tex]\( \frac{x^2}{a^2} + \frac{y^2}{b^2} = 1 \)[/tex], where \( a \) and \( b \) are the semi-major and semi-minor axes lengths, respectively.
Step 2: Compare Equations
Comparing the given equation [tex]\( 9x^2 + 16y^2 = 144 \)[/tex] with the standard form, we see that [tex]\( a^2 = \frac{144}{9} = 16 \)[/tex] and [tex]\( b^2 = \frac{144}{16} = 9 \).[/tex]
Step 3: Determine Axis Lengths
This means the semi-major axis length \( a \) is [tex]\( \sqrt{16} = 4 \)[/tex]and the semi-minor axis length \( b \) is [tex]\( \sqrt{9} = 3 \).[/tex]Step 4: Shape of the Ellipse
Since \( a > b \), the ellipse is stretched more horizontally than vertically, meaning it's wider than it is tall.
Step 5: Domain and Range
The domain of the ellipse is determined by the values of \( x \) and the range by the values of \( y \). For this ellipse, the \( x \)-values vary from \( -4 \) to \( 4 \) (domain), and the \( y \)-values vary from \( -3 \) to \( 3 \) (range).
Therefore, the domain is \([-4, 4]\) and the range is \([-3, 3]\).

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.

If ABCDE is a regular pentagon and diagonals EB and AC intersect at O, then what is the degree measure of angleEOC?
If ABCDE is a regular pentagon and diagonals EB and AC intersect at O, then the degree measure of angle EOC is 108°.
In Mathematics and Geometry, the sum of the interior angles of both a regular and irregular polygon is given by this formula:
Sum of interior angles = 180 × (n - 2)
Note: The given geometric figure (regular polygon) represents a pentagon and it has 5 sides.
Sum of interior angles = 180 × (5 - 2)
Sum of interior angles = 180 × 3
Sum of interior angles = 540°.
Therefore, the measure of each interior angle is given by;
Interior angle of a pentagon = 540°/5
Interior angle of a pentagon = 108°
From triangle EAO, we have:
2m∠EOA = 180° - (54 + 54)°

Which ratio is equal to b:q? (1 point)
b:a
c:r
r:a
q:c
∆ABC~∆PQR
AB~PQ , c~r
c:r
Answer:
The correct option is 2.
Step-by-step explanation:
It is given that triangles ABC and PQR are similar triangles.
The sides of the triangle ABC are AB = c, BC = a, and AC = b. Triangle PQR has sides PQ = r, QR=p and PR=q.
If two triangles are similar, then their corresponding sides proportional.
Since ABC and PQR are similar triangles, therefore
[tex]\frac{AB}{PQ}=\frac{BC}{QR}=\frac{AC}{PR}[/tex]
[tex]\frac{c}{r}=\frac{a}{p}=\frac{b}{q}[/tex]
It can be written as
[tex]\frac{c}{r}=\frac{b}{q}[/tex]
[tex]\frac{a}{p}=\frac{b}{q}[/tex]
Therefore b:q is equal to c:r or a:p. Option 2 is correct.

Marquis has a gross pay of $816. By how much will his gross pay be reduced if Marquis has the following items withheld?
federal tax of $92
Social Security tax that is 6.2% of his gross pay
Medicare tax that is 1.45% of his gross pay
state tax that is 22% of his federal tax
Answer:
His gross pay would be reduced $174.66.
Step-by-step explanation:
Gross pay of Marquis = $816
His withholding are :
Federal tax = $92.00
Social security tax = 6.2% of $816
= 0.062 × 816
= $50.592
Medicare tax = 1.45% × 816
= 0.0145 × 816
= $11.832
State tax = 22% × 92
= 0.22 × 92
= $20.24
Total withholding = 92 + 50.59 + 11.83 + 20.24
= $174.66
His net pay = $816 - $174.66 = $641.34
His gross pay would be reduced $174.66
