James, Priya, and Siobhan work in a grocery store. James makes $7.00 per hour. Priya makes 40% more than James, and Siobhan makes 5% less than Priya. How much does Siobhan make per hour?
Siobhan makes $
per hour.
Answer:
The per hour income of Siobhan is $9.31 per hour.
Step-by-step explanation:
Working in a grocery store James makes $7.00 per hour. Priya's hourly income is 40% more than James, and Siobhan's hourly income is 5% less than Priya.
Therefore, using formula of percentage, the per hour income of Priya will be
[tex]7.00(1 + \frac{40}{100}) = 7 \times 1.4 = 9.8[/tex] dollars per hour.
Again, the per hour income of Siobhan is [tex]9.8(1 - \frac{5}{100}) = 9.8 \times 0.95 = 9.31[/tex] dollars per hour. (Answer)

Kendra took out a loan for $750 at an 8.4% APR, compounded monthly, to buy
a stereo. If she will make monthly payments of $46.50 to pay off the loan,
which of these groups of values plugged into the TVM Solver of a graphing
calculator could be used to calculate the number of payments she will have
to make?
O
O
A. N=;1% = 0.7; PV=-750; PMT=46.5; FV=0; P/Y=12; C/Y=12;
PMT:END
B. N=;1% = 0.7; PV=-750; PMT=46.5; FV=0; P/Y=1; C/Y=12;
PMT:END
C. N=;1% = 8.4; PV=-750; PMT=46.5; FV=0; P/Y=1; C/Y=12;
PMT:END
D. N=;1% = 8.4; PV=-750; PMT=46.5; FV=0; P/Y=12; C/Y=12;
To calculate the number of payments for Kendra's loan using a TVM Solver, the correct setup includes an APR of 8.4% converted to a monthly rate of 0.7%, with matching payment and compounding frequencies, making Option A the accurate choice.
Explanation:When Kendra takes out a loan to buy a stereo, calculating the number of payments she will have to make involves understanding the terms used in Time Value of Money (TVM) calculations. The correct set of values must account for the annual percentage rate (APR) being compounded monthly, which requires converting the APR to a monthly rate, and ensuring the payment and compounding periods match.
For Kendra's loan:
APR is 8.4%, implying a monthly interest rate (I%) of 0.7% (8.4% divided by 12).The present value (PV) of the loan is -$750, indicating an outflow of cash.Her monthly payment (PMT) is $46.50, aimed at reducing the loan balance.The future value (FV) she aims for is $0, meaning she intends to fully repay the loan.P/Y (Payments per year) and C/Y (Compounding periods per year) both should match the monthly nature of the loan, hence should be 12.Given these conditions, the only option that correctly configures all elements for a TVM Solver is Option A:
N=; I% = 0.7; PV=-750; PMT=46.5; FV=0; P/Y=12; C/Y=12; PMT:END
This configuration accurately reflects the loan's terms, allowing the calculation of the number of payments (N) Kendra will need to make.
The correct answer is: D. N=; 1% =8.4; PV=-750; PMT=46.5; FV=0; P/Y=12; C/Y=12; PMT:END. Option A uses annual percentage rate (APR), while option D uses the periodic interest rate (monthly rate). Given that the interest rate is compounded monthly, it's more appropriate to use the periodic interest rate (option D).
To calculate the number of payments Kendra will have to make to pay off the loan, we can use the Time Value of Money (TVM) Solver feature of a graphing calculator. We need to set up the values correctly to solve for the number of payments (N).
Let's go through the options:
A. N=; 1% =8.4; PV=-750; PMT=46.5; FV=0; P/Y=1; C/Y=12; PMT:END
B. N=; I% =0.7; PV=-750; PMT=46.5; FV=0; P/Y=12; C/Y=12; PMT:END
C. N=; 1% =0.7; PV=-750; PMT=46.5; FV=0; P/Y=1; C/Y=12; PMT:END
D. N=; 1% =8.4; PV=-750; PMT=46.5; FV=0; P/Y=12; C/Y=12; PMT:END
Let's analyze each option:
A. This option has the correct annual interest rate (8.4%), correct present value (loan amount), correct payment amount, and correct compounding periods per year. Hence, it's a potential correct option.
B. This option has the interest rate incorrectly set as 0.7%. It should be 8.4%, not 0.7%. Hence, it's incorrect.
C. Similar to option B, this option has the interest rate incorrectly set as 0.7%. Hence, it's incorrect.
D. This option has the correct interest rate (8.4%), correct present value, correct payment amount, and correct compounding periods per year. Hence, it's a potential correct option.
So, options A and D are potential correct options. Both have the correct interest rate and payment amount. The difference lies in how the interest rate is represented: option A uses annual percentage rate (APR), while option D uses the periodic interest rate (monthly rate).
Given that the interest rate is compounded monthly, it's more appropriate to use the periodic interest rate (option D). Therefore, option D is the most suitable choice.

Step-by-step explanation:
A single sheet of 20-pound bond paper is about a tenth of a millimeter thick. Each time you fold an ordinary sheet of paper in half, you double the thickness. What would be the thickness in kilometers if you were physically able to fold it 50 times? Note: For comparison, the distance from Earth to the Sun is about 149,600,000 kilometers. (Round your answer to the nearest kilometer.)
The paper would be 112589991 km thick if folded 50 times.
Step-by-step explanation:
Step 1; The sheet is [tex]\frac{1}{10}[/tex]mm thick which equals 0.1 mm. Every time it is folded it doubles in thickness. So if folded once it becomes 0.2 mm thick, if folded thrice it becomes 0.4mm thick.
Thickness if folded once = [tex]2^{1}[/tex] × 0.1 mm
thickness if folded twice = [tex]2^{2}[/tex]× 0.1 mm
Thickness if folded thrice = [tex]2^{3}[/tex] × 0.1 mm.
So if the paper is folded nth fold it would be [tex]2^{n}[/tex] × 0.1 mm thick.
Step 2; Using the above formula, if the paper is folded 50 times the thickness would be equal to [tex]2^{50}[/tex] × 0.1 mm = 112,589,990,684,262.4 mm.
1 km is equivalent to [tex]10^{6}[/tex]mm so 112,589,990,684,262.4 mm = 112,589,990.6842624 km which is rounded off to 112589991 km.
First: State the degree and tell which monomial (term) you determined to be the one as the greatest degree. Second: Classify each of the 2 polynomials. If it is NOT a polynomial, explain why you think it is not a polynomial. For example you may say: Polynomial # 4. has degree of 5 and is classified as a quintic polynomial of 4 terms. We covered this in class (see below). Explain in sentences how you determined degree and "name" or why it is NOT a polynomial. 1. 7x^4 + 5x^2 + x − 9 2. 7x^6 − 4x^3 + 1/x
Answer:
As the degree of the polynomial is said to be the highest degree of any of the terms. Therefore, the degree of [tex]7x^4\:+\:5x^2\:+\:x\:-\:9[/tex] is 4The expression [tex]7x^6\:-\:4x^3\:+\:1/x[/tex] is not a polynomial as the term [tex]\frac{1}{x}[/tex] is not a polynomial as the the variable [tex]x[/tex] is in the denominator.Step-by-step explanation:
Considering the given expressions
[tex]7x^4\:+\:5x^2\:+\:x\:-\:9[/tex][tex]7x^6\:-\:4x^3\:+\:1/x[/tex]As we know that
A polynomial is considered to be the sum of monomials where each monomial is said to be a term.The degree of a polynomial is the considered to be the greatest degree of its terms.A polynomial is normally written with the term with the highest exponent of the variable first and afterwards decreasing from left to right.The first term of a polynomial is said to be the leading coefficient.The degree of the polynomial is said to be the highest degree of any of the terms.Now, considering the expression
[tex]7x^4\:+\:5x^2\:+\:x\:-\:9[/tex]Here, the first term (monomial) i.e. [tex]7x^4\:[/tex] has the highest exponent of the variable. Here, the highest exponent is 4.
As the degree of the polynomial is said to be the highest degree of any of the terms.
Therefore, the degree of [tex]7x^4\:+\:5x^2\:+\:x\:-\:9[/tex] is 4.
The polynomial [tex]7x^4\:+\:5x^2\:+\:x\:-\:9[/tex] can also be called a quadrinomial as it has four terms.
Also considering the second expression
[tex]7x^6\:-\:4x^3\:+\:1/x[/tex]This expression is not a polynomial.
For an expression to be a polynomial, it must must have to carry
no square roots of variables. For example, [tex]\sqrt{y}[/tex] is not a polynomial as the variable y is inside a radical. no fractional or negative powers on the variables, For example, [tex]5x^{-3}[/tex] is not a polynomial as the x variable has a negative exponent.and no variables in the denominators of any fractions. For example, [tex]\frac{1}{x}[/tex] is not a polynomial as the the variable x is in the denominator.Therefore, the expression [tex]7x^6\:-\:4x^3\:+\:1/x[/tex] is not a polynomial as the term [tex]\frac{1}{x}[/tex] is not a polynomial as the the variable x is in the denominator.

Is -38,-68,-98,-128,... arithmetic
Answer:
yes
Step-by-step explanation
the common difference is -30
Final answer:
The sequence -38, -68, -98, -128,... is an arithmetic sequence because the common difference between consecutive terms is consistent, which is -30.
Explanation:
The student has asked whether the sequence -38, -68, -98, -128,... is arithmetic. To determine if a sequence is arithmetic, we need to check if the difference between any two consecutive terms (also known as the common difference) is the same.
Let's calculate the difference between the first two terms:
-68 - (-38) = -68 + 38 = -30
Now, let's calculate the difference between the second and the third terms:
-98 - (-68) = -98 + 68 = -30
Similarly, the difference between the third and the fourth terms is:
-128 - (-98) = -128 + 98 = -30
Since the common difference is the same (-30) for all consecutive terms mentioned, the sequence is indeed an arithmetic sequence.
David is making a wall out of bricks. Each brick is 2/3 foot long. There are 20 bricks lined up end to end to make the wall. What is the total length of the wall in inches?
The total length of wall is 160 inches
Solution:
Given that,
[tex]Length\ of\ each\ brick = \frac{2}{3}\ foot[/tex]
1 feet = 12 inches
Therefore,
[tex]Length\ of\ each\ brick = \frac{2}{3} \times 12\ inches = 8\ inches[/tex]
There are 20 bricks lined up end to end to make the wall
To find: Total length of wall in inches
[tex]Total\ length\ of\ wall = \text{length of each brick } \times \text{ total number of bricks}[/tex]
Thus we get,
[tex]Total\ length\ of\ wall = 8 \times 20\\\\Total\ length\ of\ wall = 160\ inches[/tex]
Thus total length of wall is 160 inches

MN = 10
Step-by-step explanation:
To find the length of a line segment or the straight distance between two points, use the formula [tex]L = \sqrt{(x_{2}-x_{1})^{2}+(y_{2}-y_{1})^{2}}[/tex] , where you can substitute two points, which would be (x₁ , y₁) and (x₂ , y₂). "L" stands for length.
Choose point 1 and point 2:
Point 1: M (2, -3) x₁ = 2 y₁ = -3
Point 2: N (8, 5) x₂ = 8 y₂ = 5
Substitute the values for the variables:
[tex]L = \sqrt{(x_{2}-x_{1})^{2}+(y_{2}-y_{1})^{2}}[/tex]
[tex]L = \sqrt{(8-2)^{2}+(5-(-3))^{2}}[/tex] Solve inside each bracket first by adding
[tex]MN = \sqrt{(6)^{2}+(8)^{2}}[/tex] Square each number
[tex]MN = \sqrt{36+64}[/tex] Add the numbers
[tex]MN = \sqrt{100}[/tex] Find the square root
[tex]MN = 10[/tex] Length of the line segment
Therefore the length of the line segment MN is 10.
