Michelle has four credit cards with the balances and interest rates listed below. She would like to consolidate all of her credit cards masingle credit card with an interest rate of 16% and pay off the balance in 36 months. If she did so, what would Michelle's monthly credit card payment be? Credit Card APR $4380 $1,385 a. $36735 b $464.95 $685.23
Answer:
$194.0008
Step-by-step explanation:
I'm not sure if this is correct but I hope it helps
16% of 4380
0,16×4380
=$700.8
16% of 1385
0,16×221.6
=221.6
16% of 36735
0,16×36735
=$5877.6
16% of 464.95
0,16×464.95
=$74.392
16% of 685.23
0,16×685.23
=$109. 6368
700.8+221.6+3877.6+5877.6+74.392+109.6368=$6984.0288
6984.0288÷36=$194.0008
the monthly payment for Michelle's consolidated credit card balance would be approximately $201.59.
What is an expression?Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.
Now, the total balance of all four credit cards:
Total balance = $4380 + $1385
Total balance = $5765
Hence, Determine the interest rate for the consolidated credit card: Interest rate = 16%
And, the term of the loan:
Term = 36 months
Hence, Use a loan calculator to calculate the monthly payment, using the total balance, interest rate, and term:
Monthly payment = $201.59
So, the monthly payment for Michelle's consolidated credit card balance would be approximately $201.59.

Help please thank you
Answer:
A, B and D are true.
Step-by-step explanation:
g (x) = x² - 4x + 3
f (x) = x² - 4x
What this means is that;
g (x) = f (x) + 3
What this implies is that the graph of g (x) is equivalent to when we shift that of f function graph up by 3 units.
Since g (x) is essentially shifting of f (x) upwards by 3 units, it means the graphs will never intersect.
It also implies that the vertex of g (x) will be above that of f (x)
Also since it only moves up and not in any other direction, both functions will still have the same line of symmetry.
Thus, options A, B and D are correct

a) Ronu's present age
b) Ronu's age after 2 years
c) Shaani's present age
d) Shaani's age after 2 years
What hould be added to 100 to get - 132
Answer:
x = -232
Step-by-step explanation:
Ronu's present age is "x “years and her sister Shaani's present age is twice of Ronu's age.
(a) Ronu's present age = x years
(b) Ronu's age after 2 years = (x+2) years
(c) Shaani's present age = 2x years
(d) Shaani's age after 2 years = (2x+2) years
Let x should be added to 100 to get -132.
x+100 = -132
x = -100-132
x = -232
Hence, -232 must be added to 100 to get -132.

A researcher wants to estimate the percentage of all adults that have used the Internet to seek pre-purchase information in the past 30 days, with a tolerable sampling error (E) of 0.03 and a confidence level of 95%. If prior secondary data indicated that 25% of all adults had used the Internet for such a purpose, what is the required sample size for the new study
Answer:
The required sample size for the new study is 801.
Step-by-step explanation:
In a sample with a number n of people surveyed with a probability of a success of [tex]\pi[/tex], and a confidence level of [tex]1-\alpha[/tex], we have the following confidence interval of proportions.
[tex]\pi \pm z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]
In which
z is the zscore that has a pvalue of [tex]1 - \frac{\alpha}{2}[/tex].
The margin of error is:
[tex]M = z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]
25% of all adults had used the Internet for such a purpose
This means that [tex]\pi = 0.25[/tex]
95% confidence level
So [tex]\alpha = 0.05[/tex], z is the value of Z that has a pvalue of [tex]1 - \frac{0.05}{2} = 0.975[/tex], so [tex]Z = 1.96[/tex].
What is the required sample size for the new study?
This is n for which M = 0.03. So
[tex]M = z\sqrt{\frac{\pi(1-\pi)}{n}}[/tex]
[tex]0.03 = 1.96\sqrt{\frac{0.25*0.75)}{n}}[/tex]
[tex]0.03\sqrt{n} = 1.96\sqrt{0.25*0.75}[/tex]
[tex]\sqrt{n} = \frac{1.96\sqrt{0.25*0.75}}{0.03}[/tex]
[tex](\sqrt{n})^2 = (\frac{1.96\sqrt{0.25*0.75}}{0.03})^2[/tex]
[tex]n = 800.3[/tex]
Rounding up:
The required sample size for the new study is 801.

Answer:

Step-by-step explanation:
The width of a rectangular table is 2.3 feet less than its length. If the area of the table is 9.5 square feet, find its dimensions.
Answer: Width = 12 feet
length = 9 feet
The dimensions of the rectangular table are approximately 5.77 feet by 3.47 feet.
Let's denote the length of the rectangular table as L.
According to the given information, the width is 2.3 feet less than the length. Therefore, the width can be expressed as L - 2.3.
The area of a rectangle is calculated by multiplying its length by its width. In this case, the area is given as 9.5 square feet.
So, we have the equation:
Length * Width = Area
L * (L - 2.3) = 9.5
Expanding the equation:
L² - 2.3L = 9.5
Rearranging the equation:
L² - 2.3L - 9.5 = 0
To solve this quadratic equation, we can use the quadratic formula:
L = (-b ± √(b² - 4ac)) / (2a)
For this equation, a = 1, b = -2.3, and c = -9.5.
Substituting the values into the quadratic formula, we get:
L = (-(-2.3) ± √((-2.3)² - 4 * 1 * (-9.5))) / (2 * 1)
L = (2.3 ± √(5.29 + 38)) / 2
L = (2.3 ± √43.29) / 2
Calculating the square root and simplifying further, we find two possible values for L:
L ≈ 5.77 or L ≈ -3.07
Since length cannot be negative, we discard the negative solution.
Therefore, the length of the rectangular table is approximately 5.77 feet.
To find the width, we substitute this value back into the equation for the width:
Width = Length - 2.3
Width ≈ 5.77 - 2.3
Width ≈ 3.47 feet
So, the dimensions of the rectangular table are approximately 5.77 feet by 3.47 feet.

What is the measure of the angle of the hands on a clock if it is 3:24?
Answer:
from 3 o’clock until 3:20, the minute hand will move 1/3 of the way around the circle or 120 degrees. But the hour hand has also moved 1/3 of the way to the next number, or 10 degrees.
Answer:
42deg
Step-by-step explanation:
Let's see.
We'll consider 12:00 the "starting position"
The minute hand moves with the speed of 360deg in an hour, so 6deg per minute.
The hour hand moves with the speed of 360deg in 12hours, so 30deg per hour, so 0.5deg per minute.
at 3:24, the minute hand has moved 24*6deg=144deg from the starting position, while the hour hand has moved by 3*30deg + 24*0.5deg = 102deg
The absolute difference of the angles is 144deg-102deg = 42deg and it's the angle between the hands.

Step-by-step explanation:
<1=58° (180-90-32)
<3=32° (Same a the angle across from it because it’s an isosceles triangle)

This Rhomus is definitely not drawn correctly, so the image is deceptive. For example, two 32° angles would not make an obtuse angle. You just have to ignore the picture and do the Math.

Find the radius of a circle with a circumference of 23.55 feet. Use 3.14 for
Answer:
3.75
Step-by-step explanation:
The radius of the circle will be (11.775/π).
What is the area of a circle? What is an exponential function? Differentiate between equation and expression? area of circle : The area of a circle is equivalent to -[A] = πr² = πd²/4
function : In mathematics, a function from a set X to a set Y assigns to each element of X exactly one element of Y. The set X is called the domain of the function and the set Y is called the codomain of the function.expression : A mathematical expression is made up of terms (constants and variables) separated by mathematical operators.equation : A mathematical equation is used to equate two expressions.Given is the circumferance of the circle is 23.55 feet.
We can write -
2πr = 23.55
r = (23.55/2π)
So, the area of the circle will be -
{A} = πr²
{A} = π x (23.55 x 23.55)/4π²
{A} = (555/4π)
{A} = 138.75/π
r = (23.55/2π)
r = (11.775/π)
Therefore, the radius of the circle will be (11.775/π).
