eight students got a B on the final test. Ig the ratio of the number of students who got an A to the number of students who got a B is y: x, how many students got an A? Write a formula that gives the number of students who get an A given x and y.

Answers

Answer 1

The ratio of students that got A to students that got B is an illustration of comparison

The number of students that got A in the test is 8y/x

How to determine the number of students

The ratio of the student is given as:

A : B = y : x

8 students got B in their final test.

So, the ratio becomes

A : 8 = y : x

Express the ratio as a fraction

[tex]\frac A8 = \frac yx[/tex]

Multiply both sides by 8

[tex]A = \frac{8y}x[/tex]

Hence, the number of students that got A in the test is 8y/x

Faith is taking an $8,100, 2 ½ -year loan with an APR of 8. 22%. What is the monthly payment for this loan?

Answers

Using simple interest, it is found that the monthly payment for this loan is of $325.485.

Simple Interest

Simple interest is used when there is a single compounding per time period.

The amount of money after t years in is modeled by:

[tex]A(t) = A(0)(1 + rt)[/tex]

In which:

A(0) is the initial amount.r is the interest rate, as a decimal.

In this problem, the parameters are A(0) = 8100, r = 0.0822, t = 2.5, hence, the total amount is:

[tex]A(t) = A(0)(1 + rt)[/tex]

[tex]A(t) = 8100[1 + 0.0822(2.5)][/tex]

[tex]A(t) = 9764.55[/tex]

it will be paid over 2.5 x 12 = 30 months, hence the monthly payment is given by:

M = 9764.55/30 = $325.485.

Answers

The function A(n) = 22(1.1)^n-1 is an illustration of a geometric series

The sum of the 23rd through 40th terms of the series is 17.49

How to determine the sum of the series

The nth term of the geometric series is given as:

[tex]A(n) = 22(1.1)^{n-1[/tex]

The nth term of a series is represented as:

[tex]A(n) = ar^{n-1[/tex]

So, by comparison;

We have:

[tex]a = 22[/tex]

[tex]r = 1.1[/tex]

The sum of nth term of a geometric progression is:

[tex]S_n = \frac{a(r^n - 1)}{r - 1}[/tex]

Start by calculating the sum of the first 22 terms

[tex]S_{22} = \frac{22(1.1^{22} - 1)}{22 - 1}[/tex]

[tex]S_{22} = \frac{157.086}{21}[/tex]

[tex]S_{22} = 7.48[/tex]

Next, calculate the sum of the first 40 terms

[tex]S_{40} = \frac{22(1.1^{40} - 1)}{40 - 1}[/tex]

[tex]S_{40} = \frac{973.70}{39}[/tex]

[tex]S_{40} = 24.97[/tex]

Subtract S22 from S40

[tex]S_{40} - S_{22} = 24.97 - 7.48[/tex]

[tex]S_{40} - S_{22} = 17.49[/tex]

Hence, the sum of the 23rd through 40th terms of the series is 17.49

In order to subtract these fractions, we should turn the first fraction into an improper fraction.

What is an improper fraction?

An improper fraction is a fraction whose numerator is greater than its denominator.

How to turn a mixed number into an improper fraction?

Multiply the whole number by the denominator.

      - Multiply 1 times 8

    2. Add the numerator.

     - Add 7 to the product of 1 and 8 (which, of course, is equal to 8)

  8+7=15

Therefore, we have

[tex]\bold{\displaystyle\frac{15}{8} -\frac{3}{8}}[/tex]

Now all we have to do is subtract the numerators!

[tex]\bold{\displaystyle\frac{12}{8}}[/tex]

Surprise! This fraction can be reduced:

Answers

The interest that Niki paid in total will b A $39,695.48

what will be the interest paid by Nikki?

We will use the formula of amount for two monthly compounded

[tex]A=\dfrac{P(1-(1+\dfrac{r}{t}^{-nt} )}{\dfrac{r}{t} }[/tex]

P is the periodic payment.

Here, A = $61,60

r = 0.0984

t = 6

n = 11 years  

By putting values in the formula we get,

[tex]61600=\dfrac{P(1-(1+\dfrac{0.0984}{6} ^{-11\times6} )}{\dfrac{0.0984}{6} }[/tex]

[tex]61600=\dfrac{P(1-(1+0.0164)^{-66}}{0.0164}[/tex]

[tex]1010.24=P(1-0.341769)[/tex]

[tex]1010.24=0.658231\times P[/tex]

[tex]P=$1534.78[/tex]

So, Niki pays $1534.78 every two months for eleven years.

Now the total payment made by Niki = [tex]11\times 6\times 1534.78=101295.48[/tex]

Hence, interest paid is = [tex]101295.48-61600=39695.48[/tex]

Thus interest that Niki paid in total will b A $39,695.48

True or False The Solutions, Roots, X-intercepts and zeros of a quadratic equation are all the same thing? why

Answers

Yes, solutions, roots, x-intercepts, and zeros are the same thing.

What is a quadratic equation?

The general quadratic equation is given by:

a*x^2 + b*x + c = 0

So the solutions are the values of x such that the above thing is zero.

On another hand, a parabola or a quadratic function is given by:

a*x^2 + b*x + c = y

The roots, zeros, or x-intercepts (these represent the same thing) are given by:

a*x^2 + b*x + c = 0

Zero or Root means that when you evaluate the function in that value the outcome is zero.X-intercept means that for that value of x, the function intercepts the x-axis, so the function is equal to zero.

So these are the values of x such that the function becomes equal to zero, so these are exactly the same thing as the solutions of a quadratic equation.

Concluding, yes, solutions, roots, x-intercepts, and zeros are the same thing.
