Using the interest rates formula, we know that an automobile that costs $24588.44 is within our means.
What are interest rates?The amount of interest due each period expressed as a percentage of the amount lent, deposited, or borrowed is known as an interest rate.
The total interest on a loaned or borrowed sum is determined by the principal amount, the interest rate, the frequency of compounding, and the period of time the loan, deposit, or borrowing took place.
So, let's say the car's affordable price is P:
The entire payback is equal to P r/100 T + P.
In this case, P, r = 4.75, and T = 9 years.
$351,00 = P × (4.75/100 × 9 + 1)
$351,00 = P × ( 0.4275 + 1)
$351,00 = P × 1.4275
P = 351,00 / 1.4275
When you use the division operation, we receive:
P = $24588.44
Therefore, using the interest rates formula, we know that an automobile that costs $24588.44 is within our means.

Carter invested $70,000 in an account paying an interest rate of 1.125% compounded continuously. Savannah invested $70,000 in an account paying an interest rate of 1.375% compounded quarterly. To the nearest dollar, how much money would Carter have in his account when Savannah's money has doubled in value?
Step 1: Figure out when Savannah will double her account value:
We need to solve [tex]140000 = 70000\left(1+\frac{0.01375}{4}\right)^{4t}[/tex].
Divide by 70000:
[tex]2 = \left(1+\frac{0.01375}{4}\right)^{4t}[/tex]
Take the natural log of both sides and bring the exponent down:
[tex]\ln(2) = 4t\cdot\ln\left(1+\frac{0.01375}{4}\right)[/tex]
Divide by that mess multiplied by t:
[tex]\dfrac{\ln(2)}{4\ln\left(1+\frac{0.01375}{4}\right)} = t[/tex]
Throw that into a calculator and you get about 50.497297884.
Depending on how picky your teacher is, we'd need to round this to the next time the interest is compounded, since it's only compounded each quarter, so t = 50.5. (The fact is that Savannah's account will never exactly double in value.)
Step 2:
Now, we need to evaluate Carter's continuously compounded investment for 50.5 years:
[tex]B = 70000e^{0.01125\cdot(50.5)}\approx123546.825994[/tex]
B ≈ 123547 to the nearest dollar.
As a comparison, here's the other calculation with the more precise t value.
[tex]B = 70000e^{0.01125\cdot(50.497297884)}\approx123543.070375[/tex]
B ≈ 123543 to the nearest dollar.
Again, I would say the 50.5 calculation is actually more correct, since Savannah's account only compounds the interest each quarter, but you'll have to decide what your teacher would say.
Answer:
$123,543 (nearest dollar)
Step-by-step explanation:
Find the length of time Savannah has to invest her money for it to double.
[tex]\boxed{\begin{minipage}{8.5 cm}\underline{Compound Interest Formula}\\\\$ A=P\left(1+\frac{r}{n}\right)^{nt}$\\\\where:\\\\ \phantom{ww}$\bullet$ $A =$ final amount \\ \phantom{ww}$\bullet$ $P =$ principal amount \\ \phantom{ww}$\bullet$ $r =$ interest rate (in decimal form) \\ \phantom{ww}$\bullet$ $n =$ number of times interest is applied per year \\ \phantom{ww}$\bullet$ $t =$ time (in years) \\ \end{minipage}}[/tex]
Given:
A = $140,000P = $70,000r = 1.375% = 0.01375n = 4 (quarterly)Substitute the given values into the formula and solve for t:
[tex]\implies 140000=70000\left(1+\dfrac{0.01375}{4}\right)^{4t}[/tex]
[tex]\implies 140000=70000\left(1.0034375\right)^{4t}[/tex]
[tex]\implies2=\left(1.0034375\right)^{4t}[/tex]
[tex]\implies \ln2=\ln\left(1.0034375\right)^{4t}[/tex]
[tex]\implies \ln2=4t\ln\left(1.0034375\right)[/tex]
[tex]\implies t=\dfrac{\ln 2}{4 \ln\left(1.0034375\right)}[/tex]
[tex]\implies t=50.49729788[/tex]
Therefore, it would take approximately 50.5 years for Savannah's principal investment to double.
[tex]\boxed{\begin{minipage}{8.5 cm}\underline{Continuous Compounding Formula}\\\\$ A=Pe^{rt}$\\\\where:\\\\ \phantom{ww}$\bullet$ $A =$ final amount \\ \phantom{ww}$\bullet$ $P =$ principal amount \\ \phantom{ww}$\bullet$ $e =$ Euler's number (constant) \\ \phantom{ww}$\bullet$ $r =$ annual interest rate (in decimal form) \\ \phantom{ww}$\bullet$ $t =$ time (in years) \\ \end{minipage}}[/tex]
Given:
P = $70,000r = 1.125% = 0.01125t = 50.49729788...Substitute the given values into the formula along with the found value of t and solve for A:
[tex]\implies A=70000e^{0.01125 \times 50.4972...}[/tex]
[tex]\implies A=123543.0704...[/tex]

A racetrack charges $85 for each seat in the lower section, $60 for each seat in the upper sections, and $35 for field tickets. There are three times the amount of seats in the upper section as compared to the lower section. The revenue from selling all 22,800 seats is $948,000. How many seats are in the upper section of the racetrack?
Based on a system of equations, the number of seats in the upper section of the racetrack is 3,600.
What is a system of equations?A system of equations or simultaneous equations is two or more equations concurrently or simultaneously solved.
There are four methods for solving simultaneous equations:
MatrixGraphicalEliminationSubstitution.The charge per lower-section seat = $85
The cost per upper-section seat = $60
The fee per field ticket = $35
Let the number of lower-section seats = x
Let the number of upper-section seats = 3x
Let the number of field tickets = y
Equation 1: x + 3x + y = 22,800 or 4x + y = 22,800
85x + 60(3x) + 35y = 948,000
Equation 2: 85x + 180x + 35y = 948,000
From equation 1, y = 22,800 - 4x ...Equation 3
Substitute Equation 3 in Equation 2 to eliminate y:
85x + 180x + 35(22,800 - 4x) = 948,000
85x + 180x + 798,000 - 140x = 948,000
125x = 948,000 - 798,000
125x = 150,000
x = 1,200
The number of seats for each racetrack section:
Lower section seats, x = 1,200
Upper section, 3x = 3,600 (1,200 x 3)
Field tickets, y = 22,800 - 4x
y = 22,800 - 4(1,200)
= 18,000
Check:
85x + 180x + 35y = 948,000
85(1,200) + 180(1,200) + 35(18,000) = 948,000
102,000 + 216,000 + 630,000 = 948,000
948,000 = 948,000
Total revenue:
Lower section seats = $102,000 (85 x 1,200)
Upper section seats = $216,000 (60 x 3 x 1,200)
Field tickets = $630,000 (35 x 18,000)
Total revenue = $948,000
Thus, based on simultaneous equations, we can conclude that there are 3,600 seats in the upper section.

The two angles of an isosceles triangle, opposite to equal sides, are equal in measure. In geometry, triangle is a three-sided polygon that is classified into three categories based on its sides, such as:
Scalene triangle (All three sides are unequal)
Isosceles triangle (Only two sides are equal)
Equilateral triangle (All three sides are equal)
Find attachment to understand the explanation
∠A = ∠C ( base angles of an isosceles triangle)
∠A = x and ∠C = 76
Therefore ∠X = 76°
For diagram 6
interior ∠A + exterior ∠A = 180°
but exterior ∠A = 110°
interior ∠A = 180 - 110
interior ∠A = 70°
∠A = ∠C( base angles of isosceles ΔBAC) which is 70°
∠A + ∠B + ∠c = 180
∠B = 180 - 70 - 70
∠B = 40°
but ∠CBA + ∠CBD = 90 because ∠B = 90° and ∠CBA = 40°
∠∠CBD = 90 - 40
∠CBD = 50°
But ∠∠CBD = ∠BDC( base angles of isosceles Δ)
so that
∠BCD + ∠CBD + ∠BDC = 180°( angles in a triangle)
x + 50 + 50 = 180
x = 180 - 100
x = 80°

44:2=22 guests serve per one small tier.
So if we subtrack the number of guest that one small tier one the cake that has only one small tier we will obtain the number of guests that the 5 medium tiers serve.
247-22=225 guests serve per 5 medium tiers
225:5= 45 guests per 1 mediem tier.
Answer:45 guests serve in a medium tier22 guests serve in a small tier.Sorry, because english isn't my mother tongue.
Find X
Round to the nearest tenth.
Answer:
83 degrees
Step-by-step explanation:
17^2 = 8^2 + 16^2 - 2 * 8 * 16 * cos (X)
289 = 64 + 256 - 16 * 16 * cos(X)
289 = 320 - 256 cos(X)
289-320 = -256 cos(X)
- 31 = -256 cos(X)
31 = 256 cos(X)
31/256 = 256/256 cos(X)
0.121094 = cos (X)
x = arccos 0.121094
x = 83.04475538
Graph the linear equation by plotting points. x +y = 1
On solving the provided question, we got to know that - the points (0,1) and (1,0) to be used to plot the graph .
What is a linear equation?An algebraic equation of the form y=mx+b (where m is the slope and b is the y-intercept) with one constant and only one first-order (linear) term is called a linear equation. The above is sometimes called a "linear equation in two variables" where x and y are variables.
To draw a straight line, just two points are needed.
Finding the points where the graph intersects is one approach.

Write an explicit formula for
35, 44, 53, ....
an,the nth term of the sequence
Answer:
[tex]a_n=9n+26[/tex]
Step-by-step explanation:
An explicit formula for a sequence allows you to find the nth term of the sequence.
To determine if the sequence is arithmetic or geometric, calculate the differences between the terms:
[tex]35 \underset{+9}{\longrightarrow} 44 \underset{+9}{\longrightarrow} 53[/tex]
As the first differences are the same, the sequence is arithmetic with a common difference, d, of 9.
[tex]\boxed{\begin{minipage}{8 cm}\underline{General form of an arithmetic sequence}\\\\$a_n=a+(n-1)d$\\\\where:\\\phantom{ww}$\bullet$ $a_n$ is the nth term. \\ \phantom{ww}$\bullet$ $a$ is the first term.\\\phantom{ww}$\bullet$ $d$ is the common difference between terms.\\\phantom{ww}$\bullet$ $n$ is the position of the term.\\\end{minipage}}[/tex]
Substitute a = 35 and d = 9 into the formula to create an explicit formula for the nth term of the sequence:
[tex]\implies a_n=35+(n-1)9[/tex]
[tex]\implies a_n=35+9n-9[/tex]
[tex]\implies a_n=9n+26[/tex]
