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]
Therefore, the amount of money that Carter would have in his account when Savannah's money has doubled in value is $123,543 (nearest dollar).

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.

What is an isosceles triangle?An isosceles triangle is a type of triangle that has any two sides equal in length. 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°
In conclusion the value of x in the first and second diagrams are 76° and 80° respectively

The height of a rectangular box is one inch and 56.23 inch cubed respectively. What is the volume of the box if the if the height is increased to 13 inches?
Therefore, the new volume comes out to be 787.22 cm3.
What category of science is volume?The volume of a substance is a measurement of how much space it occupies. Matter is a term used to describe a physical substance that has mass and occupies space. In physical disciplines like chemistry, cubic meters are the standard unit of volume (m3). This yields other units like the litre (L) and milliliter (mL) (mL).
Here,
When the height was raised here by 13 inches, it was equivalent to adding an additional 13 levels, each measuring 56.23 cm3, to the prism that already existed.
Your new volume would therefore be: => 56.23 cm3 + 13 (56.23 cm3) = > 787.22 cm3.
therefore, the new volume comes out to be 787.22 cm3.

The second one includes 1 small tier and 5 medium tiers, which is enough servings for 247 guests. How many guests does each size of tier serve.. ?
Answer:
Step-by-step explanation:
3 small tiers + 5 medium tiers= 291 guests
1 small tier+5 medium tiers=247 guests
The 2 cakes have the same medium tiers(5 medium tiers). If we subtract 291-247 we will have the number of guest that 2 small tiers serve.
291-247= 44 guests serve per 2 small tiers
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.
Lauren was given a gift card for a coffee shop. Each morning, Lauren uses the card to buy one cup of coffee. The original amount of money on the gift card was $10 each cup of coffee costs $2. Make a table of values and then write an equation in terms of x, representing the amount money remaining on the card after buying x cups of coffee.
The amount of money left on the gift card, in term of the number of cups, a Lauren has bought is represented by the equation would be A = 10 - 2a.
What is an equation?
An equation is an expression that shows the relationship between two or more numbers and variables.
We are given that from the task content that the total amount of money Lauren has initially is $10.
Hence, each cup of coffee costs $2.
Since the amount of money Lauren has left each time,
That is related to the number of coffee cups bought by the equation;
A = 10 -2a.
where a ranges be between 0 and 5.

The correct statements for the triangle are given as follows:
The median BE is parallel to y-axis.The length of the median AD is 15 units.The centroid of the triangle is the point (8, 6).How to obtain the correct statements?The vertices of the triangle are given as follows:
A(0,0), B(8,12), C(16,6).
The midpoints of each side are given by the mean of the coordinates at the extrema of these sides, hence:
D: (12,9).E: (8,3).F: (4,6).The segment BE is a vertical segment, as the x-coordinate is fixed at x = 8, hence ti is parallel to the y-axis.
Given two points, the slope is given by the change in y divided by the change in x. Then the slope of CF is given as follows:
m = (6 - 6)/(16 - 4) = 0.
The length of the segment AD is given as follows:
Length of AD = square root(12² + 9²) = 15 units.

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
