$9,800.00 is invested at an annual rate of 11.6%, compounded continuously. How long will it take for that investment to grow to a value of 149,000.00? Round your answer (in years) to two decimal places at the END of your calculations.
Answers
Step-by-step explanation:
First, convert R as a percent to r as a decimal
r = R/100
r = 3.875/100
r = 0.03875 rate per year,
Then solve the equation for A
A = P(1 + r/n)nt
A = 10,000.00(1 + 0.03875/12)(12)(7.5)
A = 10,000.00(1 + 0.003229167)(90)
A = $13,366.37
Summary:
The total amount accrued, principal plus interest, with compound interest on a principal of $10,000.00 at a rate of 3.875% per year compounded 12 times per year over 7.5 years is $13,366.37.

square DEFG is inscribed in equilateral triangle ABC with a side length of 3+2√3.
Find: area of the square
Answers
Answer:
9 units²
Step-by-step explanation:
**Refer to the attached diagram**
The angles in the right triangle FAD (and HBE) are 30-60-90 which means that its sides will be in the ratio 1 : √3 : 2
Let x = the smallest side
Therefore, the sides of the right triangle FAD are in the ratio x : √3x : 2x
This means that:
the side length of the square = √3xthe side length of the triangle = x + √3x + x = (2 + √3)xWe are told that the side length of the triangle is 3 + 2√3, so:
[tex]\implies 3 + 2\sqrt{3} =(2 + \sqrt{3} )x[/tex]
[tex]\implies x=\dfrac{3 + 2\sqrt{3}}{2 + \sqrt{3} }[/tex]
[tex]\implies x=\sqrt{3}[/tex]
As the side length of the square is √3x, and x = √3,
⇒ side length of the square = √3 x √3 = 3
Now we know the side length of the square, we can calculate the area:
⇒ area of a square = side length x side length = 3 x 3 = 9 units²
An acre of land has an area of exactly 43,560 square feet. Which of the following is a reasonable estimate for the area of an acre of land?
A.
4 × 10-4 sq ft
B.
4 × 103 sq ft
C.
4 × 10-3 sq ft
D.
4 × 104 sq ft
Answers
Because an acre is 10 times the size of a football pitch and is often used area as a unit of measurement for broad regions, answer option (D) is a plausible estimate.
What is area?The size of a surface area can be expressed as an area. The surface area is the area of an open surface or the boundary of a three-dimensional object, whereas the area of a planar region or planar region refers to the area of a shape or flat layer. The area of an object is the entire amount of space occupied by a planar (2-D) surface or shape. Make a square with a pencil on a piece of paper. A two-dimensional character. On paper, the area of a shape is the amount of space it takes up. Assume the square is made up of smaller unit squares.
(D) 4 104 sq ft is the right answer.
Considering that an acre of land has an area of exactly 43,560 square feet, answer selections (A) and (C) are both too tiny, as they are both less than 1% of the size of an acre. Answer option (B) is 100 times the size of an acre and hence far too huge.
Because an acre is 10 times the size of a football pitch and is often used as a unit of measurement for broad regions, answer option (D) is a plausible estimate.

The stadium has two tiers of spectator seats and VIP seats. The number of VIP seats is 1/12 of all seats. The ratio of the number of 1st tier seats to the number of 2nd tier seats is 7:5. If there are 600 VIP seats, how many 1st tier seats are in the stadium?
Answers
Answer:
350
Step-by-step explanation:
350 because there are 1/12 of VIP seats and there are 600 so 600 times 1/12 is 6,600.
Then you minus off the 600 VIP seats so you get 6000
next you do 600 divided bu 12 because of the 1st tier seats and 2nd tier seats combined which then you get 50
lastly you do 50 times 7 because of the ration 7:5 1st tier seats to 2nd tier seats so then you get 350

Solve the following variation problem
The interest on an investment varies directly as the rate of interest.
If the interest is $49 when the interest rate is
4%, find the interest when the rate is
7.7%
Answers
Answer:
$94.325
Step-by-step explanation:
Given interest (I) varies directly as rate of interest (R) then the equation relating them is
I = kR ← k is the constant of variation
To find k use the condition I = 49 when R = 4 , then
49 = 4k ( divide both sides by 4 )
12.25 = k
I = 12.25R ← equation of variation
When R = 7.7 , then
I = 12.25 × 7.7 = $94.325

Calculate each unit rate.
a) A bus traveled 288 km in 4 hours.
b) A fish swam 75 m is 25 s.
c) Seven lemons cost $1.40.
d) $250 for a 5-day car rental.
Answers
Answers:
a) 72 km per hourb) 3 meters per secondc) 0.20 dollars or 20 cents per lemond) 50 dollars per day====================================
Explanation:
a) Divide the distance over time to get the unit rate, which is the speed in this case. Speed = distance/time = 288/4 = 72 km per hour. b) Like before, divide the distance over time to get 75/25 = 3 meters per second.c) We want the cost of 1 lemon. So we'll divide the total cost over 7 to get (1.40)/7 = 0.20 dollars = 20 cents per lemond) Divide the total cost over the 5 day period. This will get the cost of each day. So we have a unit cost of 250/5 = 50 dollars per day.Suppose that your data shows that Saturn orbits every 29.5 years. To the nearest hundredth of an au, how far is Saturn from the Sun?

What is inequality?Inequality is defined as an equation that does not contain an equal sign. Inequality is a term that describes a statement's relative size and can be used to compare these two claims.
Renaldo has a budget of $500 to buy gift boxes for a party. Large boxes cost $65 and small boxes cost $35.
Let 'x' be the number of small boxes and 'y' be the number of large boxes. Then the inequality is written as,
35x + 65y ≤ 500
If Renaldo buys 5 small gift boxes. Then the number of large gift boxes will be given as,
35 × 5 + 65y ≤ 500
175 + 65y ≤ 500
65y ≤ 325
y ≤ 5
The inequality is 35 × 5 + 65y ≤ 500. Then the number of large gift boxes will be 5.
