x=87

x=29

Answer:

43.2 years

Step-by-step explanation:

The formula for continuously compounded interest on a principal investment Pat a given interest rater

over time tin years is given by A = Pe^rt

P = Initial amount compounded = $12000

A = Amount compounded continuously after t years = six times it's original worth

= 6 × $12,000 = $72000

r = Interest rate = 4.15%

t = time in years = ?

Making t the subject of the formula

t = ln(A/P) / r

First, convert R percent to r a decimal

r = R/100

r = 4.15%/100

r = 0.0415 per year,

Then, solve our equation for t

t = ln(A/P) / r

t = ln(72,000.00/12,000.00) / 0.0415

t = 43.175 years

Approximately t = 43.2 years

The time required to get a total amount of $ 72,000.00 from compound interest on a principal of $ 12,000.00 at an interest rate of 4.15% per year and compounded continuously is 43.2years.

Hello!

Judy can buy [tex]\boxed{ \bf 5~sheets~of~felt}[/tex] and [tex]\boxed{ \bf 7~sheets~of~card~stock.}[/tex]

I solved the problem in the image attached below. Go check it out! If you don’t understand a certain step, you may ask me in the comments.

Answer:

The amount is $2137.24 and the interest is $237.24.

Step-by-step explanation:

STEP 1: To find amount we use formula:

A = P[tex](1+\frac{x}{y} )nt[/tex]

A = total amount P = principal or amount of money deposited, r = annual interest rate n

= number of times compounded per year t = time in years In this example we have

P = $1900 , r = 4% , n = 1 and t = 3 years

After plugging the given information we have

A = 1900 [tex](1+\frac{0.04}{1})^{1*3}[/tex]

A = 1900 · 1.0[tex]4^{3}[/tex]

A = 1900 · 1.124864

A = 2137.24

STEP 2: To find interest we use formula A = P + I, since A = $2137.24 and P = $1900 we

have:

A = P + I

2137.24 = 1900 + I

I = 2137.24 − 1900

I = 237.24

Answer:

$1954

Step-by-step explanation:

Given the profit function expressed as;

y=-3x^2 + 197x – 1279

The profit is at maximum when dy/dx = 0

dy/dx = -6x + 197

0 = -6x+197

6x = 197

x = 197/6

x = 32.83

substitute 32.83 into the modeled function

y=-3x^2 + 197x – 1279

y -3(32.83)²+197(32.83) - 1279

y = -3(1,078.03)+6,467.51 - 1279

y = -3,234.09+6,467.51-1279

y = 1,954.42

hence the maximum amount of profit the company can make, to the nearest dollar is $1954

Answer:

Width=9.5, Length=32.5

Step-by-step explanation:

Let x be the width of the rectangle,

The length is 4 feet more than 3 times the width,

The length= 3x+4

The perimeter is

2(x)+2(3x+4)=84

2x+6x+8=84

8x=76

x=76/8

x=9.5

The Width=9.5

Length= 3(9.5)+4=32.5

Answer:

The equation would be 8n + 11 = 3n + 26.

Answer:

I'm gonna assume we're talking about  "n".

b) 8n+11=3n+26 (because they are corresponding angles)

n=3

Step-by-step explanation:

8n+11=3n+26    

simplifying:

8n-3n+11-11=3n-3n+26-11

5n=15

n=3

Square Root of 72 in Simplest Radical Form

Simplest Radical Form

Here we answer "What is the square root of 72 (√72) in simplest radical form?" The square root of 72 in its simplest form means to get the number 72 inside the radical √ as low as possible.

Here is how to do that! First we write the square root of 72 like this:

√72

The largest perfect square of the factors of 72 is 36. We can therefore convert √72 like this:

√36 × 2

Next, we separate the numbers inside the √ as such:

√36 × √2

√36 is a perfect square that equals 6. We can therefore put 6 outside the radical and get the final answer to square root of 72 in simplest radical form as follows:

6√2

Answer:

31136

Step-by-step explanation:

To find the how much an number increased by a percent. Divide the percent by 100. 23/100=0.23.

Then multiply 0.23 by the original number which is 25,314. Which gives us about 5822.

Then since it INCREASED, we are going to add that number it increased to the original. 25314+5822= 31136.

Answer:

Good Luck, hope it helps:)

Step-by-step explanation:

23% of 25,314 = 25,314 x .23 = 5822 then add that to the original population. 25,314 + 5,822 = 31,136

Answer:

30.89cm³

Step-by-step explanation:

Given that:

Side length, s of square = 12cm

Area of square = s² = 12² = 144cm²

Since the circle touches the edge of tbe square, then the diameter of the circle = side length of square = 12 cm

Area of a circle = πr²

Radius, r = diameter / 2 = 12/2 = 6cm

A = 3.142 * 6^2

A = 3.142 * 36

A = 113.112 cm²

Area of shaded portion = area of square - area of circle

= 144cm² - 113.112cm³

= 30.89cm³
