Autumn invested $69,000 in an account paying an interest rate of 6 3/8% compounded continuously. Jayden invested $69,000 in an account paying an interest rate of 6 1/4% compounded quarterly. After 14 years, how much more money would Autumn have in her account than Jayden, to the nearest dollar?

Answers

Answer:

4,038.21

Step-by-step explanation:

I'm going to assume that when you write 6 3/8% that equals 51/8%=6.375%

To find the value in the first equation we have

69000*e^(.06375*14)=168,444.5313

The second equation is as follows

69000(1+(.0625/4))^(14*4)=164,406.3243

Subtract the two and get 4,038.2071

If the cost of 4 pears and 2 peaches equals $1.00 and the cost of 2 pears and 3 peaches equals $0.70 how much does each pear and each peach cost

Answers

Answer:

20 p per pear 10p per peach

Step-by-step explanation:

Hope this helps

Answer:

1 pear costs 20 cents. 1 peach costs 10 cents.

Step-by-step explanation:

x represents pears

y represents peaches

4x + 2y = 1

2x + 3y = 0.7

multiply the second equation by -2 to elimate the x variable

(2x +3y = 0.7) -2 = -4x - 6y = -1.4

add the new equation to the first original one:

4x + 2y = 1

-4x - 6y = -1.4

-4y = -0.4. divide both sides by -4, y = 0.10

plug in y = 10, solve algebraically and get x = 0.20

Lastly, check your work:

4(0.20) + 2(0.10) = 1

2(0.20) + 3(0.10) = 0.7

Deana made a scale drawing of her patio using a scale of 1/2 cm =1 foot what is the actual width, in feet, of deanas patio

Answers

Full question attached

Answer and explanation:

Given that 1/2cm= 1 foot

5cm= 2×5=10 feet

Length is twice the width, therefore real length of shape = 10×2=20 feet

Perimeter is sum of all sides= 20 feet+20 feet+10 feet+10 feet = 60 feet

Therefore Deana's Patio= 60 feet in real length

3x-5/6=1/6 what does x=?

Answers

Answer:

x = 2

Step-by-step explanation:

[tex]\frac{3x-5}{6} = \frac{1}{6} \\[/tex]

In order to solve this, you must get the denominator off of the left-hand side of the equation, by multiplying 6 on each side, in order to get the denominators to cancel. This leaves you with:

[tex]3x-5 = 6/6\\3x-5 = 1[/tex]

Then, you add 5 to each side.

[tex]3x = 6[/tex]

Divide by 3, to get x by itself.

[tex]x = 2[/tex]

Which gets us to our final answer of x = 2.

Then, you can plug x back into the equation just to double-check yourself:

[tex]\frac{3(2)-5}{6} = \frac{1}{6} \\\\\frac{6-5}{6} = \frac{1}{6}\\\\\frac{1}{6} = \frac{1}{6}[/tex]

I hope that this helped you understand to concept a little better. Good luck.

A race car can travel at a speed of 3.4 x 10^2 miles/hour. The Speed of Sound is approximately 7.6 × 10^2 miles/hour. How many times faster is the Speed of Sound than the Bullet Train?

Answers

Answer:

The speed of sound is 2.23 times of the speed of race car

Step-by-step explanation:

Given that,

The speed of a race car = [tex]3.4\times 10^2\ mi/h[/tex]

The speed of sound = [tex]7.6\times 10^2\ mi/h[/tex]

Dividing the speed of sound to the speed of a race car. So,[tex]\dfrac{\text{speed of sound}}{\text{speed of race car}}=\dfrac{7.6\times 10^2}{3.4\times 10^2}\\\\\dfrac{\text{speed of sound}}{\text{speed of race car}}=2.23[/tex]

So, the speed of sound is 2.23 times of the speed of race car.

One page of a petition can hold p signatures. You were able to get 4p+5 people to sign the petition. Your friend was able to get 2p−3 people to sign the petition. Write an expression in simplest form that represents the number of people that you and your friend got to sign the petition.

Answers

Answer:

6p - 2

Step-by-step explanation:

The expression that needs to be made in this question refers to the total number of people that signed the petition. To calculate this we need to add the total number of signatures that both you and your friend were able to acquire. Once we do this we simply combine like terms in order to simplify the expression as much as possible.

4p + 5 + 2p - 3

4p + 2p + 5 - 3

6p - 2

Therefore, the total and simplified expression for the total number of signatures would be 6p - 2
