Jack invested $7,600 in an account paying an interest rate of 6\tfrac{1}{4}6 4 1 % compounded continuously. John invested $7,600 in an account paying an interest rate of 6\tfrac{3}{4}6 4 3 % compounded quarterly. After 19 years, how much more money would John have in his account than Jack, to the nearest dollar?
Answer: John would have $1371.33 more in his account than Jack.
Step-by-step explanation:
Formula to calculate amount after t years if compounded continuously:
[tex]A=Pe^{rt}[/tex]
Formula to calculate amount after t years if compounded quarterly:
[tex]A=P(1+\dfrac{r}{4})^{4t}[/tex]
, where P= Principal amount, r= rate of interest.
Given: P= $7,600
t=19 years
For Jack, [tex]r=6\dfrac{1}{4}\%=\dfrac{25}{4}\%=\dfrac{25}{400}=0.0625[/tex]
For John, [tex]r=6\dfrac{3}{4}\%=\dfrac{27}{4}\%=\dfrac{27}{400}=0.0675[/tex]
Amount in Jack's account after 19 years= [tex]7600e^{0.0625(19)}[/tex]
[tex]=7600e^{1.1875}\\\\=7600(3.27887376794)\\\\\approx\$24,919.44[/tex]
Amount in John's account after 19 years= [tex]7600e^{0.0675(19)}[/tex]
[tex]=7600(1+0.0675)^{19}\\\\=7600(3.45931245291)\\\\\approx\$26,290.77[/tex]
Difference = 26290.77-24919.44 = $ 1,371.33
John would have $1371.33 more in his account than Jack.

Complete question :
Kendall is making cupcakes for a party. She uses 1/8 of a 4-pound bag of sugar to make a batch of cupcakes. Each batch has 24 cupcakes.
Drag one expression next to each question. The correct expression for each row is a way to answer that question.
How many pounds of sugar does Kendall use for a batch of cupcakes?
How many pounds of sugar are used for each cupcake?
Answer:
1/8 * 4 = 0.5
0.5 ÷ 24 = 0.0020833 pounds
Step-by-step explanation:
The amount of sugar in pounds used for a batch of cupcake is : 1/8 of 4 pounds
1/8 * 4 pounds
= 0.5 pounds
Pounds of sugar used for each cupcake :
Number of cupcakes per batch = 24
Pounds of sugar per cupcake :
Pounds of sugar per batch / number of cupcakes per batch
0.5 pounds / 24
= 0.0020833 pounds

Answer: Inequality form : -19<x>3
interval notation:
(--19,3)
Step-by-step explanation:
Given: - 4x/7 > 10. Choose the solution set. {x | x < - } {x | x > - } {x | x > - } {x | x < - }
Answer:
{x | x < - 35 / 2}
Step-by-step explanation:
-4x / 7 > 10
Multiply both sides by 7
-4x /7 * 7 > 10 * 7
-4x > 70
Divide both sides by - 4
-4x / - 4 > 70 / - 4
x < - 35 / 2 (inequality sign changes)

A piece of machinery was purchased by a factory. It depreciates at 10percent every year. At the end of second year its value is rs 1,29,600.What is the cost price
Answer:
160000
Step-by-step explanation:
Let the cost price = x
At the end of the first price, it loses ten percent = 0.9x
At the end of the second year, it loses an extra ten = 0.9(0.9x)= 0.81x
0.81x=129600
x=160000

The ratio of the length to the width the official german flag is 5:3.Sanda is making 12 german flags for a cuiture show.Each flag she makes has a length of 20 centimeters . It takes her 4 hours to make all the flag. What is the width of each flag and the average amount of time it takes sandra to make each flag?
Answer: The width of each flag = 12 cm
The average amount of time it takes Sandra to make each flag = 20 minutes.
Step-by-step explanation:
Given: The ratio of the length to the width the official german flag is 5:3.
Let length = 5x, width = 3x
Length of each flag = 20 cm
i.e. [tex]5x=20\Rightarrow\ x=\dfrac{20}{5}=4\text{ cm}[/tex]
Then width of each flag = 3 x 4 = 12 cm
i.e. width of each flag = 12 cm
Total time to make 12 flags = 4 hours
Time taken to make 1 flag = [tex]\dfrac{4}{12}[/tex] hour
Time taken to make 1 flag = [tex]\dfrac{1}{3}[/tex] hour
1 hour = 60 minutes
Time taken to make 1 flag = [tex]\dfrac{1}{3}\times60[/tex] minutes = 20 minutes.
Hence, the average amount of time it takes Sandra to make each flag = 20 minutes.

y=-3x-4,
y=1/2x+3
now plug in any points for x for both equations. I will plug in both x as 0.
y=-3(0)-4
y=-4
(0,-4)
y=1/2(0)+3
y=3
(0,3)
We have points now to plot on a graph.
Continue what I did. Maybe plug in 1 for x for both equations.
Hope this helps!
Answer:
x= [tex]\frac{-8y -6}{7}[/tex]
Step-by-step explanation:
Step 1: Add (-1)/2x to both sides.
−3x − 4y + [tex]\frac{-1}{2}[/tex] x = [tex]\frac{1}{2}[/tex] x + [tex]\frac{-1 }{2}[/tex] x
Step 2: Add 4y to both sides.
[tex]\frac{-7}{2}[/tex] x - 4y + 4y = 3 + 4y
[tex]\frac{-7}{2}[/tex] x = 4y + 3
Step 3: Divide both sides by (-7)/2.
[tex]\frac{-7 }{2}[/tex] x
= 4y+3
[tex]\frac{-7}{2}[/tex] [tex]\frac{-7}{2}[/tex]
