The amount of money that Britta will pay is; SEK2500

Let the amount paid by Britta scabetala be x

Now, we are told that Britta scabetala half as much as Agda. Thus;

Amount paid by Agda = 2x

Now, Cornelia must pay SEK 1,500 less than Britta. Thus,

Amount paid by Cornelia = x - 1500

Agda must pay five times as much as Cornelia. Thus;

2x = 5(x - 1500)

2x = 5x - 7500

5x - 2x = 7500

The ways that you can maximize a tax-sheltered retirement program include:

1. when the contributions made by the employer are not taxable

2. when the employee has started making contributions early in life,

A tax-sheltered is a retirement savings plan that enables self-employed individuals and workers of tax-exempt organizations to invest pretax money to create retirement income. A dependable source of income in retirement, tax-sheltered annuities are made to pay out consistently throughout time.

The fact that employer contributions are tax-free is one of the best features of retirement programs. Only when an employee takes money out of their retirement accounts do taxes need to be paid. If the employee starts making contributions early in life, the plans also allow the employee the chance to maximize returns, which is another benefit that the employee can get from them.

104 ;108;112;116;120;124;128;132;136 ;140;144;148

Answer:

104, 108, 112, 116, 120, 124, 128, 132, 136, 140, 144, 148

Step-by-step explanation:

A multiple of 4 can generally be defined as divisible by 4.

We can define an equation for it: [tex]4n[/tex] where n is an integer.

From here we can see that if n=25, we have a number of 100 which indeed is a multiple of 4 since dividing it by 4 results in 25 which makes sense since 100 is the result of 4 * 25.

Now starting from 100 (excluding 100 since between 100 and 150), or n=25, we can increase the value of the number by 4, or n by 1 which is doing the same thing.

So start at 100, then 100+4 = 104, then 104+4=108 and so on... until you reach a number greater than or equal to 150, and if it is 150 make sure to exclude it since it says between 100 and 150 which implies it's excluding the end points.

This gives us a result of: 104, 108, 112, 116, 120, 124, 128, 132, 136, 140, 144, 148

The graph will be a shaded region above and including the straight line y = (3/2)x-1.

We are asked to graph the inequality y ≥ (3/2)x-1. Describing the graph of an inequality, it will be a region on one side of a straight line.

So first we need to sketch the straight line, y = (3/2)x-1.

So find two points (x, y) satisfying this equation of line because a line need at least two points.

x       y  

0       -1

2/3     0

So first sketch a line joining the points (0, -1) and (2/3,0). This line will lie below the origin. That is, origin lies on the region above this line.

So the line y = (3/2)x-1 divided the plane into two regions, one of which represents the inequality y ≥ (3/2)x-1. So to find this required region we will check if origin lies in the region for inequality.

Substituting (0, 0) into y ≥ (3/2)x-1,

0 ≥ -1, which is true.

Thus in the graph, the region for inequality is the region where the origin lies. Hence shade the region above the line y = (3/2)x-1. This is the graph of the inequality y ≥ (3/2)x-1.

The correct responses for the arithmetic and exponential sequence and function are;

1. First part; 32 pennies

Second part; Approximately 50 days

2. 24.6 gallons

3,738.5 minutes

3. $67.2

Approximately 24 months

4. 1106.14 gallons

66.56 minutes

The difference is 1 is an arithmetic sequence while 3 is an exponential function

An arithmetic sequence is a group of numbers in which the difference between subsequent terms is a constant

1. The given parameters are;

The initial amount Savannah placed in the piggy bank = 5 pennies

The amount given to Savannah each day = 3 pennies

Required;

First part;

The amount Savannah will have after 10 days

Solution;

The mathematical model for the situation is an arithmetic sequence or progression

The equation for an arithmetic progression is;

[tex]a_n = a_1 + (n - 1) \times d[/tex]

Where;

[tex]a_n[/tex] = The amount after n days

[tex]a_1 [/tex] = The first amount Savannah placed in the piggy bank = 5 pennies

n = The number of days

d = The common difference between the amount present in consecutive days = 3 pennies

The amount after 10 days is therefore;

[tex]a_{10} = 5 + (10 - 1) \times 3=32[/tex]

The money after 10 days is 32 pennies

Second part;

The number of days it would take for there to be $1.50 in the piggy bank.

Solution;

100 pennies = $1.00

Therefore;

$1.50 = 150 pennies

Which gives;

150 = 5 + (n - 1) × 3

(n - 1) × 3 = 150 - 5 = 145

(n - 1) × 3 = 145

n - 1 = 145 ÷ 3

n = 145 ÷ 3 + 1 ≈ 49.3 ≈ 50

It will take approximately 50 days for the amount in the piggy bank to be $1.50

2. The volume of the pool = 1,500 gallons

The initial amount of water in the pool = 5 gallons

The rate at which water enters the pool = 2 gallons in 5 minutes

Required;

First part

The volume of water in the pool after 50 minutes

Solution;

2 gallons in 5 minutes = (2/5) gallons/minute = 0.4 gallons/minute

Therefore;

[tex]a_{50} = 5 + (50 - 1) \times 0.4 =24.6[/tex]

After 50 minutes, 24.6 gallons will be in the pool

Second part;

The time it will take to fill the pool is given by the equation;

[tex]1500 = 5 + (n - 1) \times 0.4[/tex]

number

Which gives;

n = 3738.5

It will take 3,738.5 minutes to fill the pool

3. The formula for finding the amount in the account is the compound interest formula;

[tex]\displaystyle{A = P\cdot (1 + r)^n }[/tex]

Where;

A = The amount in the account after n months

P = The initial amount in the account = $50.0

r = The interest rate = 3.0%

n = The number of periods (months)

After 10 months, we have;

[tex]\displaystyle{A = 50 \times (1 + 0.03)^{10} \approx 67.2 }[/tex]

The amount in the account after 10 months is therefore, approximately $67.2

Second part;

Double the initial amount is 2×$50 = $100

Which gives;

[tex]100 = \displaystyle{50 \times (1 + 0.03)^{n} \approx 67.2 } [/tex]

Which gives;

n ≈ 23.45

Therefore it will take approximately 23.45 months or approximately 24 months for the amount to double

4. Using the exponential function formula, we have;

Number of 5 minutes in 50 minutes = 10

[tex] \displaystyle{1500 \times (1 - 0.03)^{10} \approx 1106.14} [/tex]

The water remaining after 50 minutes is approximately 1106.14 gallons

The time it takes for there to be less than 1,000 gallons in the pool is given as follows;

[tex] \displaystyle{ 1000= 1500 \times (1 - 0.03)^{n}} [/tex]

Which gives;

n = 13.3

Therefore;

The water in the pool will be less than 1000 gallons after 13.3, 5 minute periods or 13.3 × 5 minutes≈ 66.56 minutes

We calculate the ratio (in percentage) of 5.2cm to 4cm

5.2 : 4 = 1.3

Because 4cm is 1.3x less than 5.2, its percentage must also be 1.3x less than 96%

-> 4cm = 96% : 130% = approx. 73.85% (2 d.p)

Assuming they work until their cost become the same, obviously.

The difference between the first charge of painter A and painter B = 376 - 280 = 96.

The hourly cost difference between painter B and painter A = 15 - 12 = 3.

So, painter A in the first hour has 96 more dollars than painter B, and as every hour pass, the difference goes down by 3 (as painter B gets 3 more dollars every hour)

Therefore, it would take 96 : 3 = 32 hours for the cost to be the same

Recheck : After 32 hours, painter A has 376 + 32 x 12 = 760 (dollars)
painter B has : 280 + 15 x 32 = 760 (dollars)

The numerical value of the third number in an improper and mixed fraction form is 93/10 and 9 3/10 respectively.

Given the data in the question;

Let 'x' represent the third number

First, convert the numbers form mixed fractions to improper fractions

Sum of the three numbers = 24 4/5 = ( 24×5 + 4 )/5 = 124/5

First number = 8 2/3 = ( 8×3 + 2 )/3 = 26/3

Second number =  6 5/6 = ( 6×6 + 5 )/2 = 41/6

Now, to determine the third value, equate the sum of the three numbers to the total and solve for x

26/3 + 41/6 + x = 124/5

( 156 + 123 )/18 + x = 124/5

( 279 )/18 + x = 124/5

31/2 + x = 124/5

x = 124/5 - 31/2

x = ( 248 - 155 )/10

x = ( 93 )/10

x = 93/10

x = 9 3/10

Therefore, the value of the third number is 93/10 or 9 3/10.
