The length of a rectangle is 3 m longer than its width.
If the perimeter of the rectangle is 34 m, find its area.

Answer:

$824.56

Step-by-step explanation:

Use the compound interest formula which is A = P(1+r/n)^nt

1st using the given information we are going to find out values:
P is our initial amount of $500
r is the annual rate of interest (expressed as a decimal) 8% becomes 0.08.
n is how many times interest is compounded per year, in this case since its not stated we are going to assume its annually, so n is 1
t is how long the money is deposited (in years) so t is 6.5
A is our final amount

2nd plug in our values into the equation

Plugging all these values we get A = 500 (1 +0.08/1)^(0.08)(6.5)

A = $824.56

The percentage that each transaction contributed to the total transactions in the same account (Cash Account and Service Revenue) is computed as follows:

1. Service Revenue $900   = 8%

2. Owner's Equity, Barbara Hanson $2,200 = 19.8%

3. Accounts Receivable $750 = 6.8%

5. Note Payable $6,000 = 54.1%

6. Unearned Revenue $1,250 = 11.3%

Total cash receipts = $11,100

1. Cash $900 = 70.6%

4. Accounts Receivable $375 = 29.4%

Total $1,275

The percentage that each transaction contributed to the total transactions in the same account can be computed by taking the dollar value of the transaction over the total value of transactions in the same account and then multiplying by 100.

Percentage values show the degrees of relationship among variables.

The formula for computing percentage in this scenario is transaction value/total transactions value × 100%.

1. Cash $900 Service Revenue $900

2. Cash $2,200 Owner's Equity, Barbara Hanson $2,200

3. Cash $750 Accounts Receivable $750

4. Accounts Receivable $375 Service Revenue $375

5. Cash $6,000 Note Payable $6,000

6. Cash $1,250 Unearned Revenue $1,250

The following transactions occurred during July:

1. Received $900 cash for services provided to a customer during July.

2. Received $2,200 cash investment from Barbara Hanson, the owner of the business.

3. Received $750 from a customer in partial payment of his account receivable, which arose from sales in June.

4. Provided services to a customer on credit, $375.

5. Borrowed $6,000 from the bank by signing a promissory note.

6. Received $1,250 cash from a customer for services to be rendered next year.

Use the transactions to compute the percentage of each transaction relative to the total transactions in the same account.

The interest due on financing option is $307.50

What is interest on financing?

Interest on financing is the extra amount paid by the couple when their total payments are compared to the cash price of $6,230.

The total payments would be the 25% down payment plus the sum of the twelve monthly payments of $415 each

Down payment=cash price*25%

Down payment=$6230*25%

Down payment=$1,557.50

Total monthly payments=amount of each monthly payment*number of monthly payments

monthly payment=$415

number of monthly payments=12

Total monthly payments=$415*12

Total monthly payments=$4,980

Total payment under financing=Down payment +Total monthly payments

Total payment under financing=$1,557.50+$4,980

The area is:

A = (θ/2)*R^2

The circumference is:

C = θ*R

And the area of the circle when the angle is π/4 is: 39.25 cm^2

For a circle of radius R, the area is:

A = pi*R^2

where pi = 3.14

And the circumference is:

C = 2*pi*R

Now, remember that a circle has an angle of 2pi radians, then if we only define an arc in the circle, defined by an angle θ, the area of said arc will be:

A = (θ/2pi)*pi*R^2 = (θ/2)*R^2

And the circumference is:

C = (θ/2pi)*2pi*R = θ*R

Now, we want to find the area when the circle has a radius R = 10cm and θ = pi/4

Replacing that in the area equation, we get:

A = (pi/4/2)*(10cm)^2 = (3.14/8)*(10cm)^2 = 39.25 cm^2

If the three vertices of the rhombus are W(2,5),x(6,3),Y(2,1) then the area of the rhombus is 16 square units.

Given the three vertices of the rhombus are W(2,5),x(6,3),Y(2,1).

We are required to find the area of the rhombus when the fourth point Z is plotted.

We have to plot the points of the rhombus in the graph. We know that all the sides of the rhombus should be equal to each other. So by adjusting the blocks in the graph we will be able to plot Z as (-2,3).

In this way the diagonals are ZX and WY.

ZX=[tex]\sqrt{(3-3)^{2} +(6+2)^{2} }[/tex]

=[tex]\sqrt{64}[/tex]

=8 units

WY=[tex]\sqrt{(1-5)^{2} +(2-2)^{2} }[/tex]

=[tex]\sqrt{16}[/tex]

=4 units

Area of rhombus=1/2 *([tex]d_{1} *d_{2}[/tex])

=1/2* (8*4)

=8*2

=16 Square units.

Answer:

x = -9

Step-by-step explanation:

12 + 2x + 24 = 27 + x

(12 + 24) + 2x = 27 + x

36 + 2x = 27 + x

subtract 27 from both sides

36-27 + 2x = 27-27 + x

9 + 2x = x

subtract x from both sides

9 + x = 0

subtract 9 from both sides

x = -9

(the steps could've been faster but that shows the most work)

check:

12 + 2(-9) + 24 = 27 + (-9)

36 - 18 = 18

Step-by-step explanation:

This is the answer by definition.

The substitution property is demonstrated in the case of m∠AZF=m∠AZL+m∠LZF and m∠AZL+m∠LZF=m∠SZW+m∠LZF, so, m∠AZF=m∠SZW+m∠LZF.

In order to find the value of the unknown, the substitution property is a concept in algebra that is used to substitute the value of a given variable or quantity into an expression.

According to the substitution property of equality, "If two variables x and y are equal, then x can be substituted for y in any equation or expression, and y can be substituted for x in any equation or expression."

According to the question, m∠AZF=m∠AZL+m∠LZF and m∠AZL+m∠LZF=m∠SZW+m∠LZF, so by the substitution property, on substituting the value of  m∠AZL+m∠LZF in the first expression, we get, m∠AZF=m∠SZW+m∠LZF.

Answer:

98 degrees

Step-by-step explanation:

In a quadrilateral, we have 4 angles whose sum is 360 degrees which can be derived using the Exterior Angle Sum Theorem which essentially states that any convex polynomial will have a sum of 360 degrees for it's exterior angles.

Since we know that two of the angles are equal, we can just represent angle A and D as "x", and since they're congruent, and there is two of them, the sum can be represented as "2x"

So using all the known values we can set up the following equation:

[tex]2x+64+100=360[/tex]

Simplify on the left side

[tex]2x+164=360[/tex]

Subtract 164 from both sides

[tex]2x=196[/tex]

Divide both sides by 2

[tex]x=98[/tex]

Since we know that "x" represents both angle A and B, then the angle A is 98 degrees.

The answer is 492 feet.

If we picture the scenario as a right triangle, using trigonometric ratios, this problem can be solved.

cos 60° = x / 984

1/2 = x/984

x = 984/2

x = 492 feet

But X=1.33

By substituting

X=1.33, We have that

The values of the coefficients a, b and c in the equation is -2, 1 and -1 respectively.

An equation is an expression that shows the relationship between two numbers and variables.

An independent variable is a variable that does not depend on any other variable for its value whereas a dependent variable is a variable that depend on any other variable for its value.

Given the polynomial:

-2x³ - 7x² + 3x - 4

Simplifying:

Hence:

-2x³ - 7x² + 3x - 4 = (-2x² + x - 1)(x + 4)

The monthly payment is $796.40.

The total amount she would deposit is $286,705.51

The total interest earned is $513,294.49

The payments made by Jessica are known as deferred annuities. Deferred annuities are when a series of payments are made in exchange for an amount of money in the future.

The formula that can be used to determine the amount of monthly deposit is: future value / annuity factor

Annuity factor = {[(1+r)^n] - 1} / r

Where:

r = interest rate = 6%/12 = 0.5%

n = number of years = 30 x 12 = 360

Annuity factor = ](1.005^360) - 1] / 0.005 = 1004.515

Monthly payments = 800,000 / 1004.515 = $796.40

Total amount she would deposit = monthly payment x number of years x number of months in a year

$796.40 x 30 x 12 = 286,705.51

Total interest earned = value of the retirement account - total amount deposited

800,000 - 286,705.51 = 513,294.49
